Should women with genital condyloma acuminata have routine diagnostic colposcopy in addition to cervical smear screening?
We aimed to evaluate the difference in the pick up rate of high grade cervical abnormalities using both primary colposcopy and cervical smear compared with cervical cytology screen only on women with genital warts. We also wished to establish whether this group was at high risk of sexually transmittable infections (STIs) and whether there is a correlation between those with high grade CIN and other STIs. This was a retrospective analysis based in the Department of Genito-Urinary Medicine, Dundee Teaching Hospitals Trust, Dundee, UK. We studied all women (n =117) attending the Department with genital warts between January 1995 and March 1997 who were screened by both cervical cytology and colposcopy High grade cervical abnormalities (CIN II-CIN III) were diagnosed in 10 patients (8.5.%) using cervical screening only and in 41 patients (35%) (CIN II-III) when primary colposcopy and histopathology were undertaken. Of 117 women screened for sexual transmittable infection there were 53 with a positive diagnosis (48%). Of the 53 positive there were 17 women (30%) with high grade CIN. We conclude that women with genital warts are a high risk group, both in terms of having high grade cervical abnormalities and sexually transmittable infection. The result suggests that, when practicable primary colposcopy should be performed as a routine screening tool, on this group of patients over and above cervical cytology screening. All patients with genital warts should be referred to genitourinary medicine for STI screening.
