  4. Learning Objectives • Assess emerging frontline approaches for patients with Hodgkin lymphoma • Evaluate the efficacy and safety data for novel agents in patients with relapsed/refractory Hodgkin lymphoma • Discuss strategies to mitigate adverse effects to improve long-term survival in Hodgkin lymphoma

  5. Hodgkin LymphomaIntroduction and Initial Therapy

  6. Case Study 1 • M.C. is a 23 yo woman who presents with painless swelling of a right supraclavicular lymph node. She was otherwise asymptomatic with a normal physical examination • A course of antibiotics was prescribed, without response • An FNA was performed and interpreted as consistent wit a reactive lymphoid population • An excisional lymph node biopsy was ultimately performed

  7. CD15 CD30 EBER CD3

  8. Staging and Pre-treatment Evaluation • PET/CT showed non-bulky stage IIA disease • CBC, CMP unremarkable • ESR 12 ml/hour • HIV negative • No bone marrow is performed • Echocardiogram and PFTs show no organ dysfunction • What is the optimal therapy for this patient?

  9. Case 1: How will you treat this patient? • ABVD x 6 cycles followed by 30 Gy radiation • ABVD x 4 cycles followed by 30 Gy radiation • ABVD x 2 cycles followed by 20 Gy radiation • ABVD x 4-6 cycles without radiation • Escalated BEACOPP +/- radiation

  10. Case 1: What if this patient was 73 years old instead of 23? • ABVD x 4 cycles followed by 30 Gy radiation • ABVD x 2 cycles followed by 20 Gy radiation • ABVD x 4-6 cycles without radiation • AVD x 4-6 cycles (omit bleomycin) +/- radiation • ChlVPP +/- radiation

  11. Epidemiology • ~9200 cases/year in US • ~1200 deaths • Median age 35 • Bimodal distribution • Slight male predominance • Incidence is stable Siegel, et al. CA Cancer J Clin. 2014; 64(1): 9-29.

  12. Clinical Presentation • 70% present with painless lymph node enlargement • Limited in 55%, Advanced in 45% • 30% will have “B” symptoms • Pruritus • Rare pain with alcohol ingestion • Sites of involvement • Nodal regions • Cervical/Supraclavicular (L>R) 60-70% • Mediastinal 60% • Axillary 25-35% • Hilar nodes 15-35% • Para-aortic 30-40% • Iliac 15-20% • Inguinal 8-15% • Mesenteric 1-4% • Other lymphoid organs • Spleen 30-35% • Waldeyer’s ring 1-2% • Extranodal sites (10-15%) • Liver 2-6% • Bone marrow 2-8% • Other organs (lung, bone) 10%

  13. Nodular lymphocyte predominant HL CD20 Pathologic Classification • Classical HL • Nodular sclerosis • Mixed cellularity • Lymphocyte rich • Lymphocyte depleted

  14. LR NS LD MC

  15. Preparation for chemotherapy Echocardiogram Pulmonary Function Tests, with DLCO Fertility considerations Initial Evaluation and Workup • History • Physical exam • Staging studies • PET/CT scan • Bone marrow (Can usually be omitted based on PET findings) • Labs • CBC with differential • Erythrocyte Sedimentation Rate • Albumin, LFTs, Ca++, HIV

  16. Treatment Radiation alone preferred for limited stage: 10 year FFP ~ 80% Advanced stage extrapolated from cHL +/- rituximab ABVD +/- rituximab R-CHOP Some suggest alkylators may be more effective (controversial) Rituximab alone is an effective option, particularly at relapse Late recurrences may occur Nodular Lymphocyte-predominant HL • 5% of Hodgkin lymphomas • Pathologically distinct from CHL • Clinically distinct from cHL • Indolent natural history • Male predominance (75%) • Median age in 30s • Increased risk among first degree family members • Limited stage in 75%, usually peripheral • Extranodal disease, B symptoms very uncommon • ~12% rate of high-grade transformation at 10y

  17. Nodular LP vs Classical HL: GHSG Trials HD4-HD12 Freedom from Treatment Failure Overall Survival NLPHL CHL NLPHL CHL Nogova, et al. JCO 2008

