  1. Management of Advanced Stage Hodgkin Lymphoma Michael Crump, MD, FRCPC Princess Margaret Hospital University of Toronto Toronto, Canada

  2. Outline of this presentation • Definition and incidence • Historical results and the need for change • Recent trials of new approaches • Nodular lymphocyte predominant HL • Late effects in advanced stage HL • Conclusions

  3. Decline in mortality rate from HL in North America MOPP ABVD Aisenberg, Blood, 1999; Reprinted from Ries; NIH Publ 97-2789, 1997

  4. HL Outcomes – Continued Improvement Brenner, et al. Blood, 2008 US SEER database: >16,000 pts 1980-2004 all 25-34y >60y 1980-84 2000-04 Relative survival: 5 y 73% 85% 10 y 62% 80%

  5. Advanced HL: definitions • NA intergroup: stage III, IV; relapse after prior extended field radiotherapy • British: B symptoms (any stage); II with bulky mediastinal mass; stage III, IV • German Hodgkin Study Group: • Stage IIB + E extension or LMM; III, IV • Early, unfavourable: stage I,II with E lesions, LMM, ↑ ESR, > 3 sites

  6. Prognostic factors in advanced HL • Hasenclever-Diehl index NEJM 1998 • >5000 patients (13% stage I-IIB) • Complete data for model: ~1600 • 7 clinical variables: • Age > 45 y • Male sex • Hb <105g/L • Stage IV • Albumen < 40 g/L • WBC > 15 • Lymphocytes <0.6 or <8%

  7. Biologic prognostic factors? • Epstein-Barr Virus (EBV) ~25-35% +ve by IHC (LMP-1), ISH (EBER-1) More common: males, older age (>45), mixed cellularity histology Older adults → less favourable outcome • BCL-2 • Cytokine levels • Cytokine gene polymorphisms • Tumour microenvironment etc…

  8. Previous Therapeutic Observations in Advanced Disease ABVD is superior to MOPP, and equal to but less toxic than alternating MOPP-ABVD Canellos G, et al, NEJM, 1992, 2002 ABVD is equivalent to alternating and hybrid multidrug regimens, with less toxicity Johnson PW, et al, JCO 2005

  9. Recent Therapeutic Observations in Advanced Stage Disease ABVD is equivalent to MOPP/ABV but has less serious/fatal toxicity • Duggan D et al; JCO 2006 Esc BEACOPP is superior to COPP-ABVD • Diehl V, et al: NEJM, 2003

  10. Advanced Hodgkin Lymphoma ABVD vs MOPP/ABV Hybrid Intergroup CALGB, ECOG, SWOG, NCIC ABVD MOPP/ABV p n 433 419 CR% 76 80 0.16 Progression % 10 11 5 y FFS% 63 66 0.42 5 y OS% 82 81 0.82

  11. Definition and incidence • Historical results and the need for change • Recent trials of new approaches • Nodular lymphocyte predominant HL • Late effects in advanced stage HL • Conclusions

  12. New concepts evaluated in phase II trials to improve results in HL • Consolidation with high-dose therapy and ASCT (high risk pts) • Optimization of combined modality therapy: Stanford V • Intensification with non-cross-resistant agents, increased dose intensity + G-CSF • escalated BEACOPP, other regimens

  13. Not useful • Intensification of COPP-ABV with IMEP (ifos, MTX, etoposide, prednisone) vs C-A GHSG HD6 trial Ann Oncol 2004 • Intensification with ASCT in high risk HL after CR/PR to ABVD/other x 4 cycles Federico M, JCO 2003

  14. Recent Randomized Trials of Novel Regimens in Advanced Hodgkin Lymphoma N pts CR(%) Progr’n (%) 5 y FFTF OS (yr) Esc BEACOPP 466 96 2 87 91 (5) BEACOPP 469 88 8 76 88 COPP-ABVD 260 85 10 69 83 ABVD 99 70 12 65 84 (5) BEACOPP 98 81 2 78 92 COPP-EBV-CAD 98 69 10 71 91 ABVD 261 67 5 85 90 (5) Stanford V 259 57 6 73 92 CR: complete response rate; FFTF: freedom from treatment failure; OS: overall survival

  15. BEACOPP Escalated mg/m2 day • Bleomycin 10 IV 8 • Etoposide 200 IV 1-3 • Doxorubicin 35 IV 1 • Cyclophos 1200 IV 1 • Vincristine 1.4 IV 8 • Procarbazine 100 PO 1-7 • Prednisone 40 PO 1-14 Cycle length 21 days G-CSF day 8-15

  16. BEACOPP is superior to COPP-ABVD • Recent HD9 update: follow-up > 9 yrs • 10 y FTFF and OS favour escBEACOPP over BEACOPP, COPP-ABVD Engert A, et al, J Clin Oncol 2009

  17. GISL HD 2000BEACOPP v ABVD v CEC Federico M, J Clin Oncol 2009

  18. Should escBEACOPP now be the standard? …maybe not yet • Toxicity vs (COPP-)ABVD: • Greater male, female infertility (vs ABVD: fertility is unaffected) • More significant Hb, plt toxicity; fever/infection • Higher secondary AML risk? (second cancers: no difference) • Elderly (age >60): more toxic, not more effective

