Peripheral T-cell lymphoma (PTCL) carries a poor prognosis with conventional treatment. We retrospectively analyzed data from 45 patients with PTCL who received high-dose therapy and autologous stem cell transplantation (HDT/ASCT) from 1990 to 2008 in our center. Eighteen patients underwent HDT/ASCT in complete remission to induction chemotherapy (CR1), and 27 patients underwent HDT/ASCT in other disease statuses. The median follow-up was 113.5 months (range 52.6-261.0) for surviving patients. The 5-year overall survival (OS) and progression-free survival (PFS) were 64 and 60 %, respectively. The 5-year OS for patients in CR1 and in other disease statuses was 89 and 47 %, respectively (P = 0.002), and 5-year PFS was 83 and 43 % (P = 0.007). In the subgroup excluding anaplastic large cell lymphoma, patients transplanted in CR1 also had significantly better 5-year OS (82 vs. 37 %, P = 0.009) and PFS (82 vs. 33 %, P = 0.008) than those transplanted in other disease statuses. Multivariate analysis showed that CR1 status was the only significant prognostic factor for OS (P = 0.040) and PFS (P = 0.040). These results support the use of HDT/ASCT consolidation in CR1 for PTCL patients. Prospective randomized trials are necessary to confirm the efficacy of this approach.
