Stage Information for Uterine Sarcoma
The FIGO staging for carcinoma of the corpus uteri has been applied to uterine
sarcoma.[1]
Stage I
Stage I sarcoma is confined to the corpus uteri. This stage accounts for 50%
of all presentations.
- Stage IA: tumor limited to endometrium.
- Stage IB: invasion to less than 50% of the myometrium.
- Stage IC: invasion to more than 50% of the myometrium.
Stage II
Stage II uterine sarcoma means the cancer has involved the corpus and the
cervix but has not extended outside the uterus.
- Stage IIA: endocervical glandular involvement only.
- Stage IIB: cervical stromal invasion.
Stage III
Stage III uterine sarcoma means extension outside of the uterus but confined to
the true pelvis.
- Stage IIIA: tumor invades serosa and/or adnexae and/or positive peritoneal
cytology.
- Stage IIIB: metastases to pelvic and/or para-aortic lymph nodes.
Stage IV
Stage IV uterine sarcoma means involvement of the bladder or bowel mucosa or
metastasis to distant sites.
- Stage IVA: tumor invasion of bladder and/or bowel mucosa.
- Stage IVB: distant metastases, including intra-abdominal and/or inguinal
lymph nodes.
