Study on Different Types and Outcomes of Radiation Rectal Injury in Adults Aged 18 to 80

What this Trial Is About

This research aims to explore the relationship between different clinical types of radiation-induced rectal injury and patient outcomes. It is a prospective, observational study involving 150 patients diagnosed with chronic radiation proctitis, planned to start in December 2025. The study is designed to address gaps in knowledge and help improve diagnosis and treatment for patients with radiation rectal injury. Participants will not receive any specific treatment as part of the study. Instead, researchers will collect clinical data, results from intestinal endoscopy, imaging, pathology tests, and follow-up information over the study period. No interventions or changes to usual care will be made by the study team. Throughout the study, patients will be monitored for clinical outcomes related to radiation rectal injury over six months. Researchers will assess how clinical classifications relate to these outcomes and evaluate the accuracy of endoscopic and imaging methods for subtyping the condition. The study will provide valuable information to guide future care for affected patients and will conclude by the end of 2026.
