A Urine Test for Kidney Cancer Advances

Share this content:

Syndicated medical journalist John Schieszer reports that researchers at the Washington University School of Medicine in Saint Louis have identified a pair of proteins excreted in the urine that could lead to earlier and more accurate diagnosis of kidney cancer. The proteins occurred in large quantities in urine specimens from kidney cancer patients but were not elevated in healthy individuals or in patients without cancer who were scheduled for surgery. In addition, when the kidney tumors were removed, levels of the proteins urine dropped precipitously.
