卡介苗联合白细胞介素-2膀胱灌注预防膀胱癌复发机理的研究

目的探讨卡介苗（ＢＣＧ）联合白细胞介素－２（ＩＬ－２）膀胱灌注预防膀胱癌复发的机理。方法对３５例膀胱移行细胞癌术后患者分别行ＢＣＧ和ＢＣＧ加ＩＬ－２膀胱灌注,随访１４～２２个月,复发率分别为３１．２５％和２１．０５％。结果应用ＩＬ－２加ＢＣＧ膀胱灌注６周后,外周血天然杀伤细胞激活因子（ＮＫＣＦ）活性明显增强,在ＮＫＣＦ活性与ＩＬ－２活性间有显著正相关变化。结论ＩＬ－２加ＢＣＧ膀胱灌注预防膀胱癌复发作用明显优于单纯用ＢＣＧ,ＩＬ－２和ＢＣＧ两者间有免疫促进和协同作用。

Mechanism of preventing the recurrence of bladder carcinoma by intravesical instillation of BCG plus IL-2

OBJECTIVE: To study the mechanism of preventing the recurrence of bladder carcinoma by intravesical instillation of BCG plus IL-2. METHOD: 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). RESULT: 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. CONCLUSION: 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.
