Impact of high-dose salvage therapy (BEAM) on overall survival in younger patients with advanced large-cell lymphomas entered into BNLI trials

Abstract

The survival of two cohorts of patients with stage III/IV large-cell lymphomas treated by CHOP has been compared. In the first cohort of 88 patients (1974-1982), high-dose therapy with autologous bone marrow transplantation (ABMT) was not available as salvage therapy and in the second cohort of 87 patients (1987 1992). This was the recommended salvage for patients with disease that was still chemosensitive to conventional-dose therapy. The actuarial overall survivals at five years were 40% and 44% in the first and second cohorts, respectively, indicating that the availability of A BMT had made little impact. Of the 62 patients in the second cohort who failed CHOP therapy, 8 died before second-line chemotherapy could be given. I refused more therapy, and 8 were considered unsuitable for further combination chemotherapy. Seven patients with localized disease remaining received local radiotherapy. Of the 38 patients given salvage therapy, 14 had chemoresistant disease. Only 9 patients received high-dose BEAM chemotherapy and ABMT, and 7 remain disease-free. ABMT was restricted to a highly select patient group, and as a result more widespread application of this strategy might result in only a modest further improvement.
