Objectives

I.  Refine criteria for identifying the population of patients with carcinoma 
of the bladder who can be treated with radiotherapy and chemotherapy with a 
high probability of permanent tumor control.
II.  Evaluate the toxicity of combined radiotherapy and chemotherapy with 
cis-platinum both as preoperative and definitive treatment.
III.  Determine the complete regression rate for all patients on study.
IV.  Determine the degree of pathologic tumor downstaging for patients who 
achieve an incomplete regression with cis-platinum and radiotherapy and 
require cystectomy.

Entry Criteria

Disease Characteristics:

See General Eligibility Criteria

Patient Characteristics:

See General Eligibility Criteria

General Eligibility Criteria:

Patients with documented transitional 
cell carcinoma, squamous cell carcinoma, or adenocarcinoma of the bladder who 
have evaluable residual tumor in the bladder following initial TUR and who are 
suitable candidates for radical cystectomy.  Patients must have invasive 
tumors confined to the pelvis that, in the opinion of the urologist, require 
cystectomy.  Disease must be Stage B, C, or D1 (Marshall-Jewett) or T2-4, N0, 
NX, N+ (pelvis) (AJC).  Staging will be clinical, based on examination under 
anesthesia and transurethral resection.  Evidence of tumor spread beyond the 
pelvis, including lymph nodes above the aortic bifurcation, excludes.  
Patients must have a Karnofsky performance status of at least 70%, a serum 
creatinine value of less than 2.0, a 24-hour creatinine clearance of at least 
60 cc/minute, a hemoglobin of greater than 10 g, a WBC of greater than 4,000, 
and platelets greater than 100,000.  Bilirubin, alkaline phosphate, and SGOT 
must be less than twice normal.  Prior radiotherapy, chemotherapy, or surgery 
for bladder carcinoma (other than TUR) excludes.  Patients with clinically 
significant hearing deficit, prior or concurrent other malignancy except 
nonmelanomatous skin cancer, myocardial infarction within the past year, or 
medical problems that might interfere with protocol treatment or follow-up are 
ineligible.

Expected Enrollment

Approximately 74 patients will be accrued to provide 67 evaluable cases.

Outline

Nonrandomized study.  All patients are treated on Regimen A, and those who 
achieve a complete regression proceed to Regimen B.  Patients with incomplete 
regression after Regimen A enter Regimen C.
Regimen A:  Preliminary Radiotherapy plus Single-agent Chemotherapy.  
Irradiation of the bladder and regional lymphatics using effective photon 
energies of 1.25 MeV or higher; plus cis-Platinum, CACP, NSC-119875.
Regimen B:  Consolidation Radiotherapy plus Single-agent Chemotherapy.  
Irradiation of the bladder and extravesical tumor extensions; plus CACP.
Regimen C:  Surgery.  Radical cystectomy.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
