 AB    The lymphocytes and their subsets were determined in the peripheral
       blood of 62 gastric cancer patients and 68 controls using fluorescent
       conjugated monoclonal antibodies and flow cytometry (FACScan method). A
       significant increase in the total number of white blood cells from
       gastric cancer patients was noted in comparison to controls, but the
       percentage of lymphocytes was the same. The percentage of suppressor
       (cytotoxic) T cells (CD8) showed no difference in all stages of gastric
       cancer patients evaluated, but the percentage of helper (inducer) T
       cells (CD4) and the CD4/CD8 ratio decreased significantly in the
       advanced stages III and IV. Depression of the CD4/CD8 ratio was well
       correlated with tumor invasion, lymph node metastasis, and tumor size
       but not with sex, age, tumor location, gross type, or histologic
       differentiation. It appeared that the immune defect of gastric cancer
       patients was associated with the afferent arm (CD4) and worsened as the
       disease advanced. These results suggest that immunotherapy to stimulate
       the deficient immune system may play an important part in the
       multimodality treatment of patients with advanced gastric cancer.
