Detecting bladder cancer recurrence with a blood test

This study tests whether a simple urine test can accurately identify cancer in the bladder, ureters (tubes between kidneys and bladder), or renal pelvis (part of the kidney). You would provide urine samples before your planned surgery, and researchers will compare the urine test results to your actual tissue diagnosis after surgery.

This study tests a new non-invasive urine test (Xpert Bladder Monitor) to see if it can catch bladder cancer coming back early, reducing the need for frequent cystoscopy. It is for people with high-grade or high-risk non-muscle invasive bladder cancer who have had or are still having BCG treatment.

This study is testing a simple blood test that looks for cancer DNA in your blood. The goal is to see if it can accurately detect muscle-invasive bladder cancer or upper tract urothelial cancer.

This study collects urine samples to test UroAmp, a new genetic test that may help detect and monitor bladder cancer. It is for people with bladder cancer or blood in urine who want to help improve cancer detection.

This study uses a urine test to detect small amounts of cancer DNA (microscopic residual disease) after treatment, to see if it can catch a recurrence earlier than standard scans or cystoscopy. It includes four groups of people with different types and stages of urothelial cancer (in the kidney, ureter, or bladder) to see how well the test works for each group.

This trial tests a new blood test that looks for signs bladder cancer may be coming back in people with a recent history of bladder cancer. It may help by making surveillance easier, but you must still follow a scheduled bladder-check plan.
