About this study

Radiotherapy (RT) is common in the treatment of breast cancer, however, 95% of breast cancer patients are at risk of developing acute and chronic skin toxicities known as radiation dermatitis (RD) which includes symptoms such as pruritus, edema, erythema, and moist desquamation (MD). Patients with a larger breast size are especially at risk of developing RD. The severity of RD can impact patient's quality of life (QOL) and their ability to complete treatment. Skin care guidelines for patients receiving RT vary and include barrier films and dressings, antibiotics, topical corticosteroids, and moisturizers. A study conducted at the Sunnybrook Odette Cancer Centre investigated the effectiveness of the prone treatment position during RT compared to the supine position. The results indicated that the prone position reduced the incidence of MD from 39.6% in supine to 26.9% in prone. However, 1 in 4 patients in the prone position still develop MD. Another study conducted at Sunnybrook Odette Cancer Centre found that Mepitel Film (MF), a barrier film, is more effective than the standard of care in preventing grade 2 or 3 RD, reducing the incidence of grade 2 or 3 RD from 45% to 15%. Despite its effectiveness, MF cannot be used for patients in the prone position and is costly. The topical corticosteroid betamethasone can prevent skin toxicity through its anti-inflammatory properties and is absorbed by the skin with minimal side effects. Betamethasone is cost-efficient and studies have…
