Topic: Diagnosis/ Referral
Introduction: Our study assesses the value of preoperative MRI in characterizing the extent of breast cancer, identifies risk factors associated with additional MRI lesions not visualized on prior imaging, and evaluates the impact on surgical management. Methods :A retrospective chart review was conducted on 199 patients with biopsy-proven breast cancer who underwent preoperative MRI between January 2014 and February 2018. We evaluated the accuracy of MRI at predicting the extent of disease, the frequency of additional lesions detected on MRI, and the changes in surgical management. Statistical analysis of associated risk factors was performed with the Chi-Square test and Fisher's exact test, with a P-value Results:MRI was 98% sensitive in detecting breast cancer and predicted tumor size within 10 mm of pathological tumor size in 155 (78%) patients. 72 (36%) MRIs detected additional lesions, which led to additional biopsy-proven sites of cancer in 37 (19%) patients. Surgical management was altered in 33 (17%) patients from either a lumpectomy to mastectomy, or mastectomy to bilateral mastectomy. Younger age (Conclusion:Preoperative MRI is a useful adjunct to conventional breast imaging in characterizing the extent of breast cancer and detecting additional lesions, particularly in younger patients, resulting in clinically relevant changes in surgical management.
