This study investigates a blood test called a "liquid biopsy" to find cancer cells in the blood of bladder cancer patients. Bladder cancer is a disease where cells in the bladder grow uncontrollably. This study aims to see if the test can reliably detect these cancer cells.
The study uses a special system called a magneto-fluidic system to capture circulating tumor cells from blood samples. This system is being tested and improved to see if it can work well for patients with advanced bladder cancer and might be used for patients at earlier stages.
- Who can participate: Participants must have advanced urothelial bladder cancer, either metastatic or muscle invasive. Both untreated patients and those who had treatment more than 3 weeks before blood collection can join.
- Study details: Participants will have their blood tested using the investigational liquid biopsy to detect cancer cells. Blood samples will be collected once every two weeks over a period of two months. The test uses a magneto-fluidic system to capture circulating tumor cells from the blood. Participants may also undergo additional imaging procedures as part of the study.
