Treatment of malignant lymphoma in 100 patients with chemotherapy, total body irradiation, and marrow transplantation.

ABSTRACT

Between July 1970 and January 1985, 100 patients with malignant lymphoma were treated with high-dose chemoradiotherapy and bone marrow transplantation. Twenty-eight of the 100 are alive and the actuarial probability of disease-free survival 5 years from transplantation is 22%. The most common reason for treatment failure was disease recurrence, with an actuarial probability of 60%. A proportional hazards regression analysis showed that the likelihood of disease-free survival was less in those patients transplanted in resistant relapse and in those previously treated with chest radiotherapy. Neither disease histology (Hodgkin's disease, high-grade lymphoma or intermediate-grade lymphoma), nor source of marrow (syngeneic, allogeneic, or autologous) significantly influenced either disease-free survival or probability of relapse. The use of high-dose chemoradiotherapy and marrow transplantation appears to offer a better chance for long-term survival than any other form of therapy for young patients with disseminated malignant lymphoma whose disease has progressed after initial combination chemotherapy. The best results with marrow transplantation were obtained in patients transplanted in early relapse or second remission who had not received prior chest radiotherapy.
