Prophylactic use of Mepitel Film prevents radiation-induced moist desquamation in an intra-patient randomised controlled clinical trial of 78 breast cancer patients.

PURPOSE Safetac-based soft silicone dressings used in a management setting decrease the severity of radiation-induced acute skin reactions but do not affect moist desquamation rates. Here we investigate the prophylactic use of another Safetac product, Mepitel Film, on moist desquamation rates. MATERIAL AND METHODS A total of 80 breast cancer patients receiving radiation therapy were recruited between October 2012 and April 2013; 78 participants contributed data for analysis. Lateral and medial halves of the skin areas to be irradiated were randomised to Mepitel Film or aqueous cream; skin dose was measured using thermoluminescent dosimeters; skin reaction severity was assessed using RISRAS and RTOG scales. RESULTS Overall skin reaction severity was reduced by 92% (p<0.0001) in favour of Mepitel Film (RISRAS). All patients developed some form of reaction in cream-treated skin which progressed to moist desquamation in 26% of patients (RTOG grades I: 28%; IIA: 46%; IIB: 18%; III: 8%). Only 44% of patients had a skin reaction under the Film, which did not progress to moist desquamation in any of the patients (RTOG grades I: 36%; IIA: 8%). CONCLUSIONS Mepitel Film completely prevented moist desquamation and reduced skin reaction severity by 92% when used prophylactically in our cohort.
