ACR Appropriateness Criteria® Imaging of Invasive Breast Cancer.

Area of Science:

• Oncology
• Radiology
• Evidence-Based Medicine

Background:

• Increasing invasive breast cancer diagnoses necessitate clear imaging guidelines for staging and surveillance.
• Unnecessary imaging can lead to delayed care and adverse outcomes, highlighting the need for evidence-based protocols.
• Understanding appropriate imaging indications is crucial for effective breast cancer management.

Purpose of the Study:

• To define the evidence-based role of imaging in breast cancer staging and surveillance.
• To outline indications for extent of disease evaluation and staging to prevent unnecessary procedures.
• To guide the appropriate use of imaging in asymptomatic patients post-treatment and for recurrence detection.

Main Methods:

• Systematic analysis of peer-reviewed medical literature.
• Application of established methodology principles like Grading of Recommendations Assessment, Development, and Evaluation (GRADE).
• Utilization of the RAND/UCLA Appropriateness Method for evaluating imaging procedures in specific clinical scenarios.

Main Results:

• No role for imaging in screening for distant recurrence in asymptomatic patients treated with curative intent.
• Annual 2-D mammography and/or tomosynthesis recommended for surveillance to detect in-breast recurrence or new primary breast cancer.
• Magnetic Resonance Imaging (MRI) is increasingly used as an additional screening tool, particularly for women with dense breasts.

Conclusions:

• Evidence-based guidelines, such as the American College of Radiology Appropriateness Criteria, are vital for optimizing breast cancer imaging.
• Expert consensus plays a role in formulating recommendations when literature is lacking or equivocal.
• Appropriate imaging strategies ensure timely detection while minimizing risks associated with unnecessary procedures.
