Appendix

Note 1: Tumor deposits (TD) are defined as one or more satellite peritumoral nodules in the pericolorectal adipose tissue of a primary carcinoma without histologic evidence of residual lymph node in the nodule. Such TD may represent discontinuous spread, venous invasion with extravascular spread, or a totally replaced lymph node.
Note 2: Record the number of TD whether or not there are positive lymph nodes.
Note 3: Assign code 000 if surgical resection of the primary site is performed, the pathology report is available for review, and tumor deposits are not mentioned.
