tumor debulking
Surgical reduction of tumor mass when complete resection is not feasible due to location or risk factors.
Full Definition
Tumor debulking refers to the surgical strategy of removing as much tumor tissue as possible while preserving neurological function, even when complete resection cannot be safely achieved. This approach is commonly employed for infiltrative tumors in eloquent brain areas, tumors with extensive vascular involvement, or cases where complete resection would result in unacceptable morbidity. Debulking can provide symptomatic relief by reducing mass effect, improve the efficacy of adjuvant therapies such as radiation or chemotherapy, and potentially extend survival. The extent of debulking is often quantified as a percentage of tumor volume removed, with maximal safe resection being the goal while maintaining quality of life.
Usage
Usage note: Quantify the extent of debulking when possible (e.g., '90% debulking').
