Overview

Chondrosarcoma is staged based on enniking staging system for malignant bone tumor based on histological and radiological findings.

Staging

  • Chondrosarcoma is staged based on enniking staging system.

Enneking (MSTS) Staging System

  • The Enneking surgical staging system (also known as the MSTS system) for malignant musculoskeletal tumors based on radiographic characteristics of the tumor host margin.[1][2]
  • It is widely accepted and routinely used staging system.
Stages Grade Site Metastasis
IA G1: Low grade T1: Intracompartmental M0: No metastasis
IB G1: Low grade T2: Extracompartmental M0: No metastasis
IIA G2: High grade T1: Intracompartmental M0: No metastasis
IIB G2: High grade T2: Extracompartmental M0: No metastasis
III G1 or G2 T1 or T2 M1: Regional or distant metastasis
