Prognostic Value of Endocervical Curettage at the Time of Colposcopic Assessment of the Uterine Cervix: Cross-Sectional Analytical Research

Abstract

Objective: This study aimed to investigate the necessity and diagnostic value of endocervical curettage (ECC) in cervical preneoplastic and neoplastic lesions. Material and Methods: A total of 296 patients who were admitted to the gynecologic oncology outpatient clinic at a single tertiary care center and who simultaneously underwent colposcopic biopsy and ECC between 2018 and 2020 were included in the study. Hematoxylin-Eosin (H&E), p16, and ki-67-stained preparations obtained from biopsy and curettage samples of the patients were analyzed by light microscope. Demographic data of the patients were obtained from the hospital system. Results were statistically and comparatively analyzed. Results: Cervical premalignant/malignant lesion was detected in 125 out of 296 patients and premalignant/malignant lesion was detected in 42 patients on ECC. Out of these 42 patients, 19 were diagnosed by ECC material alone. It was striking that all of the 5 HPV-18- positive patients were diagnosed with ECC material. When conization materials of CIN 2-3 patients were assessed with ECC results, it was observed that adenocarcinoma and glandular involvement were remarkably significant in ECC-positive patients. Conclusion: Our study involves important findings in the determination of the role of ECC in diagnosing cervical premalignant lesions. ECC simultaneously performed with colposcopic biopsy for appropriate women increases the diagnosticity of colposcopic biopsy procedure and gives information about glandular involvement. Moreover, it can decrease the risk of recurrence and minimize surgical margins.
