The efficacy and safety of induction chemotherapy combined with concurrent chemoradiotherapy versus concurrent chemoradiotherapy alone in nasopharyngeal carcinoma patients: a systematic review and meta-analysis
Abstract Background Induction chemotherapy (IC) combined with concurrent chemoradiotherapy (CCRT) has been recommended as the first-line therapy for locoregional nasopharyngeal carcinoma (NPC). Due to the different chemotherapeutic drugs used in the IC and CCRT, the results remain controversial. Methods PubMed, EMBASE, Web of Science, and Cochrane Library databases were systematically retrieved to search potentially eligible clinical trials up to Sep 11, 2019. Eligible studies were registered and prospective randomized controlled clinical trials. Results From 526 records, nine articles including seven randomized controlled clinical trials were eligible, with a total of 2311 locoregional advanced NPC patients. IC + CCRT had significantly lower risks of death (3-year hazard ratio [HR]: 0.70, 95% confidence interval [CI] 0.55–0.89, p = 0.003; 5-year HR: 0.77, 95% CI 0.62–0.94, p = 0.01), disease progression (3-year HR: 0.67, 95% CI 0.55–0.80, p
