(leiomyosarcomas, endometrial stromal sarcomas, adenosarcomas).
| Stage | Description | |
|---|---|---|
| Leiomyosarcomas and endometrial stromal sarcomas | ||
| I | Tumor limited to uterus | |
| IA | Less than 5 cm | |
| IB | More than 5 cm | |
| II | Tumor extends beyond the uterus, within the pelvis | |
| IIA | Adnexal involvement | |
| IIB | Involvement of other pelvic tissues | |
| III | Tumor invades abdominal tissues (not just protruding into the abdomen) | |
| IIIA | One site | |
| IIIB | More than one site | |
| IIIC | Metastasis to pelvic and/or para?aortic lymph nodes | |
| IV | ||
| IVA | Tumor invades bladder and/or rectum | |
| IVB | Distant metastasis | |
| Adenosarcomas | ||
| I | Tumor limited to uterus | |
| IA | Tumor limited to endometrium/endocervix with no myometrial invasion | |
| IB | Less than or equal to half myometrial invasion | |
| IC | More than half myometrial invasion | |
| II | Tumor extends to the pelvis | |
| IIA | Adnexal involvement | |
| IIB | Tumor extends to extrauterine pelvic tissue | |
| III | Tumor invades abdominal tissues (not just protruding into the abdomen) | |
| IIIA | One site | |
| IIIB | More than one site | |
| IIIC | Metastasis to pelvic and/or para-aortic lymph nodes | |
| IV | ||
| IVA | Tumor invades bladder and/or rectum | |
| IVB | Distant metastasis | |
| 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.
