Surgical intervention in patients with metastatic renal cancer: current status of metastasectomy and cytoreductive nephrectomy.
It is estimated that in 2004 there will be 35,700 new cases of, and 12,480 deaths from, kidney cancer in the US. Since 1950 there has been a 126% increase in the incidence of renal cancer and a 36.5% increase in annual associated mortality. In the past two decades, our understanding of tumors arising from the renal cortex has dramatically expanded owing to advances in cytogenetics and histopathological reclassification. It is now known that renal cell carcinoma (RCC) is a family of neoplasms that possess unique molecular and cytogenetic defects, with 90% of metastases emanating from conventional clear cell carcinoma subtype. In addition to advancing our understanding of RCC, improved abdominal imaging technology has caused a migration of tumor stage and alteration of surgical strategies, with tumors commonly being diagnosed at an earlier stage. Despite these advances, the prognosis for patients with metastatic RCC is poor. Studies that examine combinations of surgery and systemic therapy aim to improve survival in this high-risk group.
