Abstract As lipids area associated with functions such as chemical-energy storage, cellular signaling, cell membranes, and cell to cell interaction, they play a key role in cellular survival, proliferation, and death. These cellular processes are vitally concerned with carcinogenesis pathways, especially to transformation, progression, and metastasis, suggesting the bioactive lipids are mediators of a number of oncogenic processes. According to recent lipidomics research, lipid analysis regarding canceris very important, since each type of cancer has different carcinogenesis pathways. In this study, lipids from plasma of healthy controls and patients with cancers (liver, stomach, lung, colorectal, and thyroid) were investigated in order to discover lipids that show significant difference between the groups and find potential lipid biomarkers for each cancer. Blood plasma were extracted from each control and cancer patients using the modified Folch method with MTBE/methanol, and the extracted lipids were analyzed by nLC-ESI-MS/MS. A total of 243, 236, 239, 239, 239, and 225 lipids from plasma of patients with liver, stomach, lung, colorectal, thyroid cancer, and controls, respectively, were identified and profiling of lipid from each case of cancer was compared with that of controls.
