What this trial studies

This interventional study enrolls adults with histologically confirmed rectal cancer who develop grade 2 or higher acute radiation dermatitis of the anal canal after radiotherapy. Eligible participants will receive either Mepilex Lite dressings applied to the affected anal canal area or the control approach (standard local care), with pain, skin healing, and ability to complete radiotherapy tracked over the treatment period. Mepilex Lite is a foam dressing designed to absorb exudate, keep the wound moist, and reduce pain. Safety, symptom scores, and wound healing endpoints will be recorded at planned follow-up visits at the hospital site.

Who should consider this trial

Good fit: Adults (≥18) with confirmed rectal cancer who are undergoing radiotherapy for the first time and develop grade 2 or higher acute radiation dermatitis of the anal canal and can give informed consent.

Not a fit: Patients with known allergies to dressing materials, serious comorbidities, ECOG performance status >3, those who withdraw or interrupt radiotherapy, or with uncontrolled anal fissures may not receive benefit from the dressing intervention.

Why it matters

Potential benefit: If successful, patients could have less anal pain, faster healing of radiation-induced skin injury, and a better chance of completing their planned radiotherapy.

How similar studies have performed: Foam dressings such as Mepilex have shown benefit for radiation dermatitis at other body sites in prior work, but their application inside the anal canal is less well studied.
