    Abstract:
    OBJECTIVE: Performing endocervical curettage (ECC) at colposcopy may increase the yield of cervical intraepithelial neoplasia grade 2 (CIN2) or worse (CIN2+) compared to biopsies alone. The additional benefit of ECC in detecting CIN2+ was studied in women with lesion-targeted biopsies (low-grade or worse impression) and women with biopsies of normal-appearing cervix (less than low-grade impression). METHODS: In this subanalysis of a multicenter study, 126 women referred to colposcopy who had an ECC were included. Multiple directed biopsies were taken from lesions, and a nontargeted biopsy was added if fewer than 4 biopsies were collected. Risk strata of CIN2+ were evaluated based on cytology and colposcopic appearance to identify women for whom ECC would be most valuable. RESULTS: The CIN2+ yield of ECC in addition to biopsies was 15 (11.9%) of 126. In women with lesion-targeted biopsies and ECC, the CIN2+ yield of targeted biopsies was 34 (51.5%) of 66, the yield of additional nontargeted biopsies was 1 (1.5%) of 66, and the additional CIN2+ yield of ECC was 5 (7.6%) of 66. The yield in women with nontargeted biopsies only and ECC was 5 (8.3%) 60, and the additional yield for ECC was 10 (16.7%) of 60. Endocervical curettage did not find disease in women with atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion. CONCLUSIONS: In women with less than low-grade impression and especially those with unsatisfactory colposcopy, the yield of CIN2+ was higher for ECC compared to nontargeted biopsies. The highest yield of CIN2+ from ECC was observed in women with high-grade squamous intraepithelial lesion and less than low-grade impression, suggesting that disease is higher up in the endocervix in this group.
