The purpose of this paper is to examine the levels of cytokines in the lymph involved in the pathogenesis of breast cancer. Methods: Breast cancer was induced by introducing n-methyl-N-nitrosourea rats Wistar breed. Some of the animals subjected to surgery alone or chemotherapy alone (cyclophosphamide, methotrexate, 5-fluorouracil). Some animals combine both types of therapy, as well as a separate group to the administration of chemotherapy added Panagene drag presenting a fragmented DNA. To investigate the concentration of cytokines used in lymph test system Bio-Plex Pro Rat Cytokoness 24-Plex Assay (Bio-Rad, USA). Results: In rats with breast cancer content of most studied cytokines such as, IL-1b, IL-2, IL-4, IL-6, IL-7, IL-12, IL-13, IL-17A, MIP-1a, MIP-3a, RANTES, TNF-a, MCP-1 was significantly higher than in intact animals. Surgical removal of the tumor resulted in a significant decrease in the content in the lymph as a pro-inflammatory cytokine. Comparative performance study cytokine content in the lymph after tumor removal from intact animals showed that the content of cytokines such as IL-10, IL-18, GRO / KC, RANTES were significantly higher in the control animals group. Conducting chemotherapy has led to a significant decrease in the content of IL-1b, IL-4, IL-6, IL-7, IL-10, MIP-1a, MIP-3a, RANTES in rat breast cancer lymph. Comparative study of cytokine content in the lymph operated animals after the administration of chemotherapy and Panagene revealed that most of the content indicators cytokines such as IL-5, IL-6, IL-7, IL-10, IL-13, IL-17A, IL- 18, GRO / KC, IFNg, MIP-3a in the lymph was higher after administration of the drug Panagene. Conclusion: In a comparative study cytokine profile lymph Wistar rats found that cytokine content depended on the therapy in animals with induced breast cancer. Lymph cytokine levels may serve as a diagnostic criterion for tumor growth, as well as the predictor of the effectiveness of the therapy and the risk of metastasis of breast cancer.
