Conditions

Non-muscle Invasive Bladder Cancer

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

DIAGNOSTIC_TESTCxBladder Monitor

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.

DIAGNOSTIC_TESTCystoscopy

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.

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.

Design outcomes

Primary

MeasureTime frameDescription
Preference for CxBladder Monitor compared to cystoscopyUp to 6 monthsPatient 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

MeasureTime frameDescription
Patient satisfactionUp to 6 monthsPatient 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-24Up to 6 monthsThe 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 monthsHealth-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 costsUp to 6 monthsAssessed 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 monthsError 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.
