debulking
Surgical reduction of tumor mass when complete removal is not technically feasible.
Full Definition
Debulking refers to the surgical strategy of removing as much tumor tissue as possible when complete resection cannot be safely achieved due to tumor location, size, or involvement of critical structures. This approach is commonly employed in ovarian cancer, brain tumors, and other malignancies where the goal shifts from cure to palliation or enhancement of subsequent treatments. Optimal debulking typically refers to leaving residual disease smaller than a specified diameter, usually 1 cm, which has been associated with improved response to chemotherapy and better survival outcomes.
Usage
Usage note: Often qualified as 'optimal' or 'suboptimal' debulking based on residual disease volume.
