Example
- Enneking stage
- IIB - high-grade, extracompartmental, no mets
Result: Enneking stage IIB: high-grade (G2), extracompartmental (T2), no metastasis (M0).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Stage IA
- Low-grade (G1), intracompartmental (T1), no metastasis (M0).
- Stage IB
- Low-grade (G1), extracompartmental (T2), no metastasis (M0).
- Stage IIA
- High-grade (G2), intracompartmental (T1), no metastasis (M0).
- Stage IIB
- High-grade (G2), extracompartmental (T2), no metastasis (M0).
- Stage III
- Any regional or distant metastasis (M1), regardless of grade or compartment.
What you enter
- Enneking stage
