A 56-year-old woman undergoes staging surgery for endometrioid adenocarcinoma. Histology shows tumour replacing endocervical glands with no invasion into the underlying cervical stroma. According to the FIGO 2009 staging system, what is her stage?
- A Stage I ✓
- B Stage IIA
- C Stage IIB
- D Stage IIIA
Correct answer: A. Stage I
Explanation
In FIGO 2009, cervical involvement qualifies as stage II only when there is cervical stromal invasion. Tumour confined to the uterus, including extension that merely replaces endocervical glandular epithelium without stromal invasion, is staged as stage I. The old FIGO 1988 category IIA (glandular involvement alone) was abolished precisely because these patients have outcomes identical to stage I disease. This change is a favourite examination point.
