| Study Success | 8 months | This is a data collection study. Study success is considered when the interpathology agreement is improved when compared to the agreement identified in Elmore et al. \[5\]. \[(classes/agreement): class I (eg, nevus or mild atypia) / 92% (95% confidence interval 90% to 94); class II (eg, moderate atypia) / 25% (22% to 28%); III (eg, severe atypia or melanoma in situ) / 40% (37% to 44%); IV (eg, pathologic stage T1a (pT1a) early invasive melanoma) / 43% (39% to 46%); and V (eg, ≥pT1b invasive melanoma) / 72% (69% to 75%).\] |
