Clinical Usefulness of Computerized Colposcopy: Image Analysis and Conservative Management of Mild Dysplasia

From the Department of Obstetrics and Gynecology, Albert Einstein College of Medicine, Bronx, New York

Abstract

Objectives: The purposes of this study were to evaluate the clinical usefulness of computerized colposcopy and image analysis, to investigate the correlation between lesion size and grade of dysplasia, and to examine and record the Colposcope changes associated with progression or regression of cervical dysplasia.

Methods: Sixty-eight patients with a fully visualized squamocolumnar junction and a histopathologic diagnosis of mild dysplasia were serially monitored for a period of 1 year using computerized colposcopy and image analysis. All patients had baseline computer-assisted measurements of their cervical lesions and repeat measurements at 3-month intervals.

Results: The mean age of the patients was 31 years, and the mean size of the colposcopically visualized lesions was 58 mm². During the 12-month observation, 5.9% of the lesions increased in size, 32.4% decreased in size, 13.2% remained unchanged, 20.6% disappeared, and 27.9% completely changed location. In patients with an increase in lesion size {N=4), a repeat biopsy was performed, revealing a progression to moderate dysplasia. Treatment was withheld from patients whose lesions disappeared (N=14), decreased in size (JV=22), or remained unchanged (N=9). Active therapy was unnecessary in 66% of cases and repeat biopsy was avoided in 94.1%.

Conclusions: Computerized colposcopy provides objective information and may be an adjunct to cytology and histopathology in some cases. Computerized colposcopy replaces subjective colposcopic evaluation with objective computer assessment and may hold promise for conservative management of cervical dysplasia.
