Answer

NCCN recommendations for lymphadenectomy are as follows [93] :

  • Lymph nodes at the origin of feeding vessel should be identified for pathologic exam
  • Clinically positive lymph nodes outside the field of resection that are considered suspicious should be biopsied or removed, if possible
  • Positive nodes left behind indicate an incomplete (R2) resection
  • A minimum of 12 lymph nodes need to be examined to establish N stage
