Abstract：
OBJECTIVES:To evaluate three urine markers, BTA stat, cytology, and urinary survivin levels, in the spinal cord injury (SCI) population. The incidence of bladder cancer in patients with SCI is up to 20 times greater than in the general population. However, bladder cancer biomarkers have not been assessed in this population. METHODS:Between April 1999 and April 2004, 457 patients with SCI enrolled at the HealthSouth Harmarville Rehabilitation Spinal Cord Clinic donated their urine to our SCI urine repository. BTA stat tests and the survivin assay were performed according to published standards. Cytology specimens were sent to our cytopathology laboratory for analysis. RESULTS:A total of 1075 urine specimens from 457 patients were analyzed. Of the 1073 BTA stat tests, 119 showed positive reactions and 954 were negative. In the survivin assays, 47 samples had a score of 1, 38 a score of 2, and 9 a score of 3. No cytology specimens were noted to have malignant cells. During the past 5 years, 3 patients were diagnosed with bladder cancer by cystoscopy and treated for superficial disease. For these patients, none of these three tests (BTA stat, survivin assay, and cytology) was positive before the diagnosis of bladder cancer. CONCLUSIONS:The BTA stat, survivin assay, and urine cytology were unable to predict bladder cancer cases in our cohort of patients with SCI. Cystoscopy, therefore, remains the gold standard for bladder cancer surveillance in patients with SCI.
