tumor bed irradiation
Focused radiation therapy delivered to the anatomical site of tumor resection to reduce local recurrence risk in high-risk cases.
Full Definition
Tumor bed irradiation is a targeted radiation therapy technique that delivers focused treatment to the anatomical area where a tumor was previously located and resected. This approach is particularly relevant in orthopedic oncology for soft tissue sarcomas with high-grade histology, close margins, or large size. The radiation field is carefully planned using post-operative imaging and surgical clips placed during resection to define the tumor bed. Treatment timing can be immediate (intraoperative), early post-operative, or delayed, each with distinct advantages and considerations for wound healing and functional outcomes.
Usage
Usage note: Timing of administration significantly affects wound healing and should be specified.
