[Autologous peripheral blood stem cell transplantation combined with autologous bone marrow transplantation for treating refractory lymphoma].

This study was aimed to investigate the differences of therapeutic efficiencies, side effects and recovery rates of immune function in refractory lymphoma patients treated with autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT), autologous bone marrow transplantation (ABMT) and combination of APBHSCT with ABMT (APBHSCT + ABMT) by retrospective analysis, and to evaluate the merits and demerits of 3 kinds of transplantation for treatment of refractory lymphoma. 68 patients with malignant lymphoma were treated with autologous hematopoietic stem cells transplantation. Out of 68 patients 10 cases were treated with autologous bone marrow transplantation (ABMT), 46 cases were treated with autologous peripheral blood hematopoietic stem cell transplantation (APBHSCT), and 12 cases were treated with autologous peripheral blood hematopoietic stem cells transplantation combined with autologous bone marrow transplantation (APBHSCT + ABMT). The results indicated that the therapeutic response rates and survival rates at 1, 3, 5 years for each transplant regimen were 90% and 75%, 57.1%, 33.3%; 86.4% and 74.4%, 54.2%, 38.1%; 83.3% and 72.7%, 55.6%, 40%. The times of ANC > or = 0.5 x 10(9)/L were 13, 11 and 9 days, times of platelet >/= 20 x 10(9)/L were 17, 14 and 10 days. The recovery rates of T cell subtypes in patients received ABMT, APBHSCT and APBHSCT + ABMT on 3 months, 6 months, 1 year were (0%, 33.3%, 60%), (10.8%, 32%, 73.9%), (27.3%, 55.6%, 85.7%) respectively. In conclusion, the efficacy and side effects of APBHSCT + ABMT as compared with ABMT and APBHSCT are roughly the same, but ABMT + APBHSCT can result in more rapid hematopoietic reconstitution and less restrictions with contributes to widen choice of transplant regimen for patients with alder age and impaired hematopoietic functions.
