|Distal Urethral Cancer Proximal Urethral Cancer Squamous Cell Carcinoma of the Bladder Stage II Bladder Cancer Stage III Bladder Cancer Urethral Cancer Associated With Invasive Bladder Cancer||Drug: gemcitabine hydrochloride Drug: cisplatin Procedure: therapeutic conventional surgery Other: laboratory biomarker analysis||Phase 2|
|Study Design:||Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Treatment
|Official Title:||Phase II Trial of Neoadjuvant Dose Dense Gemcitabine and Cisplatin In Muscle Invasive Bladder Cancer|
- Pathological Complete Response Rate Following Chemotherapy Before Surgery [ Time Frame: Up to 5 years ]Pathological response rate following neoadjuvant chemotherapy was assessed by TNM staging at the time of radical cystectomy
|Study Start Date:||May 2012|
|Estimated Study Completion Date:||December 2018|
|Primary Completion Date:||December 2013 (Final data collection date for primary outcome measure)|
Experimental: Treatment (gemcitabine hydrochloride, cisplatin, surgery)
Patients receive gemcitabine hydrochloride IV over 30 minutes on day 1 and cisplatin IV on day 1 or divided over days 1 and 2. Treatment repeats every 14 days for 3 courses in the absence of disease progression or unacceptable toxicity. Beginning 3-8 weeks after chemotherapy, patients undergo radical cystectomy.
Drug: gemcitabine hydrochloride

I. To assess the rate of complete response (pT0) at cystectomy following preoperative dose dense gemcitabine and cisplatin (DD GC) in patients with muscle invasive urothelial carcinoma of the bladder.
I. To assess the toxicity profile of DD GC when given in the neoadjuvant setting: To define the number of patients who complete all three cycles of treatment without dose reduction, and to describe the incidence of toxicity.
II. To assess the 5 year overall and relapse free survival in patients who receive neoadjuvant DD GC.
I. To evaluate tissue specimens from patients to assess for molecular markers that correlate with clinical outcome.
Patients receive gemcitabine hydrochloride intravenously (IV) over 30 minutes on day 1 and cisplatin IV on day 1 or divided over days 1 and 2. Treatment repeats every 14 days for 3 courses in the absence of disease progression or unacceptable toxicity. Beginning 3-8 weeks after chemotherapy, patients undergo radical cystectomy.
After completion of study treatment, patients are followed up for 5 years.
