Input: Consider Input: 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. Until highly effective therapies for RCC are identified, these children should not be exposed to adjuvant treatment. Further investigation of the biologic differences between adult and pediatric RCC is warranted.

Output: no
