简要总结
It is still a challenge for urologic surgeon to prevent the post transurethral resection of bladder tumor (TURBT) recurrence of moderate-high risk non-muscle invasive bladder tumor. Adjuvant chemotherapy is a standard treatment for local progressive bladder tumor, which contains mainstream GC treatment scheme. It is common to observe clinically moderate-high risk NMIBC recurrence after routine intravesical instillation.Systematic chemotherapy can eliminate remained tumor cells especially those from mucosa basal cells so as to improve the prognosis of patients. Our clinical trial aims to investigate whether the utilization of combination of GC treatment scheme and epirubicin instillation would decrease the recurrence of moderate-high risk NMIBC.
详细描述
Prevention of the post-transurethral resection of bladder tumor (TURBT) recurrence of moderate-high risk non-muscle invasive bladder cancer(NMIBC) is still a difficult problem. NMIBC was classified as low, moderate and high risk patients. Moderate-high risk NMIBC contained those are multiple, recurrent, II-III grade, tumor diameter >3cm, invasive to submucosa and associated with carcinoma in situ. For those patients, no matter which treatment was conducted, for example, exchanging instillation drugs, increasing medicine dose, appending adjuvant drugs and prolonging instillation time, would not improve the prognosis of these patients. Adjuvant chemotherapy is a standard treatment for local progressive bladder tumor, which contains mainstream GC treatment scheme. For muscle invasive bladder cancer patients, radical cystectomy with neoadjuvant chemotherapy will improve patients' tumor grade and increase overall survival and disease specific survival rate.Systematic chemotherapy can eliminate remained tumor cells especially those from mucosa basal cells so as to improve the prognosis of patients. Our clinical trial aims to investigate whether the utilization of combination of GC treatment scheme and epirubicin instillation would decrease the recurrence of moderate-high risk NMIBC. In addition, we also would like to investigate the improvement of life quality after TURBT of moderate-high risk NMIBC.

研究组 & 干预措施
Combination
Patients who were pathologically confirmed as moderate-high risk NMIBC. Epirubicin was immediately instilled in 24h after TURBT and regularly conducted for a year. Intervention: GC scheme systematic chemotherapy was underwent 5 days after TURBT, which contained gemcitabine 1000-1200mg/m2. Cisplatin (70mg/m2) was intravenous dripped in the first and 8th day after TURBT. Intravenous rehydration was conducted in the second day.
干预措施: Gemcitabine, cisplatin (Drug)
