Official title
A Multicenter Prospective Randomized Controlled Clinical Trial of Hyperthermic Intravesical Chemotherapy After Transurethral Resection of Bladder Tumors in Patients With Non-Muscle-Invasive Bladder Cancer
Overview
The purpose of this study is to determine the efficacy and safety of Hyperthermic Intravesical Chemotherapy (HIVEC) with Gemcitabine (GEM) after Transurethral Resection of Bladder Tumors (TURBT) in the treatment of medium or high-risk group Non-Muscle-Invasive Bladder Cancer (NMIBC).
Detailed description
In this study, patients with Non-Muscle-Invasive Bladder Cancer (NMIBC) and planed to undergo Transurethral Resection of Bladder Tumors (TURBT) are randomized into HIVEC group and control group. In HIVEC group, HIVEC is performed with Gemcitabine Gemcitabine (3g/150ml NS) at 45 °C for 60 minutes within 4 weeks, once a week (±5 days) for 6 to 8 times, once a month to 1 year. For the patients in the control group, Intravesical Chemotherapy is administered after TURBT. The primary endpoint is 2-year recurrence rate. Secondary end points include 1-year recurrence rate, recurrence-free survival (RFS) rate, disease free survival (DFS) rate, time to treatment failure (TTF), Success rate of therapeutic operation, Instrument performance evaluation, quality of international prostate symptom score, quality of Urinary Symptoms Distress Score. All efficacy analyses are conducted in the intention-to-treat population. Safety analysis include only patients who receive their randomly assigned treatment.
Interventions
- Procedure TURBT
Transurethral Resection of Bladder Tumors - Procedure HIVEC
Hyperthermic Intravesical Chemotherapy with Gemcitabine (3g/150ml NS) at 45 °C for 60 minutes. Induction perfusion was required to start within 4 weeks, once a week (±5 days) for 6 to 8 times. After the last induction infusion, maintenance infusion was performed, once every month (±2 weeks) for 1 year from the first induction infusion. - Procedure Intravesical Chemotherapy
Intravesical Chemotherapy with Gemcitabine (3g/150ml NS). Induction perfusion was required to start within 4 weeks, once a week (±5 days) for 6 to 8 times. After the last induction infusion, maintenance infusion was performed, once every month (±2 weeks) for 1 year from the first induction infusion. - Drug Gemcitabine
Gemcitabine (3g/150ml NS).
Primary outcome measures
- Recurrence rate [Time frame: 2-year]
Secondary outcome measures (6)
- 1-year recurrence rate [Time frame: 1-year]
- Recurrence-free survival (RFS) rate [Time frame: 2-year]
- Time to treatment failure [Time frame: 2-year]
- Success rate of therapeutic operation [Time frame: 2-year]
- Quality of international prostate symptom score [Time frame: Evaluation was performed during the screening period and at 3, 12 and 24 months after initiation of treatment.]
- Quality of bother of score [Time frame: Evaluation was performed during the screening period and at 3, 12 and 24 months after initiation of treatment]
Eligibility criteria
Inclusion criteria
- Patients who did not receive induction perfusion within 4 weeks after complete resection of bladder tumor with TURBT (Patients who were judged by the investigator to be in need of secondary electrotomy, for the last time).
- Recurrence risk and prognosis of Non-Muscle-Invasive Bladder Cancer were divided into medium-risk group or high-risk group (patients who underwent multiple electrosurgical biopsies, and the pathological results were based on higher grade tumors).

Exclusion criteria
- Patients with bladder cancer in situ.
- Combined with proven upper urinary tract or urethral tumors.
- The patients were complicated with bladder perforation, gross hematuria or urinary tract infection of grade 3-4.
- Patients with urethral discontinuity, urethral stricture, or inability to use a three lumen catheter normally affect perfusion therapy.
- Patients who had undergone partial cystectomy or abnormal bladder structure were judged by the investigator to be unsuitable for perfusion therapy.
