Purpose: We evaluated temporal trends in systemic therapy use in patients undergoing cytoreductive nephrectomy for metastatic renal cell carcinoma. We used data from a large national cancer registry and assessed characteristics associated with the receipt of systemic treatment. Materials and Methods: We reviewed the NCDB to identify patients with stage IV renal cell carcinoma who underwent cytoreductive nephrectomy between 1998 and 2010. Systemic therapy was defined as immunotherapy and/or chemotherapy, including targeted agents. We evaluated associations between clinicopathological features and receipt of systemic therapy using multivariable logistic regression with generalized estimating equations. Results: Of 22,409 patients with metastatic renal cell carcinoma treated with cytoreductive nephrectomy 8,830 (39%) received systemic therapy. Use of systemic therapy increased from 32% of cases in 1998 to…(vermás)
