Diagnostic Evaluation of Urine DNA Methylation/Somatic Mutation Profiling for the Detection of Urothelial Carcinoma

Diagnostic Evaluation of Urine DNA Methylation/Somatic Mutation Profiling for the Detection of Urothelial Carcinoma

Clinical trial to evaluate the performance characteristics(sensitivity and specificity) of AnchorDx's urine DNA methylation/somatic mutation profiling assay for detecting urothelial carcinoma compared to pathology in patients.

This is a prospective study that involves 11 centers in China and 1200 participants. The assay analyzes the DNA methylation/somatic mutation profiles of bladder cancer-specific biomarkers non-invasively using urine specimens collected before invasive diagnosis/treatment. The performance characteristics(sensitivity and specificity) of the assay for detection of urothelial carcinoma is evaluated in comparison to pathology or cystoscopy.

Inclusion Criteria:

1. Urothelial carcinoma group:

   • Any male or female patient aged 18 or older.
   • Able to provide urine specimen (100ml for both first void and non-first-void urine) before treatments.
   • Diagnosed with incident or recurrent urothelial carcinoma (including bladder/ureter/renal pelvis) by surgery.

2. interference group:

   • Any male or female patient aged 18 or older.
   • Able to provide urine specimen (100ml for both first void and non-first-void urine) before treatments.
   • Diagnosed with incident or recurrent bladder cancer other than urothelial carcinoma (including bladder squamous cell carcinoma/bladder adenocarcinoma/other bladder-related cancers/prostate cancer/rectal cancer) by surgery.

3. Control group:

   • Any male or female patient aged 18 or older.
   • Able to provide urine specimen (100ml for both first void and non-first-void urine) before treatments.
