Keloids are a kind of fibrous hyperplastic skin condition primarily characterized by a high recurrence rate， presenting certain challenges in treatment. Among the various therapeutic approaches， adjuvant radiotherapy stands out as one of the crucial measures for preventing the recurrence of keloids. However， there is currently no clear consensus regarding the optimal dosage， fractionation method， and treatment intervals for radiotherapy， and its side effects and safety profile require further research and evaluation. With the continuous advancement of medical technology and treatment concepts， new therapeutic strategies are emerging. To promote the standardized application of adjuvant radiotherapy in the treatment of keloids， a consensus drafting group composed of experts from multiple fields， including plastic surgery， dermatology， and radiotherapy， organized by the China Association for Promotion of Health and Technology， has developed this consensus based on the principles of evidence-based medicine. The group referred to existing literature and treatment guidelines and engaged in multiple in-depth discussions to form the consensus. It elaborates on the mechanisms of action， indications， treatment parameters， contraindications， and considerations of adjuvant radiotherapy for keloids， aiming to provide a set of standardized recommendations for clinical keloid treatment.
