About this study

Official title: Clinical and Economic Outcomes of Radical Cystectomy Among NMIBC and MIBC Patients: Nationwide Claims-Based Study in Korea

The purpose of this study is to assess participant's overall well-being and the extent to which medical services are used by participants with non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC) who have undergone radical cystectomy (surgical procedure to remove entire urinary bladder). NMIBC is a type of bladder cancer in which cancer is confined to innermost lining of the bladder and MIBC is a type of bladder cancer in which cancer has grown deep into the thick muscle of the bladder.

Study groupRoleWhat they receive
Cohort A: NMIBC/MIBC CohortParticipants newly diagnosed with non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC) between September 1, 2015, and August 31, 2017 will be enrolled in Cohort A. Data will be collected using the health insurance review \& assessment (HIRA) claim database. No drug will be given as a part of the study.

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Cohort B: Number of Participants Reporting Post-Operative Complications Within 12 Months After Radical Cystectomy (RC) (time frame: Up to 12 months post RC procedure). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
