Cytoreductive nephrectomy for metastatic non-clear cell renal cell carcinoma (RCC) may decrease cancer-specific mortality (CSM), a recent study suggests.
In a study of 851 patients with metastatic non-clear cell RCC, researchers found that patients who underwent cytoreductive nephrectomy had a significant 62% decreased risk of CSM than those who did not, according to results published online ahead of print in European Urology Focus.
The 2-year cumulative CSM rate was 52.6% for those who underwent cytoreductive nephrectomy group versus 77.7% for those who did not. The investigators observed a survival benefit of cytoreductive nephrectomy across histologic subtypes (papillary, chromophobe, collecting duct carcinoma).
Among contemporary patients (those diagnosed during 2010–2014), cytoreductive nephrectomy was associated with a 68% decreased risk of CSM.
Of the 851 patients, 67.6% underwent cytoreductive nephrectomy. The study population had a median age of 62 years and a median tumor size of 80 mm; 74.4% were men and 71.4% were white. Overall, 555 patients died during the study period.
