A 48-year-old woman is found to have squamous cell carcinoma of the cervix invading the lower third of the vagina with no parametrial involvement and no hydronephrosis. According to FIGO 2018 cervical cancer staging, this is classified as:
- A Stage IIB
- B Stage IIA2
- C Stage IIIA ✓
- D Stage IIIB
Correct answer: C. Stage IIIA
Explanation
FIGO 2018 Stage IIIA is defined as involvement of the lower third of the vagina with no extension to the pelvic wall. Stage IIB is parametrial involvement not reaching the pelvic wall. Stage IIIB is extension to the pelvic wall and/or hydronephrosis/non-functioning kidney. Stage IIA2 is vaginal involvement (upper two-thirds) with tumour > 4 cm. Here, lower-third vaginal involvement without parametrial spread correctly classifies as Stage IIIA.
