A 55-year-old woman is diagnosed with cervical squamous cell carcinoma. Clinical examination reveals a 5 cm cervical tumor extending to the upper two-thirds of the vaginal wall. There is no parametrial invasion. MRI confirms these findings with no lymph node involvement. According to FIGO 2018 staging, what is the correct stage?
- A Stage IIA2 ✓
- B Stage IIA1
- C Stage IB2
- D Stage IIB
Correct answer: A. Stage IIA2
Explanation
According to FIGO 2018 staging, cervical carcinoma involving the upper two-thirds of the vagina without parametrial invasion is classified as Stage IIA. This stage is further subdivided by tumor size: Stage IIA1 for tumors measuring 4 cm or less, and Stage IIA2 for tumors exceeding 4 cm. Since this patient has a 5 cm tumor with vaginal involvement but no parametrial extension, she is Stage IIA2. Stage IB2 applies to tumors greater than 4 cm confined to the cervix, while Stage IIB requires parametrial invasion.
