Purpose: Taxane-containing induction chemotherapy (IC) regimens in combination with concurrent chemoradiotherapy (CCRT) have been compared with non-taxane-containing IC combined with CCRT in randomized controlled trials (RCTs) in Chinese patients with advanced nasopharyngeal carcinoma (NPC). This meta-analysis aimed to systematically evaluate their clinical efficacy and safety profiling in this ethnic population. @@@ Methods: The electronic databases, PubMed, Embase, MEDLINE, and Chinese Biomedical Database, were searched for eligible studies. The outcomes included overall response rate (ORR), 1-year survival rate, and different types of adverse events. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the strength of the associations. @@@ Results: A total of 12 RCTs (representing 835 patients) were identified. The pooled analysis showed that taxane-containing regimens had a significant improvement in ORR for nasopharyngeal lesion (OR = 4.57, 95% CI = 1.14-18.30, P= 0.032, z=2.15) but not in cervical lymph nodes (OR = 1.23, 95% CI = 0.65-2.36, P= 0.532, z=0.64) and in 1-year survival rates (OR = 1.19, 95% CI = 0.10-14.82, P=0.893, z=0.13) compared with non-taxane-containing regimens. Regarding the adverse events and toxicities, grade 3-4 leukopenia and neutropenia were significantly different between the two groups (P<0.001) in favor of the non-taxane-containing regimens, but grade 3-4 vomiting was significantly different between the two groups (P<0.005) in favor of the taxane-containing regimens. @@@ Conclusion: When combined with CCRT, taxane-containing IC regimens may be more efficient for short-term local control in Chinese patients with locally advanced NPC than the non-taxane-containing IC regimens. Moreover, the major toxic effects, which were bone marrow suppression, could be tolerated by majority of patients. More long-term follow-up and high-quality trials of NPC are needed to validate our findings.
