"notes" : "**Note 1:** Histological examination of a regional lymphadenectomy specimen will ordinarily include 12 or more lymph nodes. If the lymph nodes are negative, but the number ordinarily examined is not met, classify as pN0. (1)\n\n**Note 2:** Code only regional nodes and nodes, NOS in this field. Note 3 specifies when to code certain tumor deposits (TD) here. Distant nodes are coded in M (distant metastasis).\n\n**Note 3:** Per UICC, \"Tumor deposits (satellites), i.e., macroscopic or microscopic nests or nodules, in the pericolorectal adipose tissue's lymph drainage area of a primary carcinoma without histological evidence of residual lymph node in the nodule, may represent discontinuous spread, venous invasion with extravascular spread (V1/2) or a totally replaced lymph node (N1/2). If such deposits are observed with lesions that would otherwise be classified as T1 or T2, then the T classification is not changed, but the nodule(s) is recorded as N1c. If a nodule is documented by the pathologist to be a totally replaced lymph node (generally having a smooth contour), it should be recorded as a positive lymph node and not as a satellite, and each nodule should be counted separately as a lymph node in the final pN determination.\" (2)\n\n**Note 4:** Assign N1 if regional lymph nodes are involved but there is no indication of the number of nodes involved.\n\n**Regional lymph nodes**\n \n**All colon sites** \n\n Colic [NOS] \n Epicolic (adjacent to bowel wall) \n Mesocolic [NOS] \n Mesenteric [NOS]\n Paracolic/pericolic\n\n Lymph nodes, NOS\n Regional lymph nodes, NOS\n\n**Cecum (C180)** \n\n Anterior (prececal) \n Cecal [NOS]\n Ileocolic\n Periappendiceal\n Posterior (retrocecal)\n Right colic \n\n**Ascending colon (C182)** \n\n Ileocolic\n Middle colic\n Right colic\n\n**Hepatic flexure (C183)** \n\n Middle colic \n Right colic\n\n**Transverse colon (C184)** \n\n Inferior mesenteric \n Left colic \n Middle colic \n Right colic\n\n**Splenic flexure (C185)** \n\n Inferior mesenteric \n Left colic \n Middle colic\n\n**Descending colon (C186)** \n\n Inferior mesenteric \n Left colic \n Sigmoid \n\n**Sigmoid colon (C187)** \n\n Inferior mesenteric \n Left colic \n Rectosigmoid \n Sigmoid \n Sigmoidal (sigmoid mesenteric) \n Superior hemorrhoidal (hemorrhoidal)\n Superior rectal",
