Breast cancer patients report reduced sensitivity and pain using a barrier film during radiotherapy - A Danish intra-patient randomized multicentre study.

BACKGROUND AND PURPOSE: Radiodermatitis is a well-known toxicity of radiotherapy and barrier film has been shown to reduce the severity of radiodermatitis. We have validated prior findings in a Danish cohort, using a similar barrier film and patient reported outcomes.

MATERIALS AND

METHODS

101 Danish breast cancer patients were included at three radiotherapy centres. Based on randomization either the lateral or medial part of their chest was covered by Mepitel film; making the patients their own control. The primary endpoint was patient reported symptoms and experience. A secondary endpoint was radiotherapy staff evaluation of dermatitis.

RESULTS

Within the skin area covered by film, the patients reported a statistical significant lower level of pain (p < .001), itching (p = 0.005), burning sensation (p = 0.005) as well as edema (p = 0.017) and reduced sensitivity (p < .001). Most patients (76%) would have preferred film on the entire treatment area (p < 0.001) and Mepitel Film as a standard treatment option (84%) (p < 0.001). Patients treated after mastectomy had a significantly lower severity of radiation-induced dermatitis with film at the end of RT compared to standard care (p = 0.005). However, in the blinded staff evaluation, no significant differences were found at follow-up.

CONCLUSIONS

Patients reported reduced symptoms from the skin with Mepitel Film and the majority would have preferred film as a standard offer to cover their entire treatment area. Especially women treated after mastectomy had a significantly lower level of radiodermatitis and preferred the film over standard care.
