Analytical dosimetric study of postoperative brachytherapy and electron beam irradiation in the treatment of complex keloids

1. Abstract 1.1. Purpose: Keloid is a common benign skin tumor in the out- patient department. Pathogenesis is unknown, and single-meth- od treatment, such as surgery alone, has a high recurrence rate. Surgery followed by adjuvant radiotherapy is currently one of the most effective treatments for keloid. After long-term clinical prac- tice, brachytherapy and electron beam radiotherapy have become the gold standard methods of radiation delivery. This study aimed to compare the dosimetric impact and possible risks between these two techniques and to determine the preferred technique for treat- ment of complex keloids.
