Multicentre phase II study of the CyclOBEAP regimen for patients with peripheral T-cell lymphoma with analysis of biomarkers.

Abstract

Peripheral T-cell lymphoma (PTCL) has a poorer prognosis than diffuse large B-cell lymphoma (DLBCL). We administered the CyclOBEAP regimen (cyclophosphamide, vincristine, bleomycin, etoposide, doxorubicin, prednisolone) to patients with DLBCL, and reported its safety and efficacy. Here, we report the results of a multicentre phase II study of the CyclOBEAP regimen in patients with PTCL. In addition, NME1 remained a prognostic factor for survival, as shown in patients who were treated with CyclOBEAP. There were 84 eligible patients and the median age was 54 years. The 5-year overall survival (OS) rate was 72% and progression-free survival (PFS) rate was 61%. The 5-year OS was 93% among the anaplastic large-cell lymphoma cases, 74% among the angioimmunoblastic T-cell lymphoma cases, and 63% among the cases of PTCL-not otherwise specified. When the patients were divided according to the International Prognostic Index or Prognostic Index for PTCL, the 5-year OS and PFS rates did not significantly differ among the risk groups. Positivity for NME1 was found to be a significant independent prognostic factor. Grade 4 neutropenia was observed in 80 patients and thrombocytopenia in nine patients. Our results suggest that the CyclOBEAP therapy is safe and effective for PTCLs. Furthermore, the NME1 protein may be an important prognostic factor in PTCL.
