1) MRI or Ultrasound-Guided Biopsies; 2) Effect of Diet on Prostate Cancer; and, 3) Two Genes Linked to Aggressive Prostate Cancer.

1) A recent article was published from the Washington University School of Medicine which compared the results of prostate cancer biopsies as guided by magnetic resonance imaging (MRI) with those obtained via ultrasound guidance. It was concluded that MRI-guided biopsies were more likely to find aggressive tumors than those that rely on ultrasound. For specific details, see the following link.

2) Another article published in Medline Plus, described a Duke University study of the effects of diet and lifestyle on prostate cancer. A diet rich in complex carbohydrates and lower in protein and fat is associated with a 60 percent to 70 percent reduced risk of prostate cancer according to the researchers. In addition, a fiber-filled diet reduced the risk of aggressive prostate cancer by 70 percent to 80 percent. The presence of metabolic syndrome factors also increased the cancer risk. Metabolic syndrome consists of a group of risk factors that increase a person’s risk of heart disease, diabetes and stroke. They include obesity, high blood pressure, elevated blood sugar levels, elevated levels of triglycerides (blood fats) and reduced levels of “good” HDL cholesterol.

3) Lastly, Columbia University researchers have identified two genes that they claim “are likely driving the most aggressive cases of prostate cancer. Other scientists had linked the genes, FOXM1 and CENPF, to cancer, but had not connected them to prostate growths. And more importantly, it was observed that the two genes’ cancer-causing effects only occurred if they are turned on at the same time. These two genes individually don’t do anything, or very little, but only when they are co-active do they produce aggressive forms of the disease.”  The presence of activity in these two genes could be determined at the time of a biopsy.  “If both genes are turned on and highly active, then men would be advised to get immediate treatment such as surgery, radiation or tumor-targeting drugs, or some combination of these. If neither gene, or only one is active, then doctors might recommend less intensive therapy while they monitored the tumors” according to the researchers.
