According to FIGO 2023 revised staging of endometrial cancer, which of the following is correctly classified as Stage IIIC2?
- A Extension to pelvic lymph nodes only
- B Invasion of the bladder mucosa
- C Metastasis to para-aortic lymph nodes with or without pelvic node involvement ✓
- D Peritoneal cytology positive without other spread
Correct answer: C. Metastasis to para-aortic lymph nodes with or without pelvic node involvement
Explanation
FIGO 2023 endometrial cancer staging classifies: Stage IIIC1 as pelvic lymph node metastasis (without para-aortic involvement), and Stage IIIC2 as para-aortic node metastasis (irrespective of pelvic node status). Bladder mucosal invasion is Stage IVA. Positive peritoneal cytology alone does not upstage (FIGO 2009 revision removed this, and FIGO 2023 continues this approach). The 2023 update also incorporated molecular sub-types (POLE-ultramutated, MMR-deficient, p53-mutant, NSMP) into staging for the first time.
