OBJECTIVE: To examine previous Pap smear history in women screened for cervical cancer with cytological or histological abnormalities. METHODS: Cross-sectional study in a sample of 5,485 women (15-65 years old) who self-referred to cervical cancer screening in Sao Paulo and Campinas, Southeastern Brazil, between February 2002 and March 2003. A behavioral questionnaire was applied and cervical specimens were obtained for testing by Pap smears or liquid-based cytology. Women who had abnormal cytology were referred for colposcopic examination and, if abnormal, for cervical punch biopsy. To explore factors associated to cervical abnormalities Pearson's chi-was conduted square test at a 5% significance level. RESULTS: Cytological abnormalities were found in 354 women (6.4%) and included 41 high-grade squamous intra-epithelial lesions and 3 carcinomas; 92.7% were normal results. Colposcopy was performed in 289 women, and 145 (50.2%) showed abnormal results. Punch biopsies showed 14 cervical intraepithelial neoplasias grade 3 and 4 carcinomas. Previous Pap smears were reported in all women who had cytology suspected of carcinoma, 97.6% of those with high-grade squamous intra-epithelial lesions, all women with histological diagnosis of carcinoma and 92.9% of those who had cervical intraepithelial neoplasias grade 3 histologically. Previous Pap smear in the last tree years was reported by 86.5% and 92.8% of women with abnormal cytology and biopsy, respectively. CONCLUSIONS: There was no statistically significant difference regarding the number of Pap tests and time since their last test between women with histologically diagnosed carcinoma and cervical intraepithelial neoplasia grade 3 compared with those with normal cytology.
