Modern integrative prostate cancer diagnostics

PURPOSE OF REVIEW: To review contemporary applications, performance, and implementation challenges of artificial intelligence (AI) in the radiological and pathological diagnosis of prostate cancer, and to highlight emerging multimodal AI biomarkers for prognosis and treatment selection. RECENT FINDINGS: In radiology, large multicenter studies demonstrate that MRI-based AI can detect clinically significant prostate cancer with accuracy comparable to, and in some contexts surpassing, expert radiologists, while reducing inter-reader variability and improving workflow efficiency. In surgical pathology, AI systems show high concordance with pathologists in cancer detection and Gleason grading, helping standardize challenging features such as Gleason pattern 4 and supporting triage or second-reader workflows. However, emerging transformative potential lies in multimodal AI systems that integrate digital histopathology with clinical and molecular data to deliver prognostic and predictive biomarkers. These tools are now being validated in randomized trials and real-world cohorts and are beginning to be recognized in clinical guidelines. SUMMARY: AI is a powerful assistive technology that can enhance diagnostic accuracy, reproducibility, and efficiency across MRI and pathology. The integration of multimodal data is catalyzing validated biomarkers to guide risk stratification and treatment decisions - the next frontier in personalized prostate cancer care. But broad adoption still requires rigorous external validation, quality assurance, and ongoing postdeployment monitoring.
