Evaluation of cisplatinum in Hodgkin's disease, clinical stages IA-IIIB, treated by combined therapy. Preliminary results

Cisplatinum is highly effective in numerous solid tumors and was evaluated in Hodgkin's disease clinical stages (CS) I/II. Sixty-five patients (43 male, 22 female; median age 25, with 12 patients under 16: CS IA-IIA 41, IB 5, IIB 19) were randomly assigned to one of the following arms (PAF87 protocol): 3 ABVD (doxorubicin, bleomycin, vinblastin, dacarbazin with methylprednisolone) cycles (ABVD arm) or 3 ABVD plus cisplatinum cycles (ABVD-Plt arm) followed by radiotherapy (RT); extended field (40 Gy) RT with a short paraortic field including the spleen (30 Gy) was then administered in the ABVD arm; extended field (30 Gy) without lombo-splenic port prophylaxis. RT was administered in ABVD-Plt arm when patients were in complete remission (CR) after chemotherapy (CT). Median follow-up was 35 months (6-62 months). During CT, 1 patients (ABVD-Plt) died from viral meningo-encephalitis; five patients (1 ABVD, 4 ABVD-Plt) stopped treatment because of emesis, of whom three receiving only 1.5-2.5 (ABVD-Plt) cycles, are still in CR after 13-60 months. Fifty-five patients (27 ABVD-Plt) were in CR after CT. Among the 27 ABVD-Plt patients, all in CR after RT, two died (one from myocardial infarction and one from immunoblastic lymphoma); one patient from the ABVD arm died from gastro-intestinal hemorrhage in 1st CR. No ABVD-Plt patient relapsed; 1 ABVD patient relapsed in non-irradiated area. At five years, actuarial survival/relapse-free survival was 96.1/90% and 88.2/100% for ABVD and ABVD-Plt patients, respectively.
