This is an interventional treatment trial for Distal Urethral Cancer Read More

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

• 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
