Frequency of factors associated with cervical premalignant lesions among women treated in Metropolitan Lima

Frecuencia de factores asociados a lesiones premalignas cervicales en mujeres atendidas en Lima Metropolitana

Abstract

Introduction: Cervical cancer is preceded by premalignant lesions such as cervical intraepithelial neoplasia (CIN). Objective: This study aimed to describe the frequency of factors associated with CIN in women treated at a Social Health Insurance (EsSalud) hospital in Metropolitan Lima during 2023 and 2024. Materials and Methods: We conducted a cross-sectional observational study through a review of clinical records at Hospital III Suárez Angamos in Metropolitan Lima. Women with a confirmed diagnosis of CIN (ICD-10 codes N87.9, N87.1, or D06.9) during 2023 and 2024 were included. Results: A total of 341 patients with a confirmed diagnosis of CIN were included: 34.6 percent had CIN I, 47.5 percent CIN II, and 17.9 percent CIN III. Among women with CIN, 69.8 percent were aged forty years or older, 60.1 percent had a higher education level, 89.7 percent reported no tobacco use, 58.9 percent were multiparous, 91.7 percent had five or fewer sexual partners, 63.5 percent did not report early initiation of sexual intercourse, and 72.1 percent had an interval of four years or more between menarche and first sexual intercourse. No statistically significant differences were found in the distribution of the evaluated factors according to lesion grade. Conclusions: Most women were diagnosed with CIN II, and the most frequent associated factors were multiparity and older age. These findings highlight the need to strengthen population-based cervical cancer screening.
