Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as fluorouracil, cisplatin, and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy together with radiation therapy may kill more tumor cells.

PURPOSE: This randomized phase II trial is studying two different chemotherapy and radiation therapy regimens to see how they work in treating patients with stage II or stage III bladder cancer that was removed by surgery.

Description:

OBJECTIVES:

Primary

• To estimate the rate of distant metastasis at 3 years in patients who have undergone transurethral resection of the bladder tumor for stage II or III muscle-invasive bladder cancer treated with chemoradiotherapy comprising fluorouracil, cisplatin, and radiotherapy vs gemcitabine hydrochloride and radiotherapy followed by selective bladder preservation and adjuvant chemotherapy comprising gemcitabine hydrochloride and cisplatin.

Secondary

• To estimate the treatment completion rate in these patients.

• To estimate acute and late grade toxicities (≥ grade 3 genitourinary, gastrointestinal, and hematologic toxicities) of these regimens in these patients.

• To estimate the efficacy of these regimens, in terms of achieving complete response of the primary tumor, in these patients.

• To estimate the efficacy of these regimens, in terms of preserving the native, tumor-free bladder 5 years after completion of therapy, in these patients.

• To estimate the value of tumor histopathologic, molecular genetic, DNA content, metabolomic, and proteomic parameters as possible significant prognostic factors for initial tumor response and recurrence-free survival.

• To analyze for American Urological Association (AUA) Symptom scores at baseline and at 3 years from patients on both arms.

• To find potentially predictive biomarkers for cystectomy-free survival.

• To find potentially predictive biomarkers for acute and late toxicities.

OUTLINE: This is a multicenter study. Patients are stratified according to tumor stage (T2 vs T3-4a). Patients are randomized to 1 of 2 treatment arms.

T2a, T2b, T3a, T3b -substages? are not usually able to be determined with clinical (TURBT) staging.

2. If radiologic evaluation of a lymph node is interpreted as "positive", this must be evaluated further either by lymphadenectomy or percutaneous needle biopsy. Patients with histologically or cytologically confirmed node metastases will not be eligible.

3. Patients must have an adequately functioning bladder after thorough evaluation by an urologist and have undergone as thorough a transurethral resection of the bladder tumor as is judged safely possible.

4. Patients must be considered able to tolerate systemic chemotherapy combined with pelvic radiation therapy, and a radical cystectomy by the joint agreement of the participating Urologist, Radiation Oncologist, and Medical Oncologist.

5. History and physical examination including weight, performance status, and body surface area within 8 weeks prior to study registration

• 8.3 Platelets = 100,000 cells/mm3;

• 8.4 Hemoglobin (hgb) = 10.0 mg/dl (Note: The use of transfusion or other intervention to achieve Hgb = 10.0 g/dl is acceptable.);

9. Serum creatinine of 1.5 mg% or less; serum bilirubin of 2.0 mg% or less; creatinine clearance of 60 ml/min or greater no more than 4 weeks prior to registration; Note: Calculated creatinine clearance is permissible. If the creatinine clearance is > 60 ml/min, then a serum creatinine of up to 1.8 mg% is allowable at the discretion of the study chair;

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Patients Without Distant Metastases by Three Years	Distant metastasis occurrence is defined as the first appearance of disease (with radiographic evidence) in a non-regional lymph node, solid organ or bone.	From randomization to three years
Secondary	Percentage of Patients Who Completed Treatment Per Protocol	Treatment administration data was centrally reviewed to determine if patients completed each treatment component per protocol.	After each treatment component (induction, consolidation, adjuvant). Timing varies bases on arm, tumor response at multiple time points, and allowed time ranges.
Secondary	Percentage of Patients With Grade 3 or Higher Genitourinary, Gastrointestinal, or Hematologic Adverse Events	Highest grade adverse event (AE) per subject was counted. Adverse events were graded using the Common Terminology Criteria for Adverse Events (CTCAE) v3.0. Grade refers to the severity of the AE. The CTCAE v3.0 assigns Grades 1 through 5 with unique clinical descriptions of severity for each AE based on this general guideline: Grade 1 Mild, Grade 2 Moderate, Grade 3 Severe, Grade 4 Life-threatening or disabling, Grade 5 Death related to AE. All adverse events are counted, regardless of reported relationship to protocol treatment.	From start of treatment to 180 days after the end of treatment. Treatment could last up to 40 weeks depending on arm, tumor response, and allowed time ranges.
Secondary	Number of Patients Experiencing Complete Response of the Primary Tumor After Induction Therapy	Patients will be considered as having a clinical complete response when all biopsies are negative at the site(s) of the pretreatment tumor(s).	3-4 weeks following induction therapy (approximately maximum 8 weeks from start of treatment depending on treatment arm and allowed time windows)
Secondary	Number of Participants With Progression or Removal of Bladder Five Years After Therapy	Progression is defined as an increase of 50% or more in the largest diameter of the endoscopically appreciable tumor in the tumor-site biopsy specimen, the development of new bladder tumors, or the development of metastatic disease.	From start of treatment to five years after the end of therapy. Treatment could last up to 40 weeks depending on arm, tumor response, and allowed time ranges.
Secondary	Change in American Urological Association Symptom Index (AUASI) Score at 3 Years	The AUASI is a validated 7-item measure used to assess urinary symptoms. A higher score indicates more severe symptoms for the individual questions and overall total. Six questions ask about frequency of symptoms over the past month with possible responses: 0= Not at all; 1 = Less than 1 time in 5; 2 = less than half the time, 3 = About half the time, 4 = More than half the time, 5 = Almost always. An additional question asks the number of times one gets up to urinate after going to bed, with response indicating the exact number of times ranging from 0 to 5. The total score is the sum of the questions and ranges from 0 to 35. Change is calculated as 3-year score - baseline score such that a negative change indicates improvement.	Baseline and 3 years
Secondary	Determining Potentially Predictive Biomarkers for Acute and Late Toxicities		The protocol did not provide sufficient detail to meet National Cancer Institute requirements for release of specimens from the NRG tissue bank for the protocol-specified analysis, therefore no assays were performed and no data were collected for this out
Secondary	Determining Potentially Predictive Biomarkers for Cystectomy-free Survival		The protocol did not provide sufficient detail to meet National Cancer Institute requirements for release of specimens from the NRG tissue bank for the protocol-specified analysis, therefore no assays were performed and no data were collected for this out
