Is the Seventh Edition of the UICC/AJCC TNM Staging System Reasonable for Patients With Tumor Deposits in Colorectal Cancer?

Abstract

The seventh edition of TNM staging system on TDs satisfactorily predicts patients' outcome for those without LNM. Patients who categorized as T3N2bM0TD (+) and T4N2bM0TD (-/+) should be reclassified as stage IV. Number of TDs was not an independent prognostic parameter in the TNM staging system.
