A Prospective, Randomized, Multicenter Clinical Study Comparing Adjuvant Radiotherapy Versus Observation in High-risk Localized Adrenocortical Carcinoma After Surgery.

This study is a prospective, randomized, controlled, multicenter clinical trial designed to evaluate whether adjuvant radiotherapy can improve the 3-year recurrence-free survival (RFS) in high-risk localized adrenocortical carcinoma (ACC) patients after radical resection. According to the inclusion and exclusion criteria of the study protocol, 58patients with high-risk localized ACC who underwent radical resection were enrolled and randomly divided into two groups: the control group (Group A), which received regular postoperative follow-up without intervention, and the study group (Group B), which received adjuvant radiotherapy after surgery. The study compared the 3-year RFS and 3-year overall survival (OS) between the two groups and assessed the incidence of grade 3/4 radiotherapy-related adverse reactions, aiming to further clarify the efficacy and safety of postoperative adjuvant radiotherapy.
