Colposcopy in the diagnosis of cervical neoplasia.
Two hundred and ninety one women were evaluated for cervical cancer by cytology and colposcopy. Of these, 152 patients underwent colposcopically directed biopsy for histological evaluation. Colposcopy and cytology were in agreement in 88 per cent of cases whereas colposcopy and histopathology were in agreement in 79 per cent of cases. Cytology underestimated the severity of the lesion in nine per cent while colposcopy underestimated the lesion in 7.2 per cent (False negative rate). In 13.8 per cent of cases colposcopy overestimated the lesion (False positive rate). The cone biopsy rate in this series was 30 per cent. We conclude that since colposcopy shows excellent correlation with histopathology, it will be a useful tool to reduce cone biopsy rates, particularly in younger women in the child-bearing age group.
