Skin toxicity with anti-EGFR monoclonal antibody in cancer patients: a meta-analysis of 65 randomized controlled trials.

We performed a meta-analysis to fully investigate the skin toxicities of anti-EGFR monoclonal antibody (EGFR-MoAbs) in cancer patients. The relevant studies of the randomized controlled trials (RCTs) in cancer patients treated with EGFR-MoAbs were retrieved and the systematic evaluation was conducted. EMBASE, MEDLINE, and PubMed were searched for articles published till November 2017. The relevant RCTs in cancer patients treated with EGFR-MoAbs were retrieved and the systematic evaluation was conducted. 65 RCTs and 25994 patients were included. The current meta-analysis suggests that the use of EGFR-MoAbs significantly increases the risk of developing all-grade and high-grade skin toxicity, such as rash, hand-foot syndrome, dry skin and oral mucositis. Rash was the most common skin toxicity. Patients receiving nimotuzumab were associated with the least risk of skin toxicity. The risk of high-grade skin toxicity tended to be higher in the study in which the EGFR-MoAbs treatment duration was longer. The available data suggested that the use of EGFR-MoAbs significantly increases the risk of developing skin toxicity. Physicians should be aware of skin toxicity and should monitor cancer patients when receiving EGFR-MoAbs.
