Objective: To evaluate the prevalence of and predictors for underlying significant lesions in women with low-grade squamous intraepithelial lesion (LSIL) smears. Methods: Records were retrospectively reviewed for 208 women with LSIL who underwent colposcopy and histological evaluation from October 2004 through April 2009. Results: Mean age of the patients was 38.5 years. Forty-four (21.2%) women were nulliparous; 20 (9.6%) women were postmenopausal; 29 (13.9%) women tested positive for HIV. Thirty-three (15.9%) women were current users of combined oral contraceptive pills. The pathological results of initial colposcopic evaluations were: 63 (30.3%) with cervical intraepithelial neoplasia (CIN) 2-3; 62 (29.8%) with CIN 1; 4 (1.9%) with cervical cancer; and 79 (38.0%) with no epithelial lesion. Current use of combined oral contraceptive pills, a positive HIV test, and multiparity were significant independent predictors for high-grade disease. Conclusion: Approximately one-third of women with LSIL in our population have underlying significant lesions. Current use of combined oral contraceptive pills, a positive HIV test, and multiparity are significant predictors for high-grade lesions. © 2010 International Federation of Gynecology and Obstetrics.
