A multicentre archive

PROJECT TYPE DESIGN amp TIME PERSPECTIVE

Observational Patient archive Prospective (a first phase of three years is planned followed byfurther three years

TREATMENT

SINCE THIS IS A ARCHIVE TREATMENT IS NOT DICTATED BY A PROTOCOL HOWEVER TREATMENT HAS TO BE ADMINISTERED

ACCORDING TO A IRB-APPROVED LOCAL PROTOCOL (except for the countries where conservative treatmentcan be given outside a IRB-approved study because considered as a standard procedure)

INCLUSION CRITERIA

- Conservatively treated endometrial cancer- Informed consent to personal data processing- Existence of an IRB-approved local protocol that allows conservative treatment to be performed (orstatement that such treatment is considered as a standard)

INTERVENTIONS amp OUTCOME MEASURES

Data collection - PRIMARY OUTCOME MEASURES proportion of complete regression duration of responsefrequency and pattern of relapse frequency of metachronous ovarian cancer tumor-related deathsData collection - SECONDARY OUTCOME MEASURES treatment related morbidity frequency ofspontaneous pregnancies frequency of pregnancies after ART pattern of residual disease ondefinitive surgical specimens

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Wortman et al submitted

bull 3250 randomized to the experimental arm

bull Average time between

bull Randomization and receipt of all requested materials

58 days (1-16 days)

bull Randomization and determination of the profile

102 days (1-23 days) - excl LUMC 122 days (5-23 days)

bull In 5 of 32 patients (156) pathology review took gt2 weeks

Discussion

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

What are the potential questions

bull Prognostic factors PFS OS

bull Predictive factors - early stage vs advanced stage

- lymph node status - complete resection in advanced disease - timing of surgery (neodjuv vs adjuvant)

- subsequent therapies (morbidity and tumor control)

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

of Fx Dose Per Fx at Surface (Gyfx)

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

PROJECT TYPE DESIGN amp TIME PERSPECTIVE

Observational Patient archive Prospective (a first phase of three years is planned followed byfurther three years

TREATMENT

SINCE THIS IS A ARCHIVE TREATMENT IS NOT DICTATED BY A PROTOCOL HOWEVER TREATMENT HAS TO BE ADMINISTERED

ACCORDING TO A IRB-APPROVED LOCAL PROTOCOL (except for the countries where conservative treatmentcan be given outside a IRB-approved study because considered as a standard procedure)

INCLUSION CRITERIA

- Conservatively treated endometrial cancer- Informed consent to personal data processing- Existence of an IRB-approved local protocol that allows conservative treatment to be performed (orstatement that such treatment is considered as a standard)

INTERVENTIONS amp OUTCOME MEASURES

Data collection - PRIMARY OUTCOME MEASURES proportion of complete regression duration of responsefrequency and pattern of relapse frequency of metachronous ovarian cancer tumor-related deathsData collection - SECONDARY OUTCOME MEASURES treatment related morbidity frequency ofspontaneous pregnancies frequency of pregnancies after ART pattern of residual disease ondefinitive surgical specimens

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Discussion

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

bull Prognostic factors PFS OS

bull Predictive factors - early stage vs advanced stage

- lymph node status - complete resection in advanced disease - timing of surgery (neodjuv vs adjuvant)

- subsequent therapies (morbidity and tumor control)

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

L1-cell adhesion molecule (L1CAM)

bull is a transmembrane protein of the immunoglobulin family bull Promotes tumor cell proliferation migration invasion and metastasis1

bull Activates the extracellular signal-regulated kinase (ERK) pathway that is involved in motility- and invasion1

bull Elevated serum or tissue expression was associated with poor prognosis in patients with endometrial cancer 2

bull L1CAM expression reported as an independent predictor for PFS and OS and distant recurrence 3

bull Immunohistochemistry data from PORTEC-1 and PORTEC -2 showed an increased risk of distant recurrence and pelvic nodal relapse associated with high L1 CAM expression 4

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

bull In 5 of 32 patients (156) pathology review took gt2 weeks

Discussion

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Discussion

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

of Fx Dose Per Fx at Surface (Gyfx)

