High dose chemotherapy combined with autologous peripheral blood stem cell transplantation is the consolidation treatment for advanced lymphoma patients and approved for treating recurrent and refractory lymphoma by prolonging progression-free survival significantly while also improving quality of life. Evidences to date, have validated that changes of T-lymphocyte subsets after autologous stem cell transplantation associated closely with immunologic reconstitution, and have produced amazing effects in prognosis. Whether T-lymphocyte subsets changes could serve as an effective index for prognosis has been a serious question for lymphoma patients treated by autologous stem cell transplantation. In this study, the investigators explore the changes of T-lymphocyte subsets in lymphoma patients before and after autologous stem cell transplantation, and evaluate the significant effect of T-lymphocyte subsets changes in immunologic reconstitution and prognosis in these patients.
This is a retrospective, single-center, non-randomized, non-controlled study. This study aims to explore the effect of T-lymphocyte subsets changes in immunologic reconstitution and prognosis in lymphoma patients who were treated by autologous stem cell transplantation.
