Answer

Answer

Pathologic lymph node staging is as follows:

  • pNX - Regional nodes not sampled
  • pN0 - No positive regional nodes
  • pN1 - Metastases in regional node(s)

Regional lymph nodes are assessed via surgical removal or through biopsy of the pelvic lymph nodes, including the obturator chain. The surgical boundaries include the bifurcation of the common iliac, the obturator nerve, and the node of Cloquet.
