[Prevention of postoperative recurrence of bladder cancer: a clinical study]
1Department of Urolagy, Jinan General Hospital of People's Liberation Army, Jinan 250031.
Objective:
To lower postoperative recurrence rate of bladder cancer, the prophylactic effects of five kinds of method on bladder cancer were evaluated.
Methods:
Between 1982 and 1997, 313 patients after TURBT or partial cystectomy were followed up for 2 to 15 years (average 7.6 years). These patients were divided into six groups: BCG, mitomycin C (MMC), thiotepa, Chinese herb medicine Zhuling (Grifola umbellata pilat), afterloading brachytherapy and control group. The prophylactic effects of them on postoperative recurrence of bladder cancer was evaluated.
Results:
During the follow-up, the recurrence rates were 35.1% in BCG group, 34.9% in Zhuling group, 41.7% in MMC group, 52.6% in thiotepa group, 64.7% in control group, respectively. 25 high-risk patients with invading or multiple bladder cancer were treated by afterloading brachytherapy. They were followed up from 12 to 42 months, with a recurrence rate being 24.0%.
Conclusions:
The prophylactic effect of Zhuling and BCG on bladder cancer recurrence was better than MMC. The vale of thiotepa was not significant. The afterloading brachytherapy was of great vale to invading or recurrent, multiple bladder cancer.
