Abstract:

The prevalence of gestational breast cancer (GBC) is 1:3,000-10,000 pregnancies. The objective is to find out the risk factors associated with GBC. It’s a case-control study spanning the period between January 2004 and December 2014, at a reference maternity for high risk pregnancies, in Rio de Janeiro. For each case, two controls were recruited, in a total of 21 GBC cases and 42 controls. Data were obtained through review of medical and delivery records. Reproductive, obstetrical, sociodemographic and general health characteristics were checked. Results: The mean age of pregnant women in both groups was 35.5 years. The mean age at first period was also similar (12.3 years) in both groups. Maternal age at first pregnancy was over 30 years in 28.6% of the patients with GBC and in 2.4% of the control group (p=0.03). Crude and adjusted odds ratio and their respective CI95% were calculated through conditional logistic regression paired by maternal age.The results show the risk for GBC increases 27% for each additional year of maternal age at first pregnancy (p
