    The Impact of Breast Cancer Screening Among Younger Women in the Barretos Region, Brazil

    Aim: To verify the impact of breast cancer screening in women aged 40-49 years in one region of Brazil. Patients and Methods: This is a cross-sectional study, targeted to asymptomatic women aged 40-69 years who had breast cancer screening mammography performed between January 2003 and December 2007. Logistic regression was used to estimate the risk of breast cancer by age groups (40-49, 5059, 60-69 years). Results: Of the 27,133 screened women, 51.9% (14,082) were aged between 40-49 years. The odds ratio (OR) of breast cancer among the 45-49 year age cohort was not significantly different from that of 60 to 69-year-old women (OR=0.64; 95% Confidence Interval 0.39 to 1.03). Conclusion: The risk of breast cancer among women aged 45 to 49 years is equivalent to that of women aged 60 to 69 years, indicating that breast cancer screening in this region of Brazil should start at the age of 45 years or immediately thereafter.

    Polymorphisms of estrogen receptor-alpha gene in Brazilian women with high breast density after menopause
    (2013) SOUZA, Marilene Alicia; FONSECA, Angela Maggio; BAGNOLI, Vicente R.; BARROS, Nestor de; FRANZOLIN, Solange O. B.; CARVALHO, Katia C.; SOARES- JR., Jose Maria; BARACAT, Edmund C.
    The association of genetic polymorphism in the estrogen receptor alpha (ER alpha) gene and risk for diseases including breast cancer (BC) has been the subject of great interest. Objective: Checking on women with high breast density after menopause, the frequency of the Pvull and Xbal polymorphisms of the ER alpha gene and the correlation between them and the known risk factors for breast cancer. Method: Observational study with 308 women between 45 and 65 years old with high breast density, without hormonal therapy, menstruation for a year or more, breast and ovarian cancer history. It was characterized in clinical history and physical examination: menarche, menopause, parity, family history of BC, smoking, alcohol intake and body mass index. Results: The allelic and genotypic frequencies for ER alpha-Pvull and Xbal: p = 43.99%; p = 56.01%; pp = 32.14%; Pp = 47.73% and PP = 20.13%; X = 41.56%; x = 58.44%; xx = 33.44%; Xx = 50.00% and XX = 16.56%, respectively. The most frequent risk factors for BC: menarche before 12 years old (35.38%), nulliparity or first child after 28 years old (41.66%), family history of BC (19.16%) and overweight/obesity (62.01%). Conclusion: Allelic and genotypic distribution similar to literature. The risk factors for BC were more prevalent in women with high breast density but without significant associations with these polymorphisms.
