MedWire News - Oncology - Serum 25(OH)D levels linked to prostate cancer prognosis - 0 views

  • The researchers conclude: “This study shows a strong association between 25(OH)D levels and cause-specific mortality in patients with prostate cancer. The strength of the association indicates that prostate cancer patients can benefit from increasing the level of serum 25(OH)D if it is below 50 nmol/l.”

    MedWire News: Serum levels of 25-hydroxy vitamin D (25(OH)D) play a role in prostate cancer disease progression and are a potential prognostic indicator, Norwegian study findings suggest.

Vitamin D levels associated with survival in lymphoma patients - 0 views

  •  
    ScienceDaily (Dec. 5, 2009) - A new study has found that the amount of vitamin D in patients being treated for diffuse large B-cell lymphoma was strongly associated with cancer progression and overall survival. The results will be presented at the annual meeting of the American Society of Hematology in New Orleans. Also, several recent reports have concluded that vitamin D deficiency is associated with poor outcomes in other cancers, including breast, colon and head and neck cancer. This is the first study to look at lymphoma outcome.

Cancer immunology - Wikipedia, the free encyclopedia - 0 views

  •  
    Cancer immunology is the study of interactions between the immune system and cancer cells (also called tumors or malignancies). It is also a growing field of research that aims to discover innovative cancer immunotherapies to treat and retard progression of this disease. The immune response, including the recognition of cancer-specific antigens is of particular interest in this field as knowledge gained drives the development of new vaccines and antibody therapies. For instance in 2007, Ohtani published a paper finding tumour infiltrating lymphocytes to be quite significant in human colorectal cancer.[1] The host was given a better chance at survival if the cancer tissue showed infiltration of inflammatory cells, in particular lymphocytic reactions. The results yielded suggest some extent of anti-tumour immunity is present in colorectal cancers in humans.

DCA Update - Big Pharma/Glacial Rate of Progress | Uncommon Descent - 0 views

  •  
    Dichloroacetate (DCA) Promising for Endometrial Cancer DCA virtually disappeared from the news about a year ago when it was forced off the open market by the FDA and all research into its efficacy as a cancer therapeutic had to go through officially sanctioned channels. I've kept track of it all this time through Google Email Alerts. This is the first bit of news on it in relation to cancer in a long time.

    Circulating 25-hydroxyvitamin d levels and survival in patients with colorectal cancer. Ng K, Meyerhardt JA, Wu K, Feskanich D, Hollis BW, Giovannucci EL, Fuchs CS. J Clin Oncol. 2008 Jun 20;26(18):2984-91. PMID: 18565885 DOI: 10.1200/JCO.2007.15.1027 Conclusion Among patients with colorectal cancer, higher prediagnosis plasma 25(OH)D levels were associated with a significant improvement in overall survival. Further study of the vitamin D pathway and its influence on colorectal carcinogenesis and cancer progression is warranted.

    Induction of ovarian cancer cell apoptosis by 1,25-dihydroxyvitamin D3 through the down-regulation of telomerase. Jiang F, Bao J, Li P, Nicosia SV, Bai W. J Biol Chem. 2004 Dec 17;279(51):53213-21. Epub 2004 Oct 12. PMID: 15485861 doi: 10.1074/jbc.M410395200 Overall, the study suggests that the down-regulation of telomerase activity by 1,25(OH)2VD3 and the resulting cell death are important components of the response of OCa cells to 1,25(OH)2VD3-induced growth suppression. Progressive shortening of telomere associated with cell divisions limits the life span of normal cells and eventually leads to senescence. To become immortal, human cancers including OCa are invariably associated with activation of mechanism that maintains telomere length. Approximately 85-90% of cancers show reactivation of telomerase. The present study shows that telomerase in OCa cells is down-regulated by 1,25(OH)2VD3. Down-regulation of telomerase is due to decreased stability of hTERT mRNA rather than VDRE-mediated transcriptional repression through the putative VDRE present in the regulatory region of the hTERT gene. It is known that the inhibition of telomerase may lead to a phenotypic lag during which cells would continue to divide until the point at which the telomeres became critically short. This phenomenon may explain why the apoptotic induction by 1,25(OH)2VD3 needs the treatment for more than 6 days. As mentioned in the results, no detectable shortening of telomeric repeats was observed in parental OVCAR3 cells after 9 days of treatment with 1,25(OH)2VD3 (Fig. 4D). This is likely due to the fact that the short telomere (about 3 kb) in OVCAR3 cells is very close to the minimal length required for survival and that cells with detectably shorter telomere may have been selected against apoptosis. It has been shown that transformed human cells enter crisis once the terminal restriction fragment of the telomere reaches a length of about 4 kb. This is insufficient to protect chro

Dogs Can Smell Cancer? - 0 views

  •  
    Dogs can help doctors "smell" cancer? It may sound incredible, but in fact, this research has made great progress. Recently, the "Cancer Sniffing Dogs Project", approved by the British NHS, has entered the testing phase. Milton Keynes University Hospital of Buckinghamshire also approved this research program proposed by a charity organization.

ScienceDaily: Vitamin D Inhibits Progression Of Some Prostate Cancers - 0 views

  •  
    ScienceDaily (Feb. 8, 2006) - Vitamin D can inhibit the spread of prostate cancer cells by limiting the activity of two specific enzymes, University of Rochester Medical Center scientists report. \n\nThe finding means that vitamin D could provide beneficial treatment to prostate cancer patients with high levels of the enzymes, the scientists said.\n
