cytoreduction surgery
Surgical approach aimed at reducing tumor burden in patients with metastatic neuroendocrine tumors.
Full Definition
Cytoreduction surgery, also known as debulking surgery, involves surgical removal of as much visible tumor as possible in patients with metastatic neuroendocrine tumors, even when complete resection cannot be achieved. The goal is to reduce overall tumor burden to improve symptom control, enhance the effectiveness of systemic therapies, and potentially extend survival. In NET patients, cytoreduction is particularly beneficial for those with functional tumors causing debilitating symptoms, as reducing tumor mass can decrease hormone production. The procedure typically involves resection of the primary tumor and removal of accessible metastatic deposits, most commonly in the liver, and is often combined with other local therapies.
Usage
Usage note: Particularly beneficial in functional NETs for symptom control even without cure.
