Adenosarcomas

STAGE I

IC
Tumor limited to uterus
Tumor limited to endometrium/endocervix with no myometrial invasion
Less than or equal to half myometrial invasion
More than half myometrial invasion
STAGE II
IIA
IIB
Tumor extends beyond the uterus, within the pelvis
Adnexal involvement
Involvement of other pelvic tissues
STAGE III
IIIA

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.
