Under FIGO 2018 staging for cervical cancer, a patient has a 4 cm cervical tumor with parametrial invasion confirmed on MRI but not reaching the pelvic sidewall. Her lymph nodes show a 1.2 cm pelvic node on CT with FDG-PET avidity. What is her revised stage?
- A Stage IIB
- B Stage IIIC1 ✓
- C Stage IIIB
- D Stage IIIC2
Correct answer: B. Stage IIIC1
Explanation
FIGO 2018 introduced Stage IIIC for lymph node involvement regardless of tumor size or local extent: IIIC1 for pelvic node metastasis and IIIC2 for para-aortic node metastasis. This patient has parametrial invasion (which alone would be IIB) but also has pelvic lymph node metastasis confirmed by imaging, which upgrades her to Stage IIIC1. Stage IIIB is reserved for extension to the pelvic wall or ureteral obstruction without nodal involvement. IIIC2 requires para-aortic nodal disease.
