The purpose of the study was to evaluate and compare the efficacy and
tolerability of two cytostatic regimens-chlorambucil, vinblastine, pro
carbazine and prednisone (ChlVPP) vs. ChlVPP alternating with doxorubi
cin, bleomycin, vincristine and dacarbazine (ABOD). One hundred eligib
le patients with stage IIIA-IVB Hodgkin's disease were randomized to e
ither ChlVPP or ChlVPP alternating with ABOD. The complete response ra
te (CR) was 80% in both treatment groups. After a median follow-up tim
e of 59 months, 42 (84%) of the patients in the ChlVPP-treated group w
ere in CR compared with 39 (78%) treated with ChlVPP/ABOD. The estimat
ed five-year overall and relapse-free survival rates were 87% and 74%,
respectively, for the ChlVPP-treated patients and 76% and 73% for the
ChlVPP/ABOD-treated patients, The ChlVPP regimen showed a slightly be
tter subjective tolerance than the ChlVPP/ABOD regimen. The given dose
intensity was very close to optimal, and equal for the two regimens.
