title: Diagnostic value of endocervical curettage during colposcopy.
abstract: A retrospective study including patients with cytology, colposcopy and endocervical curettage (ECC) was carried out to compare ECC outcomes to final diagnosis. ECC was performed in 68 cases for a discordance between cytology and colposcopy and in 85 cases because the lesion was incompletely visible. Complete concordance between ECC and final diagnosis was obtained in 123 cases. ECC overestimated diagnosis in eight cases (5 true false positives) and underestimated it in 20 cases (6 true false negatives). Among the latter, ECC failed to recognize invasion in seven cases. Sensitivity, specificity, positive and negative predictive values of ECC to diagnose high grade cervical intraepithelial neoplasia (CIN) and invasive lesions together were 84%, 97%, 95% and 90%, respectively. Outcomes to diagnose invasive lesions were 22%, 100%, 100% and 95%, respectively. ECC sensitivity to diagnose endocervical lesions is satisfactory but its sensitivity to establish the diagnosis of invasion is very low. Consequently, a conization is advisable when ECC has diagnosed an endocervical lesion, especially a high grade CIN.
