Severe Sleep Problems May Increase Prostate Cancer Risk

Older men who experience severe sleep problems may be at greater risk of prostate cancer, according to a study presented at the Genitourinary Cancers Symposium in San Francisco. Since this was an observational study, the researchers did not explore whether treating sleep problems would help reduce the risk of prostate cancer.

In this new study, the risk of developing prostate cancer was increased by 70% when severe sleep problems were present compared with men who had no sleep disturbances. Some previous studies have indicated that disrupted sleep, which is typical of working the night shift, has an impact on the risk of prostate cancer the longer a man continues such a schedule.

Alpharadin Benefits in Hormone Resistant Prostate Cancer

A novel injectable drug called radium-223 chloride (Alpharadin) improved survival by 30% in men with hormone therapy resistant prostate cancer in a recent clinical trial. Alpharadin also significantly reduced the men’s risk of bone fracture and spinal cord compression, as well as the need for external beam radiation.

These trial results were reported at a press briefing prior to their presentation at the Genitourinary Cancers Symposium in New Orleans and should be considered preliminary until they are published in a peer-reviewed journal. However, according to a statement by A. Oliver Sartor, MD, of Tulane University, “we believe this novel alpha-pharmaceutical…may provide a new standard of care for the treatment of patients with bone metastases in advanced prostate cancer.”

Vigorous Exercise Lowers Risk of Prostate Cancer Progression

Scientists at the University of California, San Francisco (UCSF) believe they have discovered why vigorous exercise lowers the risk of prostate cancer progression. While previous studies have indicated that vigorous exercise is associated with a lower risk of prostate cancer progression, they did not identify why this benefit occurred. Now, a research team has identified the molecular profile of 184 genes in the healthy prostate tissue of men with low-grade prostate cancer that are linked to vigorous exercise.

According to June Chan, ScD, the Steven and Christine Burd-Safeway Distinguished Professor at UCSF, understanding how vigorous exercise has an effect on these genes that leads to a reduced risk of prostate cancer progression may help uncover new ways to manage the disease.

Study Questions Proton Therapy for Prostate Cancer

A warning to men considering a pricey new treatment for prostate cancer called proton therapy: Research suggests it might have more side effects than traditional radiation does.

A study of Medicare records found that men treated with proton beams later had one-third more bowel problems, such as bleeding and blockages, than similar men given conventional radiation.

This is an observational study so it is not definitive, but it is one of the largest to compare these treatments. Proton therapy is rapidly growing in use — Medicare covers it — even though no rigorous studies have tested whether it is as safe or effective as usual care.

Vitamin D Linked to Lower Risk of Colorectal Cancer

High levels of vitamin D in the bloodstream has been linked to a lower risk of colorectal cancer. Among the findings in the new study was the observation that vitamin D levels interacted with specific areas of the vitamin D receptor gene, with increased vitamin D levels linked to even greater reductions in the risk of colorectal cancer.

Green Tea Helps Prevent Prostate Cancer in Men with High-Grade PIN

Men with high-grade PIN (prostate intraepithelial neoplasia) are at significant risk of developing prostate cancer within one year of undergoing a repeat prostate biopsy. It may be possible to safely and effectively reduce the risk of prostate cancer by taking green tea catechins, according to a study published in Cancer Research. Read more

Is Incontinence/Overactive Bladder Over-Treated?

Two Finnish experts have questioned the idea of the ‘overactive bladder syndrome’. According to them, this syndrome is mostly beneficial to those with commercial interests, while from the patient perspective and for the development of treatments, it may be detrimental.

“The overactive bladder syndrome has become an accepted way to simplify a complex array of symptoms and leads people to believe that an overactive bladder is an independent disease in itself. However, the truth is not as simple as this, as there are usually several factors at work explaining the symptoms. This is also one of the reasons why so called overactive bladder medications often do not bring the hoped result,” says Kari Tikkinen, MD, PhD, from the HUCS Department of Urology.
