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).

Outcome Measures

Primary Outcomes (3)

  • 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)

    The 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.

    12 months after enrollment

  • 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)

    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.

    24 months after enrollment

  • 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)

Study Arms (2)

Patients who have selected bladder-sparing therapy

Patients with a diagnosis of recurrent high-grade NMIBC who have selected bladder-sparing therapy (BST)

Eligibility Criteria

Age18 Years+
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with a diagnosis of recurrent high-grade NMIBC who are considering second-line treatment will be approached for participation in this observational study in addition to their caregivers. Enrollment at each site will aim for a 2:1 ratio of participants selecting bladder-sparing therapy to radical cystectomy in order to ensure adequate enrollment of radical cystectomy patients. There will also be a qualitative sub-study that will include interviews of 50 patients and 25 caregivers recruited from the observational cohort study.

You may qualify if:

  • Adult 18 years of age or older; and
  • Presenting with high-grade NMIBC established by anatomic pathology as tumor stage classification Tis, Ta, or T1, and with:
  • Pathology documentation from any hospital/clinic/medical center, and
  • More than 50% urothelial carcinoma component in the specimen
  • History of high-grade NMIBC established by anatomic pathology as tumor stage classification Tis, Ta, or T1; and
  • Attempted or received induction BCG (at least 3 out of 6 instillations) at any point in time; and
  • In the previous 12 months, received at least one instillation of any intravesical agent (induction or maintenance) or one administration of systemic therapy for NMIBC treatment.

You may not qualify if:

  • Any plasmacytoid or small cell (neuroendocrine) component in the pathology (past or current presentation);
  • Previous history of cystectomy or radiation therapy for bladder cancer;
  • Previous history of muscle-invasive bladder cancer or metastatic bladder cancer;
  • Any history of upper tract urothelial carcinoma;
  • Incarcerated in a detention facility or in police custody (patients wearing a monitoring device can be enrolled) at baseline/screening;
  • Contraindication to radical cystectomy (e.g., American Society of Anesthesiologists (ASA) physical status of 4, patient not considered a radical cystectomy candidate due to comorbidity);
  • Contraindication to medical therapy (i.e., intolerant of all medical therapies);
  • Unable to provide written informed consent in English;
  • Unable to be contacted for research surveys;
  • Planning to participate in a Phase I or Phase II interventional clinical trial for NMIBC (unless in the control/comparator arm of a Phase II trial) or any blinded interventional trial for NMIBC.
