Secondary Objectives: 1-year local progression-free survival (LPFS) and overall survival (OS), 2-year LPFS and OS, and side effects of the treatment.\n\nStudy Design: A single-arm, open-label, prospective phase II study. Study Population and Expected Enrollment: Patients with unresectable locally recurrent rectal adenocarcinoma, with an expected enrollment of 20 patients.\n\nScheduled Visits and Duration: December 2024 to November 2026. Trial Duration: December 2024 to November 2026. Intervention: SBRT for unresectable locally recurrent rectal cancer. Statistical Hypothesis: Enrolled patients are those with unresectable recurrent rectal cancer. Based on previous literature reports and retrospective clinical data from our center, it is hypothesized that the R0 resection rate for patients with unresectable locally recurrent colorectal cancer who do not receive SBRT is 20%, while the R0 resection rate for those receiving SBRT intervention is 50%.
