Turkish Bone Marrow Transplantation Registry (TBMTR) was established in 1995. Since 1992, data of adult lymphoma patients from fifteen national transplantation centers were collected and analyzed by TBMTR. A total of 437 adult lymphoma patients (185 Hodgkin's and 252 non-Hodgkin's lymphoma) undergoing autologous hematopoietic stem cell transplantation (HSCT) were registered in TBMTR from 1992 to 2002. Peripheral blood as stem cell source was used in 94% of the transplantations. Non-TBI (total body irradiation) conditioning regimens were administered in 88% of the cases. The 100-day transplantation-related mortality (TRM) was 11% in relapsed and 11% in primary refractory Hodgkin's lymphoma patients whilst TRM was found to be 9% and 30% in non-Hodgkin's lymphoma patients in first remission and in primary refractory cases, respectively. Infection was the most common cause of TRM. 10-year and 5-year survival rates were 50% and 49% in relapsed cases and primary refractory cases with Hodgkin's lymphoma, respectively; while in non-Hodgkin's lymphoma patients 10-year survival rate was 65% in cases in first remission, 7-year survival rate was 50% in sensitive relapse, 2-year survival rate was 0% in resistant relapse and 3-year survival was 24% in primary refractory cases. In conclusion, TBMTR results are comparable to EBMT and IBMTR results. Therefore, autologous HSCT may provide long-term survival in patients with Hodgkin's lymphoma as well as in patients with non-Hodgkin lymphoma in first remission and in sensitive relapse.
