The Topical Application of Vitamin B6 in Palmar-Plantar Erythrodysesthesia

This will be a randomized double-blind, placebo-controlled study with 100 cancer patients that will receive chemotherapy treatment with capecitabine and/or pegylated liposomal doxorubicin. The selection of potential participants will be based on inclusion and exclusion criteria. Patients will be randomly allocated either to the treatment group or the placebo group. Treatment will be delivered daily (t.d.s) and assessments will take place at 0, 1, 2, 3 and 4 weeks.

The intervention group will receive the application of topical vitamin B6 cream to the hands and/or feet of the patients and the control group will receive the placebo.

At both baseline and follow-up, patients in both groups will be assessed for their degree of palmar-plantar erythrodysesthesia, the Quality of Life, the need for dose-limiting due to PPE and Pain intensity using standardized rating scales. Data will be analysed with inferential and descriptive statistics.
