title: Effectiveness of topical steroids in the control of radiation dermatitis: a randomised trial using 1% hydrocortisone cream and 0.05% clobetasone butyrate (Eumovate).
abstract: Radiation dermatitis often presents as a problem for patients and radiotherapists during treatment. Topical corticosteroids have been shown to have an anti-inflammatory effect in the treatment of many skin diseases and are commonly prescribed during a course of radiation treatment. A comparison of two different steroid creams, 1% hydrocortisone cream and 0.05% clobetasone butyrate (Eumovate), in a double blind trial was carried out in 54 patients undergoing radiation therapy for breast cancer. 'The cream' was administered when patients reached a given dose of 2000 rad (or earlier if required) whether a skin reaction was present or not. The aim of the trial was to evaluate the general effectiveness of steroids in controlling radiation dermatitis and whether one type of cream was superior to the other. The majority of patients using either cream derived benefit in its soothing effect. There was, however, a significant difference in the intensity of reactions seen, patients using clobetasone butyrate developed more severe radiation reactions despite both groups having similar radiation doses. The possibility of two differing populations having different responses to radiation is discussed as is the 'breakthrough phenomenon' described in the literature. It is concluded that neither cream should be used as first choice in the control of radiation dermatitis.
