This study serves, in part, to prepare for a future large cohort study. The goal of the study is: 1. The collection of various tissue samples (blood, biopsies and "esophageal brushes") and their analysis. 2. To set up standardized methods for different genetic analyses (DNA-FISH and so-called single cell sequencing) on the esophageal tissue samples. 3. Evaluating the quality of life of Barrett's Esophagus patients and the degree of fear of getting cancer. Patients with a Barrett's Esophagus can participate in the study if they are minimally 18 years old, are capable of giving informed consent (fully understanding what the study entails before giving consent to participate), have Barrett Esophagus and are referred to one of the participating centers due to suspicion of high-grade dysplasia or early esophageal cancer, for which the participant will be evaluated by endoscopic imaging and biopsy. Study procedures: * An intake consultation will be planned, wherein the eligibility criteria will be assessed, and participant characteristics will be collected. * A routine gastroscopy will be planned twice during which several minimally-invasive interventions will be performed: drawing a blood sample, brush cytology during the endoscopy (a brush is used to obtain cells from the surface of the esophagus) and obtaining biopsy samples (small pieces of tissue). Each participant will need to undergo all the interventions. * Patients will have to complete questionnaires at three time points to assess their quality of life (EQ-5D-DL questionnaire) and fear of cancer recurrence (Cancer Worry Scale).

More specifically, you will have a standard endoscopy twice during which tissue samples will be taken from the esophagus to check for the severity of the disease. This is part of standard care. If you participate in the study, additional samples will be taken from the esophagus and also from the stomach (a total maximum of 10 samples of 1-2 mm). As a result, the endoscopic examination will take about 10-15 minutes longer than standard. Furthermore, in addition to the tissue samples, cells of the esophageal mucosa will be sampled (through 4 "esophageal brushes") and blood (4 tubes) will also be collected. For this study, you will be contacted a total of three times. Once for a screening visit and twice for the sample collection described above. The screening and sample collection will take place during the already scheduled treatments and consultations. Afterwards, patient outcomes will be documented for the study until a maximum of 5 years after inclusion. This documentation will take place during the routine follow up so does not require any additional visits for the patients. Additionally you will be asked to complete two short questionnaires on your mobile phone at three time points during the study.
