Survivin as prognostic and predictive factor in patients treated with gemcitabine, dexamethasone, and cisplatin for relapsed or refractory aggressive NHL.

Abstract

The prognosis of relapsed or refractory aggressive non-Hodgkin's lymphoma (NHL) after front-line therapy remains poor. The development of more effective and less toxic salvage regimens remains a major challenge. Survivin is a member of the family of inhibitors of apoptosis, and survivin was associated with short survival and bad prognosis. This study was to evaluate the efficacy of GDP regimen (gemcitabine, dexamethasone and cisplatin) on relapsed or refractory aggressive NHL and various prognostic factors with special emphasis on survivin and observe the . Forty-six patients with relapsed and refractory NHL, intermediate or high-grade NHL (Revised European American Lymphoma Classification), who at least one regimen were enrolled into this study, which was carried out at Department, , Tanta University from July 2012 to July 2014. The patients were treated with GDP regimen (gemcitabine 1,000 mg/m(2) on days one and eight, dexamethasone 40 mg on days 1-3, and cisplatin 25 mg/m(2) on days 1-3) every 3 weeks. The efficacy and adverse events were evaluated according to the WHO criteria. All patients were assessed for efficacy and toxicity. The overall response rate was 58.7 %. Fourteen patients showed a complete response, thirteen partial responses, twelve stable diseases, and seven progressive disease. The 24-month overall survival was 50.8 %. Survivin is associated with low overall response and shorter overall survival. Grade 3 anemia was observed in four patients, grade 3 leucopenia in six patients, grade 3 neutropenia in six patients, and grade 3 thrombocytopenia in four patients. Non-hematologic toxicity included grade 3 infection in four patients. The present schedule of GDP showed modest efficacy and mild toxicity in patients with relapsed or refractory aggressive NHL.
