Toledo E. et al. Mediterranean diet and invasive breast cancer risk among women at high cardiovascular risk in the PREDIMED trial: a randomized clinical trial. JAMA Intern Med 2015; 175: 1752–1760 Die Mittelmeerdiät, die den Verzehr von Obst und Gemüse fördert, Fisch statt rotem Fleisch empfiehlt und hin und wieder ein Glas Rotwein erlaubt, wird gemeinhin als gesundheitsfördernd angesehen. In der Vergangenheit haben bereits einige Beobachtungsstudien behauptet, dass die mediterrane Diät auch das Brustkrebsrisiko senken könne. Um diesen Effekt genauer zu untersuchen, verglich eine spanische Studie die Mittelmeerdiät mit einer fettarmen Diät hinsichtlich der Brustkrebsinzidenz.

Abstract Background Some endogenous hormones have been associated with breast cancer risk, but the nature of these relationships is not fully understood. Methods UK Biobank was used. Hormone concentrations were measured in serum collected in 2006–2010, and in a repeat subsample (N ~ 5000) in 2012–13. Incident cancers were identified through data linkage. Cox regression models were used, and hazard ratios (HRs) corrected for regression dilution bias. Results Among 30,565 pre-menopausal and 133,294 post-menopausal women, 527 and 2,997, respectively, were diagnosed with invasive breast cancer during a median follow-up of 7.1 years. Cancer risk was positively associated with testosterone in post-menopausal women (HR per 0.5 nmol/L increment: 1.18; 95% CI: 1.14, 1.23) but not in pre-menopausal women (pheterogeneity = 0.03), and with IGF-1 (insulin-like growth factor-1) (HR per 5 nmol/L increment: 1.18; 1.02, 1.35 (pre-menopausal) and 1.07; 1.01, 1.12 (post-menopausal); pheterogeneity = 0.2), and inversely associated with SHBG (sex hormone-binding globulin) (HR per 30 nmol/L increment: 0.96; 0.79, 1.15 (pre-menopausal) and 0.89; 0.84, 0.94 (post-menopausal); pheterogeneity = 0.4). Oestradiol, assessed only in pre-menopausal women, was not associated with risk, but there were study limitations for this hormone. Conclusions This study confirms associations of testosterone, IGF-1 and SHBG with breast cancer risk, with heterogeneity by menopausal status for testosterone.

Abstract Background Benign breast disease (BBD) is a strong breast cancer risk factor but identifying patients that might develop invasive breast cancer remains a challenge. Methods By applying machine-learning to digitized H&E-stained biopsies and computer-assisted thresholding to mammograms obtained circa BBD diagnosis, we generated quantitative tissue composition metrics and determined their association with future invasive breast cancer diagnosis. Archival breast biopsies and mammograms were obtained for women (18-86 years of age) in a case-control study, nested within a cohort of 15,395 BBD patients from Kaiser Permanente Northwest (1970-2012), followed through mid-2015. Cases (n = 514) who developed incident invasive breast cancer and controls (n = 514) were matched on BBD diagnosis age and plan membership duration. All statistical tests were 2-sided. Results Increasing epithelial area on the BBD biopsy was associated with increasing breast cancer risk (Odds ratio [OR]Q4 vs Q1=1.85, 95% confidence interval [CI] = 1.13-3.04; Ptrend=0.02). Conversely, increasing stroma was associated with decreased risk in non-proliferative, but not proliferative, BBD (Pheterogeneity=0.002). Increasing epithelium-to-stroma proportion [ORQ4 vs Q1=2.06, 95% CI = 1.28-3.33; Ptrend=0.002) and percent mammographic density (MBD) (ORQ4 vs Q1=2.20, 95% CI = 1.20-4.03; Ptrend=0.01) were independently and strongly predictive of increased breast cancer risk. In combination, women with high epithelium-to-stroma proportion/high MBD had substantially higher risk than those with low epithelium-to-stroma proportion/low MBD [OR = 2.27, 95% CI = 1.27-4.06; Ptrend=0.005), particularly among women with non-proliferative (Ptrend=0.01) versus proliferative (Ptrend=0.33) BBD. Conclusion Among BBD patients, increasing epithelium-to-stroma proportion on BBD biopsies and percent MBD at BBD diagnosis were independently and jointly associated with increasing breast cancer risk. These findings were particularly striking for women with non-proliferative disease (comprising approximately 70% of all BBD patients), for whom relevant predictive biomarkers are lacking.

The Impact

Diet is a modifiable component of lifestyle that could influence breast cancer development. The Mediterranean dietary pattern is considered one of the healthiest of all dietary patterns. Adherence to the Mediterranean diet protects against diabetes, cardiovascular disease, and cancer. Reported consumption of a Mediterranean diet pattern was associated with lower breast cancer risk for women with all subtypes of breast cancer, and a Western diet pattern was associated with greater risk. In this review, we contrast the available epidemiological breast cancer data, comparing the impact of consuming a Mediterranean diet to the Western diet. Furthermore, we will review the preclinical data highlighting the anticancer molecular mechanism of Mediterranean diet consumption in both cancer prevention and therapeutic outcomes. Diet composition is a major constituent shaping the gut microbiome. Distinct patterns of gut microbiota composition are associated with the habitual consumption of animal fats, high-fiber diets, and vegetable-based diets. We will review the impact of Mediterranean diet on the gut microbiome and inflammation. Outside of the gut, we recently demonstrated that Mediterranean diet consumption led to distinct microbiota shifts in the mammary gland tissue, suggesting possible anticancer effects by diet on breast-specific microbiome. Taken together, these data support the anti-breast-cancer impact of Mediterranean diet consumption.

Abstract Objectives We examined the prospective association between a Mediterranean diet pattern using four separate a priori indices of adherence and breast cancer risk in the Framingham Offspring (FOS) cohort. Methods The four indices included in this study reflect two different approaches to measuring adherence to a Mediterranean diet: a. scores based on population food intake distributions (i.e., the alternate Mediterranean Diet (aMED) and Mediterranean Diet (MDS) score); and b. scores based on recommended intakes of relevant foods (i.e., Mediterranean Style Dietary Pattern (MSDP) and Mediterranean Diet (MeDiet) scores). The scores were derived from a semi-quantitative food frequency questionnaire. Subjects included 1703 women, aged 30 years old and older, who were free of prevalent cancer. Each score was classified into three categories (low, moderate, and high) to evaluate the association between the Mediterranean diet and breast cancer risk (overall, post-menopausal, and hormone receptor positive) from 1991 through 2014. Cox proportional-hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs), adjusting for confounding by age, physical activity, waist-to-height ratio, pack-years of cigarette smoking, supplement use, diabetes status, age at menopause and total calorie intake. Results During a median follow-up of approximately 18 years, 93 breast cancer cases were documented. Women in the highest category of MSDP score or MeDiet score had approximately 45% lower breast cancer risks than women in the lowest categories (MSDP high category HR:0.56, 95% CI: 0.33–0.94; MeDiet high category HR: 0.55, 95% CI: 0.31–0.98). This effect was similar for post-menopausal breast cancer cases. In addition, the high (vs. low) MeDiet score was associated with 55% decreased risk of hormone receptor positive breast cancer (HR:0.45, 95% CI:0.23–0.87). Neither of the scores calculated on the basis of dietary intakes in the study population (i.e., aMED, MDS) was associated with breast cancer risk. Conclusions In this large prospective cohort, scores based on recommended intakes of relevant Mediterranean diet foods may lead to strong evidence of the inverse relation between a Mediterranean dietary pattern and incidence of breast cancer among women aged 30 years old or older in the US.
