Uterine Sarcoma Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage Information for Uterine Sarcoma

Definitions: FIGO

The Féderation Internationale de Gynécologie et d'Obstétrique (FIGO) and the American Joint Committee on Cancer (AJCC) have designated staging to define carcinoma of the corpus uteri, which applies to uterine sarcoma; the FIGO system is most commonly used.[1,2]

Uterine sarcomas include leiomyosarcomas, endometrial stromal sarcomas, and adenosarcomas.
