High dose chemotherapy and autologous bone marrow transplantation in refractory Hodgkin's disease.

Seventeen patients with Hodgkin's disease (HD) were treated with high-dose chemotherapy followed by autologous bone marrow transplantation (ABMT). Eleven patients were resistant to initial therapy. Three patients had relapsed and were still responders to second or third line therapy. Three patients had relapsed but were progressing under second or third line therapy. Pre-ABMT chemotherapy included high dose cyclophosphamide in all patients (50 mg Kg-1 day-1 bolus for 4 days), most often associated with BCNU or CCNU, aracytine and 6 thioguanine. Four patients received additional TBI (10 Gy). In 9 patients complete remission (CR) was achieved, 4 failed to respond and 4 cases were not evaluable due to early death. Among CR patients, 2 died from late toxicity, 4 relapsed between the 2nd and 5th months, but 3 patients remain in CR, off therapy at 25+, 43+, and 66+ months, including 1/11 initially resistant and 2/6 who had relapsed. There were 9 treatment related deaths: 6 due to infection, 1 cardiac failure and 2 multiorgan failure. The high complete response rate in these heavily pretreated patients suggests that there may be an indication for high dose therapy earlier in resistant HD. Moreover under such conditions, treatment related morbidity would be expected to be lower.
