    Metformin for cancer


    At the recently concluded annual meeting of the American Society of Clinical Oncology (ASCO) a group of researchers from Mexico City described a surprising discovery: In a phase 2 trial in patients with stage 4 lung cancer, a 24-year-old diabetes drug significantly improved survival when added to a standard therapy. That drug, metformin, is used to lower blood sugar in type 2 diabetics. And because it went generic years ago, it generally costs pennies a pill—an advantage that’s enticing to the oncology community, which has been grappling with questions about how to pay for new and very expensive therapies like mutation-targeting and checkpoint-blocking drugs. The notion that metformin may be useful in cancer care isn’t new. In the mid-2000s, several observational studies revealed that the rate of cancer was lower overall in diabetes patients who were taking metformin, and diabetics who did develop cancer while on metformin were less likely to die of the disease than those not taking the drug. So scientists all over the world started studying metformin in various cancers, searching for clues to its cancer-fighting prowess and evidence that it might improve survival when added to traditional treatments. This year’s ASCO featured 15 completed or planned studies of metformin in cancer care. Summary: Studies show that the diabetes drug metformin reduces cancer rates by about a third. The drug is thought to ward off cancer by reducing blood sugar. Researchers are now conducting clinical trials of metformin on healthy senior adults. ] Can a generic medicine costing 5 cents prevent cancer? [This article first appeared on the Longevity website. A growing body of evidence supports the idea that metformin prevents cancer. Sugar feeds cancer cells, and because the diabetes drug reduces blood sugar, then metformin reduces cancer. Metformin was first approved for treating type 2 diabetes in France in 1957, the United Kingdom in 1958, and Canada in 1972, and by the FDA in 1994 Since then, metformin has become the drug of choice in treating type 2 diabetes. The drug is widely expected to be used to fight the upcoming surge in type 2 diabetes. In some countries, metformin is fully approved as a prediabetes treatment, to prevent the onset of type 2 diabetes. In the United States, the FDA allows off-label use for this purpose.

In the early 2000s diabetologists began reporting an unusually low rate of cancer among their patients who were treated with metformin.

    With commentary by Nir Barzilai, MD, director of the Institute for Aging Research, Albert Einstein College of Medicine, and Brian Kennedy, Ph D, president and CEO of the Buck Institute for Research on Aging. Metformin, a drug taken by many with diabetes, may have much greater potential beyond controlling blood sugar, some experts say. And accumulating data suggests that ''it interferes with the biology of aging." Aging, he says, is a primary risk factor for not only diabetes but also most of our big killers, such as Alzheimer's, heart disease and cancer. Metformin may influence fundamental aging factors that underlie many age-related conditions, including cancer, heart disease and Alzheimer's, says Nir Barzilai, MD, director of the Institute for Aging Research at Albert Einstein College of Medicine, the Bronx. In animal and human studies, metformin has shown promise in slowing the aging process and halting diseases. Barzilai plans to launch a large-scale study, Targeting Aging with METformin (TAME), to look at the effects of metformin compared to placebo. His team has already completed the MILES study, Metformin in Longevity, and are analyzing the results. In that study, they gave some participants metformin, at 1,700 milligrams a day, and others placebo. He brushed them off, saying the people who don't see the value of the research ''don't understand the biology of aging and that it can be changed." He doesn't see the research as testing an anti-aging drug. The aim was to see if the metformin could restore the gene expression profile of an older person with blood sugar problems known as impaired glucose tolerance (but not yet diabetic), to that of a younger person. "Aging is not a disease and we don't want it to be a disease," he says. However, age is a risk factor for many disabling conditions, he says.

Chambers Biomedical/Biotechnology Research Institute, Department of Biological and Biomedical Sciences, North Carolina Central University, North Carolina Research Campus, Kannapolis, NC 28081, USA Metformin, a first line medication for type II diabetes, initially entered the spotlight as a promising anti-cancer agent due to epidemiologic reports that found reduced cancer risk and improved clinical outcomes in diabetic patients taking metformin. To uncover the anti-cancer mechanisms of metformin, preclinical studies determined that metformin impairs cellular metabolism and suppresses oncogenic signaling pathways, including receptor tyrosine kinase, PI3K/Akt, and m TOR pathways. Recently, the anti-cancer potential of metformin has gained increasing interest due to its inhibitory effects on cancer stem cells (CSCs), which are associated with tumor metastasis, drug resistance, and relapse. Studies using various cancer models, including breast, pancreatic, prostate, and colon, have demonstrated the potency of metformin in attenuating CSCs through the targeting of specific pathways involved in cell differentiation, renewal, metastasis, and metabolism. In this review, we provide a comprehensive overview of the anti-cancer actions and mechanisms of metformin, including the regulation of CSCs and related pathways. We also discuss the potential anti-cancer applications of metformin as mono- or combination therapies.

    Steroids are hormonal substances that are produced naturally in the body by the adrenal glands (which are just above each kidney) and by the reproductive organs. There are many different types of steroids and they have different effects on the body. These are different to the anabolic steroids used by athletes to enhance their performance. , dexamethasone, fludrocortisone, and occasionally methylprednisolone. Steroids are usually given by mouth in the form of tablets or soluble tablets. They may also be given into a vein (intravenously or IV) through a cannula, central venous catheter or implantable port. If your child is given a short course of steroids, they are unlikely to suffer many side effects. These effects are temporary and will stop when the course of steroids has finished. You may notice that your child becomes irritable and has mood swings. Short-term oral corticosteroid use common, but may pose risks ACP.
