A 62-year-old woman undergoes total hysterectomy for endometrial carcinoma. Final pathology shows grade 2 endometrioid adenocarcinoma invading the outer half of the myometrium, with negative lymph nodes, but positive peritoneal cytology. According to the 2023 FIGO staging system for endometrial carcinoma, what is her stage?
- A Stage IIIA
- B Does not affect the stage ✓
- C Stage IVB
- D Stage IIIC1
Correct answer: B. Does not affect the stage
Explanation
The 2023 FIGO staging system removed positive peritoneal cytology as a criterion for staging endometrial carcinoma. It is no longer classified as Stage IIIA or IVB. While it should still be noted in the pathology report, it does not change the formal FIGO stage. Stage IIIC1 requires positive pelvic lymph nodes, and Stage IVB requires distant metastases.
