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 I: tumor confined to the corpus uteri
- Stage IA: no or less than half myometrial invasion
- Stage 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
- Stage IIIA: tumor invades the serosa of the corpus uteri and/or adnexae
- Stage IIIB: vaginal involvement and/or parametrial involvement
- Stage IIIC: metastases to pelvic and/or para-aortic lymph nodes
- Stage IIIC1: positive pelvic nodes
- Stage IIIC2: positive para-aortic nodes with or without positive pelvic lymph nodes
- Stage IV: tumor invades bladder and/or bowel mucosa, and/or distant metastases
- Stage IVA: tumor invasion of bladder and/or bowel mucosa
- Stage IVB: distant metastasis, including intra-abdominal metastases and/or inguinal nodes
| 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 invades any of the following: |
| (i) upper urethral and/or vaginal mucosa, bladder mucosa, rectal mucosa, or fixed to pelvic bone, or | |
| (ii) fixed or ulcerated inguinofemoral lymph nodes. | |
| IVB | Any distant metastasis including pelvic lymph nodes. |
