简要总结
RATIONALE: Drugs used in chemotherapy, such as fluorouracil, cisplatin, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy together with radiation therapy may kill more tumor cells.
PURPOSE: This randomized phase II trial is studying two different chemotherapy and radiation therapy regimens to see how they work in treating patients with stage II or stage III bladder cancer that was removed by surgery.
详细描述
OBJECTIVES:
Primary
- To estimate the rate of distant metastasis at 3 years in patients who have undergone transurethral resection of the bladder tumor for stage II or III muscle-invasive bladder cancer treated with chemoradiotherapy comprising fluorouracil, cisplatin, and radiotherapy vs gemcitabine hydrochloride and radiotherapy followed by selective bladder preservation and adjuvant chemotherapy comprising gemcitabine hydrochloride and cisplatin.
Secondary
- To estimate the treatment completion rate in these patients.
- To estimate acute and late grade toxicities (≥ grade 3 genitourinary, gastrointestinal, and hematologic toxicities) of these regimens in these patients.
- To estimate the efficacy of these regimens, in terms of achieving complete response of the primary tumor, in these patients.
- To estimate the efficacy of these regimens, in terms of preserving the native, tumor-free bladder 5 years after completion of therapy, in these patients.
- To estimate the value of tumor histopathologic, molecular genetic, DNA content, metabolomic, and proteomic parameters as possible significant prognostic factors for initial tumor response and recurrence-free survival.
- To analyze for American Urological Association (AUA) Symptom scores at baseline and at 3 years from patients on both arms.
- To find potentially predictive biomarkers for cystectomy-free survival.
- To find potentially predictive biomarkers for acute and late toxicities.
