    Vitamin D receptor activation reduces VCaP xenograft tumor growth and counteracts ERG activity despite induction of TMPRSS2:ERG.
    Oncotarget 2017 May 18. Epub 2017 May 18.
    Department of Molecular and Cellular Biology, Baylor College of Medicine, Houston, TX, USA.
    Whether vitamin D is chemopreventive and/or has potential therapeutically in prostate cancer is unresolved. One confounding factor is that many prostate cancers express a TMPRSS2:ERG fusion gene whose expression is increased both by androgens and by vitamin D receptor (VDR) activation. Two challenges that limit VDR agonist use clinically are hypercalcemia and the cooperation of VDR with ERG to hyper-induce the 1α,25-dihydroxyvitamin D3 metabolizing enzyme, CYP24A1, thus reducing VDR activity.

    Myeloma bone disease: pathogenesis and treatment.
    Clin Adv Hematol Oncol 2017 Apr;15(4):285-295
    Harvard Medical School, Boston, Massachusetts.
    Bone involvement manifesting as osteolytic bone disease (OBD) or osteopenia is one of the defining features of multiple myeloma (MM). Osteolytic lesions develop in nearly 90% of patients with MM, and these are frequently complicated by skeleton-related events (SREs) such as severe bone pain, pathologic fractures, vertebral collapse, hypercalcemia, and spinal cord compression. SREs have a negative effect on patients' quality of life and affect their long-term outcomes, including survival. Read More

    [Treatment of bone metastases: bisphosphonates and denosumab].
    Magy Onkol 2017 Jun 23;61(2):175-180. Epub 2016 Jul 23.
    Onkológia, XV. ker. Egészségügyi Intézményei, Budapest, Hungary.
    Some disseminated tumor cells (as "seeds") feel well in the skeletal tissue, as a "soil", but the humoral crosstalk between tumor cells and bone cells disrupts the normal bone homeostasis (remodeling), which leads to a vicious circle, the multiple bone metastatic disease. The tumor cells could stimulate bone resorption, bone neo-formation or both, characteristic of the primary tumor. This usually incurable condition involves serious consequences, as fractures, pain, surgeries, irradiations, plegias, hypercalcemia, etc. Read More

    A Review of Phosphate Binders in Chronic Kidney Disease: Incremental Progress or Just Higher Costs?
    Drugs 2017 Jun 5. Epub 2017 Jun 5.
    Department of Clinical Pharmacy, College of Pharmacy, University of Tennessee, Memphis, USA.
    As kidney disease progresses, phosphorus retention also increases, and phosphate binders are used to treat hyperphosphatemia. Clinicians prescribe phosphate binders thinking that reducing total body burden of phosphorus may decrease risks of mineral and bone disorder, fractures, cardiovascular disease, progression of kidney disease, and mortality. Recent meta-analyses suggest that sevelamer use results in lower mortality than use of calcium-containing phosphate binders. Read More

    Humoral Hypercalcemia of Malignancy with a Parathyroid Hormone-Related Peptide-Secreting Intrahepatic Cholangiocarcinoma Accompanied by a Gastric Cancer.
    Case Rep Endocrinol 2017 10;2017:7012520. Epub 2017 May 10.
    Department of Endocrinology and Metabolism, Nagoya City West Medical Center, 1-1-1 Hirate-cho, Kita-ku, Nagoya 462-8508, Japan.
    Humoral hypercalcemia of malignancy (HHM) is caused by the oversecretion of parathyroid hormone-related peptide (PTHrP) from malignant tumors. Although any tumor may cause HHM, that induced by intrahepatic cholangiocarcinoma (ICC) or gastric cancer (GC) is rare. We report here a 74-year-old male who displayed HHM with both ICC and GC and showed an elevated serum PTHrP level. Read More

    Hypercalcaemia - presentation and management .
    Clin Med (Lond) 2017 Jun;17(3):270-273
    Department of Diabetes & Endocrinology, Norfolk and Norwich University Hospital; Norwich Medical School; NIHR CRN:Eastern Research Network, Norwich, UK.
    Hypercalcaemia is a common disorder normally caused by primary hyperparathyroidism (PHPT) or malignancy. A proportion of cases present as an emergency, which carries a significant mortality. Emergency management of hypercalcaemia is based on intravenous rehydration with normal saline but when this is inadequate, bisphosphonate therapy is used; more recently the novel anti-resorbtive agent denosumab has been shown to have a useful role in treatment.
