2. THE MAIN INTENT: LESS TOXICITY At least 85% of Hodgkin patients can anticipate a cure. The charge: cure even more patients with the least impact on their well being

3. EARLY STAGE HODGKIN HISTORY 5-10 yr. relapse rate lower for chemotherapy + IF RT than EF RT alone (JCO 24: 3128-35, 2006; JC0 25: 3495-3502, 2007; NEJM 357: 1916-27, 2008) No difference in OS at 4-5-yrs. between ABVD alone and ABVD + RT for patients with limited stage non-bulky HL (Blood 104: 3483-89, 2004; JCO 23: 4634-42, 2005) RT is associated with late 2nd malignancies and cardiovascular events especially after 10 yrs.

15. Summary • 602 pts registered between 2003 and 2010 • 75% PET-negative at central review after ABVD x 3 • In the randomized PET-negative population, 3 yr PFS is 92.8% IFRT and 90% NFT • Risk difference -3% is within the maximum allowable difference of -7% Radford J, et al. Blood. 2012;120: Abstract 547.

16. Commentary These data are similar to those reported from Argentina several years ago for all stages of disease when PETs were obtained after 3 cycles (Pavlosky, et al.) CAUTION: Were the deaths in the IFRT arm ‘flukes’ and not related to the IFRT? If so, would the data and conclusions be different. Radford J, et al. Blood. 2012;120: Abstract 547.

24. Overall Commentary Combined modality therapy (CMT) improves disease control by 4%-7% Could this difference in control have been obviated by the use of PET scans after one cycle of therapy since there was a 7% difference in PET negative results between cycles 1 and 2, much less cycle 3? The relatively long term outcomes associated with IFRT remain to be clarified

30. Background National Cancer Database (NCDB) Joint program of the Commission on Cancer and the American Cancer Society Prospectively collected; Nationwide outcomes database covering 75% of all newly diagnosed cancers (>1,500 U.S. hospitals); Not population-based dataset Not geographically limited (care in all states included) Reflects contemporary treatment programs RT specifics available for analysis (modality, dose, fx, volume/site)

31. Aims of the Study Primary Endpoint: Determine relationship between use of RT and overall survival in patients with early-stage Hodgkin’s Disease Secondary Endpoints: Determine the trends of utilization rates of RT Determine other factors (socioeconomic factors, timing of chemotherapy, co-morbid conditions) associated with overall survival

32. Methods Evaluated clinical features & survival outcomes The association between RT use, co-variables, and outcome was assessed in a multivariate Cox proportional hazards model. Survival was estimated using the Kaplan-Meier method. • Hodgkin’s Disease, Stage I/II, diagnosed 1998-2011 (N = 41,420) • Median f/u = 6.4 years; • Median age = 37 years (range: 18-90) • Multi-agent chemotherapy given to 96% of the pts • Did NOT receive Radiation Therapy • (N = 20,897, 51%) • Received Radiation Therapy as part of CMT • (N = 20,523, 49%) • Median RT dose = 30.6 Gy

33. Univariate Survival Analysis (OS)

34. Factors Associated with Overall Survival (MVA)

35. Overall Survival by RT use 84% 76%

36. RT Utilization 56% 1998 ` 41% 2011

37. Conclusions Largest contemporary dataset of patients with early- stage HD (n=41,420) The use of RT is associated with improved 10-yr OS (84% vs. 76%, HR=0.51, p<0.00001) BUT THIS MAY BE DUE TO A POPULATION WITH AN INHERENT BETTER PROGNOSIS Utilization of RT has decreased by 15% from 1998 to 2011 (5641%; not part of initial treatment strategy) Specific factors (socioeconomic, insurance status, facility type) were associated with underutilization of RT which may be targeted to improve patient access to RT, IF RT IS INDEED INDICATED

41. Response Results at End of Front-Line Therapy a Assessed using Cheson 2007 b Patient had a Grade 5 event of pulmonary toxicity prior to the end of front-line therapy • Response results at end of front-line therapy: • ABVD cohorts: 21 of 22 CR (95%) • AVD cohorts: 24 of 25 CR (96%) • In addition, 1 patient withdrew consent and 3 patients were lost to follow-up prior to completion of front-line therapy and were not evaluable for response Ansell SM, et al. Blood. 2012;120: Abstract 798.

42. CONCLUSIONS: EARLY STAGE HL PET SCANS HAVE ALLOWED THE REDUCTION OF CHEMOTHERAPY CYCLES IN EARLY STAGE HL. COMBINED MODALITY THERAPY (CMT)PROVIDES ABOUT ABOUT A 5% (+/- 3%)ADVANTAGE OVER CHEMOTHEAPY ALONE IN PFS ALTHOUGH OS ADVANTAGE REMAINS TO BE PROVEN. THE LONG TERM TOXICITY OF LIMITED OR NODAL FIELD RT IS STILL UNKNOWN. ACUTE TOXICITY MAY PLAY A ROLE IN REDUCING OS? PET SCANS AFTER 1 CYCLE MAY REDUCE THE PFS ADVANTAGE OF CMT. PATIENT SELECTION IS CRITICAL IN DECIDING WHAT RX TO ADMINISTER. WILL BRENTUXIMAB VEDOTIN REPLACE THE ‘NEED’ FOR RT?
