Note 2: Codes 600 - 750 are used for contiguous extension from the site of origin. Discontinuous involvement is coded in CS Mets at DX. Note 3: Tumor that is adherent to other organs or structures, macroscopically, is classified cT4b; If tumor is present in adhesion(s) upon microscopic examination, the tumor is classified as pT4b. Use code 565 for macroscopic adhesions if no pathologic confirmation, and for pathologically confirmed tumor in adhesions. However, if no tumor is present in adhesion(s) upon microscopic examination, the classification is based upon extent of tumor invasion into or through the wall; use codes 000 - 163, 200, 210, 400, 415, 455, 458, 500, and 555 as appropriate to describe the microscopically confirmed depth of tumor invasion for these cases. Use codes 610-800 to code invasion of underlying structures from the adherent tumor. Note 4: High grade dysplasia and severe dysplasia are generally not reportable in cancer registries but, if a registry does collect these, codes 000 or 050 should be used.

Note 2 specifies when to code tumor deposits (TD) here. Distant nodes are coded in CS Mets at DX. Note 2: One or more malignant satellite peritumoral nodules in the pericolorectal adipose tissue of a primary carcinoma without histologic evidence of residual lymph node in the nodule(s) may represent discontinuous spread, venous invasion with extravascular spread, or a totally replaced lymph node. If this is the only information on lymph nodes, use code 050. The total number of TD must always be coded in CS Site-Specific Factor 4. If there are TD and node involvement, code only the information on node involvement in this field; use a higher code number than 050. Note 3: Rectal nodes, NOS are coded 100. Middle or superior rectal nodes are coded 200 for both rectosigmoidal and rectal primaries. Inferior rectal nodes are coded 200 for rectal primaries. Inferior rectal nodes are coded in CS Mets at DX for rectosigmoidal primaries. Note 4: . Middle or superior hemorrhoidal nodes are coded 200 for both rectosigmoidal and rectal primaries. Inferior hemorrhoidal nodes are coded 200 for rectal primaries. Inferior hemorrhoidal nodes are coded in CS Mets at DX for rectosigmoidal primaries. Note 5: Mesenteric nodes, NOS are coded 300. Inferior mesenteric or sigmoid mesenteric nodes are coded 200. Superior mesenteric nodes are coded in CS Mets at DX. Note 6: CS does not collect information on otherwise negative lymph nodes containing isolated tumor cells (ITCs) for this schema. CS does not derive ITC status for this schema. Count otherwise negative regional nodes containing ITCs as negative nodes. Note 7: The number of positive regional nodes is required to calculate the correct N category for this schema. Use codes 400-480 when the pathology report assigns an N1 or N2 category but does not specify the number of nodes involved, or the record identifies an N1 or N2 category but the specific information about number of nodes involved is not available. Use codes 100-300 rather than codes 400-480 when information about the number of positive nodes is available, or when nodes are clinically positive but not removed for examination.
