cytoreductive nephrectomy
Surgical removal of the primary kidney tumor in metastatic renal cell carcinoma to reduce tumor burden before systemic therapy.
Full Definition
Cytoreductive nephrectomy is a surgical procedure involving removal of the kidney containing the primary tumor in patients with metastatic renal cell carcinoma. The goal is to reduce the overall tumor burden in the body, potentially improving the effectiveness of subsequent systemic treatments such as targeted therapy or immunotherapy. This approach is based on evidence suggesting that removing the primary tumor may enhance immune function and reduce immunosuppressive factors produced by the cancer. Patient selection for cytoreductive nephrectomy requires careful consideration of performance status, extent of metastatic disease, and potential for benefit from systemic therapy.
Usage
Usage note: Distinguish from palliative procedures performed solely for symptom relief.
