Computed Tomography-Based High-Dose-Rate Intracavitary Brachytherapy for Uterine Cervical Cancer: Preliminary Demonstration of Correlation Between Dose-Volume Parameters and Rectal Mucosal Changes Observed by Flexible Sigmoidoscopy

Conclusion: Our preliminary data have shown that DVH values of the rectosigmoid colon obtained by computed tomography-based three-dimensional brachytherapy planning are reliable and predictive of score ≥2 rectosigmoid mucosal changes.
