cytoreduction
Pronunciation: sy-toe-ree-DUK-shun
Surgical reduction of tumor burden to improve treatment efficacy and patient outcomes.
Full Definition
Cytoreduction, also known as cytoreductive surgery or debulking, involves surgically removing as much tumor tissue as possible while preserving neurological function. In neurosurgical oncology, the extent of cytoreduction significantly impacts patient survival and quality of life. Maximum safe resection is the goal, as greater extent of resection correlates with improved outcomes in most brain tumor types. The procedure must balance aggressive tumor removal with preservation of eloquent brain functions, often requiring intraoperative monitoring and mapping techniques.
Usage
Usage note: Can be used as noun or adjective ('cytoreductive surgery'). Emphasizes tumor burden reduction rather than cure.
