  1. Metformin breast cancer


    Metformin is a lipophilic biguanide which inhibits hepatic gluconeogenesis and improves peripheral utilization of glucose. It is the first line pharmacotherapy for glucose control in patients with Type 2 diabetes due to its safety, efficacy and tolerability. Metformin exhibits pleotropic effects, which may have beneficial effects on a variety of tissues independent of glucose control. A potential anti-tumourigenic effect of metformin may be mediated by its role in activating AMP-kinase, which in turn inhibits mammalian target of rapamycin (m TOR). Non-AMPK dependent protective pathways may include reduction of insulin, insulin-like growth factor-1, leptin, inflammatory pathways and potentiation of adiponectin, all of which may have a role in tumourigenesis. A role in inhibiting cancer stem cells is also postulated. A number of large scale observational and cohort studies suggest metformin is associated with a reduced risk of a number of cancers, although the data is not conclusive. The research, published online June 11 in the Journal of Clinical Oncology, echoes other recent studies that have suggested the diabetes drug may help cut the chances of prostate, pancreatic, liver and oral cancer, as well as certain forms of melanoma. The researchers found that the incidence of invasive breast cancer was 25 percent lower in women with diabetes who were taking metformin than it was in women who weren't taking the drug. Between 90 percent and 95 percent of these cases are type 2 diabetes, in which the body's ability to make and use insulin deteriorates. Approximately 25.8 million people in the United States have diabetes, according to the U. "Type 2 diabetes is a disease of insulin resistance," said study co-author Dr. Rowan Chlebowski, a medical oncologist with the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center, in Torrance, Calif. Insulin is a hormone that helps regulate the level of glucose (sugar) in the body. With type 2 diabetes, the body manufactures larger quantities of insulin to maintain normal levels of glucose in the blood. Metformin, commonly used to treat type 2 diabetes, increases insulin sensitivity and improves the control of blood sugar.

    The Oncology Association of Naturopathic Physicians (Onc ANP) annual conference was chock-full of excellent talks on the use of a variety of supplements that may be useful in helping to reduce the risk of cancer development, progression and recurrence. The talk on metformin was given by Dr Davis Lamson, MS, ND (Tahoma Clinic and Bastyr University.) He made a compelling case for why this commonly prescribed, inexpensive (and safe) diabetes medication might want to be added to the care plan for patients with any one of a variety of cancer types. First of all, metformin has been used for over 50 years in the management of diabetes. It is also available as a generic prescription, so it’s relatively cheap. The challenge for many patients who might want to use it is that most physicians will not write a prescription for it unless you have diabetes (as metformin is only approved by the FDA for this indication.) You might ask your physician to read this article to help convince them to prescribe it to you. (see our blog post on this here.) So, if you reduce the amount of sugar available to feed cancer cells you will significantly slow their growth. Metformin reduces blood sugar through a few different mechanisms: 1) decreasing the amount of sugar made by the liver, 2) reduces the absorption of sugar from the intestines, 3) increases insulin uptake into healthy cells (decreasing sugar in the blood.)One of the most compelling studies that I have seen on the use of metformin’s anti-cancer activity comes from an analysis of 8,000 patients with type 2 diabetes who were followed for 10 years. The researcher found that there was a Metformin is a promising plant-derived compound that has significant anti-cancer activity (reducing the risk of cancer development, cancer recurrence and progression) for many cancer types. Participants included women aged 40 to 65 from Damanhour Oncology Center (Damanhour, Egypt) with newly diagnosed breast cancer. After applying exclusion criteria, a total of 129 nondiabetic women were randomized into 2 main groups—a control group (n=61) who followed adjuvant therapy alone (chemotherapy treatment [CT] and hormonal therapy [HT]) and a metformin group (n=68) who followed adjuvant therapy plus metformin therapy. Following the initial CT, women in the control group with estrogen receptor (ER)-positive breast cancer received tamoxifen, while women in the metformin group with ER-positive breast cancer received both tamoxifen and metformin. Women with ER-negative breast cancer in both control and metformin groups were only treated with CT. A total of 102 women completed the 12-month treatment regimen, with an equal number (n=51) in each group. In the control group, 43 ER-positive women received tamoxifen, and 8 (ER-negative) received only CT; in the metformin group, 42 ER-positive women received tamoxifen plus metformin and 9 (ER- negative) received only metformin in addition to the first round of CT. The women in the metformin group received 850 mg of metformin twice daily.

    If you’re looking for a less costly Viagra, you might want to ask your doctor about sildenafil. It's the active ingredient in both branded Viagra and the drug Revatio, which is a lower dose than Viagra and approved to treat pulmonary arterial hypertension. The important difference: Generic Revatio is available for a fraction of the cost. "Generic Revatio is considerably less expensive, and it is the same drug as Viagra with the same safety and effectiveness," says Bradley Anawalt, M. D., an endocrinologist and professor of medicine at the University of Washington in Seattle who chairs the Endocrine Society's Hormone Health Network. At a lower dose, sildenafil is approved to treat pulmonary arterial hypertension—the higher dose is reserved for treating erectile dysfunction (ED). Anawalt explains that there's a chance your insurance might not cover it to treat ED.
