The aim of the work was to determine if, in patients with colorectal cancer, the serum metabolomic profile, erythrocyte fatty acid profile could be used to discriminate locoregional CRC from metastatic CRC, and to identify patients with liver metastases. Sera, erythrocyte membranes from 56 patients (63,2+9,4 years old) with colorectal adenocarcinoma were analyzed by GC-MS spectrometry (GC/MS system triple quad Agilent 7000B (USA). The metabolomic profiles were compared between the following groups: locoregional CRC (n = 20); liver metastases (n = 19) and extrahepatic metastases (n = 17). The control group consisted of 35 healthy people of comparable age. We found the list of metabolites capable of identifying differences between patients with liver metastases and extrahepatic metastases: serum levels of myristic acid (C14:0), linoleic acid (C18:2;n-6), phenylalanine, threonine were lower and glutamine, glucose, butanoic acid, histidine, mannose were more abundant in extrahepatic metastases in comparison with liver metastases patients (p<0,01-0,05). In erythrocyte membranes the decreased content of C12:0, С18:1;t9, C16:0/C18:2; n-6 and increased levels of C20:5;n-3, C20:4;n-6, C22:4;n-6, C22:5;n-3, (С20:3n-6 + C20:4n-6)/C18:2n-6 allowed us to distinguish extrahepatic from liver metastases (AUC 0.86, sensitivity 0.77, specificity 0.90). Significant changes in serum and erythrocyte metabolites associated with the various localization of CRC metastases were found. Created diagnostic panels should be considered promising for detecting occult metastases, selecting patients for surgical or chemotherapeutic treatment.
