OBG · Gynaecological oncology: ASCUS with HPV triage
Sample itemA 35-year-old woman has a Pap smear reported as atypical squamous cells of undetermined significance. Reflex high-risk HPV testing is positive. What is the next step?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
C. Colposcopy with directed biopsy
In ASCUS, reflex HPV testing triages women. A positive high-risk HPV result means the risk of underlying CIN is significant, so the woman is referred for colposcopy. An HPV-negative result allows a return to routine screening.
Option by option
A. Reassurance and routine screening in 5 years
Routine screening is appropriate only after an HPV-negative result.
B. Repeat cytology in 12 months
Waiting 12 months is for women who are HPV negative or in specific triage pathways, not for HPV-positive women.
C. Colposcopy with directed biopsy (correct)
Correct. High-risk HPV positivity with ASCUS requires colposcopic assessment.
D. Hysterectomy
Hysterectomy is a gross over-treatment for an unconfirmed low-grade abnormality.
