Overview
According to the FIGO cancer staging system, there are 4 stages of endometrial cancer.
Staging
Endometrial carcinoma is surgically staged using the FIGO cancer staging system.[1]
| Stage | Findings |
|---|---|
| Stage I | Tumor confined to the corpus uteri |
| IA | No or less than half myometrial invasion |
| IB | Invasion equal to or more than half of the myometrium |
| Stage II | Tumor invades cervical stroma but does not extend beyond the uterus |
| Stage III | Local and/or regional spread of the tumor |
| IIIA | Tumor invades the serosa of the corpus uteri and/or adnexae |
| IIIB | Vaginal involvement and/or parametrial involvement |
| III C | Metastases to pelvic and/or para-aortic lymph nodes |
| (i) Positive pelvic nodes | |
| (ii) Positive para-aortic nodes with or without positive pelvic lymph nodes | |
| Stage IV | Tumor invades bladder and/or bowel mucosa, and/or distant metastases |
| IVA | Tumor invasion of bladder and/or bowel mucosa |
| IVB | Distant metastasis, including intra-abdominal metastases and/or inguinal nodes |
