Detection of Bladder Cancer by Microsatellite Analysis (MSA) of Urinary Sediment: Multi-Institutional Study



- Compare the sensitivity and specificity of microsatellite analysis (MSA) of urine
sediment with cystoscopy and urine cytology for detecting bladder cancer in
participants undergoing cystoscopy.


- Determine the temporal performance characteristics of MSA in urine sediment from these

- Determine which of the 15 individual markers or combination of markers that make up the
MSA test are most predictive of the presence of bladder cancer in these participants.

OUTLINE: This is a single-blind, multicenter, cohort study.

Urine and blood specimens are collected from all participants at baseline. Urine specimens
are examined using microsatellite analysis, urine cytology, and urinalysis. Patients in
groups 2 and 3 also undergo cystoscopy at baseline.

Patients in group 3 undergo cystoscopy, upper tract imaging (e.g., abdominal CT scan),
microsatellite analysis, urine cytology, and urinalysis every 3 months for 2 years in the
absence of progressive disease.

Microsatellite analysis, which identifies loss of heterozygosity using polymerase chain
reaction technique, is conducted for 15 markers: D4S243, D21S1245, FGA, D17S695, D16S476,
D9S171, IFN-A, D20S48, D13S802, D17S654, D16S310, THO1, D9S162, D9S747, and MBP.

PROJECTED ACCRUAL: A total of 500 participants (100 each for groups 1 and 2 and 300 for
group 3) will be accrued for this study.
