Cytobrush in evaluation of cervical dysplasia. Is cervical curettage necessary?

203 patients suspected of having dysplasia were evaluated by colposcopy, cytologic smear including cytobrush, endocervical curettage, biopsy and conization. The results obtained on the basis of the final cone suggested that directed biopsies and cytological smear by spatula and cytobrush more accurately define the dysplastic lesion than do biopsies and endocervical curettage. Conization seemed necessary for the evaluation of the cervical lesion in patients revealing non-classified dysplasia at successive examinations.
