Abstract

ABVD remains a standard chemotherapy for Hodgkin Lymphoma (HL) despite many efforts to demonstrate the superiority of other regimens. Bleomycin was proven marginally active in this combination (J Clin Oncol 22:1532–3, 2004) but adding significant toxicity. Response to ABVD is often slow and relapse rate of 20–30% is a concern. ABVD has never been directly compared to CHOP, the other global standard for other lymphomas that is composed of agents certainly active in HL. Current study is an update on our initial report of 2004 (Blood 104, 2004). In addition to extending the follow-up, we compared outcome after CHOP in a pilot series of previously untreated patients with a retrospective results of ABVD therapy at our institution. CR/CRu rates were 88 and 62% for CHOP and ABVD, respectively. In CHOP CS III/IV group, more patients had at least three risk factors (80%) than in ABVD CS III–IV group (40%). In contrast to ABVD, there were no deaths in CHOP group, but EFS was inferior. This might result from a higher risk level in CHOP patients. Toxicity of both regimens was mild: grade 3/4 leukopenia in 9%, grade 1/2/3 peripheral neuropathy in 6% of ABVD patients, and grade 3/4 neutropenia in 7% of CHOP patients. In conclusion, CHOP-21 is an active and low-toxic regimen in HL with risk factors. A prospective comparison of CHOP with a standard chemotherapy in a randomized study will be justified.
