FIGO: International Federation of Gynecology and Obstetrics.
FIGO stageTumor criteria
ITumor confined to the corpus uteri, including endocervical glandular involvement
IATumor limited to the endometrium or invading less than half of the myometrium
IBTumor invading one half or more than half of the myometrium
IITumor invading the stromal connective tissue of the cervix but not extending beyond the uterus. Does not include endocervical glandular involvement
IIITumor involving serosa, adnexa, vagina, or parametrium
IIIATumor involving the serosa and/or adnexa (direct extension or metastasis)
IIIBVaginal involvement (direct extension or metastasis) or parametrial involvement
IVATumor invading the bladder mucosa and/or bowel mucosa

IIIC1Regional lymph node metastasis (greater than 2.0 mm in diameter) to pelvic lymph nodes
IIIC2Regional lymph node metastasis to para-aortic lymph nodes, with or without positive pelvic lymph nodes
