Outline of this talkOutline of this talkOutline of this talkOutline of this talk
• prognostic factors following disease recurrence • role of local radiotherapy
• current results with ASCT
• strategies to improve ASCT outcome
• standard approaches – chemotherapy
• second transplants- reduced intensity allogeneic SCT

Recurrent HLRecurrent HL
• ~10-20% of early stage (I and II), 20-40% of pts with advanced disease
• Refractory: progression during or within 3 mos of completing therapy

Prognostic factors at relapsePrognostic factors at relapse
• age
• B symptoms
• performance status
• time to recurrence
• anemia
• extranodal sites
• primary treatment (RT v chemo)
… etc

Factors associated with poor outcome:
• anemia• advanced stage• early relapse

Management of very late relapseManagement of very late relapse
• No risk factors (normal hemoglobin, limited stage), CR1 >5 y
→ chemotherapy + IFRT (EFRT?)
• eg BEACOPP x 4
• ASCT reserved for subsequent relapse

Primary Refractory HL
• New lesions or progression of prior lesions within 3 months of completing therapy

Radiation After Relapse – Consider Radiation After Relapse – Consider it an Optionit an Option
• radiation as component of combined modalitytherapy for HL reduces the risk of local recurrence
• HL often recurs in nodal sites, and in sites not previously irradiated
• long-term disease control has been reportedafter RT for recurrent HL after primarychemotherapy (or CMT)

Pro• young patient population – going for cure• HL similar to other indolent B-cell lymphomas
- long survival after relapse- demonstrated GV–lymphoma effect in CLL,
follicular NHL
Con• published data from myeloablative alloSCT:
- high treatment-related mortality- GVHD, regimen-related
- little impact of GVHD on relapse rate

ConclusionsConclusions
• Outcome of second-line therapy is determined by clinical factors, as much as by treatment– Not to mention biology…
• ASCT is the standard of care for all patients (suitable age, PS) with few exceptions– Late relapse, localized… think CMT
![Page 48: Management of Recurrent of Relapsed and Refractory Hodgkin Lymphoma](https://reader035.vdocument.in/reader035/viewer/2022062322/56814cf9550346895dba0f16/html5/thumbnails/48.jpg)
ConclusionsConclusions
• Novel agents are currently being tested that may be incorporated into primary or second line treatment– HDAC inhibitors, mTOR, antibody-chemo
conjugates…
• Reduced intensity transplants need to be evaluated in carefully conducted trials

ConclusionsConclusions
• Numerous treatment options available– but cure is but cure is uncommonuncommon: take time to manage expectations, : take time to manage expectations,
discuss realistic goalsdiscuss realistic goals
• Disease control possible with radiation (sometimes) and chemotherapy (sometimes)– Keep it simple; reserve combinations for when transplant is
goal (chemosensitive)
• Exciting new agents entering or in clinical trials!– encourage patient, physician participation
• Allotransplant needs further study in well-designed phase II trials
