AIM AND BACKGROUND To evaluate the cost effectiveness of screening by colposcopy compared to conventional cytology. METHODS A prospective study was performed in the Florence District screening center on 3,000 consecutive women, self referring, who were examined by cytology and colposcopy in a blind fashion. Further assessment was based on cytologic report or on colposcopy-directed punch biopsy. Actual costs of the whole screening process were known. The cost effectiveness of different possible simulated screening scenarios was then determined. RESULTS Overall, 18 high-grade lesions (CIN3 = 9, CIN2 = 9) were detected. Four different screening scenarios were compared, namely a) cytology alone, b) cytology + repeat smear for ASCUS (atypical squamous cells of undeterminate significance) cases, c) colposcopy + cytology for cases of condyloma at punch biopsy, and d) colposcopy alone. Although they had a higher cost per examined woman (a) = 17.98, b) = 19.40, c) = 23.86, d) = 22.10 US$), scenarios c) and d) had a higher relative sensitivity (a = 44.4, b = 61.1, c = 100, d = 88.8%) and a lower cost per high-grade lesion detected (a = 6,743, b = 5,291, c = 3,977, d = 4,144 US$). CONCLUSIONS Screening by colposcopy is a feasible procedure which is more sensitive and more cost effective than conventional cytology screening. At least in those settings where access to cytopathology may be difficult, screening by colposcopy should be considered as a possible alternative.

Review on the medical and health economic evidence for an inclusion of colposcopy in primary screening programs for cervical cancer

INTRODUCTION With 3.2% of all cancer cases in 2002, cervical carcinoma is the tenth most common cancer in Germany and causes 1.8% of all cancer deaths in women in Germany. To date diagnosis in Germany solely has been based on cervical cytology which has been criticised due to its low sensitivity and consequently high rate of false negative results. OBJECTIVES How does colposcopy compare to cy...
