Interrater reliability was substantial between radiologists for nodal (N) and overall staging (OS) (κ=0.715 and 0.715). Radiologist A review resulted in identical OS for 67% of patients, overstaging for 31%, and understaging for 2%. Radiologist B review resulted in 61% identical OS, 39% overstaging, and 0% understaging. In misclassified cases, the test of symmetry shows strong bias toward overstaging N stage and OS (P .001). Radiologic interpretation of extracapsular extension showed poor interrater reliability (κ=0.403)
