S0219, Combination Chemotherapy Followed By Observation or Surgery in Patients With Stage II or Stage III Cancer of the Urothelium
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells and decrease the need for surgery.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy followed by observation or surgery to remove the bladder (cystectomy) in treating patients who have stage II or stage III cancer of the urothelium.

- Pathologic Complete Response Rate by Transurethral Resection of Bladder Tumor (TURBT) and Imaging Studies After Chemotherapy [ Time Frame: up to 12 weeks after registration (assessed within 8 weeks after completion of 3 cycles of chemotherapy ) ]Pathologic complete response (CR) is defined as absence of viable tumor in the TURBT specimen. Stable/No Response is defined as at least some disease evaluation tests were done (same tests as baseline) and status does not qualify for CR or Progression. Progression is defined as one or more of the following must occur: unequivocal progression of disease in the opinion of the treating physician. Appearance of any new lesion/site. Death due to disease without documented progression or symptomatic deterioration.
- Overall Survival (OS) [ Time Frame: 0-2 years ]Overall survival is defined from the date of registration to date of death from any cause
- Number of Patients With Grade 3 Through Grade 5 Adverse Events That Are Related to Study Drug [ Time Frame: Patients were assessed for adverse events at weeks 1, 2, 4, 5, 7, 8, and following surgery ]Adverse Events (AEs) are reported by the NCI Common Terminology Criteria for Adverse Events (CTCAE) version 2.0. For each patient, worst grade of each event type is reported. Grade 3 = Severe, Grade 4 = Life-threatening, Grade 5 = Fatal.

- Determine the pathologic complete response of patients with stage II or III transitional cell cancer of the urothelium treated with neoadjuvant gemcitabine, paclitaxel, and carboplatin followed by observation or immediate cystectomy.
- Determine, preliminarily, if molecular markers predict response, survival, and tumor recurrence in patients treated with these regimens.
- Determine recurrence rates and cystectomy-free survival of patients who choose observation after an initial response to neoadjuvant chemotherapy.
- Compare the survival of patients treated with neoadjuvant chemotherapy followed by cystectomy vs observation.
- Determine the feasibility, tolerability, and toxicity of these regimens in these patients.
OUTLINE: This is a multicenter study.
Patients receive gemcitabine IV over 30 minutes and paclitaxel IV over 30 minutes on days 1 and 8 and carboplatin IV over 30 minutes on day 1. Treatment repeats every 3 weeks for 3 courses in the absence of disease progression or unacceptable toxicity.
Within 4-8 weeks after completion of neoadjuvant chemotherapy, patients undergo a third transurethral resection of bladder tumor.
Patients with T0 disease after neoadjuvant chemotherapy may choose to undergo observation. These patients undergo cystoscopies with biopsies every 3 months for 1 year, every 4 months for 1 year, and then every 6 months until disease progression.
Patients with T1 disease or greater after neoadjuvant chemotherapy undergo immediate cystectomy. Patients with T0 disease may also choose this option. Patients undergoing immediate cystectomy are followed every 6 months for 2 years and then annually for 3 years.
PROJECTED ACCRUAL: A total of 95 patients will be accrued for this study within 2 years.
