title: Clinical studies on cell-mediated immunity in patients with renal cell carcinoma: interleukin-2 and interferon-gamma production of lymphocytes.
abstract: The authors examined interleukin-2 (IL-2) production and interferon gamma (IFN gamma) production of peripheral blood mononuclear cells in 28 patients with renal cell carcinoma and 17 control subjects. The peripheral blood was obtained prior to the initiation of therapeutic procedures. The patients were divided into two groups according to tumor size, less than or equal to 5 cm and greater than 5 cm. The production of IL-2 and IFN gamma was measured by immunoradiometric assay. As a result, in the patients with tumors greater than 5 cm, IL-2 and IFN gamma production was impaired. However, in the patients with tumors less than or equal to 5 cm, IFN gamma production was enhanced, though IL-2 production was not significantly different from that of the control subjects. There was no significant correlation between IL-2 production and IFN gamma production.