  19. Other trials of this strategy • GHSG HD12: 8 escBEACOPP vs 4 esc + 4 BEACOPP Advanced disease, age <65 No difference in 5 y OS, FFTF • EORTC-NCIC-GELA HD8: 4 esc + 4 BEACOPP vs 8 ABVD --accrual recently completed

  20. ABVD remains the standard for advanced HL Doxorubicin 25 mg/m2 d1, 15 Bleomycin 10 mg/m2 d1, 15 Vinblastine 6 mg/m2 d1, 15 Dacarbazine 375 mg/m2 d1, 15

  21. ABVD remains the standard for advanced HLPractical points: • Are pulmonary function tests required? • Bleomycin lung toxicity: up to 30% of patients; high case fatality rate (esp elderly) • No PFT at baseline, unless older or underlying lung disease (smokers) • In follow-up: if symptoms (cough, dyspnea, fever) or if > 6 cycles ABVD planned • Omission of bleo does not seem to compromise treatment

  22. ABVD remains the standard for advanced HLPractical points: • Is G-CSF (neupogen) required? • Not generally: several cohort studies of Rx regardless of treatment-day ANC→ no increase febrile neutropenia • ? Association with bleomycin toxicity • Should be used for pts at high risk of febrile neutropenia: elderly, bone marrow involvement, HIV+ • PMH recipe: daily x4-5, starting D5, A cycle • (not needed with each treatment)

  23. Hodgkin Lymphoma Older Patients HL age distribution (y) • 16 – 60 80 % • > 60 15 % • > 70 7 %

  26. Hodgkin Lymphoma Older Patients Chemotherapy recommendations • No special regimen superior • ABVD remains the gold standard • If drugs must be omitted due to underlying organ dysfunction • Consider 7 – 8 drug combinations, then drop offender(s) • Anticipate increased toxicity • Hematologic • Neurologic • Pulmonary • Cardiac • Enhance supportive care • G-CSF

  27. FDG PET?

  28. Outcome of HL according to interim FDG PET and IPS Gallamini A, J Clin Oncol 2007

  29. RCT of Observation vs RT for Patients with Bulky HL and Negative Post Chemo PET Scan Bulk: > 5 cm long axis* Chemo: VEBEP 6 cycles RT: 32 Gy Negative PET: no uptake Positive PET: “uptake in …abnormal area” 260 patients 2000-2006 n = 160 randomized stage I, II  2/3 B symptoms  ½ Radiation: mantle, inv Y, para-aortic Picardi M, et al. Leuk Lymph, 2007

  30. Relapse: Chemo alone: 11/80 (14%) Chemo + RT: 2/80 (2.5%) Picardi,et al. Leuk Lymph, 2007

  33. Patients with FDG avid lesions following chemotherapy should have a biopsy, if PET scan is to be used to modify treatment: Variable false positive rates: 21 +ve scans→10 benign Zinzani, Hematologica 2007 27 +ve scans→ 4 benign Schaefer, Radiology2007

  34. Definition and incidence • Historical results and the need for change • Recent trials of new approaches • Nodular lymphocyte predominant HL • Late effects in advanced stage HL • Conclusions

  35. Pathology:Nodular lymphocyte predominant HL

  36. NLPHL: German experienceNogova, et al. J ClinOncol 2008 LP HL(%) classical HL(%) n=394 n= 7904 p CR 87 82 .003 PD 0.3 3.9 .0001 relapse 8.1 8.0 late rel7.4 4.7 .02 death 4.6 9.6 .0004 second Ca 2.5 3.7 .27

  37. Nodular LP Hodgkin Lymphoma • Favourable prognosis with current therapies according to disease extent • No increase in relapse vs cHL • No increase in secondary malignancies → treatment as per advanced cHL GHSG J Clin Oncol 2008

  38. Definition and incidence • Historical results and the need for change • Recent trials of new approaches • Nodular lymphocyte predominant HL • Late effects in advanced stage HL • Conclusions

  39. Long-Term Cause-Specific Mortality of Patients Treated for Hodgkin’s Disease J Clin Oncol 2003

  40. GELA H89 Trial: Chemotherapy +/- radiation for advanced stage HL;Causes of Death • N = 533, median f/u 10 yrs • 129 deaths: Hodgkin lymphoma PD/rel 60 (46%) • treatment 15 • salvage treatment 7 Second cancer 24 (19%) Cardiovascular 1 Unknown/not spec. 22 Ferme C, Blood 2006

  41. Lung Cancer – Dramatic Effects of Age, Treatment, Smoking History >1 ppd smoker others RT>5 Gy AA chemo RR RR Treatment no no 1.0 6.0 yes no 20.2 7.2 no yes 16.8 4.3 yes yes 49.1 7.2

  42. Change in Systemic Chemotherapy? Example of secondary AML(JNCI, 2006) • >35,000 1 yr HL survivors • 14 cancer registries (Nordic, N America) • pts treated 1970-2001 • Excess absolute risk higher in 1st 10 yrs of follow-up • Decline in AML incidence for pts treated after 1985, • esp among those getting chemotherapy • --more widespread use of non-alkylator • based therapy (ABVD)

  43. General population

  44. Conclusions • ABVD 6-8 cycles remains standard for advanced HL outside of a clinical trial • Use of interim PET to modify therapy is a question, not the answer • Radiation should not be routinely administered, nor forgotten: role in LMM, E lesions… • Decisions re: adopting more toxic regimens involves trade-offs for patients
