A 47-year-old woman undergoes clinical assessment of a cervical squamous cell carcinoma. The tumour measures 3 cm, extends to involve the upper two-thirds of the vagina, and there is no parametrial soft tissue thickening on examination or MRI. What is the correct FIGO 2018 stage?
- A Stage IIB
- B Stage IIA2
- C Stage IIA1 ✓
- D Stage IIIA
Correct answer: C. Stage IIA1
Explanation
Involvement of the upper two-thirds of the vagina without parametrial extension places the tumour in Stage II. The 2018 revision subdivides Stage IIA by tumour size: IIA1 is less than 4 cm and IIA2 is 4 cm or greater. This 3 cm tumour is therefore IIA1. Stage IIIA would require lower-third vaginal involvement, and IIB requires parametrial invasion, both absent here.
