To determine whether proteomic profiling with surface-enhanced laser desorption/ionization time of flight mass spectrometry can identify serum protein signatures for head and neck squamous cell carcinoma and detect known tumor markers.
Screened serum samples using the SELDI-TOF ProteinChip system across 99 patients with head and neck squamous cell carcinoma (HNSCC), 25 healthy smokers, and 102 healthy normal controls.
Conducted protein peak clustering and classification tree analysis on spectral data, and provisionally validated a candidate peak via SELDI immunoassay and radioimmunoassay.
Developed a classification tree algorithm from differentially expressed proteins (ranging from 2,778 to 20,800 Da) that achieved a sensitivity of 83.3%, specificity of 90%, positive predictive value of 80%, and negative predictive value of 92% in distinguishing HNSCC from controls.
Identified a 10,068-Da differential protein peak in HNSCC patient sera corresponding to metallopanstimulin-1 (MPS-1), which correlated consistently with MPS-1 levels measured by radioimmunoassay.
