CYFRA 21-1: A potential molecular marker for noninvasive differential diagnosis of urothelial carcinoma of bladder

Abstract

Establishing CYFRA 21-1 detection for noninvasive differential diagnosis of urothelial carcinoma (UC) of bladder would help to improve assessment and follow-up of patients, as well as to improve screening of high-risk groups. The study group comprised of 147 subjects including 72 patients with UC of bladder, 75 controls and 17 follow-up cases. The levels of CYFRA 21-1 in serum, urine and urinary cell lysate were estimated by high sensitivity ELISA. Our results indicate that urinary CYFRA 21-1 provides a high value of overall sensitivity for UC of bladder and is also useful even for detection of low grade tumors that might indicate possible earlier detection and treatment administration.
