 AB    A wide range of immunological abnormalities have been described in
       renal-cell carcinoma (RCC). The only constant one was the decrease of
       CD4/CD8 ratio, reversible following radical nephrectomy in the absence
       of metastases. Alpha-interferon was administered with variable benefit
       to patients with metastatic RCC. The aim of this study was to document
       whether the treatment of patients with metastatic RCC, with unpurified
       human alpha-interferon, induced any change in the number and functional
       properties of peripheral blood T lymphocytes and monocytes. Fifteen
       patients were included in the study; all were treated with IFN 2,000,000
       IJ/24h x 15 days, with an intercycle interval of 15 days during at least
       4 cycles. The immunological analyses included the percentage and
       absolute number of E-rosette forming cells, CD3+, CD4+, CD8+ and CD4/CD8
       ratio as well as the percentage and absolute number of monocytes and
       their phagocytic index toward the yeast particles. The analyses were
       done before the treatment and after the 4th cycle of the IFN therapy and
       compared toward the same analyses done in 22 healthy controls. Following
       IFN treatment two significant changes were noted: a decrease in CD4/CD8
       ratio (mean 1.050 fall for 19% to 44%, mean 27.25% from the initial
       value) as well as a marked decrease in monocyte phagocytic index (p <
       0.005). These data point to either disease-related or treatment-related
       decrease in the phagocytic properties of monocytes and the decrease of
       CD4/CD8 ratio.
