Association Between Clinical Classification and Prognosis in Chronic Radiation Enteropathy

This is a prospective, observational study aimed at exploring the associations between the clinical classification of chronic radiation enteropathy and prognosis. The study is planed to commence in November 2025 and prospectively observe 150 patients. During the study period, researchers will not intervene in clinical treatment decisions but will only collect patient clinical information, intestinal endoscopy/imaging/pathological data, test results, and follow-up data. The study results will fill the evidence gap in this field, advance the diagnosis and treatment of chronic radiation enteropathy, and provide scientific support for improving the prognosis of similar patients.

Treatment and study plan

Primary outcomes

  1. Association between Clinical Classification and Clinical Outcomes

    Time frame: 6 months

    To investigate the association between clinical classification and outcomes, the primary outcome was assessed as complete remission of their primary symptom, while the measure was identified as the remission rate.

Secondary outcomes

  1. Predictive Accuracy of Endoscopic Characteristics for Clinical Classification

    Time frame: 6 months

    Using prospectively collected endoscopic data, the investigators will assess the association between specific endoscopic features and the data-driven clinical classification. The predictive accuracy will be quantitatively measured using metrics including sensitivity and specificity. The results aim to determine whether endoscopic findings can serve as reliable indicators for subtype identification.

  2. Predictive Accuracy of Imaging Evaluation for Clinical Classification

    Time frame: 6 months

    Using prospectively collected endoscopic data, the investigators will assess the association between features of MRI/CT and the data-driven clinical classification. The predictive accuracy will be quantitatively measured using metrics including sensitivity and specificity. The results aim to determine whether endoscopic findings can serve as reliable indicators for subtype identification.
