title: Colposcopic evaluation of patients with abnormal cervical cytology.
abstract: Because of suspicious or abnormal smears, 620 patients were referred to the Colposcopy Clinic of the British Columbia Cancer Institute between 1st March 1973 and 31st December 1974; it was possible to make a colposcopic examination in 549 of these patients (88.5 per cent). The colposcopic impression was within one histological grade of a colposcopically-directed biopsy in 476 patients (86 per cent). There were 221 patients who had a cone biopsy after a colposcopically-directed biopsy and in 192 of these (87 per cent) the two biopsies were within one histological grade of each other; but there were two patients with occult invasive carcinoma in a cone biopsy and only carcinoma in situ in a directed biopsy. In the same group of 221 patients the colposcopic evaluation and final diagnosis (the most advanced histological lesion seen in biopsy) agreed in all but seven patients.
