[Phenotypic difference of lymphocytes circulating in tumorous renal artery and renal vein in patients with renal cell carcinoma].
Phenotypic difference of lymphocytes circulating in tumorous renal artery and renal vein in patients with renal cell carcinoma was studied. Fifteen patients with no prior treatment were studied, from whom blood samples were taken at the time of radical nephrectomy. Mononuclear cells separated from tumorous renal arterial and venous blood were analyzed for cell surface markers. CD3, CD4, CD8, CD11b, CD16, CD25, CD57, Leu8 HLA-DR were compared. CD25 positive cells were significantly increased in venous blood than in arterial blood in the kidneys with tumor. No significant difference was found regarding the other surface markers.
