TRANSPLANTATION Myeloablative allogeneic hematopoietic stem cell transplantation for non-Hodgkin lymphoma: a nationwide survey in JapanFrom the Hematology and Hematopoietic Stem Cell Transplantation Division, National Cancer Center Hospital, Tokyo, Japan; the Department of Hematology, Tottori University Hospital, Tottori, Japan; the Department of Internal Medicine, Nagoya Daini Red Cross Hospital, Nagoya, Japan; the Department of Hematology/Oncology, Kyoto University Hospital, Kyoto, Japan; the Division of Hematology, Tokai University Hospital, Isehara, Japan; the Department of Hematology, Tokyo Metropolitan Komagome Hospital, Tokyo, Japan; the Department of Hematology and Oncology, JA Aichi Showa Hospital, Konan, Japan; the Department of Internal Medicine, Sapporo Hokuyu Hospital, Sapporo, Japan; the Department of Hematology, Hamanomachi Hospital, Fukuoka, Japan; the Department of Cell Therapy and Transplantation Medicine, University of Tokyo, Tokyo, Japan; the Department of Hematology, Meitetsu Hospital, Nagoya, Japan; the Department of Pathology, Cancer Institute of Japanese Foundation for Cancer Research, Tokyo, Japan; the First Department of Internal Medicine (Medicine and Biosystemic Science), Kyushu University Graduate School of Medical Sciences, Fukuoka, Japan; and the Department of Hematology, Toranomon Hospital, Tokyo, Japan.
We retrospectively surveyed the data of 233 patients who underwent myeloablative allogeneic hematopoietic stem cell transplantation (allo-HSCT) for non-Hodgkin lymphoma (NHL). Donors were HLA-matched relatives in 154 patients (66%) or unrelated volunteers in 60 (26%). Ninety patients (39%) were in complete remission. One hundred ninety-three (83%) received a total body irradiation (TBI)-based regimen, and 40 (17%) received a non-TBI-based regimen. Acute graft-versus-host disease (GVHD) occurred in 155 (67%) of the 233 evaluable patients; grade II to IV in 90 (39%), and grade III to IV in 37 (16%). Treatment-related mortality (TRM) was observed in 98 patients (42%), and 68% of them were related to GVHD. In a multivariate analysis, chemoresistance, prior autograft, and chronic GVHD were identified as adverse prognostic factors for TRM. Relapse or progression of lymphoma was observed in 21%. The 2-year overall survival rates of the patients with indolent (n = 38), aggressive (n = 111), and lymphoblastic lymphoma (n = 84) were 57%, 42%, and 41%, respectively. In a multivariate analysis, chemoresistance, prior autograft, and prior radiotherapy were identified as adverse prognostic factors for overall survival. Although myeloablative allo-HSCT represents an effective therapeutic option for patients with NHL, more work is still needed to decrease TRM and relapse. (Blood. 2006;108:382-389)
