About

Peripheral T-cell Lymphoma (PTCL) is a heterogenic malignancy with poor outcome. Five-year PFS and OS for these patients received classic CHOP regimen (cyclophosphamide, vincristin, doxorubicin and prednisone) is less than 30%.High dose intensive chemotherapy doesn't demonstrate better response. At present, there is no standardized treatment protocol for this kind of lymphoma. So, clinical trials are encouraged by NCCN for those patients.

Full description

For the less efficacy of CHOP or CHOP-like regimen, multi-drug combination strategy has been the therapy tendency in PTCL. The novel regimen IVE/MTX (ifosfamide, etoposide，epirubucin/methotrexate)-ASCT(autologous stem-cell transplantation ) was piloted for patients eligible for intensive treatment, followed by auto-stem cell transplantation. Five-years PFS (progression-free survival) and OS (overall survival) were 52% and 60% respectively, significantly improved compared with the historical group treated with anthracycline-based chemotherapy. The encouraged results were extended to the peripheral T cell lymphoma-non specified (PTCL-NOS). Former studies reported that GDP (gemcitabine, cis-platinum, and dexamethasone) compared with CHOP as the therapy strategy for PTCL-NOS (not otherwise specified). The response rate was 78.57% in GDP group and 60.00% in CHOP group respectively. DFS (disease-free survival) was 9.79 and 4.2 months in above two groups. They concluded that GDP is superior with CHOP. The main side-effect of two regimens is hematological toxicity. Furthermore, high-dose combined with ASCT has been the first-line therapy for PTCL. However, only about 30% patients with PTCL have chance to receive ASCT for multiple reasons. So it is urgent to explore new combination-therapy regimen to improve the outcome for patients with PTCL.

The aim of our study is to compare the response and survival rate of CEOP/IVE/GDP (cyclophosphamide, vincristin, epirubucin and prednisone/ ifosfamide, epirubucin, and etoposide/ gemcitabine, cis-platinum, and dexamethasone) with those of CEOP regimen, looking forward to its superiority in efficacy and safety for the newly diagnosed adult patients with PTCL.
