Risk factors for pathological upgrading in perimenopausal women with cervical intraepithelial neoplasia grade 2/3 following conization. Issue 43 (28th October 2022) - Jia, Mingyu
Abstract : Postmenopausal women have a high risk for pathological upgrading in conization specimens due to pathological changes of the cervix. This study aimed to investigate the risk factors for pathological upgrading in conization specimens in Chinese women with cervical intraepithelial neoplasia grade 2/3 (Cervical intraepithelial neoplasia 2/3) ≥ 50 years of age. From January 2015 to December 2019, 443 CIN2/3 patients ≥ 50 years of age were retrospectively included and divided into the upgrade group (n = 47) and the non-upgrade group (n = 396) according to the presence or absence of pathological upgrading in the conization specimens. Multivariate logistic regression model was performed to analyze risk factors associated with pathological upgrading. The upgrade group was more likely to have gravidity < 2 times, postmenopausal period ≥ 5 years, higher incidences of endocervical glandular involvement (EGI) and human papillomavirus (HPV) 16/18 infection, as well as a lower incidence of cervical contactive bleeding and fewer cases undergoing endocervical curettage (all P < .05) than the non-upgrade group. Multivariate model showed that factors associated with pathological upgrading were postmenopausal period ≥ 5 years (OR = 2.55), EGI (OR = 17.71), endocervical curettage (OR = 0.33), and HPV type 16/18 (OR = 3.41) (all P < .05). The receiver operating characteristic analysis showed an area under curve of 0.782 ( P < .001). Pathological upgrading in conization specimens is not uncommon in Chinese CIN2/3 patients ≥ 50 years of age. For those with high-risk factors of pathological upgrading (postmenopausal period ≥ 5 years, EGI, and HPV 16/18 infection), the follow-up interval can be appropriately shortened, and active intervention could be considered.
