[Clinical diagnosis of adenocarcinoma of the esophago-gastric junction].
The aim of the work paper is to present the diagnosis methods of the esophago-gastric junction adenocarcinoma, based on our experience and literature data. The later reveal many novelties about diagnosis means in Barrett's esophagus (BE), the definition and classification of BE, as well as the progress of the endoscopical, immunohistochemical and molecular methods in surveillance of the dysplasia arising in BE and in detection of intraepithelial neoplasia. Early esophago-gastric junction (EGJ) adenocarcinoma (AC) is asymptomatic and its detection may be possible only through endoscopical surveillance. Although endoscopical surveillance is widely practiced, early AC represents only 20% from AC arising in BE. For this reason is necessary to use some more precise methods for identifying intestinal metaplasia on distal esophagus, in patients with gastro-esophageal reflux disease, as well as for risk stratification in patients with dysplasia and for detection of intraepithelial neoplasia. Applying modern methods of immunohistochemical and molecular diagnosis on endoscopical biopsy or esophageal brushing samples, the diagnosis rate for BE, dysplasia and early AC is improved and using the imaging means permits to obtain preoperative TNM staging and tumoral type (Siewert), with implications in therapeutical management.
