Abstract:
AIM: To investigate the effect of microwave ablation of liver cancer on the cellular immunity in mice. METHODS: A C57BL/6J mouse model of liver cancer was established by subcutaneous injection of Hepa 1 - 6 cells. The tumors were subjected to microwave ablation under the ablation condition of 45 ℃, 50 ℃, 55 ℃ or 60 ℃ for 180 s. The CD4~+ T cells, CD8~+ T cells and natural killer cells (NK) in peripheral blood were detected by FACS. The cytotoxicity of splenic NK and splenic cytotoxic T lymphocytes (CTL) activated by inactivated Hepa 1-6 cells was assayed by LDH method. RESULTS: The proportions of CD4~+ T cells, CD8~+ T cells and NK cells in peripheral blood in 50 ℃ and 55 ℃ group at 21 d after ablation were significantly increased and that of NK cells in 60 ℃ group was significantly increased. There was no significant difference between those in group 42 d after ablation and control. The cytotoxicities of splenic CTL and NK cells in 50 ℃ and 55 ℃ groups at 21 d or 42 d after ablation were significantly increased, and they were much higher than those in 45 ℃ group at the same time. The cytotoxicities of splenic CTL in 50 ℃ and 55 ℃ groups at 21 d after ablation were much higher than that in 60 ℃ group at the same time. CONCLUSION: Under a certain ablation temperature, microwave ablation of liver cancer promotes the cellular immunity.
