Dermatitis During Adjuvant Irradiation for BREAst Cancer:

From the start of radiotherapy, standard skin care has to be performed by the patient. This may vary at the participating centers. At the site in Lübeck, it includes fatty cream with 2-10% urea (fatty cream alone, if patients do not tolerate urea) and, in case of pruritus, addition of mometasone furoate cream. In case of grade ≥2 moist desquamation or grade ≥3 radiation dermatitis, each day antiseptic agents will be administered for wound cleansing followed by administration of silicon or calcium alginate bandage. This treatment will be continued until moist desquamation radiation disappears and radiation dermatitis improves to grade 2. Fatty cream with 2-10% urea is applied to the irradiated skin four times daily. Mometasone furoate cream: In addition to the fatty cream with 2-10% urea, mometasone furoate cream (solution 0.1%) is applied to the irradiated skin once daily.

In addition to standard skin care, patients are supported by a Reminder App. The purpose of the app is to remind the patients in an intuitive, unobtrusive and supportive way to perform skin care. By default, patients are reminded four times a day, but they will also be able to define a notification schedule that best suits their personal needs. The patients may postpone each required care procedure for up to 2 hours. With each procedure, the patients are guided through the skin care with simple and self-explanatory illustrations. To increase the patients' motivation, they will additionally earn points for regular and punctual performed care procedures. The patients receive a hand-out including instructions how to properly perform skin care, but they can also find an information page within the application that includes similar instructions.
