Abstract
In this prospective, multicenter, non-randomized study for patients with stage I–II Hodgkin lymphoma, group 1 (without risk-factors [RF]) had three cycles of ABVD chemotherapy (adriamycin, bleomycin, vinblastine, and dacarbazine) and group 2 (any of bulk, extranodal site, >3 regions, raised erythrocyte sedimentation rate [ESR]) and group 3 (B-symptoms) received four cycles. Involved field radiotherapy (IFRT) 30 Gy was given after adequate chemotherapy response. Five-year overall survival and freedom from progression (FFP) were 96% (95% confidence interval [CI] 91–98%) and 90% (84–94%), respectively. Five-year FFP was 97% (90–99%), 89% (75–95%), and 73% (52–86%) for groups 1, 2, and 3, respectively. In patients with RF, chemotherapy responses of complete response unconfirmed (CRu), partial response (PR), and stable disease (SD) were associated with FFP of 90%, 86%, and 62% (p=0.17), and CR/no CR on functional imaging with FFP of 90%/67%, respectively (p=0.05). The 97% FFP in group 1 compares favorably with previously reported results from cooperative trial groups. Intensification of therapy warrants study in patients with RF and a poor chemotherapy response.
