Autologous bone marrow transplantation in the treatment of poor prognosis non-Hodgkin's lymphomas.
Twelve patients with non-Hodgkin's lymphomas of poor prognosis were treated by TACC high-dose chemotherapy (cyclophosphamide 45 mg/kg/day X 4, cytosine arabinoside 200 mg/m2 i.v. q 12 hr X 7,6-thioguanin 100 mg/m2 p.o. X 7 and CCNU 200 or 250 mg/m2 p.o., single dose) followed by autologous bone marrow transplantation (ABMI) (infused dose: 853-20,000 CFU-c/kg). Patients were divided into 2 groups: those in primary therapy with high tumor load (group 1; 3 initial diagnoses, 3 relapses) and those in consolidation therapy for a low tumor load (group 2; 5 complete and 1 partial remissions). Results show that: (1) the aplasia following autologous bone marrow transplantation was short. Leukocyte (greater than 10(9)/1) and platelet (greater than 50 X 10(9)/1) recoveries were observed on day 12 (range, 9-19) and day 14 (range, 8-27). (2) In group 1 there were 3 complete remissions (8,21, 45+ months) and 3 failures, including 1 death to toxicity of TACC. The 3 remissions occurred in patients in primary therapy and overall survival of these patients from the time of initial diagnosis was 48+, 48+ and 60+ months. In group 2 there were 5 persisting complete remissions (12+ to 40+ months) and 1 failure. Overall survival of these patients was 23+, 24+, 27+, 42+ and 70+ months. In both groups failures were associated with contamination of the frozen marrow by tumor. The toxicity of the association TACC + ABMT was acceptable and dominated by the risk of pericardial effusion and infection. The latter was absent in group 2 and occurred in 5/6 cases in group 1. These preliminary results indicate that autologous bone marrow transplantation has a possible role in the aggressive treatment of non-Hodgkin's lymphomas of high-grade malignancy and that its use should preferentially be in the consolidation mode.
