Abstract
BACKGROUND: The purpose of this study was to investigate the prognostic value of different forms of the urokinase receptor, uPAR, in serum from prostate cancer (PC) patients. PATIENTS AND METHODS: The uPAR forms were measured in samples from 131 metastatic PC patients. These constituted a subset of patients included in a randomized clinical trial of treatment with total androgen blockade (TAB) versus polyestradiol phosphate (PEP). Pre-treatment serum levels of intact uPAR (uPAR(I-III)), intact plus cleaved uPAR (uPAR(I-III) + uPAR(II-III)) and domain I (uPAR(I)) were measured using time-resolved fluorescence immunoassays (TR-FIAs). RESULTS: High serum levels of each of the uPAR forms were significantly associated with short overall survival (OS). The prognostic impact was strongest in the TAB treated patients with all uPAR forms being statistically significant. In multivariate analysis, uPAR(I-III) + uPAR(II-III) was an independent prognostic factor in TAB treated patients (HR = 5.2, 95% confidence interval (CI): 2.5-10.6, P
