External Validation of Uromonitor as a Biomarker for Optimization of NMIBC Management by the CUETO Group

Pharmalink600 enrolled

Overview

Independent validation of Uromonitor as a non-invasive biomarker of recurrence of Non Muscle Invasive Bladder Cancer

This study is intended as an independent validation series for previous studies performed in several European centers with less statistical power. We expect to validate the results from a previous study, reaching the sensitivity and specificity data obtained at generation and first external validation papers. The overall goal of this study is to perform a bigger external multicenter validation study to evaluate the sensitivity, specificity, NPV and PPV of Uromonitor for the detection of bladder cancer recurrence in an independent series of patients. The specific objectives of this study protocol are the following: Main endpoint: • To evaluate the clinical sensitivity, specificity, NPV and PPV of Uromonitor in the detection of bladder cancer recurrence in patients previously diagnosed (over the last 3 months to 2 years) of NMIBC, treated or not, by testing a total of 600 patients (EVALUATION-CUETO Study)

Eligibility

Sex: ALLMin age: 22 Years

Medical Language ↔ Plain English

Inclusion Criteria: Main Outcome: * Age \>22. * Patients with a history of non-muscle invasive bladder cancer (any risk group, any intravesical adjuvant treatment received) over the last 3 months to 2 years, initial or recurrent, undergoing regular cystoscopic surveillance. The criteria for cystoscope FU schedule has been already described in Methods following EAU 2022 Guidelines´ recommendations and related to initial NMIBC risk grouping. * Patient must be able to provide at least 10 ml of urine. * Additional 10 ml of urine needs to be collected for cytology. * Patients must be able to provide informed consent 2.- Subgroup analysis (secondary Objective 1): * Age \>22 * Patients with a history of primary non-muscle invasive bladder cancer with presence of CIS over the last 3 months to 3 years, and previously treated with BCG undergoing regular cystoscopic surveillance. * Patient must be able to provide at least 10 ml of urine. * Additional 10 ml of urine needs to be collected for cytology. * Patients must be able to provide informed consent. 3.- Subgroup analysis (secondary Objective 2): * Age \>22 * Patients included in both previous groups, having a positive Uromonitor® test and a negative cystoscopy to be followed by two years as previously described depending on initial NMIBC risk group. The rest of the patients will also be followed 2 years to detect later recurrences/progression figures. Exclusion Criteria: * Patients who are unable to provide the minimum amount of urine needed to perform one test. * Patients planning to undergo radical cystectomy or chemotherapy, radiation for UC * Patients at risk for non-definitive information derived from the cystoscope due to different conditions: * Not possible to ascertain informative cystoscope due to intolerance to the procedure * Presence of bladder stone * Presence of entero-vesical fistulae * Presence of vesico-vaginal fistulae * Non informative cystoscope due to macroscopic haematuria or cloudy urine * Other conditions avoiding a clear tumour rule-out cystoscope

Outcomes

Primary Outcomes

Sensitivity, specificity, NPV and PPV of Uromonitor

To evaluate the clinical sensitivity, specificity, NPV and PPV of Uromonitor in the detection of bladder cancer recurrence in patients previously diagnosed (over the last 3 months to 2 years) of NMIBC, treated or not

Time frame: 2 years after diagnosis

Secondary Outcomes

Statistics in CIS, treated or not

To evaluate the clinical sensitivity and specificity of Uromonitor in the detection of bladder cancer recurrence in patients previously diagnosed (over the last 3 months to 3 years) of NMIBC with carcinoma in situ (CIS) associated and treated with BCG

Time frame: 2 years after diagnosis

Early diagnostics

To check if Uromonitor can provide some early diagnostics of NIMBC by following for two years a group of false positive patients of both previous groups (Uromonitor Positive / Cystoscopy Negative)

Time frame: 4 years after diagnosis
