Long-term results of conventional-dose salvage chemotherapy in patients with refractory and relapsed Hodgkin's disease (Croatian experience).

BACKGROUND: The aim of this study was to analyze outcome of patients with Hodgkin's disease (HD) in whom first-line chemotherapy with mustine/vincristine/procarbazine/prednisone (MOPP) had failed. PATIENTS AND METHODS: From January 1982 to December 1989 among 210 patients treated with MOPP and radiotherapy to initial bulky sites, 65 patients were primary refractory to or relapsed after initial treatment. RESULTS: Twenty-nine of 65 patients (44%) were primary refractory to initial chemotherapy, 20 relapsed within 12 months after complete remission (CR) and 16 relapsed after CR that lasted more than 12 months. Patients with primary refractory HD and early relapse (<12 months after CR) were treated with doxorubicin/bleomycin/vinblastine/darcarbazine. In patients with late relapse (>12 months after CR) MOPP was repeated. The median follow-up for all patients was 115 months. The overall response rate was 63%. Thirty-three patients (51%) achieved a second CR and eight patients (12%) partial response. Remission rate was greatest in patients with late relapse (CR >12 months) (75 versus 55% for early relapse versus 35% for primary refractory HD) (P <0.01). At 10 years, overall and failure-free survival rates were 21 and 16%, respectively. Patients who were in first remission longer than 12 months had a superior overall survival (37 versus 18% for early relapse) and failure-free survival (24 versus 10% for early relapse). No patient with primary refractory HD was alive beyond 52 months after initial treatment failure (P <0.01). Main prognostic factors were duration of the first remission and tumor bulk at relapse. CONCLUSIONS: Our results confirm previous observations that a significant proportion of patients with HD who experience induction treatment failure cannot be cured with conventional treatment and probably need more aggressive therapy.
