Abstract

The BRCA 1/2 mutations are the most known typologies of hereditary breast cancer (BC). Studies among women carrying these mutations have showed preliminary evidence of a protective role of physical activity (PA) against BC, particularly during adolescence or early adulthood. Previous data confirmed a significantly lower BC prevalence in women reporting higher PA in their adolescence [1, 2]. In addition, on healthy pre-menopausal women at high risk of BC, the practice of PA showed that it raised adiponectin and lowered leptin, controlling for a change in body fat and suggesting the importance of adipokines in BRCA penetrance [3]. Aim of the current study was to assess the role of PA on BC risk factors in women carrying BRCA 1/2 mutations. Data analysis involved 63 women (47.6±12.4 years) with BRCA 1/2 mutations, in care at Fondazione IRCCS Istituto Nazionale dei Tumori, Milan. The participants filled in Godin-Shepard Leisure-Time Physical Activity Questionnaire for the evaluation of the PA levels. Moreover, they underwent to anthropometric, metabolic, and blood sample assessments. Data were analyzed with SPSS version 27. The women were classified as inactive (n=41) and active (n=22). Insulin levels were found significantly lower in active compared to the inactive group (p<.05); in addition, there were no differences for the other variables analyzed. The correlation analysis on the total sample showed that higher PA levels were significantly correlated with lower weight (r2=-0.26, p<.05), BMI (r2=-0.30, p<.05), hip circumference (r2=-0.30, p<.05), fat mass both in % (r2=-0.31, p<.05) and in kg (r2=-0.28, p<.05), and triglycerides (r2=-0.28, p<.05). These findings suggest that higher levels of PA can play an important and protective role against BC. Therefore, structured PA interventions could be a tool for modulate the penetrance of hereditary BC. References 1.
