BackgroundIt is unclear whether cetuximab (CTX) plus cisplatin-based concurrent chemoradiotherapy (CCRT) delivers equivalent or improved results over standard CCRT in locoregionally advanced nasopharyngeal carcinoma (NPC).MethodsThe strategy involved searching the PubMed, Embase, Cochrane Library, and Web of Science. Pooled hazard ratios (HRs) for overall survival (OS), distant metastasis-free survival (DMFS), locoregional relapse-free survival (LRFS), and disease-free survival (DFS), and pooled risk ratios for adverse events were meta-analyzed.ResultsIn all, 1744 patients in 5 clinical trials were included in the analysis. Compared with CCRT group, CTX plus CCRT significantly improved DFS (HR = 0.59, 95% confidence interval [CI]: 0.41-0.86, P = .006) and distant metastasis failure-free survival (HR = 0.54, 95% CI: 0.38-0.76, P = .0004), rather than OS (HR = 0.70, 95% CI: 0.44-1.09, P = .12) and local-regional failure-free survival (HR = 0.82, 95% CI: 0.54-1.22, P = .33).ConclusionsCTX plus CCRT might achieve higher DFS and DMFS with no significant difference in OS and LRFS. CTX plus CCRT group was associated with more grade 3-4 skin rash, mucositis and dermatitis. Large randomized trials were urgent to fully explore the usefulness of this treatment in the locally advanced NPC patients.
