Biomarker identifies fatal prostate cancer
WINSTON-SALEM, N.C. (UPI) -- U.S. researchers have identified an accurate biomarker for fatal prostate cancer -- high levels of ionized serum calcium.
The study, published in Cancer Epidemiology, Biomarkers & Prevention, confirmed earlier findings that men who have too much calcium in their bloodstreams subsequently have an increased risk of fatal prostate cancer.
"Scientists have known for many years that most prostate cancers are slow-growing and that many men will die with, rather than of, their prostate cancer," senior author Gary G. Schwartz of Wake Forest University Baptist Medical Center said in a statement. "Many men with this diagnosis are treated unnecessarily."
The researchers found that men in the highest one-third of ionized serum calcium levels are three times more likely to die of prostate cancer than those with the least amount of ionized serum calcium.
Schwartz said the research is focused on identifying characteristics of the men who will develop the tumors before they develop. However, he cautioned that calcium in serum is little influenced by calcium in the diet. Serum calcium levels are controlled genetically and are stable over much of an individual's life, he said.
"These results do not imply that men need to quit drinking milk or avoid calcium in their diets," Schwartz added.

Nuevas pruebas indican que los niveles séricos elevados de calcio iónico puede predecir el riesgo de muerte por cáncer de próstata. Si se verifica en el futuro, los estudios prospectivos, los niveles de calcio ionizado en el suero podría ayudar a los médicos y pacientes en la toma de decisiones sobre el tratamiento.
En un análisis previo de los datos de la National Health and Nutrition Examination Survey (NHANES I) estudio, el Dr. G. Halcyon Skinner, de la Universidad de Wisconsin-Madison, y el Dr. Gary G.

New Biomarker For Fatal Prostate Cancer Found
New research findings out of Wake Forest University School of Medicine and the University of Wisconsin may help provide some direction for men diagnosed with prostate cancer about whether their cancer is likely to be life-threatening.
In a study that appears in the February issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, researchers confirmed their earlier findings that men who have too much calcium in their bloodstreams subsequently have an increased risk of fatal prostate cancer. Now researchers have also identified an even more accurate Generic Viagra of the fatal cancer: high levels of ionized serum calcium.
"Scientists have known for many years that most prostate cancers are slow-growing and that many men will die with, rather than of, their prostate cancer," said Gary G. Schwartz, Ph.D., senior author of the study and an associate professor of cancer biology at the School of Medicine, a part of Wake Forest University Baptist Medical Center. "The problem is, how can we determine which cancers pose a significant threat to life and need aggressive treatment versus those that, if left alone, are unlikely to threaten the patient's life? These findings may shed light on that problem."
