Esophageal cancer (EC) is one of the most aggressive malignant tumors of the gastrointestinal tract. It is well known that cancer initiation and tumor development are closely linked with inflammation. C-reactive protein (CRP) and interleukin-6 (IL-6) are acute-phase proteins involved in cancer development. It was suggested that CRP and IL-6 play potential roles in the growth and progression of malignant tumors, including EC. The aim of the study was to describe the significance of IL-6 and CRP in the development of esophageal cancer and to assess the potential role of their serum levels as prognostic indicators of EC patient's survival.
