Clinical Utility of Urinary CD90 as a Biomarker for Prostate Cancer Detection
Tumor-associated stromal cells differ from normal gland-associated stromal cells in gene expression. Genes up-regulated in these stromal cells are potential cancer biomarkers, especially those encoding secreted or extracellular proteins. These proteins might be detected in urine. CD90/THY1 is one such candidate. A clinical test based on urinary CD90 would be useful in reducing the number of unnecessary biopsies done because of abnormal serum PSA and/or DRE finding. Elevated CD90 protein is found in tumor tissue and urine.
There are currently no biomarkers annotated for this protocol.
