Risk of hand-foot skin reaction associated with vascular endothelial growth factor–tyrosine kinase inhibitors: A meta-analysis of 57 randomized controlled trials involving 24,956 patients

Abstract

Multiple randomized controlled trials have assessed hand-foot skin reaction (HFSR) caused by vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs). We performed a meta-analysis to determine the incidence and the relative risk (RR) of HFSR associated with these agents. Databases were searched for relevant studies. Statistical analyses were conducted to calculate the summary incidences, RR, and 95% confidence intervals (CIs) by using random-effects or fixed-effects models according to the heterogeneity of the included studies. A total of 24,956 patients from 57 studies were included. The overall incidence of all-grade and high-grade HFSR associated with VEGFR-TKIs was 35.0% (95% CI, 28.6%-41.6%) and 9.7% (95% CI, 7.3%-12.3%), respectively. The use of VEGFR-TKIs significantly increased the risk of developing all-grade (RR, 5.09; 95% CI, 3.52-7.35; P<.001) and high-grade (RR, 9.42; 95% CI, 5.59-15.90; P<.001) HFSR. Subgroup analyses revealed that the risk of HFSR was significantly increased according to tumor type, VEGFR-TKI, trial phase, treatment regimen, and control therapy. No evidence of publication bias was observed. High heterogeneity in most studies. High risk of HFSR is prone to develop in cancer patients receiving VEGFR-TKIs.
