  Background: Histology-directed tissue Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry (MALDI MS) has been used to identify lipid profiles that can distinguish cancerous epithelium from normal epithelium. Methods: In order to evaluate if lipid profiles may assist with diagnosis, frozen resected tumor samples collected from papillary thyroid carcinoma patients were analyzed using Matrix (DHB/CHCA)-Assisted Laser Desorption/ Ionization (MALDI) Mass Spectrometry (MS), together with adjacent normal tissue samples. Results: Lipid peaks differentially expressed between cancer and normal samples at a feature selection P<0.001 correctly predicted class labels of test set samples (7 pairs) in 100 random training-to-test partitions, at the median class prediction accuracy of 100%. In addition, lipid peaks dif.. View More»
