PSCA expression is associated with favorable tumor features and reduced PSA recurrence in operated prostate cancer.


ABSTRACT: BACKGROUND:Prostate Stem Cell Antigen (PSCA) is frequently expressed in prostate cancer but its exact function is unclear. METHODS:To clarify contradictory findings on the prognostic role of PSCA expression, a tissue microarray containing 13,665 prostate cancers was analyzed by immunohistochemistry. RESULTS:PSCA staining was absent in normal epithelial and stromal cells of the prostate. Membranous and cytoplasmic PSCA staining was seen in 53.7% of 9642 interpretable tumors. Staining was weak in 22.4%, moderate in 24.5% and strong in 6.8% of tumors. PSCA expression was associated with favorable pathological and clinical tumor features: Early pathological tumor stage (p?
