[EX Q]: Question: Does local lymph node involvement predict poor outcome in pediatric renal cell carcinoma?
Answer: Children with lymph node-positive RCC in the absence of distant metastatic disease had a relatively favorable long-term prognosis, with survival rate nearly triple those of adult historical controls.

Further investigation of the biologic differences between adult and pediatric RCC is warranted.
