subtotal resection
Incomplete surgical removal of a tumor or lesion, typically due to proximity to critical structures.
Full Definition
Subtotal resection refers to the intentional incomplete surgical removal of a brain tumor or lesion, typically performed when complete resection would pose unacceptable risk to neurological function. This surgical strategy is often employed for tumors involving eloquent brain areas, those with significant vascular involvement, or deeply seated lesions near critical structures. The extent of resection is usually quantified as a percentage of tumor removal (e.g., 90% subtotal resection). Subtotal resection may be followed by adjuvant radiation therapy or chemotherapy to address residual tumor tissue.
Usage
Usage note: Specify percentage of resection when possible; distinguish from debulking which implies symptom relief.
