食管胃交界处腺癌的临床研究进展

Clinical research progress in adenocarcinoma of the esophagogastric junction

食管胃交界处腺癌(adenocarcinoma of esophagogastric junction,EGJA)有其独特的解剖学位置,同时又位于鳞状上皮与柱状上皮交界之处,其生物学特性不同于食管癌和胃癌,诊断分型一直存在众多的争议,治疗模式在学术界也始终没有公认的"金标准",特别是局部进展期EGJA的治疗策略更是难以抉择。随着影像学技术的发展和各项大型临床研究结果的公布,EGJA的治疗日益个体化,同时也凸显了多学科协作的重要性。本文将针对以上问题对EGJA的最近进展做一综述。

The adenocarcinoma of the esophagogastric junction （EGJA） is located in a unique anatomical position and at the junction of the squamous epithelium and the columnar epithelium. The biological characteristics of this disease are different from those of esophageal or gastric cancer. The diagnostic classification of EGJA has been subject to controversies, and no gold standard therapeu-tic regimens have been established, especially in the choice of treatment of locally advanced EGJA. Results from large-scale clinical tri-als and imaging technology development showed that the treatment of EGJA has been individualized. Furthermore, this problem high-lights the importance of multidisciplinary collaboration. This article focuses on current progress in studies on EGJA.
