A systematic review and Meta-analysis on the association between Hand-Foot Syndrome (HFS) and Cancer Chemotherapy Efficacy.

Hand-foot syndrome (HFS) is a common skin toxicity of traditional chemotherapies. Some studies showed that HFS has an association with progression-free survival (PFS) and the overall survival (OS). So far, there is not available any systematic literature reviews or meta-analysis aimed to assess the associations between HFS, PFS and OS. For this reason, this study aims to quantitatively summarize, critically review, and interpret the recent literature related to the associations between HFS and efficacy of chemotherapy in terms of PFS and OS. Queries shaped by PICOM framework, a systematic search of three electronic databases (PubMed, Scopus, and Science Direct) was carried out for the period between January 2010 and December 2017. Quantitative data pooling was based on the calculation of Hazard Ratio (HR) with 95% Confidence Interval (95% CI) for the OS and PFS associated to the presence of HFS, through the data of original publications. Five papers were included in this systematic review for the quantitative data pooling. Patients with HFS showed improved PFS (HR = 0.532 [0.431-0.656]; p = 0.000) and improved OS (HR = 0.522 [0.427-0.638]; p = 0.000). HFS causes a reduction of compliance with oncology treatments. Healthcare providers should use this result as a trigger to foster patients' coping and the one of their family caregivers, enhancing their adherence to cancer treatments.
