Stepwise Application of Urine Markers to Detect Tumor Recurrence in Patients Undergoing Surveillance for Non-Muscle-Invasive Bladder Cancer

Table 4

(a) Performance of stepwise testing of cytology and uCyt+. High-risk tumors were defined as tumors showing at least one of the following features: pT1 or higher, G3, carcinoma in situ (Cis). PPV: positive predictive value. NPV: negative predictive value. (b) Performance of stepwise testing of cytology and fluorescence in situ hybridization (FISH). High-risk tumors were defined as tumors showing at least one of the following features: pT1 or higher, G3, carcinoma in situ (Cis). PPV: positive predictive value. NPV: negative predictive value.
