If radical cystectomy remains the standard of care for muscle invasive bladder cancer, consequences of this surgical procedure are often harsh. Over the past years, concurrent chemo-radiotherapy has imposed itself as an alternative treatment. Published data on concomitant radiochemotherapy (radiotherapy/cisplatin or radiotherapy/cisplatin/5-fluorouracil combinations) showed local control rates with bladder preservation at 5 years ranging from 40% to 65% according to the disease stage, and overall survival probabilities ranging from 40% to 50% at 5 years. In order to improve local and systemic prognosis, evaluation of other chemotherapy agents with higher radiosensitizing effect, such as gemcitabine, is justified. Gemcitabine possesses its own anti-cancer activities on urothelial diseases and has a synergetic activity with cisplatin. The investigators completed a monocenter phase I study combining radiotherapy, cisplatin, and twice-weekly gemcitabine, and determined a recommended dose of gemcitabine 25 mg/m. The objective of the present study is to evaluate the combination of radiotherapy + cisplatin + gemcitabine in terms of disease-free survival in non metastatic muscle invasive urothelial cancer patients.

Yes No Not Sure

Inclusion Criteria

No distant metastases (Thorax, abdomen, and pelvic CT-scan, bone scan)
Efficient contraception for premenopausal women, maintained during the whole treatment and up to two months after the completion of radiotherapy
No radiotherapy or chemotherapy history except for in situ bladder lesions
No carcinological history except for non melanoma skin tumours, in situ uterine cervix cancer
No contraindication to gemcitabine or cisplatin
No contraindication to radiotherapy
