Lessons learned in the surgical management of renal cell carcinoma.

Surgical excision, the mainstay of management of renal cell carcinoma (RCC), has evolved significantly over the last 4 decades. Radiological imaging is crucial to the diagnosis and staging of RCC, and technological advances have facilitated more precise preoperative assessment. Additionally, wider use of cross-sectional imaging modalities has led to increasing incidental diagnosis of small, early-stage RCC. Nephron-sparing surgery (NSS), originally developed to treat RCC arising in a solitary functioning kidney, has been demonstrated to be a safe and effective alternative to radical nephrectomy. NSS is now also applicable to tumors of suitable size and anatomy in patients with a normal contralateral kidney, thus facilitating preservation of renal function and management of metachronous contralateral pathology. Laparoscopic and percutaneous approaches have developed over the last decade, thus providing minimally invasive modalities, with shortened convalescence and improved cosmesis. Advanced RCC, involving venous extension or nodal spread, is increasingly amenable to surgical management, although appropriate patient selection is crucial. Furthermore, surgical excision of the primary lesion appears to be an integral part of systemic therapy for metastatic RCC.
