Preoperative Breast MRI: Current Evidence and Patient Selection

Area of Science:

• Oncology
• Radiology
• Medical Imaging

Background:

• Breast MRI is highly sensitive for assessing newly diagnosed breast cancer extent.
• Its role in preoperative evaluation remains debated due to specificity concerns and variable clinical outcome translation.
• Current treatment paradigms may not fully leverage the detailed disease depiction offered by MRI.

Approach:

• This review synthesizes evidence on the use of preoperative breast MRI for breast malignancies.
• It examines data related to patient factors influencing MRI eligibility (age, tumor phenotype, breast density).
• The review analyzes the impact of preoperative MRI on surgical outcomes and long-term recurrence and survival.

Key Points:

• Breast MRI can detect occult cancers but may lead to false positives and overestimation of disease.
• Improved anatomic depiction by MRI has not consistently improved clinical outcomes like re-excision or recurrence rates.
• Inconsistent utilization of preoperative MRI highlights the need for clearer guidelines and evidence.

Conclusions:

• The review discusses the history, current use, and recommendations for preoperative breast MRI.
• It evaluates the evidence supporting breast MRI in specific patient populations.
• The impact of preoperative MRI on surgical results and long-term outcomes is critically assessed.
