In recent decades, the median size of nodal metastases has decreased, paralleling the decrease in primary tumor size. The median size of nodal metastases is now approximately 6 mm,1 and 70% to 80% of patients have negative nodes after surgical and pathologic nodal staging. A systematic approach to the evaluation of lymph nodes is needed today to reliably identify metastatic carcinoma.
