The debate as to the optimal classification, staging, and treatment of gastroesophageal junction (GEJ) tumors wages on, and one must acknowledge that there is no "one-size-fits-all" approach. However, in this review we are charged with defending the position that all GEJ tumors are best treated like gastric cancer. We submit that, as stated, this is not a defensible position and that a clear definition of terms is warranted. Given the rarity of squamous cell carcinoma and the dramatic rise in incidence of adenocarcinoma of the GEJ in the West, we define GEJ "tumors" to mean adenocarcinomas of the GEJ. Furthermore, on the basis of their location, pathogenesis, and biologic behavior, we submit that few would argue with the contention that Siewert type I GEJ tumors are best treated like distal esophageal cancer and that Siewert type III GEJ tumors are best treated like gastric cancer. The real debate concerns the management of Siewert type II GEJ tumors, which arise immediately at the esophagogastric junction. Thus, for the purposes of this review, we have taken the liberty of redefining the question as what's the best way to treat adenocarcinomas of the true GEJ (i.e., Siewert type II tumors), and we submit that these tumors are in fact best treated like gastric cancer. This approach ensures that patients receive those therapies needed for the locoregional and systemic control of their disease together with a surgical procedure that optimizes complete tumor and regional lymph node resection while limiting morbidity.
关于胃食管交界(GEJ)肿瘤的最佳分类、分期及治疗的争论仍在继续,必须承认不存在“一刀切”的方法。然而,在本综述中,我们被要求捍卫这样一种立场,即所有GEJ肿瘤最好按照胃癌来治疗。我们认为,如前所述,这并非一个站得住脚的立场,有必要对术语进行明确界定。鉴于鳞状细胞癌较为罕见,且西方GEJ腺癌的发病率急剧上升,我们将GEJ“肿瘤”定义为GEJ腺癌。此外,基于其位置、发病机制及生物学行为,我们认为很少有人会反对以下观点:Siewert I型GEJ肿瘤最好按照远端食管癌来治疗,而Siewert III型GEJ肿瘤最好按照胃癌来治疗。真正的争论在于Siewert II型GEJ肿瘤的管理,这类肿瘤正好发生在食管胃交界处。因此,出于本综述的目的,我们冒昧地将问题重新定义为:治疗真正的GEJ腺癌(即Siewert II型肿瘤)的最佳方法是什么,我们认为这些肿瘤实际上最好按照胃癌来治疗。这种方法可确保患者接受疾病局部区域和全身控制所需的治疗,同时进行优化肿瘤完整切除和区域淋巴结切除且将发病率降至最低的手术。
