Autologous bone marrow transplantation in 44 patients with aggressive non-Hodgkin's lymphoma at University ''La Sapienza'' of Rome

High dose therapy followed by infusion of autologous bone narrow has become a major treatment option for an increasing number of poor prognosis non-Hodgkin's lymphoma (NHL) patients. In our study we analyzed the outcome of autologous bone marrow transplantation (ABMT) in 44 high grade NHL patients transplanted at our institution between 1985 and 1992. Median age was 31 years (range 12-61); nineteen were in partial remission (PR) after first line chemotherapy and 25 in sensitive relapse (SR). Of the 25 patients transplanted in SR, 14 relapsed after a median time of 5.5 months (range 1-26), 8 are in complete remission after a median follow up of 41.5 months and three died from toxicity. Of the 19 patients grafted in PR, 11 are alive and progression free after a median follow up of 52 months, while 8 relapsed at a median time of 5 months. The overall progression free survival (PFS) projected at 6 years is 35% with a 47% PFS for patients transplanted in PR and 28% for patients in SR. In conclusion, high dose therapy and ABMT has achieved widespread use as salvage therapy for patients with relapsed/refractory high grade NHL. In particular, our experience confirms that myeloablative treatment is a safe and well tolerated procedure for patients in PR, that may be easily applied as early salvage therapy without major toxicities.
