March 18, 2024 updated by: Affiliated Cancer Hospital & Institute of Guangzhou Medical University

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

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).

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Recurrence rate
Time Frame: 2-year
The patients were observed for 2 years since they received HIVEC or intravesical chemotherapy，and cystoscopy was repeated every 3 months. If a new tumor-like organism is seen under the microscope, and pathology indicates urothelial carcinoma of the bladder after TURBT or cystoscopic biopsy, the tumor is considered to have recurred. 2-year recurrence rate = number of recurrence cases within 2 years / total number of enrolled cases * 100%.
2-year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
1-year recurrence rate
Time Frame: 1-year
1-year recurrence rate = number of recurrence cases within 1 years / total number of enrolled cases * 100%.

Recurrence-free survival (RFS) rate
Time Frame: 2-year
Recurrence free survival is calculated from the date of randomization to the date of record recurrence or death from any cause, whichever occurred first.
2-year
Time to treatment failure
Time Frame: 2-year
Time to treatment failure is calculated from the date of randomization to the date of treatment discontinuation/termination, including any reason for discontinuation/termination, such as disease progression, death, withdrawal due to adverse events, subject's refusal to continue the study, or use of a new treatment.
2-year
