ACR Appropriateness Criteria^® Prostate Cancer-Pretreatment Detection, Surveillance, and Staging

Area of Science:

• Oncology
• Radiology
• Medical Imaging

Background:

• Prostate cancer is a significant cause of cancer-related mortality in American men, second only to lung cancer.
• Accurate disease characterization, including presence, extent, and aggressiveness, is vital for baseline evaluation.
• Diagnosis often follows elevated prostate-specific antigen (PSA) or abnormal digital rectal examination (DRE).

Purpose of the Study:

• To outline the essential elements of baseline prostate cancer evaluation.
• To highlight the role of advanced imaging techniques in disease characterization.
• To discuss the application of evidence-based guidelines in clinical decision-making for prostate cancer management.

Main Methods:

• Review of diagnostic modalities including serum PSA, DRE, transrectal ultrasound-guided biopsy, and MRI-targeted biopsy.
• Emphasis on multiparametric MRI (mpMRI) for local prostate cancer evaluation.
• Description of bone scintigraphy and CT for detecting distant metastases in intermediate- to high-risk disease.

Main Results:

• Multiparametric MRI is a powerful tool for local prostate cancer assessment.
• Bone scintigraphy and CT are key for identifying bone and nodal metastases.
• The American College of Radiology Appropriateness Criteria provide evidence-based guidance for imaging procedures.

Conclusions:

• Comprehensive disease characterization is fundamental for effective prostate cancer management.
• Advanced imaging, particularly mpMRI, plays a critical role in accurate staging.
• Evidence-based guidelines, like the ACR Appropriateness Criteria, inform optimal imaging and treatment strategies.
