| Sumario: | The major medical problem in the treatment of skin melanoma is improvement methods of treatment, increasing their effectiveness and safety. In this study, adoptive immunotherapy, using lymphocytes activated in vitro, was performed in 15 patients with metastatic melanoma. Evaluated the phenotype of peripheral blood lymphocytes and activation markers (HLA-DR, CD25, CD314, CD38, CD69) before and 3-4 weeks after immunotherapy. It is shown that for these patients is characterized by increasing the number of CD25+ and Treg lymphocytes in the bloodstream, which has not changed after immunotherapy. Adoptive immunotherapy in combination with chemotherapy resulted in a decrease of absolute number of lymphocyte, B- and T-lymphocytes, T helper cells, NKT-cells, CD314+ lymphocytes, CD38+ lymphocytes and immature T-lymphocytes (CD3+CD38+) (р < 0,05). However, there was a positive dynamic to increase the percentage of NK-cells to 32% and CD69+NK-cells to 21% and significant increase in expression of HLA-DR on all lymphocytes (p < 0.05). Adoptive immunotherapy characterized by the absence of side effects and can be recommended as accompanying to basic radiation and chemotherapy. |
