Among available biomarkers, we considered Prolaris cell‐cycle progression (CCP) test, “triple hit” phenotype (ERG overexpression, PTEN and prostein expression loss) and elevated expression levels of TMPRSS2‐ERG gene fusions.MethodsWe performed a case‐control study, enrolling patients that entered the AS programme at our tertiary referral Institution. Men subsequently undergoing radical prostatectomy for progression were considered as “cases”, while men still on AS at the end of the follow‐up period were labeled as “controls”. CCP test, triple hit and TMPRSS2‐ERG expression analyses were performed on tumoral tissue retrieved from biopsies at enrollment. Their ability to distinguish “cases” and “controls” was evaluated. According to power analysis, the study required 40 patients.ResultsPatients had comparable baseline characteristics. CCP test suggested to continue AS in 75% of controls and to undergo an active treatment in 75% of cases. CCP molecular score (HR 8.5, p = 0.02) was significantly associated with progression in multivariable logistic regression. No significant differences were found in terms of “triple hit” or TMPRSS2:ERG expression. IHC analysis was feasible only in 17 patients due to insufficient material.ConclusionsCCP test may be a useful tool to estimate the risk of progression in PCa patients and guide the decision between AS and active treatment. Triple hit phenotype or TMPRSS:ERG fusion status was not associated with progression. 10.1002/pros.24921 http://creativecommons.org/licenses/by/4.0/
