Bladder Cancer

Radiation Therapy + Chemotherapy for Stage T1 Bladder Cancer (UW 7684/RTOG 0926)
RTOG 0926 A Phase II Protocol For Patients With Stage T1 Bladder Cancer to Evaluate Selective Bladder Preserving Treatment By Radiation Therapy Concurrent With Radiosensitizing Chemotherapy Following a Thorough Transurethral Surgical Re-Staging.
Status Conditions Phase Study ID
Recruiting Bladder Cancer Phase II UW 7684

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Drugs used in chemotherapy, such as cisplatin, mitomycin C, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving radiation therapy together with cisplatin may kill more tumor cells.

PURPOSE: This phase II trial is studying how well radiation therapy given together with chemotherapy works in treating patients with stage I bladder cancer.

Eligibility Criteria (must meet the following to participate in this study)
  • Carcinoma of the bladder pathologically (histologically or cytologically) diagnosed within the past 10 weeks, meeting either of the following criteria:
    • Patients with operable tumors that are primary transitional cell carcinoma of the bladder exhibiting histologic evidence of invasion into the lamina propria (disease clinical stage T1) without evidence of muscularis propria invasion (muscularis propria must be present in the transurethral resection of the bladder tumor [TURBT] specimen) and are AJCC clinical stage T1, NX or N0, M0 without hydronephrosis
    • Patients with disease involvement of the prostatic urethra with transitional cell carcinoma and have no evidence of stromal invasion of the prostate
  • No pN+ or > T1 disease
  • No histologically or cytologically confirmed node metastases
    • If radiologic evaluation of a lymph node is interpreted as "positive", this must be evaluated further either by lymphadenectomy or by percutaneous needle biopsy
  • No evidence of distant metastases
  • Must have a T1G2 or T1G3 transitional cell carcinoma that has recurred within 18 months after initial treatment for ≤ T1 tumors (TURBT and intravesical BCG immunotherapy) or have presented to a participating urologist who judged BCG therapy is contraindicated because patient may be immunocompromised
  • Patients for whom radical cystectomy is the standard next therapy per urologic guidelines, in the judgment of the participating urologist, are eligible
  • Must have an adequately functioning bladder as judged by the participating urologist and radiation oncologist and have undergone a visibly complete re-staging TURBT by the participating urologist that shows (or is present on the outside pathology specimen) a T1G2 or T1G3 tumor with uninvolved muscularis propria in the specimen and, if on prostatic urethral biopsy mucosal carcinoma is present, there is no evidence on biopsy in the prostatic stroma of tumor invasion


  • Zubrod performance status 0-1
  • WBC ≥ 4,000/mm^3
  • ANC ≥ 1,800/mm^3
  • Platelet count ≥ 100,000/mm^3
  • Hemoglobin ≥ 10.0 g/dL (transfusion or other intervention allowed)
  • Serum creatinine ≤ 1.5 mg/dL

  • Glomerular filtration rate (GFR) > 25 mL/min (for patients receiving cisplatin, GFR > 60 mL/min)
  • Not pregnant
  • Negative pregnancy test
  • Fertile patients must use effective contraception
  • Able to tolerate systemic chemotherapy combined with radiotherapy and a radical cystectomy (if necessary), in the opinions of the urologist, radiation oncologist, and medical oncologist
  • No prior or concurrent malignancy of any other site or histology (except for nonmelanomatous skin cancer, T1a prostate cancer, or carcinoma in situ of the uterine cervix) unless the patient has been disease-free for ≥ 5 years
  • No severe, active co-morbidity including any of the following:
    • Unstable angina and/or congestive heart failure that required hospitalization within the past 6 months
    • Transmural myocardial infarction that occurred within the past 6 months
    • Acute bacterial or fungal infection requiring IV antibiotics at the time of registration
    • Chronic obstructive pulmonary disease exacerbation or other respiratory illness requiring hospitalization or precluding any study therapy at the time of registration
    • Hepatic insufficiency resulting in clinical jaundice and/or coagulation defects
    • AIDS based upon the current Centers for Disease Control definition (HIV testing not required)
  • No prior allergic reaction to cisplatin, mitomycin, or fluorouracil


  • No prior systemic chemotherapy for bladder cancer
  • Prior chemotherapy for a different cancer allowed
  • No prior radiotherapy to the region of this cancer that would result in overlap of radiotherapy fields
  • No concurrent drugs that have potential nephrotoxicity or ototoxicity (e.g., aminoglycoside)