Experimental arm

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

of Fx Dose Per Fx at Surface (Gyfx)

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Short Course Adjuvant Vaginal Cuff Brachytherapy (VCB) in Early

Endometrial Cancer Compared to Standard of Care (SAVE)

David Gaffney MDPhD FASTRO FACR

Please consider supporting PORTEC IV

Background

bull Endometrial cancer is common

bull Early stage cancers (stage I and II) gt80

bull Adjuvant brachytherapy is commonly utilized

bull Many women donrsquot get treated (gt23 of elderly women)

bull Brachytherapy and pelvic exams are stressors

bull Local control is high with vaginal brachytherapy (gt98 in multiple trials)

bull Lower dose regimens (lower BEDs) have local control gt99

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

bull be less intensive on radiotherapy resources

bull be more cost effective

bull result in less morbid

bull and have non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

Randomization

2 Fractions11 Gy at the surface

(73 Gy at frac12 cm for a 3 cm cylinder)

Standard of care brachytherapy1 7 Gy frac12 cm x 32 5-55 Gy frac12 cm x 43 6 Gy surface x 5

Objectives

bull Primary Objective

bull Evaluate patient reported outcomes (PROs) using the Global Health Score from the QLQ30

bull Secondary Objectives

bull Evaluate cost effectiveness

bull Evaluate CTCAE v4 toxicities

bull Document any pattern of recurrence

bull Evaluate PROs for vaginal bladder and bowel symptoms using the EORTC EN24

Dose Prescription

We propose a study of 2 fractions of vaginal cuff brachytherapy of 11 Gy at

the surface (73 Gy at frac12 cm depth) given one week apart

Experimental arm

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Hypothesis a shorter treatment course

bull will result in greater compliance

bull permit more patients to receive adjuvant brachytherapy

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Statistics

bull The EORTC QPQ-C30 reference values manual (Scott 2008) gives the means and SD of the Global Health Status in genitourinary cancer patients as 626 plusmn222 points

bull Differences of 10 points in the global scales are widely viewed as being clinically significant when evaluating the results of randomized clinical trials (Cocks 2008 Maringwa 2011)

bull We therefore assume a standard deviation of 222 points and an equivalence margin of 10 points for power calculations

bull With these assumptions a total sample size of 108 will provide 90 power

Conclusions

2 fractions of VCB compared to standard of care may allow

bull Greater compliance

bull Non-inferior patient satisfaction as measured by patient reported outcomes (PROs)

bull More patients to receive VCB

bull Be less intensive on radiotherapy resources

bull Be more cost effective

bull Maintain a high rate of local control

Discussion

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge

Feasibility of pathology logistics

Wortman et al submitted

bull 3250 randomized to the experimental arm

bull Average time between

bull Randomization and receipt of all requested materials

58 days (1-16 days)

bull Randomization and determination of the profile

102 days (1-23 days) - excl LUMC 122 days (5-23 days)

bull In 5 of 32 patients (156) pathology review took gt2 weeks

Discussion

bull First randomized clinical trial that uses molecular-integrated risk profiles for HIR EC logistical challenge

bull Satisfactory patient acceptance rate of 35 (1 in 3 eligible women) range 0-57

bull Measures taken to further optimize the workflow of the determination of the risk profile

bull Involves microscopy and IHC and DNA analyis

bull Change from Sanger to NGS

bull At start 1 now 2-3 NGS runs per week

Essential factors

Prompt request and sending of the materials (slides and blocks)

Very dedicated pathologists

Conclusions

Randomized clinical trial using a molecular-integrated risk profile to determine treatment bull Logistical challenges but it can be donebull Women value the concept of more individualized risk

assessment and treatment

Trials needed to bring the molecular factors into clinical decision making

bull Prognostic who should be treated reduce overtreatment

bull Predictive which characteristics predict response to (chemo) therapy

bull Specific treatment POLE-mutated and MMRd tumors are responsive to immune checkpoint inhibition

bull Potential for pre-surgery treatment assignment

bull Preferably use clinicopathological and molecular integrated profiles

bull Double classifiers are a clinical challenge
