Non-muscle Invasive Bladder Cancer
Conditions
Brief summary
The purpose of this study is to evaluate patient-reported preference for urine based molecular testing (CxBladder Monitor) compared to cystoscopy for patients on surveillance for Nonmuscle Invasive Bladder Cancer (NMIBC). Urine based molecular testing involves noninvasive testing of a urine sample for biomarkers associated with disease recurrence. Cystoscopy is an examination of the bladder and urethra using a thin tube like instrument that is inserted into the urethra.
Interventions
CxBladder Monitor (CxbM) is an FDA-approved genomic biomarker test specifically designed for patients undergoing surveillance for NMIBC. The non-invasive urine test quantifies 5 measured biomarker genes (MDK, HOXA13, CDC2 (CDK1), IGFBP5, CXCR2) and incorporates this information into an algorithm to detect the presence or absence of bladder cancer.
Cystoscopy is the most common way surveillance has been performed for NMIBC. Cystoscopy is a procedure that allows your doctor to examine the lining of your bladder and the tube that carries urine out of your body (urethra). A hollow tube (cystoscope) equipped with a lens is inserted into your urethra and slowly advanced into your bladder.

Eligibility
Inclusion criteria
* Male or female with a history of histologically confirmed nonmuscle invasive bladder cancer (NMIBC) who have at least 6 months of disease-free survival from last recurrence. * Able to provide urine for testing and comply with study protocol. * Have an email address and be willing to complete surveys online.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Preference for CxBladder Monitor compared to cystoscopy | Up to 6 months | Patient preference will be assessed based on the Preference Questionnaire (PQ) after completion of the study cross-over period (after both methods of testing have been experienced). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient satisfaction | Up to 6 months | Patient satisfaction will be assessed based on the Satisfaction Questionnaire (SQ) after completion of each test at 3 and 6 months. |
| Change in symptoms and function - EORTC NMIBC-24 | Up to 6 months | The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Non-Muscle-Invasive Bladder Cancer (EORTC NMIBC-24) will be used to assess Health-related quality of life. The questionnaire consists of 24 items scored on a four-point Likert scale ranging from 1 (not at all) to 4 (very much), with the exception of the global health status items, which employ a seven-point scale ranging from 1 (very poor) to 7 (excellent). Higher scores are interpreted as more symptom burden, with exception of the sexual function and sexual enjoyment sections, where higher scores represent better functioning. |
| Fear of Cancer Recurrence Inventory- Short Form (FCRI-SF) | Up to 6 months | Health-related quality of life will be assessed based on the Fear of Cancer Recurrence Inventory- Short Form (FCRI-SF) at baseline, 3 months (within 1 week of test), and 6 months (within 1 week of test). The nine-item FCRI evaluates the presence and severity of intrusive thoughts associated with FCR. Each item is rated on a Likert scale ranging from 0 ("not at all" or "never") to 4 ("a great deal' or "all the time"). A higher score indicates higher levels of FCR. |
| Financial costs | Up to 6 months | Assessed by patient responses to questions about missed work and time missed from usual activities. |
| Error rate identifying recurrent nonmuscle invasive bladder cancer (NMIBC) | Up to 6 months | Error rate for CxBladder is defined as the proportion of patients who have a negative CxBladder at 3 months but have a recurrence identified on cystoscopy at 6 months for patients in arm A. The error rate for cystoscopy is defined as the proportion of patients who have a negative cystoscopy at 3 months but have a positive CxBladder at 6 months that is subsequently confirmed by cystoscopy for patients in arm B. |
