Abstract BACKGROUND: Hand-foot syndrome (HFS) is a common cutaneous side effect of certain systemic chemotherapeutic agents. AIM: To assess the efficacy of pyridoxine supplements in the management of HFS. METHODS: We searched PubMed, EMBASE and the Cochrane Central Register of Controlled Trials for studies reporting the efficacy of pyridoxine supplements to manage HFS. We performed a meta-analysis using HFS incidence and improvement rates to measure the preventive and treatment efficacy of pyridoxine supplementation. RESULTS: We assessed eight studies [two retrospective studies, two prospective comparative trials and four randomized controlled trials (RCTs)] for preventive efficacy and three studies (one RCT and two non-RCTs) for treatment efficacy. A random-effects meta-analysis did not find any significant association between prophylactic pyridoxine supplementation and HFS development [relative risk (RR) = 0.95; 95\% CI 0.87-1.05) or any significant preventive efficacy against HFS in subgroup meta-analyses of study design, chemotherapeutic agents, pyridoxine dose, HFS severity, publication year or observation period. However, pyridoxine did show significant efficacy in treating HFS (RR = 1.75; 95\% CI 1.09-2.80), but did not show efficacy in the only RCT (RR = 1.12; 95\% CI 0.58-2.14). CONCLUSIONS: We found no clinical evidence to support the use of pyridoxine supplements to prevent HFS during chemotherapy. © 2014 British Association of Dermatologists.
