Background - The Mediterranean diet has been associated with lower risk of breast cancer (BC) but evidence from prospective studies on the role of Mediterranean diet on BC survival remains sparse and conflicting. We aimed to investigate whether adherence to Mediterranean diet prior to diagnosis is associated with overall and BC-specific mortality.<p> <p>Methods - A total of 13,270 incident breast ...

Background - Since the first version of the dietary inflammatory index (DII®) developed in the past decade, several other versions have been developed. However, to date no study has attempted to compare these versions with respect to their associations with biomarkers of inflammation.<p> <p>Objective - We aimed to investigate the relationship between four dietary inflammatory scores [DII, two ...

Background: Infammation has been hypothesized to play a role in the development and progression of breast can‑ cer and might diferently impact breast cancer risk among pre and postmenopausal women. We performed a nested case-control study to examine whether pre-diagnostic circulating concentrations of adiponectin, leptin, c-reactive protein (CRP), tumour necrosis factor-α, interferon-γ and 6 ...

Norwegians are the second highest consumers of coffee in the world. Lately, several studies have suggested that beneficial health effects are associated with coffee consumption. By analyzing whole-blood derived, microarray based mRNA gene expression data from 958 cancer-free women from the Norwegian Women and Cancer Post-Genome Cohort, we assessed the potential associations between coffee consumption ...

Background - Trans fatty acids (TFAs) have been hypothesised to influence breast cancer risk. However, relatively few prospective studies have examined this relationship, and well-powered analyses according to hormone receptor-defined molecular subtypes, menopausal status, and body size have rarely been conducted.<p> <p>Methods - In the European Prospective Investigation into Cancer and Nutrition ...

<p><i>Background</i>: There is a large body of evidence demonstrating long-lasting protective effect of each full-term pregnancy (FTP) on the development of breast cancer (BC) later in life, a phenomenon that could be related to both hormonal and immunological changes during pregnancies. In this work, we studied the pregnancy-associated differences in peripheral blood gene expression profiles between ...

Analysis of blood RNA transcription profiles is hindered by ex vivogene expression changes, as well as degradation and loss of RNA over time during specimen transportation and storage. The PAXgeneBlood RNA System was developed by PreAnalytiXto overcome these problems. So far, quality control data has shown that the PAXgene Blood RNA System stabilizes and preserves RNA in blood specimens for up to ...

<i>Objective</i> - This explorative study aimed to assess if there are any time-dependent blood gene expression changes during the first one to eight years after breast cancer diagnosis, which can be linked to the clinical outcome of the disease.<br><br> <i>Material and methods</i> - A random distribution of follow-up time from breast cancer diagnosis till blood sampling was obtained by a nested, ...

Evidence linking coding germline variants in breast cancer (BC)-susceptibility genes other than BRCA1, BRCA2, and CHEK2 with contralateral breast cancer (CBC) risk and breast cancer-specific survival (BCSS) is scarce. The aim of this study was to assess the association of protein-truncating variants (PTVs) and rare missense variants (MSVs) in nine known (ATM, BARD1, BRCA1, BRCA2, CHEK2, PALB2, RAD51C, ...