  18. Initial Treatment of Classical Hodgkin Lymphoma (cHL)

  19. Chemotherapy for cHL • MOPP developed at National Cancer Institute in 1964 • 54% freedom from progression at 10 years • Potentially sterilizing • Potentially leukemogenic • ABVD developed at Milan Cancer Institute in 1973 • Not sterilizing • Not associated with MDS or leukemia DeVita NEJM ‘03

  20. MOPP versus ABVD for Advanced HL Overall Survival Failure-free Survival 5 year OS MOPP-ABVD 75% ABVD 73% MOPP 66% 5 year FFS MOPP-ABVD 65% ABVD 61% MOPP 50% Canellos, et al. NEJM. 1992

  21. Treatment Intensification: Escalated BEACOPP versus ABVD Viviani, et al. NEJM. 2011

  22. Risk Factors in Advanced Stage CHL • Age ≥45 • Male Gender • Stage IV • Hemoglobin <10.5 g/dL • Leukocytosis >15k/mm3 • Lymphopenia <600/mm3 or 8% • Hypoalbuminemia <4.6 Moccia, et al. JCO 2012; 30(27): 3383-3388.

  23. Advanced Stage disease • ABVD x 6 cycles • Outstanding questions • Selection of high-risk patients for treatment intensification • Role of PET-adapted therapy • Incorporation of novel agents

  24. Treatment of Limited Stage cHL

  25. Risk Stratification: Adverse factors in Limited Stage Disease EORTC GHSG Large mediastinal mass Extranodal disease >3 nodal regions Elevated ESR • Large mediastinal mass • Age >50 • >4 involved sites • ESR> 30 with B sx OR >50 without B sx

  26. Combined Modality Therapy is Superior to Radiation Alone in Early Favorable Disease Ferme et al. N Engl J Med 2007; 357: 1916-27.

  27. Combined Modality Therapy allows Reducing Chemotherapy Cycles and Radiation Field Ferme et al. N Engl J Med 2007; 357: 1916-27.

  28. Beware the Late Effects of Therapy Breast Cancer Incidence Ng et al. J ClinOncol 2002, 20(8): 2101-2108; De Bruin et al. J ClinOncol 2009 , 27(26): 4239-4246.

  29. Beware the Late Effects of Therapy Angina Pectoris All Cardiac Events Myocardial Infarction Aleman, et al. Blood 2007, 109(5): 1878-1886.

  30. German Hodgkin Study Group : HD10 trial • No risk factors: Large mediastinal mass, extranodal disease, >3 nodal regions, elevated ESR CS I - II withoutriskfactors* ABVD ABVD ABVD ABVD ABVD ABVD ABVD ABVD ABVD ABVD ABVD ABVD 30 Gy IF 20 Gy IF 30 Gy IF 20 Gy IF

  31. Less is more: The GHSG HD10 trial Engert et al. N Engl J Med 2010; 363(7): 640-652.

  32. Chemotherapy alone for Limited-stage cHL • Study excluded patients with bulk • (M:T ratio >.33 or disease >10cm) • Unfavorable = ESR ≥ 50 mm/hr, age ≥ 40, > 3 sites, MC/LD Stage I/II HL (N = 399) Favorable (N = 123) Unfavorable (N = 276) 35Gy STNI ABVDx4-6 ABVDx2+STNI ABVDx4-6 Primary endpoint: 12 year overall survival

  33. Chemotherapy Alone Versus Radiation-containing Therapy at 12 Years • OS at 12-years • ABVD 94% • XRT/CMT 87% (HR 0.4; p=0.04) • FFDP at 12-years • ABVD 87% • XRT/CMT 92% (HR 3.03; p=0.01) Meyer, et al. N Engl J Med 2012; 366(5): 399-408.

  34. Are These Data Relevant in 2014? NO • Subtotal nodal radiotherapy is not the modern standard of care and leads to increased radiation exposure compared to current involved field/nodal techniques • XRT likely didn’t cause late infections, Alzheimer’s disease or drowning YES • Though we radiate lower volumes today, modern radiation in HL often includes the breasts, lungs, skin/soft tissues, and coronary ostia. • ABVD alone produced 12-year overall survival of 94%, which is excellent • This OS and FFDP is virtually identical to the GHSG HD11 trial results at 5 years using modern CMT with IFRT in the same population

  35. Can Interim PET Scans be Used to Direct use of Radiation Therapy? H10 F 1 ABVD + INRT 30 Gy (+ 6 Gy) H10 U 2 ABVD PET R R PET - 2 ABVD 2 ABVD - + 2 BEACOPPesc + INRT 30 Gy (+ 6 Gy) + 2 ABVD + INRT 30 Gy (+ 6 Gy) 2 ABVD PET PET 4 ABVD 2 ABVD 2 BEACOPPesc + INRT 30 Gy (+ 6 Gy) Raemaekers, et al. J ClinOncol, 2014, 32: 1-8.

