Beneficial effects of anti-EGFR agents, Cetuximab or Nimotuzumab, in combination with concurrent chemoradiotherapy in advanced nasopharyngeal carcinoma

The median follow-up was 57.0 months and 55.0 months for the CTX/NTZ plus CCRT group and IC plus CCRT group, respectively. No significant differences were found between the CTX/NTZ plus CCRT group and the IC plus CCRT group in 3-year OS (95.5% vs. 94.7%, P = 0.083), 3-year DFS (93.3% vs. 86.1%, P = 0.104), 3-year DMFS (96.2% vs. 92.5%, P = 0.243) and 3-year LRRFS (97.0% vs. 95.1%, P = 0.297). Patients undergoing IC plus CCRT suffered from severe hematologic toxicity and diarrhea compared with those treated with CTX/NTZ plus CCRT. The combination of CTX/NTZ with CCRT is comparable to IC plus CCRT treatment in survival outcomes for locoregionally advanced NPC patients but has a better safety profile than IC plus CCRT treatment.
