Background: Loss of the membrane endopeptidase CD10 plays an important role in the development of neuropeptide-mediated androgen-independent prostate cancer cell growth. The aim of this study was to investigate the potential prognostic value of the CD10/neuropeptide axis with regard to prostate-specific antigen (PSA) failure after radical prostatectomy (RP) in early prostate cancer (PC) patients.

Methods: Tumor samples from 70 early PC patients who underwent RP were immunohistochemically evaluated for expression of CD10 and endothelin-1 (ET-1). The examined parameters were prospectively correlated with time to PSA failure and combined with Gleason grade and pathological TNM stage.

Results: Membranous and apical cytoplasmic expression of CD10 was directly correlated with time to PSA failure ( P < 0.001). Cytoplasmic ET-1 was inversely correlated with time to PSA relapse ( P = 0.002). CD10 and ET-1 were inversely interrelated ( P < 0.001). CD10 expression (P = 0.012) and stage ( P = 0.013) were independent predictors of biochemical recurrence.

Conclusion: CD10 and ET-1 follow inverse patterns of expression in tumors of early PC patients, in accordance with their biological roles and molecular interrelations. Evaluation of CD10 expression in early PC might contribute to a better prediction of PSA relapse-free survival after RP.
