Adenosarcomas
STAGE I

More than half myometrial invasion

Carcinosarcomas
Carcinosarcomas should be staged as carcinomas of the endometrium.
*Note:
Simultaneous endometrial stromal sarcomas of the uterine corpus and ovary/pelvis in association with ovarian/pelvic endometriosis should be classified as independent primary tumors.
