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.

Who should consider this trial

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.

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

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

Inclusion Criteria:

Cohorts aRCC and aUBC (prospective)

* Female and male patients with aRCC or aUBC (locally advanced, inoperable or metastatic)

* Age ≥ 18 years at the time of surgery.

Exclusion Criteria:

Cohorts aRCC and aUBC (prospective)

* No systemic treatment for aRCC or aUBC

Cohort High-risk MIUC (prospective and retrospective)

* Partial cystectomy or partial nephrectomy of the primary tumor as definitive therapy
* Metastatic disease (M1) at the time of surgery
