High-grade squamous intraepithelial lesions in pregnant and non-pregnant women

Objectives: To evaluate if the prevalence of cervical smear results varies between pregnant and nonpregnant women stratified by age group.Study design: Observational analytical study with a total sample of 1,336,180 pregnant and nonpregnant women, aged between 20 and 34 years, who underwent cervical cancer screening in the Primary Health Care of the national health system in the area of Campinas in Brazil during the period of 2005-2009. The source is the information system for cervical cancer screening. Data collected on abnormal cervical smears were analyzed using the Chi-square test and Fisher's exact test and the magnitude of the association between pregnancy and high-grade squamous epithelial lesions was analyzed by odds ratio (OR) and estimated values with confidence intervals (CI) of 95%.Results: 15,190 pregnant women and 395,961 non-pregnant women were analyzed and fulfilled the inclusion criteria. Regardless of age, no statistical differences were observed for high-grade squamous intraepithelial lesion prevalence (OR 0.90; CI 0.66-1.23). Taking into account the five-year age groups, however, low-grade squamous intraepithelial lesion was less prevalent in pregnant women aged 20-24 (OR 0.71; 0.54-0.95) and 25-29 years (OR 0.56; 0.35-0.89); also, atypical squamous cells of undetermined significance was more prevalent in non-pregnant women aged 25-29 years (OR 0.72; 0.54-0.97).Conclusion: The study showed that the cytological prevalence of high-grade squamous intraepithelial lesion was similar in pregnant and non-pregnant women, regardless of age. The results indicate that there are no reasons for specific approaches to cervical cancer screening for pregnant women. The examination should be carried out only on pregnant women who have not been tested according to current recommendations. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

Cigarette smoking and high-risk HPV DNA as predisposing factors for high-grade cervical intraepithelial neoplasia (CIN) in young Brazilian women

Background. This cross-sectional study was designed to evaluate the role of cigarette smoking and high-risk HPV types as risk factors of CIN 2 and 3 in young, sexually active Brazilian women. Materials and method. A series of 100 consecutive women with abnormal Pap smears were recruited, subjected to colposcopy, punch biopsy, and questionnaire for their social, sexual and reproductive factors. Of these, 77 women between 20 and 35 years of age (median 26.5 years) with biopsy-confirmed CIN 1 or CIN 2 and 3, were enrolled in this study. Representative samples from the exocervix and endocervix were obtained for HPV testing with the Hybrid Capture HPV-DNA assay, including the probes for the oncogenic HPV types (16, 18, 31, 33, 35, 45, 51, 52 and 56). Results. The overall rate of CIN 2 and 3 was 23/77 (29.8%). The women with CIN 1, 2 and 3 did not differ from each other with regard to their age, race, schooling, marital status, life-time number of sexual partners, age at first intercourse, use of oral contraceptives, or parity. However, current cigarette smoking was strongly associated with CIN 2 and 3 (p < 0,001), and among smokers, the risk of high-grade CIN increased in parallel with the time of exposure (years of smoking) p = 0.07), HPV-DNA of the oncogenic types was detected in 43 (56%) women, the risk of being HPV DNA-positive was significantly higher in CIN 2 and 3 as compared with CIN 1 (p = 0.037). Importantly, the prevalence of high-risk HPV types was significantly higher in cigarette smokers than in non-smokers (p = 0.046). Conclusions. The results indicate that the severity of CIN lesions was clearly related to two fundamental risk factors: 1) high-risk HPV types, and 2) current cigarette smoking. These two risk factors were closely interrelated in that the high-risk HPV types were significantly more frequent in current smokers than in non-smokers, suggesting the possibility of a synergistic action between these two risk factors in cervical carcinogenesis.
