tumor debulking
Surgical reduction of tumor volume when complete resection is not feasible, aimed at relieving symptoms and improving treatment efficacy.
Full Definition
Tumor debulking is a surgical strategy focused on removing as much tumor tissue as possible when complete resection is not achievable due to location, vascularity, or risk to critical structures. The primary goals include relieving mass effect, reducing intracranial pressure, obtaining tissue for diagnosis, and potentially improving the effectiveness of subsequent therapies by reducing tumor burden. While debulking does not cure the disease, it can provide symptomatic relief and may enhance the penetration and efficacy of radiation therapy and chemotherapy by reducing the number of resistant tumor cells.
Usage
Usage note: Implies partial removal with symptom relief as primary goal rather than cure.
