What was measured

Low Risk: T1-T2, N0-N1 AND clear (\> 3mm) margins, AND no extranodal extension (ENE) or PNI/LVI. Intermediate Risk: Any of the following features: one or more "close" (\< 3mm) margin(s), OR "Minimal" (\< 1mm) ENE, OR N2a (1 or more lymph node \>3cm in diameter), OR N2b (2-4 lymph nodes positive, any diameter \< 6cm), OR with perineural invastion or lymphovascular invasion. High Risk: Any of the following features: one or more positive margin(s) with any T stage, OR "Extensive" (\> 1mm) ENE, OR \> 5 metastatic lymph nodes (regardless of primary tumor margin status).
