Effects of two medicines for prevention of acute radiation skin injury in radiation field among liver cancer patients with Cyberknife therapy

Abstract

Objective To explore the protective effect of DWK skin protectant and Sanyrene for prevention of acute radiation skin injury in radiation field among liver cancer patients with Cyberknife therapy. Methods A total of 100 liver cancer patients with Cyberknife therapy were selected by convenience sampling from March to November 2016. They were randomly divided into the group of DWK and the group of Sanyrene with 50 cases in each group. Skins in radiation field on hepatic region of patients in two groups used DWK skin protectant and Sanyrene respectively since one day before radiotherapy. The acute radiation skin injury of radiation field on hepatic region was observed from one day before treatment to two weeks the end of treatment during Cyberknife therapy. Results The scores of The Radiation Induced Skin Reaction Assessment Scale (RISRAS) , an instrument for assessing the degree of acute radiation skin injury of radiation field on hepatic region, of patients in two groups increased with the increasing cumulated dose of irradiation with significant differences (F=3.780, 12.325; P<0.05) . There were statistically significant differences in evaluations at the fifth and beyond between two groups (t=5.213, 12.437, 16.846; P<0.05) . Conclusions Intervention for local prevention can alleviate the acute radiation skin injury in radiation field on hepatic region among liver cancer patients with Cyberknife therapy. The protective effect of DWK skin protectant on skin in radiation field on hepatic region among liver cancer patients with Cyberknife therapy is better than that of Sanyrene.
