Bladder cancer is the second most common genitourinary tumor and is a significant cause of morbidity and mortality. To find the noninvasive tumor marker for bladder cancer is still a challenge. Recently, the circulating cell-free DNA had been used for detection of some tumors. However, most of these studies selected the blood sample as the free DNA source. The purpose of this thesis is to develop and evaluate the more noninvasive method and tumor marker for bladder cancer detection, especially for the cell-free DNA. Three directions were addressed as followed: 1). urine cell-free DNA makers such as creatinine-adjusted cell-free DNA concentration, 2). DNA integrity (DNA length) and 3). Promoter hypermethylation for DNA repair genes. First, creatinine-adjusted urine cell-free DNA concentration was quantified via real time PCR. The real time PCR-based detection is based on detection large fragment cell-free DNA. Real time PCR-based urine cell-free DNA concentration of bladder cancer patients was higher than controls. Mean concentrations of 36 bladder cancer patients and 93 controls which detected by real time PCR were 14.98 and 1.07 pg/
