The presence of circulating tumor cells does not predict extravesical disease in bladder cancer patients prior to radical cystectomy

Due to imprecise clinical staging, the finding of extravesical and node-positive disease at the time of radical cystectomy (RC) for patients with clinically localized bladder cancer is not uncommon. Circulating tumor cells (CTCs) have been shown to be present in the peripheral blood of patients with metastatic urothelial carcinoma. The object of this study was to evaluate the ability of CTCs to predict extravesical disease in bladder cancer...
