Abstract

Peripheral T cell lymphomas (PTCL) are less responsive to anthracycline-containing regimen such as CHOP and carry a poor prognosis. In this prospective study, we investigated gemcitabine, cisplatin, and dexamethasone (GDP) combined with methotrexate (MTX) and pegaspargase (PEG-L) as front-line treatment in PTCL. Eligible newly diagnosed PTCL patients received 4 cycles of the GDP-ML chemotherapy every 28 days. After 4 cycles, responding patients continued to receive either autologous stem cell transplantation or the MTX/cytarabine (MA) regimen for consolidation. This trial is registered with www.​chictr.​org.​cn (ChiCTR-ONC-12002055). A total of 65 patients were enrolled with a median follow-up of 38.5 months. The overall response rate (ORR) was 55.4%, and complete remission rate (CR) was 33.8%. The median overall survival (OS) was 16 months, and the 1-year and 2-year OS were 59.1% and 38.2%, respectively. The median PFS was only 8 months. The main adverse event was hematologic toxicity: 50% patients showed grade III/IV neutropenia. GDP-ML for the first-line treatment of PTCL patients is an effective induction regimen compared with standard CHOP, and the toxicity was more significant but acceptable. However, future studies exploring new drug combinations are warranted to overcome relapse after remission. ClinicalTrials.​gov Identifier: NCT02987244
