Spots Global Cancer Trial Database for Radiation Therapy or Surgery in Treating Patients Receiving Chemotherapy for Bladder Cancer

Study Description

Brief Summary: RATIONALE: Drugs used in chemotherapy, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether radiation therapy is more effective than surgery in treating patients with bladder cancer. PURPOSE: This randomized phase III trial is studying radiation therapy to see how well it works compared with surgery in treating patients with bladder cancer who are receiving chemotherapy.

Detailed Description: OBJECTIVES: Primary * To determine the feasibility and patient acceptability of radical cystectomy vs selective bladder preservation (SBP) after neoadjuvant chemotherapy in patients with muscle-invasive transitional cell carcinoma of the bladder. * To determine compliance rates of patients with their assigned treatments. * To determine if bladder preservation is equivalent to radical cystectomy, in terms of overall survival, in responders to neoadjuvant chemotherapy. Secondary * To compare the overall survival of patients receiving SBP vs radical cystectomy. * To determine the rate of salvage cystectomy in patients undergoing bladder preservation. * To determine and compare the toxicity of treatment in both arms. * To determine and compare quality of life of patients treated with these regimens. * To compare locoregional progression-free and metastasis-free survival of patients treated with these regimens. OUTLINE: This is a multicenter study. Patients are stratified according to cancer center and randomized to 1 of 2 treatment arms. Patients are assessed after completion of 3 courses of pre-study neoadjuvant chemotherapy. Patients with poor response (≥ pT2, residual pT2, macroscopic invasive tumor) undergo immediate radical cystectomy (within 6 weeks fo completing chemotherapy). Patients\* with responsive disease (≤ pT1 tumor or macroscopically normal bladder) proceed to course 4 of chemotherapy (on-study) followed by treatment according to randomization arm. NOTE: \*Patients with a clear bladder or those who are unsure of their histological results prior to course 4 also proceed to chemotherapy. * Course 4 of neoadjuvant chemotherapy: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 and cisplatin IV over 4 hours on day 1. * Arm I (radical cystectomy): Patients undergo a radical cystectomy, including pelvic lymphadenectomy, between 4 and 6 weeks after initiating course 4 of chemotherapy. * Arm II (selective bladder preservation): Patients with no visible residual tumor (cT0 or pT0) or residual but superficial tumor (pTa, pT1) undergo radiotherapy beginning within 4-6 weeks of day 1 of course 4 and continuing for 6.5 weeks. Health-related quality of life is assessed periodically. After completion of study treatment, patients are followed periodically for up to 5 years.
