We evaluated the cost‐effectiveness of a combined PSMA PET/CT and mpMRI biopsy‐free diagnostic approach for clinically significant prostate cancer (csPCa). Method A decision tree model was designed to compare two diagnostic strategies for csPCa in men with raised Prostate Specific Antigen (PSA)—the first with conventional mpMRI followed by transperineal prostate biopsy versus a second biopsy‐free, PSMA PET/CT plus mpMRI combined imaging strategy. We evaluated the impact of each strategy on costs and Quality‐Adjusted‐Life‐Years (QALYs). Willingness‐to‐pay thresholds were set at 1× and 3× Gross Domestic Product (GDP). One‐way sensitivity analysis and probabilistic sensitivity analyses were performed. Results A combined mpMRI and PSMA PET/CT diagnostic strategy was 0.04 QALY more effective but SGD$4088.03 more expensive than the conventional mpMRI and biopsy strategy. The incremental cost‐effective ratio (ICER) was SGD$92782.87 per quality‐adjusted life year (QALY). In the combined imaging strategy, 3.5% of the cohort had a missed diagnosis of prostate cancer versus 13.9% in the conventional mpMRI and biopsy strategy. Probabilistic analyses showed that the combined imaging strategy was cost‐effective at willingness‐to‐pay thresholds of SGD$121160 and SGD$363480, respectively. Conclusion Combined mpMRI and PSMA PET/CT for csPCa diagnosis are a cost‐effective strategy in terms of health utility over the conventional approach for diagnosing csPCa in men with raised PSA, potentially reducing the need for invasive diagnostic procedures. 10.1002/bco2.70172 http://creativecommons.org/licenses/by/4.0/ |
