Popis: | Circulating tumor cells (CTCs) have been shown to be heterogeneous. Focusing on the epithelial–mesenchymal transition and perioperative kinetics, we evaluated CTCs with mesenchymal phenotypes as a potential prognostic biomarker for patients with gastric cancer. Peripheral blood was collected from 54 patients with gastric cancer before surgery and at 1 week and 1 month after surgery. CTCs were enriched using density-gradient centrifugation and magnetic-activated cell sorting (negative selection). Cell suspensions were characterized by multi-immunofluorescence staining against cytokeratin and N-cadherin, and by 4′,6′-diamidino-2-phenyldole staining. CTCs were detected in five patients (17%) with early cancer and 14 patients (56%) with advanced cancer (p |
