Phosphaturic mesenchymal tumours are a heterogeneous set of bone and soft tissue neoplasms that can cause a number of paraneoplastic syndromes such as tumour induced osteomalacia. The term phosphaturic comes from the common finding that these tumours secrete high levels of fibroblast growth factor 23 which causes renal phosphate wasting leading to hypophosphatemia. Phosphaturic mesenchymal tumours are rare and diagnosis is difficult. A very active 68 year old male presented with bone pain and muscle weakness...

Experimental studies suggest beneficial effects of antioxidants in digestive cancer prevention. However, epidemiological results are contrasting and few studies quantitatively assessed supplemental intake. This study aimed at investigating the associations between antioxidant intakes (dietary, supplemental and total) and digestive cancer risk. This prospective study included 38 812 middle-aged subjects (≥45 years) from the NutriNet-Santé cohort (2009-2016). Dietary data were collected using repeated 24 h records...

Background: Circulating concentrations of B vitamins and factors related to one-carbon metabolism have been found to be strongly inversely associated with lung cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. The extent to which these associations are present in other study populations is unknown. Methods: Within 20 prospective cohorts from the National Cancer Institute Cohort Consortium, a nested case-control study was designed including 5364 incident lung cancer case patients and 5364 control subjects who were individually matched to case patients by age, sex, cohort, and smoking status...

Breast cancer is one of the most common malignancies and bone is the commonest site of distant metastases. Evidences indicate that adequate supply of vitamin D will decrease the morbidity and mortality of breast cancer. However, the main role of vitamin D deficiency in breast cancer bone metastases remains unclear. In this study, the relationship between vitamin D and breast cancer bone metastases were evaluated. Results showed that 1,25(OH)2D3 can not only inhibit the proliferation, migration and invasion of breast cancer cell TM40D in vitro, but also attenuate the breast cancer cell TM40D-induced bone destruction in vivo, whose underlying mechanism was at least partially through decreasing the number of the osteoclasts...

BACKGROUND: Vitamin D deficiency may increase esophageal cancer risk. Vitamin D affects genes regulating proliferation, apoptosis, and differentiation and induces the tumor suppressor 15-hydroxyprostaglandin dehydrogenase (PGDH) in other cancers. This nonrandomized interventional study assessed effects of vitamin D supplementation in Barrett's esophagus (BE). We hypothesized that vitamin D supplementation may have beneficial effects on gene expression including 15-PGDH in BE. METHODS: BE subjects with low grade or no dysplasia received vitamin D3 (cholecalciferol) 50,000 international units weekly plus a proton pump inhibitor for 12 weeks...

PURPOSE OF REVIEW: The possibility to use vitamin D supplementation to improve muscle wasting, with particular focus on cancer cachexia, is discussed. RECENT FINDINGS: Vitamin D exerts biological actions on myogenic precursor proliferation and differentiation, impinging on muscle regeneration. However, the effects of VitD supplementation in diseases associated with muscle atrophy, such as cancer cachexia, are poorly investigated. Data obtained in experimental models of cancer cachexia show that the administration of vitamin D to tumor-bearing animals is not able to prevent or delay both muscle wasting and adipose tissue depletion, despite increased expression of muscle vitamin D receptor...

Psoriasis is a chronic inflammatory immune-mediated disorder associated and often coexisting with many other immune-related clinical conditions including those affecting the gastrointestinal tract. Data obtained from the reviewed literature suggest an association between psoriasis and pathologies of the oral cavity, both psoriasis-specific lesions, as well as non-specific, such as geographic tongue or fissured tongue. These findings show the importance of thorough examination of oral mucosa in psoriatic patients...

BACKGROUND: According to a small pilot study on palliative cancer patients at our ward, vitamin D supplementation had beneficial effects on pain (measured as opioid consumption), infections and quality of life (QoL) without having any significant side effects. OBJECTIVE: The primary objective of the 'Palliative-D' study is to test the hypothesis that vitamin D supplementation for 12 weeks reduces opioid consumption. The secondary objectives are to study if reduction of antibiotic consumption and fatigue as well as improvement in QoL assessments can be observed...

