Cetuximab versus nimotuzumab for the treatment of advanced nasopharyngeal carcinoma: A network meta-analysis.

PURPOSE: We conducted a network meta-analysis to evaluate the efficacy and toxicity of cetuximab and nimotuzumab in the treatment of advanced nasopharyngeal carcinoma (NPC).

METHODS: A systematic literature search was performed though Pubmed, Embase, Cochran Library, China National Knowledge Infrastructure (CNKI), Chinese Biomedical (CBM) and Wanfang databases. Totally, 19 randomized controlled trials (RCTs) (n=1201) met the study selection criteria and were incorporated in this network meta-analysis.

RESULTS: Compared with cetuximab, the results of network meta-analysis indicated that nimotuzumab may achieve higher complete remission rate (CRR) or overall remission rate (ORR) of the primary tumor, but no difference was noticed in 1- and 2-year overall survival (OS) rate and certain toxicities such as myelosuppression, radiodermatitis, mucositis and gastrointestinal reactions. Although nimotuzumab increased the 3-year OS rate, compared with cetuximab, this result needs to be interpreted cautiously because of the studies' heterogeneity.

CONCLUSION: Even though we didn't find significant difference between cetuximab and nimotuzumab in terms of survival outcomes, nimotuzumab is more advantageous in short-term efficacy.
