ABSTRACT
Objective:To evaluate the efficacy and safety of pegaspargase plus GEMOX (pegaspargase, gemcitabine, oxaliplatin) regimen in the initial treatment of nasal NK/T-cell lymphoma. Methods: Twelve preliminarily diagnosed nasal NK/T-cell lymphoma patients in Tianjin Medical University Cancer Institute and Hospital from June 2011 to March 2012 were analyzed. All patients took the pegaspargase plus GEMOX regimen (gemcitabine 800-1 000 mg/m2 on days 1 and 8, oxaliplatin 130 mg/m2 on day 1, and pegaspargase 2 500 IU/m2 on day 2), every three weeks for one cycle. The efficacy and toxicity of the regimen were evaluated in the follow-up treat-ment. Results:After two cycle treatments, 1 patient dropped out of treatment because of acute pancreatitis;the remaining 11 patients had response, in which 1 achieved complete response , 7 had partial response, 2 had stable disease, and 1 had progressive disease. The objective response rate was 72.7%, and the disease control rate was 90.9%. The 2-year overall survival rate was 90.9%. With median 6-cycle P-GEMOX regimen treatment, 81.8% of 11 patients presented side effects, primarily myelosuppression and hepatic dysfunc-tion. Conclusion:Pegaspargase plus GEMOX regimen showed high efficacy on the initial treatment of nasal NK/T-cell lymphoma pa-tients, but the incidence of adverse effect was still high.
ABSTRACT
Bendamustine is a kind of nitrogen mustard derivatives consisting of a 2-chloroethylamine alkylating group and a benzimidazole ring.This special structure grants its anti-cancer mechanism different from other common alkylating agents with double function.Since approved,bendanustine has been widely used to treat henatologic malignancies and solid tumors such as breast cancer.In 2008,the FDA approved bendamustine injection for the treatment of chronic lymphocytic leukemia and indolent B cell non-Hodgkin's lymphoma.In recent years,scholars in China and abroad have carried out a series of clinical researches on single bendamustine and bendamsutine combinational chemotherapy,especially in hematologic malignancies,which obtained certain clinical efficacy.In this paper,the pharmacological actions,pharmacokinetics and clinical progress of bendamustine in lymphoma and leukemia are reviewed.
