Guidelines for Prostate Screening Widely Ignored, Study Finds

2008 recommendations from federal task force had no impact

New research confirms that the controversial decision by Warren Buffett – the 81-year-old CEO of Berkshire Hathaway – to undergo a blood test screening for prostate cancer despite his age is hardly unusual. Despite recommendations in 2008 from the United States Preventive Services Task Force against testing for prostate cancer in men aged 75 years or older, almost half of men in that age group continue to get screening tests.

In 2005, before the recommendations were released, 43 percent of men age 75 and above elected to take the prostate-specific antigen (PSA) test. In August 2008, the Task Force stated it “recommends against the service,” arguing “there is moderate or high certainty the service has no net benefit or that the harms outweigh the benefits.” (more…)

TORONTO, ON — Low oxygen levels in tumors can be used to predict cancer recurrence in men with intermediate-risk prostate cancer even before they receive radiation therapy. (more…)

Researchers Develop System that Finds Prostate Cancer Metastases Earlier

Researchers at UCLA’s Jonsson Comprehensive Cancer Center have developed a way to image the spread of a dangerous form of prostate cancer earlier than today’s conventional imaging techniques. The new method may allow oncologists to find and treat metastases more quickly and give patients a better chance at survival.

The gene-based imaging system targets castration-resistant prostate cancer, an aggressive form of the disease that has become resistant to the hormone treatment known as androgen-deprivation therapy. Once this treatment no longer works, the cancer will progress within 12 to 18 months, and the prognosis becomes grim, said senior study author Dr. Lily Wu, a professor of molecular and medical pharmacology and a Jonsson Cancer Center researcher.

A protein that is crucial for regulating the self-renewal of normal prostate stem cells, which are needed to repair injured cells or restore normal cells killed by hormone-withdrawal therapy for cancer, also aids the transformation of healthy cells into prostate cancer cells, researchers at UCLA have found.

The findings, by scientists with the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, may have important implications for controlling cancer growth and progression.

Results from the three-year study, done in primary cells and in animal models, were published Dec. 2 in the early online edition of the peer-reviewed journal Cell Stem Cell.

The protein, called Bmi-1, is often up-regulated, or turned on, in prostate cancer. It has been associated with higher-grade cancers and is predictive of poor prognosis, according to previous studies. However, its functional roles in prostate stem cell maintenance and prostate cancer have been unclear, said the study’s senior author, Dr. Owen Witte, director of the Broad Stem Cell Research Center and a Howard Hughes Medical Institute investigator.

*Researchers urge appropriate use of androgen deprivation therapy*

ANN ARBOR, Mich. — Men treated with hormone-based therapy for prostate cancer faced a 30 percent to 40 percent higher risk of colorectal cancer, compared to patients who did not receive this treatment, according to a new study.

The study looked at use of androgen deprivation therapy, a common type of treatment for prostate cancer that involves blocking the male hormone testosterone through either surgical removal of the testicles or a series of injections. It’s been shown to benefit men with advanced cancers, but its benefit for less-advanced disease is unclear. Still, more than half a million men in the United States currently receive this therapy.

Health benefits of walnuts have been known since time immemorial. Hippocrates and Avicenna mentioned them in the treatment of various diseases. In addition, the ancients thought that they stimulate mental activity. Anna Protsenko, a nutritionist, told MedPulse.ru.

“Walnuts contain a great deal of minerals,” the expert explains. “They include iron, copper, cobalt, potassium, sodium, phosphorus, magnesium, calcium, and iodine. Many of them are antioxidants.
