Background There is currently no formal prostate cancer screening programme in the UK. Early detection using age-based prostate-specific antigen (PSA) testing is unlikely to be cost-effective due to limited mortality benefit and harms associated with overdetection. However, the discovery of new prostate cancer specific biomarkers and more accurate diagnostic strategies (e.g. magnetic resonance imaging (MRI)) could improve the outcomes of screening. A systematic review was conducted to assess the evidence base on cost-effectiveness of such innovations and areas for further development. Methods To identify model-based economic evaluations of screening and diagnostic tests for prostate cancer, a systematic review of the literature using the NHS Economic Evaluation Database, Medline, EMBASE, HTA databases, NICE guidelines, and UK National Screening Committee guidance was carried out, between 2009 and 2019. Relevant data were extracted on study type, model inputs, modelling methods and cost-effectiveness conclusions and the results narratively synthesized. Results Sixteen studies were included in the review. Seven studies compared the cost-effectiveness of new urinary or blood biomarkers compared to each other or the PSA test and found the biomarkers e.g. the Prostate Health Index (PHI) and SelectMDx, to be the most cost-effective. Seven studies compared newer prostate biopsy methods, including MRI-guided, to TRUS guided biopsy and found MRI-guided methods to be most cost-effective. The newer detection methods showed a reduction in unnecessary biopsies and overtreatment. However, there was uncertainty around the most cost-effective pathway of follow-up strategies (MRI/biomarkers) in men who have a negative initial biopsy. Many studies did not model stage or grade of cancer, cancer progression or the entire testing, screening and treatment pathway. Very few studies fully accounted for uncertainty in their analysis. Conclusions This review brings together the cost-effectiveness literature for novel screening and testing methods used in the diagnosis of prostate cancer. Several limitations of the published models were identified. The models generally either compared new biomarkers or new imaging techniques which highlights the importance of future work in this area, as biomarkers and imaging are likely to be used in combination.
