BACKGROUND Diets against cancer are attractive for patients who try to influence disease progression. METHODS In order to determine the most influential cancer diets in Germany, we analyzed the chatroom for cancer patients "Krebs-Kompass", the search machines Google and Bing and our own counseling experience as experts. We conducted a systematic(More)
BACKGROUND Excess body weight and a sedentary lifestyle are associated with the development of several diseases, including cardiovascular disease, diabetes and cancer in women. One proposed mechanism linking obesity to chronic diseases is an alteration in adipose-derived adiponectin and leptin levels. We investigated the effects of 12-month reduced calorie,(More)
BACKGROUND Many cancer patients use cancer diets. MATERIALS AND METHODS We listed 13 cancer diets simulating an internet search for which we systematically reviewed clinical data. In the next step we derived recommendations on counseling patients using a Delphi process. RESULTS We evaluated the following diets: raw vegetables and fruits, alkaline diet,(More)
Folate-mediated one-carbon metabolism is essential for DNA synthesis, repair, and methylation. Perturbations in one-carbon metabolism have been implicated in increased risk of some cancers and may also affect inflammatory processes. We investigated these interrelated pathways to understand their relation. The objective was to explore associations between(More)
Vitamin D and folate are associated with decreased colorectal cancer risk and their association with colorectal cancer prognosis is under investigation. We assessed the levels of plasma 25-hydroxyvitamin D3 (25(OH)D3), folate and vitamin B12 in an international pilot study in order to determine variability of these biomarkers based on geographical location.(More)
Sarlak et al. [1] discuss in greater detail the role of adiponectin in cancer risk and the ability of lifestyle intervention to alter adiponectin or leptin levels. They note that adipose tissue contributes to whole-body metabolism with multiple effects on biomarkers of the metabolic syndrome and fat tissue oxidation. They also point out that significant(More)
Pancreatic phospholipase A2, product of PLA2G1B, catalyzes the release of fatty acids from dietary phospholipids.Diet is the ultimate source of arachidonic acid in cellular phospholipids, precursor of eicosanoid signaling molecules, linked to inflammation, cell proliferation and colorectal carcinogenesis. We evaluated the association of PLA2G1B tagging(More)
INTRODUCTION Maintenance of normal weight and higher levels of physical activity are associated with a reduced risk of several types of cancer. Because genomic instability is regarded as a hallmark of cancer development, one proposed mechanism is improvement of DNA repair function. We investigated links between dietary weight loss, exercise, and strand(More)
Physical activity plays an important role in colorectal cancer and accelerometry is more frequently used to measure physical activity. The aim of this study was to evaluate feasibility of physical activity measurement by accelerometry in colorectal cancer patients under free-living conditions at 6, 12 and 24 months after surgery, to evaluate the appropriate(More)
Adipose tissue plays a role in obesity-related cancers via increased production of inflammatory factors, steroid hormones, and altered adipokines. The impact of weight loss on adipose tissue gene expression may provide insights into pathways linking obesity with cancer risk. We conducted an ancillary study within a randomized trial of diet, exercise, or(More)
