Prediction of Overall Survival Using Mass Spectrometry Profiling in Head and Neck Cancer Patients Treated With Epidermal Growth Factor Receptor Inhibitors
Prediction of Overall Survival Using Mass Spectrometry Profiling in Head and Neck Cancer Patients Treated With Epidermal Growth Factor Receptor Inhibitors
RATIONALE: Studying samples of blood in the laboratory from patients with cancer may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment.
PURPOSE: This research study is looking at blood sample analysis in predicting overall survival in patients with recurrent or metastatic head and neck cancer.
OBJECTIVES:
OUTLINE: Plasma and serum samples are analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and classified according to prognosis ("good" vs "poor") using a previously developed predictive algorithm.
DISEASE CHARACTERISTICS:
Diagnosis of recurrent or metastatic head and neck squamous cell carcinoma
Meets 1 of the following criteria:
Plasma and serum samples available for analysis
PATIENT CHARACTERISTICS:
PRIOR CONCURRENT THERAPY:
