FIGO Staging for Uterine Corpus Carcinoma

Description

In 1971 the International Federation of Gynecology and Obstetrics (FIGO) proposed a surgical staging system for carcinoma of the uterine corpus. This was later modified in 1988. In the event that a patient is treated with radiation therapy alone (without surgical resection), then the 1971 staging criteria may still be used but should be designated as such.

1988 Staging	Stage
limited to endometrium (in-situ)	IA
invasion less than one-half of myometrium	IB
invasion one half or more of the myometrium	IC
involvement of endocervical glands	IIA
invasion of cervical stroma	IIB
tumor invades uterine serosa, AND/OR adnexae, AND/OR positive uterine cytology	IIIA
metastases to vagina	IIIB
metastases to pelvic AND/OR para-aortic lymph nodes	IIIC
tumor invasion of bladder AND/OR bowel mucosa	IVA
distant metastases, included involvement of intra-abdominal OR inguinal lymph nodes	IVB

1971 Staging	Stage
limited to uterine corpus	I
length of uterine cavity <= 8 cm	IA
length of uterine cavity > 8 cm	IB
involvement of endocervix OR cervix	II
extends outside of uterus but not outside of the true pelvis	III
extends outside of true pelvis, OR involves the bladder, OR involves the rectum	IV

Guidelines:

(1) The thickness of the myometrium should be recorded along with the width of tumor invasion.

(2) Fractional D&C is no longer done to separate Stage I from Stage II unless the 1971 criteria are being used.
