Summary: | Purpose: New and more consistent biomarkers of head and neck squamous cell carcinoma (HNSCC) are needed to improve early detection
of disease and to monitor successful patient management. The purpose of this study was to determine whether a new proteomic
technology could correctly identify protein expression profiles for cancer in patient serum samples.
Experimental Design: Surface-enhanced laser desorption/ionization-time of flight-mass spectrometry ProteinChip system was used to screen for differentially
expressed proteins in serum from 99 patients with HNSCC and 102 normal controls. Protein peak clustering and classification
analyses of the surface-enhanced laser desorption/ionization spectral data were performed using the Biomarker Wizard and Biomarker
Patterns software (version 3.0), respectively (Ciphergen Biosystems, Fremont, CA).
Results: Several proteins, with masses ranging from 2,778 to 20,800 Da, were differentially expressed between HNSCC and the healthy
controls. The serum protein expression profiles were used to develop and train a classification and regression tree algorithm,
which reliably achieved a sensitivity of 83.3% and a specificity of 100% in discriminating HNSCC from normal controls.
Conclusions: We propose that this technique has potential for the development of a screening test for the detection of HNSCC. |
