title: [Mechanism of preventing the recurrence of bladder carcinoma by intravesical instillation of BCG plus IL-2].
abstract: OBJECTIVE
  To study the mechanism of preventing the recurrence of bladder carcinoma by intravesical instillation of BCG plus IL-2.
  
  
  METHODS
  Intravesical instillation of BCG or BCG plus IL-2 were carried out in the bladder transitional cell carcinoma patients undergoing surgical operation (16, 19 cases respectively).
  
  
  RESULTS
  They were followed up for 14-22 months. The recurrence rates were 31.25% and 21.05% respectively. At 6 weeks after the instillation of IL-2 plus BCG, the peripheral blood NKCF activity was increased significantly and there was a significant positive correlation between the activities of NKCF and IL-2.
  
  
  CONCLUSIONS
  The intravesical instillation of IL-2 plus BCG is clearly superior to only BCG in preventing recurrence of bladder carcinoma. There may be immuno-enhancement and immuno-synergism.
