ScienceDaily (Dec. 25, 2007) - Researchers from the Universities of Warwick, Edinburgh, Dundee and the Czech Republic's Institute of Biophysics have discovered a new light-activated platinum-based compound that is up to 80 times more powerful than other platinum-based anti-cancer drugs and which can use "light activation" to kill cancer cells in much more targeted way than similar treatment

T-helper/T-regulator lymphocyte ratio as a new immunobiological index to quantify the anticancer immune status in cancer patients. Brivio F, Fumagalli L, Parolini D, Messina G, Rovelli F, Rescaldani R, Vigore L, Vezzo R, Vaghi M, Di Bella S, Lissoni P. In Vivo. 2008 Sep-Oct;22(5):647-50. PMID: 18853761 RESULTS: The mean TH/TR ratio observed in patients with metasytases was significantly lower with respect to that found in both patients without metastases and controls. On the contrary, the absolute mean number of T-reg cells was higher in patients with metastases than in those without, but the difference was not statistically significant. CONCLUSION: The evaluation of T-reg cells in terms of their proportion with respect to T-helper cell total number seems to be more appropriate than the simple measurement of their absolute count, in order to quantify cancer-related immunosuppression. Thus, the TH/TR ratio could represent a useful biological marker to explore the immune status of cancer patients.

A large number of new vitamin D studies have appeared in the scientific literature since I wrote my plea to the federal government. These studies don't just confirm what we knew 16 months ago-they show that optimizing vitamin D intake will save even more lives than what we projected. Vitamin D More Effective Than Previously Known For instance, a study published in June 2008 showed that men with low vitamin D levels suffer 2.42 times more heart attacks. Now look what this means in actual body counts.

Women who are vitamin D deficient when they are diagnosed with breast cancer are more likely to have their disease spread and are more likely to die than women who have adequate vitamin D levels, new Canadian research says. The study found that women who were vitamin D deficient were 94 per cent more likely to have their cancer metastasize (spread) and 73 per cent more likely to die. The research was led by Dr. Pamela Goodwin, a breast cancer researcher at Mount Sinai Hospital in Toronto. The study analyzed blood samples and disease outcome from more than 500 women diagnosed with breast cancer between 1989 and 1995. Women were followed up for an average of 11 years.

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

"For years, it's been the perfect excuse for secret admirers to steal a kiss with the object of their desire. But research suggests mistletoe could do much more than just ignite Christmas passions. Scientists have found an extract of the plant could help to fight bowel cancer, which affects 37,500 a year in the UK. Patients who had the mistletoe treatment regularly injected into their blood had fewer side-effects from toxic chemotherapy and radiotherapy and survived longer than those who did not. The extract is thought to help the body's immune system fight tumours and speed up the disposal of toxic 'debris' left by chemotherapy. Researchers led by Professor Kurt Zanker from the German Institute of Immunology and Experimental Oncology, concluded: 'The results suggest convincing evidence that there is a significant benefit from treatment with mistletoe extract.' The scientists treated 429 cancer patients with the mistletoe jab and compared them with 375 receiving conventional care. The results, published in the journal of The Society For Integrative Oncology, showed only 19 per cent of those in the mistletoe group suffered side-effects from toxic treatments, compared to 48 per cent in the other group. They were also 32 per cent more likely to still be alive five years after starting therapy."

Patients with larynx cancer who received a three-drug combination of docetaxel, cisplatin and 5-fluorouracil (TPF) during induction chemotherapy were more likely to retain larynx function than were patients treated with cisplatin and 5-fluoruracil (PF) alone, according to data from a randomized controlled trial in the March 24 online issue of the Journal of the National Cancer Institute.

Mushrooms could give the immune system a hand in attacking foreign invaders, if the effects in mice translate to humans.\n\nWhat's more, the common white button mushroom had stronger immune-boosting effects than more exotic -- and more expensive -- fungi such as oyster and shiitake mushrooms, Dr. Keith Martin of Arizona State University in Mesa and his colleagues found

The active compound in marijuana, THC, can slow the growth of lung tumours and reduce the spread of the cancer in mice, a preliminary study reveals. Human lung cancer tumours grew less than half as fast in mice that received moderate doses of the compound, the researchers reveal. They hope that drugs mimicking the apparent anti-cancer effects of tetrahydrocanabinol (THC) could one day help treat patients. The team strongly discourage people from self-medicating by smoking marijuana, noting that doing so could potentially encourage tumour growth.

NEW YORK (Reuters Health) - Women who get plenty of mushrooms and green tea in their diets may have a lower risk of developing breast cancer, new study findings suggest.\n\nThe study, of more than 2,000 Chinese women, found that the more fresh and dried mushrooms the women ate, the lower was their breast cancer risk.

A signalling pathway that influences how sensitive cancer cells are to the beneficial effects of dietary restriction is described in this week's Nature. Dietary restriction - eating less calories while maintaining essential vitamins and minerals - can extend lifespan, and reduce cancer incidence and growth. But some types of cancer cell are more sensitive to the anti-growth effects of dietary restriction than others, Nada Kalaany and David Sabatini report. The effect hinges on the activity of the phosphatidylinositol-3-kinase (PI3K) pathway. If the pathway is active, dietary restriction has no effect on cancer cells. However, if the pathway is inactive, tumours are sensitive to dietary restriction.

ScienceDaily (Mar. 10, 2009) - A study led by researchers at the University of Southern California (USC) found that men who took a daily folic acid supplement of 1 mg daily had more than twice the risk of prostate cancer compared with men who took a placebo.

March 9, 2009 -- Red or white wine with dinner? A new study suggests a woman's wine choice should be based on personal preference rather than any hope that a wine's color may affect its breast cancer-fighting ability. "We found no difference between red or white wine in relation to breast cancer risk. Neither appears to have any benefits," researcher Polly Newcomb, PhD, MPH, head of the Cancer Prevention Program at the Fred Hutchinson Cancer Research Center in Seattle, says in a news release.

The prostate is the gland below a man's bladder that produces fluid for semen. Prostate cancer is the third most common cause of death from cancer in men of all ages. It is rare in men younger than 40. Levels of a substance called prostate specific antigen (PSA) is often high in men with prostate cancer. However, PSA can also be high with other prostate conditions. Since the PSA test became common, most prostate cancers are found before they cause symptoms. Symptoms of prostate cancer may include Problems passing urine, such as pain, difficulty starting or stopping the stream, or dribbling Low back pain Pain with ejaculation Prostate cancer treatment often depends on the stage of the cancer. How fast the cancer grows and how different it is from surrounding tissue helps determine the stage. Treatment may include surgery, radiation therapy, chemotherapy or control of hormones that affect the cancer.
