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

Medical and Biotech [MESH] Definitions
Clinical Trial, Phase Iii
Work that is a report of a pre-planned, usually controlled, clinical study of the safety and efficacy of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques after phase II trials. A large enough group of patients is studied and closely monitored by physicians for adverse response to long-term exposure, over a period of about three years in either the United States or a foreign country.
Clinical Trials, Phase Iii As Topic
Comparative studies to verify the effectiveness of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques determined in phase II studies. During these trials, patients are monitored closely by physicians to identify any adverse reactions from long-term use. These studies are performed on groups of patients large enough to identify clinically significant responses and usually last about three years. This concept includes phase III studies conducted in both the U.S. and in other countries.
Precise and detailed plans for the study of a medical or biomedical problem and/or plans for a regimen of therapy.
Leukemia, Myeloid, Chronic-phase
The initial phase of chronic myeloid leukemia consisting of an relatively indolent period lasting from 4 to 7 years. Patients range from asymptomatic to those exhibiting ANEMIA; SPLENOMEGALY; and increased cell turnover. There are 5% or fewer blast cells in the blood and bone marrow in this phase.
Clinical Trial, Phase Ii
Work that is a report of a pre-planned, usually controlled, clinical study of the safety and efficacy of diagnostic, therapeutic, or prophylactic drugs, devices, or techniques based on several hundred volunteers, including a limited number of patients, and conducted over a period of about two years in either the United States or a foreign country.
