tumor bed
The anatomical location from which a tumor has been surgically removed, often marked for radiation therapy planning.
Full Definition
The tumor bed refers to the anatomical space or tissue area from which a primary tumor has been surgically excised. This concept is particularly important in breast-conserving surgery and radiation oncology, where accurate identification of the tumor bed is crucial for treatment planning. Surgical clips or other markers are often placed in the tumor bed during surgery to help radiation oncologists precisely target the area for adjuvant radiation therapy. The tumor bed represents the highest-risk area for local recurrence and therefore receives boost radiation doses. Proper identification and marking of the tumor bed is essential for optimal oncologic outcomes and coordination between surgical and radiation teams.
Usage
Usage note: Important for multidisciplinary communication between surgical and radiation oncology teams.
