Clinical analysis of 25 patients with aggressive peripheral T-cell lymphoma in advanced stage treated with autologous stem cell transplantation

To investigate the outcomes of autologous stem cell transplantation (ASCT) for patients with aggressive peripheral T-cell lymphoma (PTCLs) in advanced stage. The clinical data of 25 patients in complete remission (CR) with aggressive PTCLs received ASCT from May 1997 to June 2013 were retrospectively analyzed. ① Of the 25 cases, 16 were unspecified PTCL (PTCL-U), 4 with angioimmunoblastic T cell lymphoma (AITL), 3 with anaplastic large cell lymphoma (ALCL) and 2 with hepatosplenic T cell lymphoma (HSTL), with a median age of 30(12-54) years old. Ratio of male to female is 16∶9. The distribution of stages was 8 cases with stage Ⅲ and 17 patients with stage Ⅳ. Nine patients presented with bone marrow involvement. Before ASCT, 18 patients were in CR1 and 7 patients were in CR2. ②Two patients with HSTL in stage ⅣB and IPI score 4/5 in CR1 relapsed and died within 12 months after ASCT. At a median follow-up of 38 (range 14-110) months, the estimated 3-year probability of PFS and OS for the other 23 patients was (6
