Enneking Staging (Bone/Sarcoma)
Clinical Context & Background
The Enneking Staging System (MSTS) is widely used for the surgical staging of bone and soft tissue sarcomas. It relies on Grade (G), Local Extent (T), and Metastasis (M) to determine the stage, which in turn dictates the surgical margin required (e.g., Intralesional, Marginal, Wide, Radical).
Formula Logic
Stage based on Grade (Low/High), Site (Intra/Extracompartmental), and Mets.Reference Data
| Stage | Definition | Surgical Margin Goal |
|---|---|---|
| IA | Low Grade, Intracompartmental | Wide Excision |
| IB | Low Grade, Extracompartmental | Wide Excision |
| IIA | High Grade, Intracompartmental | Wide / Radical Resection |
| IIB | High Grade, Extracompartmental | Radical Resection |
| III | Any Grade with Metastasis | Palliative / Resection of Mets |
