Design outcomes

Primary

MeasureTime frame
Primary endpoint: Discrimination of Ctrl with cancer patients using FDS. Validation of FDS on cancer status between the patients with PC vs. Ctrl, and between the patients with non-PC (BC, UTUC, RCC,) vs. Ctrl. Sample size calculation for primary endpoints (http://www.biosoft.hacettepe.edu.tr/easyROC/ ver.1.3.1) The sample size for non-PC non-inferiority margin <5% AUC for standard test : 0.967 Sample size calculation for testing noninferiority of a new test to a standard test ----------------------------------------- Input: ----------------------------------------- Type I error : 0.025 Power : 0.9 AUC for standard test : 0.967 Allocation ratio : 2 ----------------------------------------- Output: ----------------------------------------- Case : 139 Control : 287 Total : 417 ----------------------------------------- The sample size for PC non-inferiority margin <5% in AUC: AUC for standard test : 0.974 ----------------------------------------- Input: ----------------------------------------- Type I error : 0.025 Power : 0.9 AUC for standard test : 0.974 Allocation ratio : 2 ----------------------------------------- Output: ----------------------------------------- Case : 102 Control : 204 Total : 306 -----------------------------------------

Secondary

MeasureTime frame
Secondary endpoints: Prognostic value Validation of FDS on prognosis prediction in urological cancer patients between the FDS-high vs. -low. FDS-high and -low were defined >2.3 in non-PC and >3.3 in PC, respectively. Sample size calculation for secondary endpoints Overall survival (OS) between the FDS-high and -low. FDS-high: FDS>2.3 in non-PC patients and >3.3 in PC patients FDS-low: FDS =<2.3 in non-PC patients and =<3.3 in PC patients Our sample size calculations were based on the primary outcome of OS. Our previous study suggested the 2-year OS in patients with FDS-high and -low were 73% and 96%, respectively. Using 90% power and 2.5% two-sided alpha, the sample size to illustrate the superiority of FDS-high and -low was 68 participants per arm (an allocation ratio 1:1, total n = 136) will be required. Accounting for 15% withdrawal/loss to follow-up, 156 (78 vs. 78) participants will need to be recruited.
