Diagnostic Test Targets Tumor Source; Stanford University To Study Genomics-Based Diagnostic Test For Uncertain Tumors

PALO ALTO, Calif., May 8 (UPI) -- U.S. researchers are looking at a new genomics-based diagnostic test developed to determine the origins of hard-to-identify tumors. Stanford University School of Medicine is evaluating the Pathwork Tissue of Origin Test, which measures the expression of more than 1,500 genes to compare a tumor's gene expression profile to those of 15 known tissues and provide a probability-based score for each potential tissue, Pathwork Diagnostics Inc. said.
