Could antioxidants speed up cancer progression?

A new Swedish study conducted at the Sahlgrenska Cancer Center at the University of Gothenburg has shown that doses of acetylcysteine, an antioxidant supplement, increased growth of tumours in mice with early lung cancer.  According to senior author Dr. Martin Bergo, "antioxidants caused the mice to die twice as fast, and the effect was dose-dependent."  Although some critics argue that a study involving animals may not translate to producing similar results in humans, Peter Campbell, director of the Tumor Repository at the American Cancer Society points out that trials conducted on humans in the 1980s and 1990s did indicate that antioxidants increased the incidence of lung cancer in smokers.

It’s time to treat smoking as an addiction

The recent 50th anniversary of the landmark U.S. Surgeon-General’s report on smoking provides a good opportunity to reflect on how far we’ve come in the war on tobacco, as well as how far we have left to go. Dr. Andrew Pipe, the chief of the division of prevention and rehabilitation at the Ottawa Heart Institute, says smoking cessation should be promoted as aggressively as blood-pressure control. When someone suffers from hypertension, they are not asked to consider getting their blood pressure down some day, they are prescribed medication, given a follow-up appointment and offered lifestyle counselling. Smoking is much more deadly, but not taken as seriously. Read more here.

Melatonin may lower prostate cancer risk

Higher levels of melatonin, a hormone involved in the sleep-wake cycle, may suggest decreased risk for developing advanced prostate cancer, according to results presented at the AACR-Prostate Cancer Foundation Conference on Advances in Prostate Cancer Research, held Jan. 18-21. "Sleep loss and other factors can influence the amount of melatonin secretion or block it altogether, and health problems associated with low melatonin, disrupted sleep, and/or disruption of the circadian rhythm are broad, including a potential risk factor for cancer," said Sarah C. Markt, M.P.H., doctoral candidate in the Department of Epidemiology at Harvard School of Public Health in Boston. Read more here.

Antipsychotic drug exhibits cancer-fighting properties

In a prime example of finding new uses for older drugs, studies in zebrafish show that a 50-year-old antipsychotic medication called perphenazine can actively combat the cells of a difficult-to-treat form of acute lymphoblastic leukemia (ALL). The drug works by turning on a cancer-suppressing enzyme called PP2A and causing malignant tumor cells to self-destruct. The findings suggest that developing medications that activate PP2A, while avoiding perphenazine's psychotropic effects, could help clinicians make much-needed headway against T-cell ALL, and perhaps other tumors as well.

The increased activation of a key oncogene in head and neck cancers could be the result of mutation and dysfunction of regulatory proteins that are supposed to keep the gene, which has the potential to cause cancer, in check, according to a new study led by researchers at the University of Pittsburgh School of Medicine. The findings suggest a new target for drugs to treat head and neck tumors, as well as other cancers. Read more here.

Cancer prevention guidelines pay off for older women

A study conducted by the U.S. National Institutes of Health on almost 66,000 women between the ages of 50 and 79 indicates that those adhering to the American Cancer Society's Nutrition and Physical Activity Cancer Prevention Guidelines "had a 17% lower risk of cancer, a 20% lower risk of cancer-related death, and a 27% lower risk of death from all causes."  According to study author Cynthia Thomson, professor of public health at the University of Arizona in Tucson, eating a healthy balanced diet, regular exercise, avoiding and/or limiting alcohol and refraining from smoking all contribute to reducing cancer risk.
