We propose the following two aims: 1. Determine the performance of using urinary glycoproteomics and mass spectrometry for the detection of aggressive prostate cancer. We will (a) validate 4 candidate glycoproteins to detect AG PCa in diagnostic biopsy in the NCI-EDRNs Urinary PCA3 Evaluation Trial: (b) with PCA3 trial samples further develop a glycoproteomic risk score for predicting AG Pca in diagnostic biopsy; (c) validate the utility of glycoproteins separately and in combination to predict prostate cancer with a higher tumor grade (i.e., Gleason 3+4 or greater) at radical prostatectomy with NCI-EDRN Tissue Upgrading cohort. 2. Develop and apply ELISA assays to verify the candidate glycoproteins as non-invasive urinary tests for detecting aggressive prostate cancer.
