Clinical N

This input is used for staging


**Note 1:** When both the Federation Internationale de Gynecologie et d'Obstetrique (FIGO) stage and regional lymph node detail are available, use the regional lymph node detail in preference to a statement of FIGO stage - see Registrar notes. * If the only information is FIGO III [NOS] or IIIC, assign the appropriate stage and leave clinical T, N, and M blank. If the only information is FIGO stage IV, leave T and N blank and see M **Note 2:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis). **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 (N0). * 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 Para-aortic Pelvic Subdiaphragmatic Iliac Common iliac External iliac Internal iliac (hypogastric): Obturator Inguinal Retroperitoneal, NOS
