RATIONALE: Diagnostic procedures using the drug EF5 to detect the presence of oxygen in tumor cells may help to plan effective treatment for solid tumors.
PURPOSE: Phase II trial to compare diagnostic procedures using EF5 to that of other methods of detecting oxygen levels in tumor cells of patients who have head and neck cancer.
|Condition or disease||Intervention/treatment||Phase|
|Head and Neck Cancer||Drug: EF5 Other: bioluminescence Other: flow cytometry Other: immunohistochemistry staining method Procedure: biopsy||Phase 2|
- Determine the distribution, degree, and intrapatient and interpatient heterogeneity of hypoxia, as measured by EF5 binding in tumor tissue, in patients with head and neck cancer.
- Determine the distribution and intrapatient and interpatient heterogeneity of CA9 expression, as measured immunohistochemically, in these patients.
- Determine the distribution, concentration, and intrapatient and interpatient heterogeneity of glucose and lactate, as measured by bioluminescence imaging, in these patients.
- Determine whether there is spatial coordination between concentrations of lactate and glucose and the location of tissue hypoxia in these patients.
- Determine whether there is spatial coordination between the location of CA9 with hypoxia and/or lactate concentrations in these patients.
OUTLINE: Patients receive EF5 IV over 1-2.5 hours on day 1. Within 24-55 hours after EF5 infusion, patients undergo surgery.
Tumor tissue samples are examined for EF5 binding by immunohistochemistry, bioluminescence imaging, and flow cytometry.
Patients are followed at 1 month and then for survival.
PROJECTED ACCRUAL: Approximately 20 patients will be accrued for this study within 1 year.
