Aim: A higher Gleason score was associated with a lower tumor urotensin II receptor (UTII-R) expression in prostate cancer patients. Methods: A retrospective review of formalin-fixed paraffin-embedded tumor tissue derived from those who had prostatectomy and matching biopsy specimens was conducted at six Institutions. UTII-R expression was evaluated on biopsy by immunohistochemistry. Results: A total of 58 subjects undergoing radical prostatectomy were included. At multivariate analysis, low UTII-R expression was a significant predictor of Gleason upgrading, with an odds ratio of 10.3 (95% CI: 1.55–68.4), and of pathology upstaging, with an odds ratio of 11.1 (95% CI: 1.23–100.48). Conclusions: UTII-R expression on biopsy was associated with Gleason upgrading and pathology upstaging in prostate cancer patients.
