Analysis of risk factors related to acute radiation dermatitis in breast cancer patients during radiotherapy
Journal of cancer research and therapeutics(2022)
Abstract
Aims: To investigate the incidence and influencing factors of acute radiation dermatitis (ARD) induced by radiotherapy in postoperative patients with breast cancer. Methods and Materials: A retrospective analysis was conducted on 598 patients with breast cancer who received postoperative radiotherapy from November 18, 2014 to September 14, 2019. The radiotherapy technology included two-dimensional radiotherapy, three-dimensional conformal radiotherapy, intensity-modulated radiotherapy, and tomotherapy. The occurrence of ARD in patients was then followed up and recorded. The independent risk factors for radiation-induced dermatitis were analyzed by using an orderly logistic regression model. Results: Of the 598 patients, 431 had mild skin reactions, including pigmentation and dry desquamation (grade 1), 151 developed wet desquamation and tender erythema (grade 2), and 16 had severe skin reactions, including flaky wet scaling and erosion (grade 3). There were no grade 4 skin reactions. The severity of ARD was independent of the following factors: Age, diabetes, allergy, quadrant, pathological type, the clinical stage, the tumor stage, triple-negative breast cancer, ki-67 expression, adjuvant chemotherapy, endocrine therapy, targeted therapy, radiotherapy area, and boost irradiation. However, it was found to be dependent on the body mass index, surgery type, radiotherapy technique, node stage, and the prophylactic use of topical agents. Conclusions: ARD in response to postoperative radiotherapy in patients with breast cancer is common and mild. Clinicians and patients need to cultivate awareness of the potential risk factors involved and then intervene to alleviate skin reactions and improve the quality of life.
