Examining the role of urinary microbiota in bladder cancer among Egyptian men

Profiling Urinary Microbiota in Male Patients With Bladder Cancer- An Exploratory Study.

Observational Theodor Bilharz Research Institute · NCT06289270

This study is testing how the bacteria in urine might be linked to bladder cancer in men to help find better ways to prevent and treat the disease.

What this trial studies

This observational study aims to investigate the relationship between urinary microbiota and bladder cancer in adult male patients. It will analyze urine and bladder tissue samples from both patients diagnosed with bladder cancer and healthy controls using advanced genomic sequencing techniques, including whole genomic sequencing and 16S rRNA sequencing. The goal is to identify specific microbial profiles that may contribute to the development of bladder cancer, which could lead to improved prevention, diagnosis, and treatment strategies.

Who should consider this trial

Good fit: Ideal candidates for this study are adult men over 18 years old who have been diagnosed with bladder cancer.

Not a fit: Patients who have undergone previous treatments such as radiotherapy or intravesical chemotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the role of microbiota in bladder cancer, potentially leading to new diagnostic and therapeutic approaches.

How similar studies have performed: While the role of microbiota in various cancers has been explored, this specific approach focusing on bladder cancer in Egyptian men is relatively novel.
