Collaborative Stage

Note 1: Assign code 000 if either there is no lymph node involvement (CS Lymph Nodes is coded 000) or there are in-transit metastases or satellite nodules, but no regional lymph node involvement (CS Lymph Nodes is coded 130, 140, 150, or 154).
Note 2: Assign code 000 if there are clinically apparent lymph node metastases but they are pathologically negative.
Note 3: AJCC defines microscopic lymph node metastases or "micrometastases" as those which are clinically inapparent by palpation and/or imaging but are pathologically positive. Therefore, assign code 010 if lymph nodes are negative on palpation and/or imaging but are positive on pathology.
Note 4: Assign code 010 if there is microscopic confirmation of lymph node metastases but there is no documentation of the clinical status.
Note 5: Assign code 020 if there are clinically apparent lymph node metastases whether they are confirmed by pathology or pathology is not performed.
