ObjectivesThe efficacy of various chemotherapy regimens in nasopharyngeal carcinoma (NPC) remains under debate. We compared the efficacy and toxicity of a taxane-based regimen and regimen including fluorouracil in NPC.Materials and methodsEight-hundred and six patients with stage II-IVB NPC from four institutions in China were pair-matched (1:1 ratio) to the cisplatin plus fluorouracil (PF) group or cisplatin plus taxanes (TP) group using eight clinical factors. Overall survival (OS), disease-free survival (DFS), locoregional relapse-free survival (LRRFS) and distant metastasis-free survival (DMFS) were assessed using the Kaplan-Meier method and Cox regression model. Toxicities were assessed in all patients.ResultsThree-year DFS was significantly better in the TP group than PF group (82.5% vs. 72.7%, P=0.002), with no significant difference in OS, LRRFS or DMFS. TP led to significantly better DFS compared to PF in the subgroups advanced stage NPC, patients aged ≤45-years-old and female patients. In multivariate analysis, chemotherapy regimen was an independent prognostic factor for DFS [hazard ratio, 0.591, 95% CI 0.444–0.786, P=0.000]. Grade 3–4 leukopenia, neutropenia and anemia were significantly more common in the TP group; grade 3–4 mucositis, vomiting, vasculitis and diarrhea were more common in the PF group.ConclusionTaxane-based regimens have a higher efficacy in NPC than regimens including fluorouracil, especially in patients with advanced stage, patients aged≤45-years-old and female patients.