  36. Who Should Receive Radiation?Not one size fits all • Current data support combined modality therapy for bulky limited stage disease • For non-bulky patients, choice of therapy should be informed by patient age, tumor location and patient preference • Further data anticipated regarding the role of PET-adapted therapy

  37. Treatment of Limited Stage disease • Favorable • ABVD x 2 cycles plus 20Gy IFRT • ABVD x 4-6 cycles without XRT (for selected patients) • Unfavorable, non-bulky • ABVD x 4 cycles + 30 Gy IFRT • ABVD x 6 cycles without XRT (for selected patients) • Unfavorable, bulky • ABVD x 6 cycles plus 30-36 Gy IFRT • ABVD x 4 cycles without XRT if interim PET negative (for selected patients) • Major ongoing questions • PET-adapted therapy • Incorporation of novel agents

  38. The Challenge of Treating Older Adults with Hodgkin Lymphoma

  39. Advanced Stage HL in Older Adults (E2496: ABVD/Stanford V) Overall survival Failure-free survival 90% 58% 74% 48% Probability Probability P=0.002 P<0.0001 Year Year <60 yr ≥ 60 yr • 24% of older patients developed bleomycin lung toxicity • Treatment-related mortality: 9.3% vs. 0.3%, p<0.001) Evens et al. BJH, 2013, 161(1): 76-86.

  40. Limited Stage HL in Older Adults (GHSG HD10-HD11: ABVD x4 + IFRT) Overall Survival Progression-free Survival Time to HL death Time to HL treatment failure Boll et al. J ClinOncol , 2013, 31(12): 1522-1529.

  41. 100 0 Prognostic factor(s) 1 Prognostic factor(s) 2 Prognostic factor(s) 75 Percent survival 50 25 0 0 30 60 90 120 150 180 Time in Months Chicago Elderly HL Prognostic Model • Adverse Risk factors: • ADL loss • >70 years Event-free survival Overall survival Bleomycin lung toxicity 32% (Mortality: 25%) Evens, et al. Blood 2013, 122(21).

  42. Recommendations for Managing Older Adults with HL • Outcomes inferior to younger patients • Increased toxicity and treatment-related mortality • Take great caution regarding bleomycin lung toxicity and neutropenic infections • Low threshold to omit bleomycin (AVD) • Short course therapy if possible • Consider myeloid growth factor support • Non-ABVD/AVD options include ChlVPP, CHOP • Clinical trials preferred • Ongoing studies examining incorporation of brentuximab vedotin into frontline therapy

  43. Targeted Therapy and New Treatment Approaches

  44. Case Study 2 32 yo woman was diagnosed with stage IV cHL a year ago. She was treated with ABVD and achieved a complete response. Today, she presents with fatigue and enlarged right cervical lymph node measuring 2 x 2 cm. Imaging studies showed PET avid lesions above and below the diaphragm, with the largest nodal mass measuring 3 x 2 cm. Bone marrow biopsy was negative. Echocardiogram showed LVEF of 60%.

  45. Case 2: You Would Recommend: • Brentuximabvedotinx 16 doses followed by ASCT • ICE x 2-3 cycles followed by ASCT • BEACOPP X 6 cycles • DHAP x 2-3 cycles followed by ASCT • GND x 2-3 cycles followed by ASCT

  46. Case 2 (continued) • The patient received 3 cycles of ICE and achieved a CR. This was followed by stem cell collection, BEAM, and stem cell re-infusion (ASCT). • One year later, she had enlarged nodes above and below the diaphragm, and a biopsy of a left inguinal node confirmed the presence of relapsed HL.

  47. Case 2: You Would Recommend: • Brentuximabvedotin x 16 doses followed by allogeneic stem cell transplant • Brentuximabvedotin up to 16 doses, unless disease progression or prohibitive toxicity • Brentuximabvedotinx 4 then PET/CT. If CR continue for at least 8 doses and a maximum of 16 doses, followed by observation • Clinical trial
