EditorMoss et al show that colposcopy referral rates double if women with equivocal or mild cytological abnormality are referred for immediate colposcopy when human papillomavirus (HPV) is present in the first abnormal smear.1 Their colposcopy rates in women aged 35-64 seem to contradict those observed in the Netherlands.
We computed colposcopy referral rates in the Netherlands from data collected in the two armed POBASCAM screening trial.2 Women of 30-60 with borderline or mild dyskaryosis were recalled at 6 and 18 months and referred for colposcopy on the basis of repeat cytology according to current Dutch guidelines (control group) or on the basis of both repeat cytology and high risk HPV testing (intervention group).
In the control group 18.9% of all women with borderline dyskaryosis at baseline and 51.0% of those with mild dyskaryosis were eventually referred for colposcopy. After correction for loss to follow-up, we obtained adjusted colposcopy rates of
