Analysis of receptor-expression, CCP score, hormone levels and PSA: Tissue samples taken at surgery is placed in RNA-later before being frozen. The samples will be analysed using RNeasy plus Universal Mini Kits (QIAGEN), and Real-time polymerase chain reaction (PCR). ERα, ERβ and AR mRNA expression will be determined using TaqMan assay. For analysis of CCP score, the pathologist select regions of carcinoma and RNA will be extracted as above; thereafter gene expression will be assessed according to the manufactures (Prolaris®) instruction. PSA-blood levels will be analysed according to standard clinical protocol.
