    Abstract:
    AIM: In the present study, we conducted the quantitative analysis of peripheral blood lymphocytes population and subpopulation in patients with stomach cancer, based on flow cytometry immunophenotyping. MATERIAL AND METHOD: The results were compared with the advancement of the disease (UICC/TNM), histological type (Lauren classification), and grade of differentiation of stomach cancer. Lymphocyte CD: (CD3/CD19, CD3/CD4, CD3/CD8, CD3/CD16, 56) were determined in 50 cancer patients and 30 healthy humans. RESULTS: The significant deficiency of total lymphocyte number, T and B lymphocytes, as well as CD4+ and CD8+ was found in stomach cancer patients. There was no depletion in NK cells number. In advanced stomach cancer, the number of NK cells decreased, along with further deterioration of lymphocytes T and B populations. In patients with diffuse-type of stomach cancer and III or IV stage, the more pronounced deficiency in T, CD4+ and CD8+ population was noted. The decrease grade of differentiation was correlated with the increase of NK cell population. There was no correlation between the number of B lymphocytes and the histologic type or grade of differentiation of stomach cancer. CONCLUSION: The obtained data demonstrated significant quantitative defect in defence of stomach cancer patients.
