Evaluating Neutrophil-Lymphocyte Ratio in Bladder Cancer Treatment

Nordic Cystectomy Study I - Prospective Validation of Neutrophil/Lymphocyte Ratio as Predictor of Bladder Cancer Survival Risk After Radical Cystectomy for Bladder Cancer

Observational Turku University Hospital · NCT04523025

This study is testing if the neutrophil-lymphocyte ratio can help doctors better understand how muscle invasive bladder cancer patients will respond to treatment before they have surgery.

What this trial studies

This observational study focuses on patients diagnosed with muscle invasive bladder cancer who are planned to undergo radical cystectomy, with or without neoadjuvant chemotherapy. It aims to assess the neutrophil-lymphocyte ratio (NLR) as a potential prognostic marker to improve individual risk assessments and treatment planning. By analyzing the NLR in relation to treatment outcomes, the study seeks to enhance understanding of tumor response to chemotherapy and surgical interventions. The study will involve multiple centers across the Nordic countries to gather a comprehensive dataset.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years with histologically confirmed urinary bladder cancer scheduled for radical cystectomy.

Not a fit: Patients undergoing radical cystectomy for reasons other than bladder cancer or those unwilling to participate will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies and better prognostic assessments for patients with muscle invasive bladder cancer.

How similar studies have performed: While the specific approach of using NLR in this context may be novel, similar studies have shown promise in utilizing biomarkers for prognostic assessments in cancer treatment.
