Whole Health Source: Cancer and the Immune System - 0 views

  •  
    They found some important trends. Granulocytes from people over 50 years old had a reduced ability to kill cancer cells, as did granulocytes from people with cancer. This raises the possibility that cancer is not simply the result of getting too old, but a very specific weakening of the immune system. The most important finding, however, was that the granulocytes' kung-fu grip declined dramatically during the winter months. Here's Dr. Cui: Nobody seems to have any cancer-killing ability during the winter months from November to April.

    "Cancer lies dormant in all of us," he wrote in his new book, "Anticancer: A New Way of Life" (Viking, $25.95). "But our bodies are also equipped with a number of mechanisms that detect and keep such (defective) cells in check." Cancer rears its ugly head when things get out of balance, Servan-Schreiber said in an interview. And that can happen if the bad guys that promote the growth of cancer cells (tobacco, excessive alcohol, excessive sugar, hydrogenated fats, environmental pollutants) outnumber the good guys that support our natural defenses (cancer-fighting phytochemicals found in fruits, vegetables, herbs and teas; physical activity; and stress management techniques). But conventional treatment, while indispensable, focuses on a single target: destroying cancer cells. Doctors rarely address the other side: teaching patients how to fortify themselves using nutrition, exercise and stress-management techniques to create an inhospitable environment for cancer.

Head And Neck Cancer Survivors Who Use Alcohol And Cigarettes Have Increased Death Risk - 0 views

  •  
    "Cigarette smoking and alcohol consumption before head and neck cancer diagnosis strongly predicts the patient's future risk of death, according to published studies. Now, results of a new study show a similar effect among those who continued these habits after cancer diagnosis. "Most cancer survivors are counseled to quit smoking; despite this, many still smoke. In our study, 21 percent continued to smoke even after their cancer diagnosis, increasing their risk of death," said researcher Susan T. Mayne, Ph.D. "Similarly, we found that continued drinking increases the risk of death.""

    Serum 25-hydroxyvitamin D and colon cancer: eight-year prospective study. Garland CF, Comstock GW, Garland FC, Helsing KJ, Shaw EK, Gorham ED. Lancet. 1989 Nov 18;2(8673):1176-8. PMID: 2572900 Blood samples taken in 1974 in Washington County, Maryland, from 25 620 volunteers were used to investigate the relation of serum 25-hydroxyvitamin D (25-OHD) with subsequent risk of getting colon cancer. 34 cases of colon cancer diagnosed between August, 1975, and January, 1983, were matched to 67 controls by age, race, sex, and month blood was taken. Risk of colon cancer was reduced by 75% in the third quintile (27-32 ng/ml) and by 80% in the fourth quintile (33-41 ng/ml) of serum 25-OHD. Risk of getting colon cancer decreased three-fold in people with a serum 25-OHD concentration of 20 ng/ml or more. The results are consistent with a protective effect of serum 25-OHD on colon cancer.

    Are sunlight deprivation and influenza epidemics associated with the onset of acute leukemia? Timonen T, Näyhä S, Koskela T, Pukkala E. Haematologica. 2007 Nov;92(11):1553-6. PMID: 18024404 doi:10.3324/haematol.10799 Month of diagnosis of 7,423 cases of acute leukemia (AL) in Finland during 1964-2003 were linked with data on influenza and solar radiation. Acute myeloblastic leukemia (AML) showed the highest risk in the dark season. During the light season, the incidence decreased by 58% (95% confidence interval, 16-79%) per 1,000 kJ/m2/d increase of solar radiation. Independent of solar radiation, AML increased by 9% (95% confidence interval, 0-19%) during influenza epidemics. Reoccurring at the same time annually, darkness-related vitamin D deficiency and influenza could cause successive and co-operative mutations leading to AL with a short latency.

    Vitamin D status and the risk of lung cancer: a cohort study in Finland. Kilkkinen A, Knekt P, Heliövaara M, Rissanen H, Marniemi J, Hakulinen T, Aromaa A. Cancer Epidemiol Biomarkers Prev. 2008 Nov;17(11):3274-8. PMID: 18990771v In conclusion, although there was no overall association between vitamin D and lung cancer risk, women and young participants with a higher level of vitamin D were observed to have a lower lung cancer risk. Although experimental data support the suppressing effect of vitamin D on the development of lung cancer, large epidemiologic studies from different populations with repeated measurements of vitamin D are warranted to confirm this finding.

    Inverse association between serum 25(OH) vitamin D levels and non-melanoma skin cancer in elderly men.

[Epub ahead of print] PMID: 19921445 Our results suggest that a diagnosis of NMSC is not a surrogate for adequate 25(OH)D levels or increased UV exposure, and high 25(OH)D levels may be associated with a reduced risk of NMSC.

    A phase 2 trial exploring the effects of high-dose (10,000 IU/day) vitamin D(3) in breast cancer patients with bone metastases. Amir E, Simmons CE, Freedman OC, Dranitsaris G, Cole DE, Vieth R, Ooi WS, Clemons M. Cancer. 2009 Nov 13. [Epub ahead of print] PMID: 19918922 DOI: 10.1002/cncr.24749 METHODS: Patients with bone metastases treated with bisphosphonates were enrolled into this single-arm phase 2 study. Patients received 10,000 IU of vitamin D3 and 1000 mg of calcium supplementation each day for 4 months. The effect of this treatment on palliation, bone resorption markers, calcium metabolism, and toxicity were evaluated at baseline and monthly thereafter. CONCLUSIONS: Daily doses of 10,000 IU vitamin D3 for 4 months appear safe in patients without comorbid conditions causing hypersensitivity to vitamin D. Treatment reduced inappropriately elevated parathyroid hormone levels, presumably caused by long-term bisphosphonate use. There did not appear to be a significant palliative benefit nor any significant change in bone resorption. Cancer 2010. © 2009 American Cancer Society.

    Mitochondrially targeted effects of berberine [Natural Yellow 18, 5,6-dihydro-9,10-dimethoxybenzo(g)-1,3-benzodioxolo(5,6-a) quinolizinium] on K1735-M2 mouse melanoma cells: comparison with direct effects on isolated mitochondrial fractions. Pereira GC, Branco AF, Matos JA, Pereira SL, Parke D, Perkins EL, Serafim TL, Sardão VA, Santos MS, Moreno AJ, Holy J, Oliveira PJ. J Pharmacol Exp Ther. 2007 Nov;323(2):636-49. Epub 2007 Aug 17. PMID: 17704354 doi: 10.1124/jpet.107.128017 The present work shows that berberine is accumulated by mitochondria of a mouse melanoma cell line, leading to mitochondrial fragmentation and dysfunction, accompanied by decreased cellular energy charge. When the effect was compared with the results obtained on isolated mitochondrial fractions, it is observed that regardless of the system used, berberine is toxic for mitochondria. One major limitation of the present study (as in many others) is the lack of knowledge of the real concentration of berberine that reaches mitochondria in intact cells. Although we do not possess data regarding this aspect, it is wise to speculate that mitochondrial berberine concentrations will be much higher than in the bulk cytosol due to electrophoretic accumulation. We believe that the range of berberine concentrations accumulated by mitochondria in intact cells is within the range of concentrations used on isolated mitochondrial fractions in the present study. The present work not only provides insights on the mechanism by which berberine interferes with tumor cell proliferation, demonstrating previously unknown effects on mitochondrial physiology, but also raises a note of caution on the use of berberine as a nontoxic "natural" over-the-counter medication.
