P-Gemox Regimen as First-line Chemotherapy in NK/T Lymphoma Patiens
- Conditions
- Lymphoma, Extranodal NK-T-Cell
- Interventions
- Registration Number
- NCT02533323
- Lead Sponsor
- Sun Yat-sen University
- Brief Summary
This prospective study was conducted to evaluate the efficacy and safety profiles of first-line combined gemcitabine, oxaliplatin, and Pegaspargase (P-Gemox) in newly diagnosed, nasal type, extranodal natural killer/T-cell lymphoma.
- Detailed Description
Treatment P-Gemox dosages were as follows: days 1, 30 min intravenous infusion of 1250 mg/m2 gemcitabine; day 1, 2h intravenous infusion of 85 mg/m2 oxaliplatin; day 1, deep intramuscular injection of 2500 U/m2 PEG-ASP at three different sites. The regimen was repeated every 2 weeks for a maximum of six cycles. Stage IE/IIE patients underwent four cycles induction chemotherapy, followed by involved-field radiotherapy after got CR, PR or SD. Three-dimensional conformal radiotherapy was done by linear accelerator at 2.0 grays (Gy) per daily fraction with 5-6 weeks. The involved- field radiation (IFRT) dose was 50-56 Gy. Stage IIIE/IVE patients patients underwent at least two cycles treatments unless there was disease progression or unacceptable side effects, or withdrawal of patient consent. Primary tumor radiotherapy was recommended after they achieved CR.

- Primary Outcome Measures
Name Time Method progression free survival up to end of follow-up-phase (approximately 3 years) time from the date of enrollment to date of disease progression, or death of any cause, or date of lost follow-up, whichever comes first
- Secondary Outcome Measures
Name Time Method overall survival up to end of follow-up-phase (approximately 3 years) overall survival (OS): time from the date of enrollment to date of death from any cause, or date of lost follow-up, whichever comes first
safety, as measured by adverse events up to end of follow-up-phase (approximately 3 years) ncluding hematological safety and non-hematological safety.All the adverse events will be classified according to Common Terminology Criteria for Adverse Events v3.0 (CTCAE)
complete remission rate every 4 weeks,up to completion of treatment(approximately 6 months) The criteria for the efficacy evaluation (overall response rate and complete remission) of the regimen is according to the following article:
