Concomitant endocervical curettage and cervical conization

Area of Science:

• Gynecologic Pathology
• Cervical Cancer Screening

Background:

• Cervical intraepithelial neoplasia (CIN) is a precursor to cervical cancer.
• Conization is a common treatment for CIN.
• Accurate assessment of residual disease after conization is crucial for patient management.

Purpose of the Study:

• To evaluate the utility of endocervical curettage (ECC) performed after cervical cone biopsy in predicting persistent CIN.
• To compare the diagnostic performance of ECC with the histological findings from the cone specimen's top margin.

Main Methods:

• A retrospective analysis of 94 cases where ECC was performed immediately after cervical cone excision.
• Histological examination of both ECC samples and cone biopsy specimens, focusing on the cone's top margin.
• Calculation of sensitivity and specificity for ECC and cone top margin in detecting persistent disease.

Main Results:

• Endocervical curettage (ECC) yielded insufficient material in 7 cases and contained CIN in 9 cases.
• The cone specimen's top margin showed CIN in 17 cases.
• Correlation between ECC and cone top margin histology was poor.
• ECC had a sensitivity of 0.50 and specificity of 0.95 for persistent disease.
• The cone top margin had a sensitivity of 0.80 and specificity of 0.88.

Conclusions:

• Endocervical curettage (ECC) provides minimal additional value in predicting persistent cervical intraepithelial neoplasia (CIN) after conization.
• The histological status of the cone specimen's top margin is a more reliable predictor of residual disease.
