High-dose melphalan with autologous bone marrow transplant. Treatment of poor prognosis tumors

Abstract

Seventeen patients were treated with high-dose melphalan with autologous bone marrow transplant (ABMT) and cyclophosphamide pretreatment. All of the patients had marrow reconstitution. Although there was one death caused by infection, high-dose melphalan with ABMT causes toxicity that is generally acceptable, and can achieve a high-response rate, but with responses of short duration in tumors resistant to standard-dose combination chemotherapy. In other poor-prognosis tumors that are sensitive to chemotherapy, or can be debulked surgically, or locally irradiated, high-dose melphalan with ABMT given as late intensification therapy may significantly prolong time to relapse, and ultimately prolong survival.
