Significance of positive endocervical curettage in predicting endocervical canal involvement in patients with cervical intraepithelial neoplasia.

A total of 108 patients with positive endocervical curettage who underwent cone biopsy were carefully examined to determine the accuracy of endocervical curettage (ECC) in predicting endocervical canal involvement with cervical intraepithelial neoplasia (CIN). The data suggest a 63% correlation between positive ECC and endocervical canal involvement: 72.4% of patients with CIN III on cervical biopsy had endocervical canal involvement compared to 27.3% who had CIN I. Two patients with positive ECC were found to have invasive cancer on cone biopsy.