PURPOSE OF REVIEW: Polycystic ovary syndrome (PCOS) is defined by hyperandrogenism, irregular menses and polycystic ovaries when other causes are excluded. The possible implication of increased morbidity in PCOS for screening and follow-up is uncertain and is reviewed in this article. RECENT FINDINGS: The increased risk of type 2 diabetes and cardiovascular disease in PCOS is closely associated with BMI. Women with PCOS should be screened for the elements of the metabolic syndrome upon diagnosis...

Prostate cancer significantly affects the overall morbidity and mortality of malignant tumours in highly developed countries. Important risk factors include family predisposition and regional, racial and dietary determinants. The scientific literature contains a great deal of data on the role of calcium and dairy products in general in the process of neoplastic transformation of the prostate. This is most likely linked to the fact that changes in the concentration of calcium ions control such varied life processes as secretion of hormones and neurotransmitters, the level of cyclic nucleotides, and cell growth, division and differentiation...

PURPOSE: Vitamin D has been implicated in lowering lung cancer risk, but serological data on the association among never-smoking women are limited. We report results examining the association of serum 25-hydroxyvitamin D [25(OH)D] concentrations with lung cancer risk among female never smokers. We also examined whether the association was modified by vitamin D supplementation and serum vitamin A concentrations. METHODS: In the Women's Health Initiative, including the calcium/vitamin D (CaD) Trial, we selected 298 incident cases [191 non-small cell lung cancer (NSCLC) including 170 adenocarcinoma] and 298 matched controls of never smokers...

AIM: In recent years, it is believed that Vitamin D may play a protective role in some cancer types. Certain regions of the Vitamin D receptor (VDR) gene may show a genetic difference in structure. The most frequent polymorphisms in this gene are in Taq-1, Fok-1, and Bsm-1 regions. Some adult cancer types are associated with VDR gene polymorphism such as; colorectal carcinoma, breast carcinoma, and prostate carcinoma. Reviewing the medical literature, no such study had been done on children so far...

The main role of vitamin D is regulating bone metabolism and calcium and phosphorus homeostasis. Over the past few decades, the importance of vitamin D in non-skeletal actions has been studied, including the role of vitamin D in autoimmune diseases, metabolic syndromes, cardiovascular disease, cancers, and all-cause mortality. Recent evidence has demonstrated an association between low vitamin D status and autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease, and impaired vitamin D signaling has been reported in thyroid cancers...

The vitamin D related pathway has been evaluated in carcinogenesis but its genetic contribution remains poorly understood. We examined single-nucleotide polymorphisms (SNPs) in the vitamin D related pathway genes using data from a genome-wide association study (GWAS) of breast cancer in the African Diaspora that included 3,686 participants (1,657 cases). Pathway- and gene-level analyses were conducted using the adaptive rank truncated product test. Odds ratios (OR) and 95% confidence intervals (CI) were estimated at SNP-level...

Pharmacological doses (> 1mM) of ascorbate (a.k.a., vitamin C) have been shown to selectively kill cancer cells through a mechanism that is dependent on the generation of H2O2 at doses that are safely achievable in humans using intravenous administration. The process by which ascorbate oxidizes to form H2O2 is thought to be mediated catalytically by redox active metal ions such as iron (Fe). Because intravenous iron sucrose is often administered to colon cancer patients to help mitigate anemia, the current study assessed the ability of pharmacological ascorbate to kill colon cancer cells in the presence and absence of iron sucrose...

The biological effects mediated by vitamin D and vitamin D receptor (VDR) are involved in the regulation of multiple pathophysiologic processes, including calcium phosphorus metabolism, immune regulation, anti-inflammation, anti-infection and cancer prevention, etc. Autophagy is a eukaryotic cell lysosome-mediated catabolic pathway, which is classified into 3 different types: macroautophagy, microautophagy, and chaperone-mediated autophagy. Since autophagy is vital to maintain energy and metabolism in cells, autophagy dysfunction is closely associated with various pathological processes such as inflammation, infection and tumor...
