AbstractThe aim of this study was to investigate the effect of postoperative electron radiotherapy (RT) on local control for keloids and to identify risk factors for recurrence. The clinical data of 82 patients treated at our institution from January 2015 to October 2019 were collected. The data included the general condition of the patients, clinical characteristics of the keloids, treatment plan, local control, and treatment side effects. A total of 82 patients (129 keloids) were included. The study included 23 men (28%) and 59 females (72%). The median patient age was 32 years (range, 18-67 years). Twenty-six recurrences were observed, and the 1-, 3-, and 5-year local control rates were 93%, 81%, and 73%, respectively. Univariate analysis revealed that age (P = .03), hypertension (P = .04), scar shape (P < .001), primary site (P = .02), maximum lesion diameter (P < .001), pain and itching (P = .005), local tension (P = .005), and infection (P < .001) were risk factors for local recurrence. Multivariable analysis revealed that maximum lesion diameter (P < .001), infection (P < .001), interval between surgery and RT (P = .02), and previous treatment (P = .02) were independent risk factors. Complete excision of keloids combined with electron RT is safe and seemingly effective. For keloids with a high risk of recurrence, more aggressive treatment should be chosen, and further prospective studies are needed to explore the optimal treatment.Copyright © 2023 the Author(s).
