Prostate Cancer Gene Expression Changes after Treatment with Neoadjuvant Dutasteride

ABSTRACT: To identify molecular changes underlying the chemopreventive or tumor promoting effects of SRD5A inhibition, we profiled gene expression changes in benign prostate epithelium from patients with PCa treated with dutasteride, a dual SRD5A inhibitor. Subjects were aged 45-80 years with clinically localized PCa (T1C to T2b), Gleason score <7, and serum PSA 2.5-10 ng/dL. 81 men were randomized to immediate RP (n=25) or to dutasterdie at 0.5 mg (n=26) or 3.5 mg (n=24) orally per day for four months prior to RP. Prostate samples embedded in OCT were used for laser capture microdissection (LCM). Keywords: clinical trial, Dutasteride, PEDB, dose response, prostate cancer, microarray
