Clinical Trial Summary

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/m². 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.

Intervention

Other:
• Radiation + cisplatin
RT will encompass bilateral internal and external iliac lymph nodes at a dose of 45 Gy and the bladder up to 63 Gy. Fractionation will be 1.8 Gy per fraction. Cisplatin: 20 mg/m2/day through continuous iv perfusion for 4 consecutive days, from D2 to D5 and from D23 to D26 for the first part of the treatment, then from D2 to D5 if an additional treatment is decided. A cystoscopy with a transurethral resection will be performed 3 weeks after the last day of the first part of radio-chemotherapy. In the absence of tumor cells, the 2nd part will start on the 4th week or at latest on the 5th week after the last day of the 1st part of radio-chemotherapy. In case of a microscopic tumor residue or of a local tumor progression, operability will be re-evaluated in view of a radical cystectomy and the patient will exit the study.
• Radiation + cisplatin + gemcitabine
Radiotherapy will encompass bilateral internal and external iliac lymph nodes at a dose of 45 Gy and the bladder up to 63 Gy. Fractionation will be 1.8 Gy per fraction. Cisplatin: 20 mg/m2/day through continuous iv perfusion for 4 consecutive days, from D2 to D5 and from D23 to D26 for the first part of the treatment, then from D2 to D5 for the second part of the treatment if an additional treatment is decided. Gemcitabine: iv injection for 30 minutes, twice a week at a dose of 25 mg/m2 on days 2, 5, 9, 12, 16, 19, 23, 26, 30, and 33 for the 1st part of treatment, then on days 2, 5, 9, and 12 for the 2nd part of treatment if an additional treatment is decided (cystoscopy with a transurethral resection). RT will be delivered between 2 and 6 hours after completion of the gemcitabine injection.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Disease-free survival	The time to relapse is defined as the time from the date of randomisation to the date of the first event. Time to relapse for patients without any event (local, regional, distance, or death) will be censored at the date of latest information.	Two years after the end of the complete therapeutic sequence
Secondary	Overall survival	The time to death is defined as time from the randomization to the date of death from any cause, or to the date on which latest information is obtained.	Up to 5 years
Secondary	Acute and late toxicities	Acute and late toxicities will be scored according to the NCI-CTC v4.0.	Up to 5 years
Secondary	measurement of Quality of life	Questionnaires QLQ C30 + QLQ-BLM30 + QLQ-ELD15 + Oncodage	Up to 5 years
Secondary	Correlation between lymphocyte apoptosis and severity of late toxicities.	Before starting radiotherapy, 5ml of blood will be sampled in a 5ml heparinised tube to prospectively measure the rate of CD8 radio-induced lymphocyte apoptosis before any radiotherapy treatment. A correlation between the low rate of lymphocyte apoptosis and the severity of late toxicities will be studied to confirm the predictive power of this biological test on radio-induced side-effects.	Up to 5 years
