Value of Rectal Ultrasound in Predicting Staging and Outcome in Patients With Rectal Adenocarcinoma

Abstract

In patients with rectal adenocarcinoma treated by preoperative radiotherapy, uT classification determined by transrectal ultrasonography before radiotherapy, pT and pN classification determined after radiotherapy, and tumor downstaging were predictors of survival contrary to uN. Only pTN classification, age, and gender were independent predictors in multivariate analysis.
