Brief Summary:
This pilot research trial studies how well myeloid derived suppressor cells (MDSC) clinical assay works in finding and monitoring cancer cells in blood and urine samples from patients with or without localized or metastatic bladder cancer. Studying samples of blood and urine from patients with or without bladder cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer and may help doctors improve ways to diagnose and treat patients.

Detailed Description:

PRIMARY OBJECTIVES:

I. To evaluate a novel clinical assay (MDSC clinical assay) to detect cancer associated immune cells in the peripheral blood of patients as a means to better detect and monitor malignant bladder cancer in patients.

II. Estimate mean MDSC level, intra-patient variability, and inter-patient variability, for 3 groups of subjects with variable bladder cancer disease status at baseline.

III. In patients with known localized, muscle-invasive bladder cancer who undergo surgical treatment: to determine the change in MDSC level from baseline to after treatment including surgery.

IV. In patients with known metastatic bladder cancer who undergo systemic treatment: to determine the change in MDSC level from baseline to after 4 cycles of treatment compared to the change in tumor burden as evaluated by radiographic imaging.

V. In patients with no history of cancer: to determine the changes in MDSC levels from baseline to after 4 months.

SECONDARY OBJECTIVES:

I. Compare MDSC level measurements to urine cytology analysis at baseline and after treatment to determine whether the two tests correlate in any of the 3 groups of patients defined in this study.

OUTLINE:

GROUP I: Patients without cancer undergo collection of blood and urine samples for analysis via MDSC clinical assay at baseline, 1 week, and 4 months.

GROUP II: Patients with localized bladder cancer undergo collection of blood and urine samples for analysis via MDSC clinical assay at baseline, 1 week, and within 4 weeks after cystectomy.

GROUP III: Patients with metastatic cancer undergo collection of blood and urine samples for analysis via MDSC clinical assay at baseline, 1 week, and within 4 weeks after completion of 4 courses of systemic chemotherapy.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change in MDSC level in patients with known localized, muscle-invasive bladder cancer who undergo surgical treatment [ Time Frame: Baseline to up to 4 months ]
  2. Change in MDSC level in patients with known metastatic bladder cancer who undergo systemic treatment [ Time Frame: Baseline to up to 6 months ]
    The direction and magnitude of the changes in Group 3 will be compared to the changes in tumor burden assessed radiographically - to explore the associations.

  3. Change in MDSC level in patients with no history of cancer [ Time Frame: Baseline to 4 months ]
  4. Change in tumor burden evaluated by radiographic imaging [ Time Frame: Baseline to up to 1 year ]

Secondary Outcome Measures :
  1. Change in urine cytology analysis [ Time Frame: Baseline to up to 4 months ]
    The MDSC levels at baseline will be compared (plots and correlations) to the urine cytology levels (Groups 2 and 3) to describe any associations; for Group 3, the changes (baseline to post treatment) in the MDSC levels will be compared to the changes in urine cytology.

Criteria

Inclusion Criteria:

  • Subjects must meet the criteria for one of the three following groups:

    • Normal patients- aged 40 years and older with no evidence of hematuria or cancer
    • Patients with localized bladder cancer diagnosed by cystoscopy and pathology: T2N0M0 or T3N0M0 who have not received neoadjuvant chemotherapy
