If the only information is (pathologic) FIGO stage IVB, leave pathologic T and N blank and see M\n\n**Note 2:** Histological examination of a pelvic lymphadenectomy specimen will ordinarily include 6 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 3:** Code only regional nodes and nodes, NOS, in this field. Distant nodes are coded in M (distant metastasis).\n\n**Note 4:** FIGO Stage IIIB is assigned based on primary tumor extension and/or regional lymph node involvement. \n* If it is unknown whether it is based on extension or regional lymph node involvement, assign clinical stage as 3B and leave clinical T, N, and M blank\n\n**Note 5:** If either exploratory or definitive surgery is done with no mention of lymph nodes, assume nodes are negative.\n\n**Note 6:** If the clinician says \"adnexa palpated\" but does not mention lymph nodes, assume lymph nodes are not involved.\n\n**Regional lymph nodes**\n\n Iliac, NOS\n Common\n External\n Internal (hypogastric)\n Obturator\n Paracervical\n Parametrial\n Pelvic, NOS\n Sacral, NOS\n Lateral (laterosacral)\n Middle (promontorial) (Gerota's node)\n Presacral\n Uterosacral\n\n Regional lymph nodes, NOS\n Lymph nodes, NOS",
