tumor bed
The anatomical site remaining after tumor resection, often requiring adjuvant radiation therapy to achieve local control.
Full Definition
The tumor bed refers to the anatomical region from which a tumor has been surgically removed, including the immediate surrounding tissues that may harbor microscopic residual disease. In orthopedic oncology, accurate identification and delineation of the tumor bed is crucial for radiation therapy planning, particularly after marginal or intralesional resections. The tumor bed encompasses not only the primary tumor location but also areas of potential contamination including surgical approach routes, drain sites, and any areas exposed during the procedure. Proper tumor bed irradiation is essential for local control in many sarcoma cases.
Usage
Usage note: Essential to document tumor bed boundaries for radiation oncology planning.
