目的评价卡介苗多糖核酸 (BCG-PSN)膀胱灌注预防膀胱癌复发的疗效。方法随机选择 2 8例膀胱癌患者进行 BCG-PSN膀胱灌注 ,并于术前及灌注 3个月后分别测定外周血免疫状态。选择同期行丝裂霉素膀胱灌注的患者进行疗效比较。结果 BCG-PSN膀胱灌注能显著提高膀胱癌患者外周血免疫功能 ,降低术后复发率。结论 BCG-PSN是预防膀胱癌复发的较安全而有效的免疫促进剂。
Objective To evaluate the curative effect of intravesical instillation of BCG polysaccharide nucleic acid (BCG-PSN) on the recurrence of bladder cancer. Methods Twenty-eight bladder cancer patients were randomly divided into bladder perfusion of BCG-PSN and peripheral blood immune status were measured before surgery and 3 months after perfusion. Select the same line of mitomycin bladder irrigation in patients with efficacy comparison. Results BCG-PSN intravesical instillation can significantly improve the immune function of peripheral blood in patients with bladder cancer and reduce the recurrence rate. Conclusion BCG-PSN is a safe and effective immune promoter to prevent the recurrence of bladder cancer.
