Brief summary

Bladder cancer is the most common urinary tract cancer and the 5th most common cancer in the US (1). Yet bladder cancer research is underfunded relative to other common cancers. As a result, bladder cancer care is prone to evidence gaps that produce decision uncertainty for both patients and clinicians. The Comparison of Intravesical Therapy and Surgery as Treatment Options (CISTO) for Bladder Cancer Study has the potential to fill these critical evidence gaps, change care pathways for the management of non-muscle-invasive bladder cancer (NMIBC), and provide for personalized, patient-centered care. The purpose of CISTO is to conduct a large prospective study that directly compares the impact of medical management versus bladder removal in recurrent high-grade NMIBC patients with Bacillus Calmette-Guerin (BCG) failure on clinical outcomes and patient and caregiver experience using standardized patient-reported outcomes (PROs).

Detailed description

Most bladder cancer patients (74%) present with NMIBC where the cancer is limited to the lining or support layer of the bladder. High-grade NMIBC is treated initially with endoscopic resection and intravesical immunotherapy, followed by bladder instillations of BCG. Most patients with high-risk, high-grade NMIBC are able to retain their bladders and avoid more invasive treatments. However, 24-61% of patients will have their cancers recur within 12 months of treatment with BCG (BCG failures), and they have limited treatment options. National guidelines recommend consideration between two alternatives: additional medical management and radical cystectomy (removal of the bladder). Selecting between these options involves weighing the risk of progression of bladder cancer and loss of a window of potential cure versus the risk of morbidity and loss of quality of life (QOL) with bladder removal. This complex decision-making engages patients and their caregivers, who may be impacted by the urinary, sexual, and bowel dysfunctions that can occur with NMIBC treatment. The investigators will evaluate this research question on a large scale in real world practice settings including academic and community-based practices and examine patient-centered outcomes. The investigators have engaged stakeholders with diverse perspectives relevant to this research question, including patients, caregivers, national patient advocacy organizations, national medical specialty organizations, guideline developers, health care payers, and industry. By engaging broad expertise relevant to this research question, the investigators will ensure that the study results will help NMIBC patients whose cancer recurs after BCG treatment make more informed decisions that improve the health outcomes that are important to them. CISTO is an observational study that will not affect the treatment that patients chose. Patient surveys will occur at study entry and at follow-up assessments for up to four years. There will also be a qualitative sub-study that will include interviews of approximately 50 patients and 25 caregivers recruited from the observational cohort study.

MeasureTime frameDescription
Patient-reported Quality of Life as Measured by the Physical Function Scale of the European Organization for Research and Treatment of Cancer Quality-of-Life-Questionnaire-Core-30 (EORTC QLQ-C30)12 months after enrollmentThe primary outcome of patient-reported quality of life is measured by the EORTC QLQ-C30 Physical Function scale. The scale ranges in score from 0 to 100, with higher function scores indicating better health. Scale score is calculated by transforming individual item scores into a 0 to 1 scale, taking the mean, and multiplying by 100. Each scale requires responses for at least 50% of the items in order to be calculated.

MeasureTime frameDescription
Patient Overall Survival12 months after diagnosis of recurrent high-grade non-muscle invasive bladder cancer, up to 12 months post enrollmentThe evaluation of the effect of treatment choice on overall survival. Survival times were calculated from the date of diagnosis of recurrent high-grade non-muscle invasive bladder cancer to the event (death). Censoring occurred at the last electronic health record review or date of death.
Patient Self-reported Urinary Health as Measured by the Bladder Cancer Index Urinary Summary Score12 months after enrollmentThe evaluation of the effect of treatment choice on patient-reported urinary health, as measured by the Bladder Cancer Index (BCI). The BCI consists of 36 items, with 4- or 5-point Likert response scales, covering 3 primary domains: urinary, bowel, and sexual. For each domain a summary score is constructed from the items used to calculate the two subscale scores (function and bother). Scores are calculated by transforming item responses into a 0 to 100 scale and calculating the mean of the standardized items. Higher scores indicate better health status. To calculate a score, a minimum of 80% completed items is required.
Patient Self-reported Sexual Health as Measured by the Bladder Cancer Index Sexual Summary Score12 months after enrollmentThe evaluation of the effect of treatment choice on patient-reported sexual health, as measured by the Bladder Cancer Index (BCI). The BCI consists of 36 items, with 4- or 5-point Likert response scales, covering 3 primary domains: urinary, bowel, and sexual. For each domain a summary score is constructed from the items used to calculate two subscale scores (function and bother). Scores are calculated by transforming item responses into a 0 to 100 scale and calculating the mean of the standardized items. Higher scores indicate better health status. To calculate a score, a minimum of 80% completed items is required.

Patient Self-reported Financial Distress as Measured by the Comprehensive Score for Financial Toxicity (COST)12 months after enrollmentThe evaluation of the effect of treatment choice on patient-reported financial distress, as measured by the Comprehensive Score for Financial Toxicity (COST). The COST questionnaire consists of 11 items, each scored on a 5-point Likert scale from zero to four. After reversing some items as indicated in the scoring manual (by reversing the sign on the original zero to four score and adding four), all item response scores are summed into a single financial toxicity score ranging from 0 to 44, with higher scores indicating greater financial wellbeing. Each subscale requires responses for at least 50% of the items in that subscale in order to be calculated. Item nonresponse is accounted for by substituting the mean of the completed items in the subscale.

Patient Self-reported Bowel Health as Measured by the Bladder Cancer Index Bowel Summary Score

The evaluation of the effect of treatment choice on patient-reported bowel health, as measured by the Bladder Cancer Index (BCI). The BCI consists of 36 items, with 4- or 5-point Likert response scales, covering 3 primary domains: urinary, bowel, and sexual. For each domain a summary score is constructed from the items used to calculate two subscale scores (function and bother). Scores are calculated by transforming item responses into a 0 to 100 scale and calculating the mean of the standardized items. Higher scores indicate better health status. To calculate a score, a minimum of 80% completed items is required.

Patient Self-reported Financial Distress as Measured by the Comprehensive Score for Financial Toxicity (COST)

The evaluation of the effect of treatment choice on patient-reported financial distress, as measured by the Comprehensive Score for Financial Toxicity (COST). The COST questionnaire consists of 11 items, each scored on a 5-point Likert scale from zero to four. After reversing some items as indicated in the scoring manual (by reversing the sign on the original zero to four score and adding four), all item response scores are summed into a single financial toxicity score ranging from 0 to 44, with higher scores indicating greater financial wellbeing. Each subscale requires responses for at least 50% of the items in that subscale in order to be calculated. Item nonresponse is accounted for by substituting the mean of the completed items in the subscale.
