ABSTRACT
We retrospectively analyzed clinical and pathological features, treatments, and prognoses in 28 patients with newly diagnosed peripheral T-cell lymphoma, not otherwise specified (PTCL-NOS) in Niigata University Medical and Dental Hospital. Of them, 16 were males and 12 were females, and their median age was 62.5 (range, 26-88) years. The International Prognostic Index was high-intermediate/high in 68% of patients. Twelve patients were treated with CHOP/THP-COP and nine with third-generation chemotherapy regimens. At a median follow-up period of 30 (range: 1-164) months, the 2-year overall survival and progression-free survival rates were 61% and 44%, respectively. Further investigation of novel agents for treating PTCL-NOS is warranted.

A 62-year-old man with CHOP refractory adult T-cell leukemia/lymphoma (ATLL) received anti-CC chemokine receptor 4 antibody (mogamulizumab) combined with CHOP and achieved complete remission. At 71 days after the final administration of mogamulizumab, he received umbilical cord blood transplantation (CBT) using reduced intensity conditioning. Umbilical cord blood engraftment was confirmed on day16. Grade II acute graft-versus-host disease (GVHD) was diagnosed on day60 and was controlled by administration of methylprednisolone. There was no evidence of relapse at 9 months after CBT. Ratios of regulatory T cells in CD4 positive T cells were remarkably low during all of these periods. Since mogamulizumab reduces regulatory T cells, the frequency and severity of acute GVHD were reported to be increased in patients administered mogamulizumab before allogenic stem cell transplantation. Further experiences are needed for selecting optimal donor sources, the portability period and GVHD prophylaxis for patients using mogamulizumab before allogeneic stem cell transplantation.
