Staging
TNM Category FIGO Stage Primary Tumor (T)
TX   Primary tumor cannot be assessed
T0   No evidence of primary tumor
Tis   Carcinoma in situ (preinvasive carcinoma)
T1 I Tumor confined to corpus uteri
T1a IA Tumor limited to endometrium or invades less than one-half of the myometrium
T1b IB Tumor invades one-half or more of the myometrium
T2 II Tumor invades stromal connective tissue of the cervix but does not extend beyond uterus
T3a IIIA Tumor involves serosa and/or adnexa (direct extension or metastasis)
T3b IIIB Vaginal involvement (direct extension or metastasis) or parametrial involvement
T4 IVA Tumor invades bladder mucosa and/or bowel mucosa (bullous edema is not sufficient to classify a tumor as T4)

FIGO staging no longer includes stage 0 (Tis)

Endocervical glandular involvement only should be considered as stage I and not stage II

Staging
TNM Category FIGO Stage Regional Lymph Nodes (N)
NX   Regional lymph nodes cannot be assessed
N0   No regional lymph node metastasis
N1 IIIC1 Regional lymph node metastasis to pelvic lymph nodes
N2 IIIC2 Regional lymph node metastasis to para-aortic lymph nodes, with or without positive pelvic lymph nodes

Staging
TNM Category FIGO Stage Distant Metastasis (M)
M0   No distant metastasis (no pathologic M0; use clinical M to complete stage group)
MI IVB Distant metastasis (includes metastasis to inguinal lymph nodes intraperitoneal disease, or lung, liver, or bone. It excludes metastasis to paraaortic lymph nodes, vagina, pelvic serosa, or adnexa)
