The use of plasma SELDI-TOF-MS proteomic patterns in the early detection of lung squamous cell cancers
摘要
Abstract
Objective To improve the early diagnostic rate of lung squamous cell carcinoma by using surface-enhanced desorption ionization time-of-fight mass spectrometry (SELDITOF-MS) to develop proteomic diagnosis. Methods 50 patients with lung cancer and 50 healthy individuals were detected using SELDI-TOF-MS and protein chips.The diagnostic model was established with the assistance of software and its diagnostic value was evaluated. Results There were nine peaks for the differently expressed proteins in the two groups. Three of which were highly expressed in patients with lung cancer (m/z: 9194.06, 11681.15, and 51370.19). Using tree analysis pattern, the combination of seven biomarkers (9194.06, 51370.1, 15879.1, 6624.57, 8929.80, 11681.1, and 1013.77) may identify lung cancer from normal controls with a sensitivity of 92% and a specificity of 96%.Conclusions The profiling has a high sensitivity and specificity to identify lung cancer.关键词
