Microsatellite analysis (MSA) of bladder cancer detection requires a comprehensive analysis of up to 15–20 markers based on amplifying and interpreting many individual MSA markers, which can be technically challenging. To develop fast, efficient, standardized, and less costly MSA to detect bladder cancer, we developed three multiplex polymerase chain reaction (PCR) based MSA assays, all of which were analyzed by a genetic analyzer. First, we selected 16 MSA markers based on nine publications. We developed MSA assays based on triplet or three-tube-based multiplex PCR (Triplet MSA assay) using samples from Johns Hopkins University (JHU Sample, first set of samples) . In the second set of samples (samples from six cancer patients and fourteen healthy individuals), our Triplet Assay with 15 MSA markers correctly predicted all 6/6 cancer samples to be cancerous and 14/14 healthy samples to be healthy. Although we could improve our report with more clinical information from patient samples and an increased number of cancer patients, our overall results suggest that our Triplet MSA Assay combined with a genetic analyzer is a potentially time-and cost-effective genetic assay for bladder cancer detection and has potential use as a dependable assay in patient care.  \nKeywords: bladder cancer; loss of heterozygosity; microsatellite instability; triplet MSA assay  \n1. Introduction  \nMicrosatellite instability (MSI) is a molecular tumor phenotype resulting from genomic hypermutability and manifested by genome-wide variations in the length of microsatellite sequences. As a familiar part of colon cancer syndrome, MSI is common in individuals with Lynch syndrome [1–3] . However, since its discovery, MSI has been a generalized phenomenon in a wide spectrum of sporadic cancers [4–8] . The underlying mechanisms of sporadic cancers may be based on epigenetic mechanisms, namely MLH1 methylation. The accumulation of frameshift mutations in tumor-associated genes is the most detrimental outcome of MSI, either in inherited or sporadic tumors. These mutations can activate crucial pathways promoting human carcinogenesis. Determining whether a tumor exhibits microsatellite instability (MSI) is useful in identifying patients with hereditary non-polyposis colorectal cancer and sporadic gastrointestinal ","cbCaiqt60iGQP9S8","https://ap.wps.com/l/cbCaiqt60iGQP9S8","pdf",457685,13,"English","# Abstract\n# 1.
