Abstract

A chronological overview of the various staging systems for colorectal cancer is presented in an effort to demonstrate the reason for the current state of confusion. The Dukes 1932 system is considered to be the gold standard because of its simplicity and accuracy and is the system most often referred to in the literature. Number of positive nodes and depth of invasion are two variables that have been found to be predictors of survival. In the future, other prognostic factors such as nuclear morphology, flow cytometric characteristics, histological grade, and vascular or lymphatic invasion may also be entered into the staging equation. Use of the TNM system at this time is recommended since it most completely describes appropriate prognostic factors and allows conversion of other staging systems into a common format. Future modifications could logically evolve from the TNM system.
