The impact of sex and age on distribution of metastases in patients with renal cell carcinoma.

Important age and sex-related differences exist in the distribution of RCC metastases. The distribution of metastases is marginally different between sexes. Specifically, more advanced age is associated with lower rates of thoracic and brain metastases in men and with lower rates of abdominal, bone and brain metastases in women. Age and sex should be take into consideration into the staging management strategy, as well as into the follow-up strategy of patients with metastatic RCC.
