An Evaluation of 2537 Gastrointestinal Stromal Tumors for a Proposed Clinical Staging System

Abstract

A staging system for GISTs that provides valuable prognostic information was developed. Further work to refine this system and validate it with other data sets should be undertaken. Mitotic index and standardized reporting may provide additional prognostic information and should be recorded for all tumors so that the most accurate staging system can be created.
