%0 Journal Article %T Cytokines Association with Clinical and Pathological Changes in Esophageal Squamous Cell Carcinoma %A Dorota Diakowska %J Disease Markers %D 2013 %R 10.1155/2013/302862 %X Carcinogenic transformation of cells in esophageal squamous cell carcinoma (ESCC) is characterized on molecular level by, among other things, changes in protein expression. Among all proteins related to inflammation, cytokines may be implicated as possible biological markers of esophageal cancer. These biomarkers, near imaging techniques, may be helpful in diagnosis and monitoring therapy in ESCC patients. This review demonstrates findings of researches on dysregulation of cytokines in ESCC and their clinical and pathological implications. Articles on cytokines were selected according to the following criteria: (i) the study was performed at protein level, (ii) the differences in cytokines expression or concentration were detected in tissues or serum from ESCC patients, (iii) the alterations of cytokines levels were detected by: immunohistochemistry (IHC), western blot (WB) and enzyme-linked immunosorbent assay (ELISA). Members of VEGF family seem to play an essential role as potential markers in ESCC. The results of all cytokines researches are promising but further studies are necessary to establish the biological significance of these peptydes in ESCC, their potential usefulness for early diagnosis, pre- and postoperative prognosis and monitoring of the respond to chemo- and radiotherapy of cancer patients. 1. Introduction Cancers of esophagus are placed among the most common malignancies worldwide, being the eighth leading cause of cancer-related deaths [1]. Esophageal squamous cell carcinoma (ESCC) is a dominant histological type of esophageal malignances [1, 2]. This cancer is usually detected in the advanced stage of disease, when regional and/or distant metastases are presented [2, 3]. For this reason, poor prognosis and survival prediction for ESCC patients are observed. In ESCC, dissemination of disease at diagnosis is favored by lack of serosa and rich structure of submucosal lymphatic vessels [1¨C3]. Because of that most ESCC patients have invisible micrometastases in tumor region at the time of diagnosis. Surgical resection of tumor is an essential method of ESCC treatment. Then, radio- and chemotherapy are complementary methods of treatment [4, 5]. Development of clinical observations related to such imaging techniques as endoscopy, computer tomography (CT), magnetic resonance, and positron emission tomography, helps in detection of dysplasia or neoplasia in the esophagus. These techniques are usually very accurate in the determination of methods of cancer treatment. However, it is occasionally demonstrated in the time of operation, that %U http://www.hindawi.com/journals/dm/2013/302862/
