Introduction: Esophageal cancer ranks eighth among the most common malignancies worldwide. The two most common types are adenocarcinoma and spinocellular carcinoma. Correct histopathological diagnosis, cancer staging and identification of predictive risk factors of progression are important in terms of further disease course and management. While patients with mucosal carcinoma without risk factors are treated endoscopically, those with submucosal invasion or mucosal carcinoma with risk factors are referred for surgical therapy according to current recommendations. Histopathology is still considered the gold standard in diagnosis, often used in conjunction with immunohistochemistry, e.g., to document a TP53 gene mutation, which plays an important role in the pathogenesis and progression of esophageal dysplasia. New diagnostic methods, such as confocal laser endomicroscopy (CLE), also play an important role. Other crucial factors include patient follow-up, early and reliable detection of persistent or recurrent lesions. Aims, methods and patients: In the thesis, 4 separate, partly connected projects are assessed together, with a partial overlap of patients. The aims of the individual projects were as follows: 1) To identify predictive factors of esophageal cancer progression, risk of metastasis and...
