Colposcopy in the diagnosis of human papilloma virus infection, cervical intraepithelial neoplasia and invasive carcinoma

ABSTRACT

Colposcopic diagnosis of 156 different lesions of the cervix was compared with histologic examination of the cervical punch biopsies. Colposcopy showed high degree of sensitivity and specificity [96% and 99.2%] in cases of carcinoma of the cervix. In cervical intraepithelial neoplasia [CIN] it showed a sensitivity of 82.8% and specificity of 49.6%, while in subclinical papilloma virus infection [SPI], it showed high degree of specificity [93.7%] but poor sensitivity [19.7%]
