About
The purpose of this research study is to find out what effects, good and/or bad, dose-dense (every 14 days) chemotherapy with gemcitabine (gemcitabine hydrochloride) and cisplatin given before surgery have on patients and their muscle invasive bladder cancer.
Full description
PRIMARY OBJECTIVES:
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.
SECONDARY OBJECTIVES:
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.
TERTIARY OBJECTIVES:
I. To evaluate tissue specimens from patients to assess for molecular markers that correlate with clinical outcome.
OUTLINE:
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.

Inclusion criteria
- Patients must have histologically confirmed urothelial carcinoma of the bladder or urethra; patients with urothelial carcinoma of the prostatic urethra only may be included at primary investigator (PI) discretion; T-stage must be T2 to T4a; patients with radiographic N0 disease or N1 disease are eligible for the study; patients must not have radiographic evidence of metastatic disease; mixed histologies which are predominantly urothelial, such as with squamous or micropapillary differentiation, are allowed so long as there is no component of small cell histology; histology must be confirmed by a pathologist at an institution involved in this study
- Patients must be candidates for radical cystectomy with the goal of cure
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- Leukocytes >= 3,000/mcL
- Absolute neutrophil count >= 1,500/mcL
- Platelets >= 100,000/mcL
- Total bilirubin =< institutional upper limit of normal (ULN)
- Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT)(serum glutamic pyruvate transaminase [SGPT]) =< 2.5 X institutional ULN
- Patients must have adequate renal function defined as creatinine clearance >= 50 mL/min; for eligibility, creatinine clearance may be either calculated using the Cockcroft-Gault formula or measured with 24 hour urine collection; note that 24 hour urine collection is required at baseline, but does not have to be used for eligibility if calculated clearance by Cockcroft-Gault is preferred; nephrostomy or ureteral stent placement in order to achieve adequate creatinine clearance is allowed
- Women of child-bearing potential (WOCBP) and men with a female partner who is a WOCBP must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) starting prior to beginning treatment and continuing until at least 3 months after last dose of chemotherapy and surgery; should a woman become pregnant or suspect she is pregnant while participating in this study or if a female partner of a man participating in this study becomes pregnant, the treating physician must be notified immediately; WOCBP must have a negative serum or urine pregnancy test within 7 days prior to initiating study treatment
- No other active malignancy
- Ability to understand and the willingness to sign written informed consent and Health Insurance Portability and Accountability Act (HIPAA) documents
Exclusion criteria
- Patients who have had intravesicular therapy within 4 weeks of study entry, or those who have not recovered from adverse effects of such agents administered more than 4 weeks earlier
- Patients may not be receiving any investigational agents within 4 weeks of study entry
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to gemcitabine or cisplatin or other agents used in the study
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant women are excluded from this study
- Known human immunodeficiency virus (HIV)-positive patients on combination antiretroviral therapy are ineligible
- Patients who have undergone prior radiation to greater than or equal to 25% of the bone marrow within the past year are excluded
- Patients who have received any previous systemic chemotherapy or radiation therapy for urothelial carcinoma within 1 year of study entry are ineligible
