S0337, Gemcitabine After Surgery in Treating Patients With Newly Diagnosed or Recurrent Bladder Cancer
- Registration Number
- NCT00445601
- Lead Sponsor
- SWOG Cancer Research Network
- Brief Summary
RATIONALE: Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving gemcitabine directly into the bladder after surgery may kill more tumor cells. It is not yet known whether giving gemcitabine directly into the bladder is more effective than a placebo in treating bladder cancer.
PURPOSE: This randomized phase III trial is studying gemcitabine to see how well it works when given directly into the bladder compared with a placebo after surgery in treating patients with newly diagnosed or recurrent bladder cancer.
- Detailed Description
OBJECTIVES:
Primary
* Compare the efficacy of a single intravesical instillation of gemcitabine hydrochloride vs placebo immediately after transurethral resection of the bladder tumor (TURBT) in preventing recurrence at 2 years in patients with grade 1 or 2 superficial transitional cell cancer of the bladder.
Secondary
* Compare whether a single instillation of intravesical gemcitabine hydrochloride can improve the time to progression to muscle invasive disease vs placebo in these patients.
* Compare the qualitative and quantitative toxicities of these regimens in these patients.
* Compare whether treatment with post-TURBT intravesical instillation of gemcitabine vs placebo results in reduced long-term morbidity in patients, as defined by requirement for fewer TURBTs, courses of traditional intravesical therapies, and surveillance cystoscopies over 4 years.
Tertiary
* Assess whether performing a combination of molecular and/or cytologic diagnostic marker tests, including NMP-22 Bladder Chek and BTA Stat every 3 months, can predict recurrence as accurately as cystoscopy alone in these patients.
OUTLINE: This is a randomized, double-blind, multicenter study. Patients are stratified according to disease status (first occurrence vs recurrent disease) and number of tumor sites (1 vs ≥ 2). Patients are randomized to 1 of 2 treatment arms.
All patients undergo transurethral resection of the bladder tumor. Within 3 hours, patients receive intravesical therapy according to their randomized arm.
* Arm I: Patients receive intravesical gemcitabine hydrochloride over 1 hour.
* Arm II: Patients receive intravesical placebo over 1 hour. Urine is collected at baseline and then every 3 months for 2 years for research studies including the NMP-22 Bladder Chek and BTA Stat test.
After completion of study treatment, patients are followed every 3 months for 2 years and then every 6 months for 2 years.
PROJECTED ACCRUAL: A total of 340 patients will be accrued for this study.

- Primary Outcome Measures
Name Time Method Disease Recurrence Rate Up to 2 Years Percentage of patients who experienced a recurrence of grade 1 or 2 superficial transitional cell cancer of the bladder between the date of registration and 24 months. Disease recurrence considered to occur at date of first observation of recurrent disease subsequently confirmed by biopsy. Patients without recurrence were censored at the time of their last cystoscopy.
- Secondary Outcome Measures
Name Time Method Rate of Disease Worsening Over 2 Years Up to 2 years Compare whether treatment with post-TURBT intravesical instillation of gemcitabine vs placebo results in reduced long-term morbidity in patients, as defined by requirement for fewer TURBTs, courses of traditional intravesical therapies, and surveillance cystoscopies over 4 years.
Rate of Progression to Muscle Invasive Disease at 4 Years 4 years From date of registration to date of diagnosis of progressive disease. Censor at date of last disease assessment for those without progression.
Compare Qualitative and Quantitative Toxicities Between the Treatment Arms Up to 4 years after Transurethral Resection of Bladder Tumor (TURBT) Number of patients with Grade 3 through Grade 5 adverse events that are related to study drug
