Contemporary Management of Renal Tumors With Venous Tumor Thrombus

Purpose

Renal cell carcinoma with intravenous tumor thrombus remains one of the most intriguing and challenging topics in urological oncology. With better understanding of the biology of intravascular tumor invasion and improvements in overall survival, the surgical and medical treatment of these patients is being completely redefined.

Materials and Methods

We performed a MEDLINE® search for relevant articles on renal cell carcinoma with intravenous tumor thrombus.

Results

We describe the staging systems, prognostic factors and surgical techniques involved in the management of renal cell carcinoma with intravenous tumor thrombus. We also review long-term survival of local, advanced and metastatic renal cell carcinoma with tumor thrombus invasion. Finally, we propose a clinical algorithm for the treatment of patients with renal cell carcinoma invading the venous system.

Conclusions

Management of a kidney cancer tumor invading the venous system should now consider the primary biology and natural behavior of a given tumor in that specific patient rather than only focusing on the level and extent of venous invasion. Treatment must be individualized for every patient based on performance status, tumor biology and risk of surgery.
