title: [Study on the TIL and NK of IL-2 injected via pelvic retroperitoneal space in gynecological cancer patient].
abstract: OBJECTIVE
  To verify the feasibility and effect of biotherapy instituted via pelvic retroperitoneal space on gynecological cancer.
  
  
  METHODS
  Injecting IL-2 (and/or) 5-Fu through a tube installed in the pelvic retroperitoneal space. Counting the subpopulation of T cell and NK of lymph-nodes of pelvis after the drugs being by FCM.
  
  
  RESULTS
  The numbers of CD3+, CD4+, CD8+, CD25+ and NK cells in treatment group were significantly higher than those in the control group. And the numbers of these cells in the IL-2 + 5-Fu group were significantly higher than those in the 5-Fu group. The CD25+ and NK cell numbers in the IL-2 group were significantly higher than those in the 5-Fu group (P < 0.05).
  
  
  CONCLUSIONS
  The IL-2 injected via pelvic retroperitoneal space can promote the activity, development and infiltrating of T cell and NK cell in the tumor tissue.
