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

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)

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

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

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

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)

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

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

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
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

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

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

Folate receptor alpha (FRα)
bull is a glycosylphosphatidyl-inositol-linked protein
bull overexpressed in solid malignancies eg breast lung and renal cancers
bull high FRα expression was associated with non-endometrioidhistology high grade and advanced stage of endometrialcarcinoma
bull This study aimed to identify patients with high-intermedaterisk determining FRα expression in the tissue samples

CONCLUSIONS
bull L1CAM is mostly expressed in Type II ECs being associated with TP53 mutations
bull Higher levels are seen in high-risk endometrial cancers particularly in pelvic and para-aortic lymph node metastases
bull triage biomarker for pelvic and para-aortic lymph node staging

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

Could biomolecular profiling on diagnostic biopsy already help in tailoring surgery
Jalid Sehouli
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)

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

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

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

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

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)

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

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

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

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
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
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
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
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 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

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

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
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

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
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

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 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

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

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

Folate receptor alpha (FRα)
bull is a glycosylphosphatidyl-inositol-linked protein
bull overexpressed in solid malignancies eg breast lung and renal cancers
bull high FRα expression was associated with non-endometrioidhistology high grade and advanced stage of endometrialcarcinoma
bull This study aimed to identify patients with high-intermedaterisk determining FRα expression in the tissue samples
