Is this trial a fit for you?

Likely a good fit

Ideal candidates include adult patients with locally advanced, inoperable, or metastatic renal cell carcinoma or urothelial carcinoma who are starting their first-line systemic treatment.

Probably not a fit

Patients with early-stage or operable renal cell carcinoma or urothelial carcinoma may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This project aims to establish a national, prospective, longitudinal cohort study in Germany to document uniform data on the characteristics, molecular diagnostics, treatments, and disease progression of patients with advanced renal cell carcinoma and urothelial cancer. The registry will follow patients for up to three years for renal cancer and two years for bladder cancer, collecting comprehensive data on treatments, outcomes, and patient-reported quality of life. It will also create a decentralized biobank to support future research in these cancers.

Why it matters

Potential benefit: If successful, this registry could enhance understanding of treatment patterns and improve patient outcomes for those with advanced renal cell carcinoma and urothelial cancer.

How similar studies have gone: Other observational studies have successfully established cancer registries, indicating that this approach has potential for meaningful contributions to cancer treatment understanding.
