Double-blind, placebo-controlled pilot study of processed ultra emu oil versus placebo in the prevention of radiation dermatitis.

To evaluate the effects of an oil-based skin agent, Ultra Emu Oil, on skin-related toxicity in patients undergoing radiation therapy (RT) to the breast or chest wall
Patients were randomized to receive either the emu oil or a cotton seed oil placebo. Patients were instructed to apply the oil two times per day during radiation treatment and for six weeks after completion. The oil was to be applied at least four hours before treatment to avoid any bolus effect. No other creams or oils were to be used. Any additional treatments were to be documented by providers. Patients were assessed at baseline, weekly during treatment, and six weeks later.
PHASE OF CARE: Active antitumor treatment
Patient symptoms reported varied between groups, with some symptoms more severe in the emu oil group and some more severe in the control group. No statistically significant differences in symptoms or skin toxicity scores existed between groups. For most of the study period, those using the emu oil had lower Skindex scores; however, by the end of the trial, their Skindex scores were higher. A higher proportion of those using emu oil had grade 2 and 3 CTCAE scores, although this difference was not statistically significant.
This study did not show any substantial benefit or adverse effects associated with the use of emu oil to prevent radiodermatitis.
Radiation dermatitis is a common dermatologic adverse event, and management of this toxicity requires a wide range of treatment modalities. This study did not provide strong evidence for or against the use of emu oil. Further research is needed to determine efficacy and safety.
