The Radiologist's Role in a Breast Multidisciplinary Tumor Board

Breast multidisciplinary tumor boards (MTBs) play an important role in determining treatment. This article serves as a guide for the radiologist participating in a breast MTB, as the information presented at MTB can significantly influence treatment plans and dictate future steps for further patient work-up. Multidisciplinary tumor board preparation involves a careful review of the patient's history while gathering all relevant imaging studies, and reinterpreting them when appropriate. Presented images should be carefully selected, annotated, and displayed clearly before providing final recommendations for localization and incompletely assessed findings. Anatomic staging factors from the AJCC Breast Cancer Staging System, such as tumor size and degree of suspected skin involvement, should be described. In addition, there are many other types of information that the treatment specialists want to know. The surgeon is interested in anatomic information that will help them decide whether breast conservation therapy is feasible or if local structures, such as the nipple, can be spared. The radiation oncologist may need to know whether accelerated partial breast irradiation is feasible or if postmastectomy radiation therapy is indicated. The medical oncologist is looking for factors that may provide an indication for neoadjuvant therapy and ensuring there is a reliable follow-up method for evaluating the response to treatment, such as comparative MRI. Additionally, all specialists need to know the extent of suspected nodal involvement. By clearly and comprehensively presenting this information to the rest of the MTB team, the radiologist provides a vital contribution that guides treatment and ensures adherence to clinical guidelines.
