f prostate cancer development among all patients and associated with a two-fold increased risk of developing lethal prostate cancer. IL-6 levels were not associated with prostate cancer risk overall. But when they separated out men by body mass index, those who had a healthy weight and high IL-6 in their blood had a 40 percent higher risk of developing prostate cancer.

Researchers suspect that abnormal amounts of IL-6 and CRP are markers of biological processes involved in development of a number of diseases, including cancer. IL-6 is secreted by immune cells in response to infection or trauma, and it, in turn, stimulates synthesis of CRP in the liver, which is believed to play a role in response to infections and cellular damage control. CRP has been found to be a marker of cardiovascular disease, diabetes and colon cancer, but its use as a cardiology screening test has been controversial.

Stark noted that the predictive power of these two markers for determining prostate cancer risk and mortality needs to be confirmed in other prospective studies. She added, "Understanding the role of inflammation in prostate cancer is important because inflammatory pathways could potentially be targeted for prevention and treatment."

Characteristics Of Long-Term Lung Cancer Survivors

In preliminary findings from an ongoing study, researchers at Mayo Clinic have identified four different factors they say predicts long-term survival in patients diagnosed with lung cancer, and one of the strongest is inheritance of a gene variant, GSTM1 positive, which is more efficient than another allele type of the GSTM1 gene at detoxifying carcinogens.

They found that patients with a null type at this gene were four times more likely to die within two years, as were matched patients who had the positive variant.

The researchers also found that patients who had surgery, who were active, and whose cancer did not come back or progress were
