According to the revised FIGO 2018 staging for cervical carcinoma, a tumour involving the lower third of the vagina without extending to the pelvic wall, with lymph node metastasis confirmed on imaging, is classified as:
- A Stage IIIA
- B Stage IIIB
- C Stage IIIC1r ✓
- D Stage IIIC2r
Correct answer: C. Stage IIIC1r
Explanation
FIGO 2018 introduced Stage IIIC for pelvic (IIIC1) or para-aortic (IIIC2) lymph node metastases regardless of tumour size. The suffix 'r' denotes imaging-based diagnosis and 'p' denotes pathological confirmation. Stage IIIA refers to lower third vaginal involvement without nodal disease; IIIB refers to pelvic wall extension or hydronephrosis. Here, lower third vaginal involvement alone would be IIIA, but confirmed pelvic nodal metastasis on imaging upgrades it to IIIC1r.
