  Purpose

RATIONALE: Drugs used in chemotherapy work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy (RT) uses high-energy x-rays to damage tumor cells. It is not yet known which regimen of combination chemotherapy plus radiation therapy with or without surgery is more effective in treating bladder cancer.

PURPOSE: Randomized phase II trial to study the effectiveness of two combination chemotherapy regimens and radiation therapy with or without radical cystectomy in treating patients who have stage II or stage III bladder cancer.

Primary Outcome Measures:
  • Treatment Completion Rate [ Time Frame: From randomization to 11 weeks ] [ Designated as safety issue: No ]
    Radiation therapy and chemotherapy per protocol or within acceptable variation guidelines based on central review. The study was designed for a two-sided binomial test with 87% power and a significance level of 0.05 with a null hypothesis of a 70% completion rate against the alternative 90% completion rate. For each arm, more than 34 out of 43 evaluable patients completing the treatment, would indicate to reject the null hypothesis for a better treatment completion rate. Fewer than 24 out 43 evaluable patients completing the treatment would indicate to reject the null hypothesis for a worse treatment completion rate. Otherwise, the conclusion would be that there is not enough evidence to reject the null hypothesis of a 70% completion rate in either direction.


Secondary Outcome Measures:
  • Complete Response After Induction [ Time Frame: From randomization to eight weeks ] [ Designated as safety issue: No ]
    Complete response requires the absence of any tumor in the tumor-site biopsy specimen or elsewhere and a bimanual exam that does not indicate the presence of a tumor mass.

  • Bladder-intact Survival [ Time Frame: From the date of randomization to the time of cystectomy, death or last follow-up. Patients are followed until death. Analysis occurs at time of primary outcome measure, approximately eight years from study start. ] [ Designated as safety issue: No ]
    Bladder-intact survival was measured from the date of randomization to occurrence of cystectomy or death. Five-year rates were estimated using the Kaplan-Meier method.

Detailed Description:

OBJECTIVES:

  • Estimate the safety and tolerability of induction paclitaxel, cisplatin, and radiotherapy or fluorouracil, cisplatin, and radiotherapy followed by consolidation chemoradiotherapy or radical cystectomy and adjuvant gemcitabine, paclitaxel, and cisplatin in patients with operable stage II or III bladder cancer.
  • Estimate the efficacy of these regimens, in terms of complete response, in patients who have undergone prior transurethral resection (TUR).
  • Estimate the efficacy of these regimens after TUR, in terms of preserving the native tumor-free bladder 5 years after therapy, in these patients.
  • Estimate the function of the preserved bladder in patients treated with these regimens after TUR.
  • Determine the value of tumor histopathologic, molecular genetic, and DNA content parameters as possible prognostic factors for initial tumor response and recurrence-free survival in patients treated with these regimens.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to T stage (T2 vs T3/T4 ). Patients are randomized to one of two treatment arms.

  • Induction therapy (weeks 1-3):

    • Arm I: Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15 and cisplatin IV over 1 hour on days 1-3, 8-10, and 15-17. Patients also receive pelvic radiotherapy twice daily on days 1-5, 8-12, and 15-17.
    • Arm II: Patients receive fluorouracil IV over 24 hours on days 1-3 and 15-17 and cisplatin IV over 1 hour on days 1-3, 8-10, and 15-17. Patients also receive pelvic radiotherapy as in arm I.

Patients in both arms who achieve complete response after induction therapy proceed to consolidation therapy on week 8. Patients with operable pT1 or worse tumor response proceed to radical cystectomy on week 9.

  • Consolidation therapy (weeks 8 and 9):

    • Arm I: Patients receive paclitaxel IV over 1 hour on days 1 and 8 and cisplatin IV over 1 hour on days 1, 2, 8, and 9. Patients also receive pelvic radiotherapy twice daily on days 1-5 and 8-10.
    • Arm II: Patients receive 5-FU IV over 24 hours on days 1-3 and 8-10 and cisplatin as in arm I. Patients also receive radiotherapy as in arm I.
  • Adjuvant chemotherapy (weeks 21-33 or 17-29): Beginning 12 weeks after consolidation therapy or 8 weeks after radical cystectomy, patients receive gemcitabine IV over 30-60 minutes, paclitaxel IV over 1 hour, and cisplatin IV over 1 hour on days 1 and 8. Treatment repeats every 3 weeks for 4 courses.

Patients are followed every 3 months for 1 year, every 4 months for 1 year, every 6 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 96 patients (48 per treatment arm) will be accrued for this study within 3 years.
