Interobserver agreement of the Tauli-pT1 classification in rectal pT1 adenocarcinoma.

ABSTRACT:

Purpose

In pT1 rectal adenocarcinoma, adverse pathological features guide the indication for radical surgery; however, they are present in only 10-15% of cases. Therefore, in most patients, accurate en bloc local excision with clear margins and precise submucosal invasion assessment is essential for appropriate risk stratification. Beyond absolute depth, a major challenge is the wide interindividual variability in submucosal thickness. The Taulí-pT1 classification, based on the measurement of healthy residual submucosa (hrSB) from the muscularis propria, has been proposed as an objective and reproducible system. This study aimed to validate this classification.

Method

An interobserver study was conducted on 30 patients with pT1 rectal adenocarcinoma treated by transanal endo
