Summary:Background Healthy lifestyle, including caloric restriction, balanced diet and physical activity, is important in primary and secondary prevention of breast cancer (BC). It is known that Mediterranean diet reduces metabolic syndrome and insulin resistance that are associated with increased risk of BC onset and recurrence. Physical activity decreases BMI, blood concentrations of testosterone, estrogens, insulin, its resistance and strengthens anti-inflammatory pathways against tumor cells. Since January 2014, at our Institution we promoted a project named “Lifestyle Program” for high risk BC patients underwent to primary surgery. Here we presented the results of 12 months of “Lifestyle Program”. Patients and methods Since January 2014 we have prospectively enrolled all high risk patients between 18 and 70 years treated to our department for invasive early-stage breast cancer (stage I-III). High risk has been defined by one or more of the following inclusion criteria: body mass index (BMI) > 25, diagnosis of metabolic syndrome, increased level of blood testosterone and/or insulin. All high risk patients receive a periodical personalized educational intervention by a physiatrist for physical activity and by a nutritionist for a mediterranean diet low in animals fat and enriched of fibers, fruits and vegetables. All patients underwent to screening for anxiety and depression through HADS questionnaire scores. All data were analyzed by Chi-square test assuming statistical significance at p<0.05. Results 98 BC patients were included; 21.4% of them had a metabolic syndrome. Median age was 56 years old (range 27-75). Most of patients enrolled had ER+ (85.7%), Her2/neu negative (79.6%), stage I (48%) BC. We observed a statistically significant reduction of BMI (BMI>25 in 94.9% of pts at baseline vs 63.2% after 12 months of lifestyle; p=<0.0001), glycemic (>110 mg/dl in 23.5% of pts at baseline vs 10.2% at 12 months; p=<0.0001), insulin levels (>27 uU/ml in 20.6% of pts at baseline vs 2.9% after 12 months; p<0.0001), testosterone (>1,2 ng/ml in 17.6% of pts at baseline vs 4.1% at 12 months; p<0.0001), cholesterol (>200 mg/dl in 46.9% of pts at baseline vs 35.7% at 12 months; p<0.0001), triglycerides (>170 mg/dl in 13.3% of pts at baseline vs 10.2% at 12 months; p<0.0001) and arthralgia (37.7% at baseline vs 17.3% at 12 months; p=0.0008). We also noted a significantly reduction of anxiety and depression after 12 months of lifestyle program (25.4% and 12% respectively at diagnosis vs 13.4% and 4.5% at 12 months respectively; p=0,0064 and p<0.0001). Conclusions Promoting healthy lifestyle can reduce risk factors involved in BC recurrence and ensure psychological benefit and compliance to endocrine therapy. A multidisciplinary approach allows greater adherence to healthy attitudes in BC high risk patients.
