Methods 28 patients with superficial bladder cancers were randomized into combined interventional chemotherapy and intravesical instillation of mitomycin or intravesical instillation of mitomycin alone for preventing recurrence after local ablation. The result was assessed by x2 test. Results The patients have been followed up for 12-26 months (mean 21 months). 1 case has had tumor recurrence in the combined modality therapy group and 4 in the intravesical instillation alone group, the tumor recurrence rate being 7% (1/14) and 29% (4/14) respectively (P【0.05). Conclusion Combined use of interventional chemotherapy and intravesical instillation of mitomycin is effective in preventing superficial bladder cancer from recurring after local ablation with fewer adverse effects. The ragimen is not only reliable but展开更多

There are numerous reports of trials of intravesical instillation of anticancer agents with the objective of lowering this recurrence rate. The aim of this study was to compare the prophylactic efficacy and safety of epirubicin （EPI）, pirarubicin （THP） and hydroxycamptothecin （HCPT） in superficial bladder cancer.Methods This study enrolled a total of 189 patients who had been diagnosed with superficial bladder cancer during the period from 2004 through 2007 at Beijing Friendship Hospital. All patients were randomly allocated to one of three treatment groups. Patients in group A received 29 doses of EPI 30 mg/30 ml, patients in group B received 29 doses of THP 30 mg/30 ml, and patients in group C received 29 doses of HCPT 30 mg/30 ml, over a period of 24 months.Results The recurrence-free rate in the 2 anthracycline treatment groups （A and B） were significantly better than that of the HCPT treatment group. In the safety evaluation, the incidences of pollakiuria, pain on urination, dysuria, hematuria,and contracted bladder were not significantly different between groups A and B, but some were significantly higher in groups A and B than that in group C.Conclusion The efficacy of EPI and THP was significantly better than HCPT in the prevention of bladder cancer recurrence.展开更多

The serum level of tumor necrosis factor (TNF) was significantly increased in 17 patients after IL-2 therapy. Recurrence occurred in 4 patients during the follow-up period of 10-18 months. The basic level of serum TNF was low and was not increased or even decreased after IL-2 in these patients. On the contrary, recurrence did not occur in another 5 patients with low basic level of TNF, but it was significantly increased after treatment of IL-2. TNF played a key role in preventing the recurrence of bladder cancer. The patients who had low basic level of TNF, which did not markedly increase or even decrease after IL-2 therapy were at high risk of recurrenc展开更多
