In Regard to Cicchetti et al

To the Editor: We congratulate Cicchetti et al for their recent publication on the external validation of the model predicting late fecal incontinence (FI).1 This report represents one of the few studies to address FI after radiation therapy in prostate cancer. Less frequently reported than other toxicities, FI represents one of the most quality-of-life–impairing symptoms. This study aimed to validate a predictive model for late FI by Rancati et al.2
