Resumo:  Trials have demonstrated that high-dose escalation followed by autologous transplantation can promote better long-term survival as salvage treatment in malignant lymphomas. The aim of the present nonrandomized clinical trial was to demonstrate the role of high-dose cyclophosphamide (HDCY) in reducing tumor burden and also to determine the effectiveness of HDCY followed by etoposide (VP-16) and methotrexate (MTX) in Hodgkin's disease plus high-dose therapy with peripheral blood progenitor cell (PBPC) transplantation as salvage treatment. From 1998 to 2000, 33 patients with a median age of 33 years (13-65) affected by aggressive non-Hodgkin's lymphoma (NHL) (60.6%) or persistent or relapsed Hodgkin's disease (39.4%) were enrolled and treated using high dose escalation (HDCY + HDVP-16 plus HDMTX in Hodgkin's disease) followed by autologous PBPC transplantation. On an "intention to treat" basis, 33 patients with malignant lymphomas were evaluated. The overall median follow-up was 400 days (40-1233). Thirty-one patients underwent autografting and received a median of 6.19 x 10(6)/kg (1.07-29.3) CD34+ cells. Patients who were chemosensitive to HDCY (N = 22) and patients who were chemoresistant (N = 11) presented an overall survival of 96 and 15%, respectively (P<0.0001). Overall survival was 92% for chemosensitive patients and 0% for patients who were still chemoresistant before transplantation (P<0.0001). Toxicity-related mortality was 12% (four patients), related to HDCY in two cases and to transplant in the other two. HDCY + HDVP-16 plus HDMTX in only Hodgkin's disease followed by autologous PBPC proved to be effective and safe as salvage treatment for chemosensitive patients affected by aggressive NHL and Hodgkin's disease, with acceptable mortality rates related to sequential treatment.
