intraoperative tumor localization
Real-time identification and mapping of tumor boundaries during surgery using various imaging or marking techniques.
Full Definition
Intraoperative tumor localization encompasses various techniques used during surgery to precisely identify tumor boundaries, satellite lesions, and critical anatomical structures in relation to the primary tumor. Methods include ultrasound guidance, fluorescence imaging, radiotracer localization, and tactile assessment. This process is crucial for achieving complete tumor removal while preserving healthy tissue and avoiding positive margins. The technique is particularly important in tumors that are non-palpable, deeply seated, or located near critical structures.
Usage
Usage note: Distinguish from preoperative localization procedures performed before surgery.
