Detailed Description

Multidisciplinary management improves complex treatment decision making in cancer care, but its impact for bladder cancer has not been documented. Although radical cystectomy (RC) has long been the standard of care for the management of muscle-invasive bladder cancer (MIBC), a multidisciplinary approach has led to the development of bladder-preservation therapy using maximal transurethral resection (TURBt) followed by radiotherapy with concomitant radio-sensitizing chemotherapy for MIBC. There are no randomized-controlled data comparing radical cystectomy with multidisciplinary bladder-preservation therapy (MBPT) available for comparison. However, observational data continues to support the use of MBPT as an acceptable alternative for patients with MIBC who wish to preserve their bladder or are not candidates for cystectomy because it may result in equivalent disease outcomes in select patients and offers the benefit of maintaining a functioning urinary system with subsequent improvements in quality of life. But there are also lots of issues need to be studied, such as the patient selection, approaches for completeness of TURBt, choices of radio-sensitizing chemotherapy, accuracy of radiotherapy and so on. In this study, the investigators plan to prospectively recruit 80 MIBC patients, who don't want to receive RC or are not candidates for RC, treated with MBPT from Nov 2018 to Dec 2020 in Peking University Third Hospital. The investigators will collect, compare and analyze their clinic-pathological data before and after MBPT, in order to confirm the safety and efficacy of MBPT for MIBC in China. At the same time, the investigators want to find out the patients who are not suitable for MBPT and the approach which can improve the efficacy of MBPT, as a result, the investigators intend to make a standard MBPT approach for Chinese MIBC patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

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
Complete response rate
Time Frame: 6-8 weeks after chemoradiation
Response to MBPT depending on cystoscopy, TURBt, or urinary cytology
6-8 weeks after chemoradiation
Disease specific survival (DSS) time
Time Frame: From date of treatment initiation until the date of death due to bladder cancer, assessed up to 60 months.
Events were defined as death attributable to bladder cancer. The time to DSS was the interval between treatment initiation and death due to bladder cancer, or the most recent follow-up if no event occurred.
From date of treatment initiation until the date of death due to bladder cancer, assessed up to 60 months.
Overall survival (OS) time
Time Frame: From date of treatment initiation until the date of death due to any cause, assessed up to 60 months.
Events were defined as death due to any cause. The time to OS was the interval between treatment initiation and death, or the most recent follow-up if no event occurred.
From date of treatment initiation until the date of death due to any cause, assessed up to 60 months.

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
