The Féderation Internationale de Gynécologie et d'Obstétrique (FIGO) and the American Joint Committee on Cancer (AJCC) have designated staging to define endometrial cancer; the FIGO system is most commonly used.[1,2]
Carcinosarcomas should be staged as carcinoma. FIGO stages are further subdivided by the histologic grade of the tumor, for example, stage IC G2.

a Adapted from FIGO Committee on Gynecologic Oncology.
b Either G1, G2, or G3 (G = grade).
c Endocervical glandular involvement only should be considered as stage I and no longer as stage II.
d Positive cytology has to be reported separately without changing the stage.
Tumor confined to the corpus uteri.
No or less than half myometrial invasion.
Invasion equal to or more than half of the myometrium.
