TABLE 2: Staging of Wilms' tumor STAGE DESCRIPTION % OF CASES Stage I Limited to the kidney and completely 40% resectable with renal capsule intact Stage II Tumor infiltrates beyond kidney, 20-25% completely resected; includes tumor with local spillage confined to flank Stage III Residual tumor confined to abdomen, 20-25% includes (a) positive abdominal nodes, (b) diffuse peritoneal contamination by direct growth, implants, or spillage, (c) positive margins, or (d) residual non resected tumor Stage IV Hematogenous disease (added: lungs, 10% lymph nodes, liver) Stage V Bilateral disease; each side should be 5%

The well-encapsulated and sharply demarcated tumor extended from the hilum to the renal capsule, but did not breech the capsule.
