Notes
**Note 1:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis). **Note 2:** Regional lymph nodes are defined as those in the vicinity of the primary tumor. **Note 3:** Regional lymph node involvement is rare. For this schema, if there is no mention of lymph node involvement clinically, assume that lymph nodes are negative. * Assign NX only when there is no available information on the extent of the patient's disease, for example when a lab-only case is abstracted from a biopsy report and no clinical history is available **Regional lymph nodes** Intra-abdominal Paracaval Pelvic SubdiaphragmaticNAACCR Item
