A Prospective, Multi-centre, Single-blinded Study of UroCAD for Urothelial Carcinoma Diagnosis and Follow-up

Urothelial carcinoma (UC) is common malignancy and is considered to be one of the costliest cancers. The traditional diagnostic methods of UC present with some shortcomings. For example, the specificity of CTU remains low while cystoscopy is invasive and expensive. Therefore, a noninvasive diagnostic method with high accuracy is urgently needed. Our previous study has proved that UroCAD, which is able to detect chromosomal aberrations of the urine exfoliated cells, is a reliable method in diagnosing UC with sensitivity and specificity of 82.5% and 96.9%, respectively. But its potential in UC patient follow-up hasn\'t been assessed yet and the the accuracy of UroCAD in detecting UC still need to be further validated. The investigators here intended to investigate whether UroCAD can be used in UC patient follow-up and further validate the accuracy of UroCAD in diagnosing UC.
