Research on Serum Spectrum Analysis Model Applied to Pathema Identification

Article Preview

Abstract:

The SELDI-TOF MS serum peptide profiles of normal and malignant tumor samples were studied by pattern recognition method. In this study, Partial Least Squares-Discriminate Analysis (PLS-DA) combined with consensus classification model was constructed to predict practical serum samples and compared with the results of principal component analysis (PCA) method. The correctness of consensus PLS-DA classification model for normal and malignant samples was 90% and 84% respectively. So the approach proposed was proved to be a reliable and practicable method for cancer identification.
