Methods: We measured the T lymphocytes, B lymphocyte and NK cells, and determined the population of Thl, Th2, Tcl and Tc2 of peripheral blood samples taken from 26 HCC patients before and after RFA. Results: The proportion of Typel cells (Thl and Tcl) and NK cells were significantly increased after RFA, especially in patients of the following subgroups: male, age〉55 years, pathological grade Ⅰ-Ⅱ tumor, clinical stage Ⅰ-Ⅱ or Child-Pugh A and B. Conclusion: TypeⅠ cells and NK cells in HCC patients were increased in a short period after RFA.展开更多
