        History of Esophagogastric Junction Cancer Treatment and Current Surgical Management in Western Countries

        Felix Berlth,Arnulf Heinrich Hoelscher 대한위암학회 2019 Journal of gastric cancer Vol.19 No.2

        The incidence of esophagogastric junction (EGJ) cancer has been significantly increasing in Western countries. Appropriate planning for surgical therapy requires a reliable classification of EGJ cancers with respect to their exact location. Clinically, the most accepted classification of EGJ cancers is “adenocarcinoma of the EGJ” (AEG or “Siewert”), which divides tumor center localization into AEG type I (distal esophagus), AEG type II (“true junction”), and AEG type III (subcardial stomach). Treatment strategies in western countries routinely employ perioperative chemotherapy or neoadjuvant chemoradiation for cases of locally advanced cancers. The standard surgical treatment strategies are esophagectomy for AEG type I and gastrectomy for AEG type III cancers. For “true junctional cancers,” i.e., AEG type II, whether the extension of resection in the oral or aboral direction represents the most effective surgical therapy remains debatable. This article reviews the history of surgical EGJ cancer treatment and current surgical strategies from a Western perspective.

        Multimodal Treatment Strategies in Esophagogastric Junction Cancer: a Western Perspective

        Goetze, Thorsten Oliver,Al-Batran, Salah-Eddin,Berlth, Felix,Hoelscher, Arnulf Heinrich The Korean Gastric Cancer Association 2019 Journal of gastric cancer Vol.19 No.2

        Esophagogastric junction (EGJ) cancer is a solid tumor entity with rapidly increasing incidence in the Western countries. Given the high proportion of advanced cancers in the West, treatment strategies routinely employed include surgery and chemotherapy perioperatively, and chemoradiation in neoadjuvant settings. Neoadjuvant chemoradiation and perioperative chemotherapy are mostly performed in esophageal cancer that extends to the EGJ and gastric as well as EGJ cancers, respectively. Recent trials have tried to combine both strategies in a perioperative context, which might have beneficial outcomes, especially in patients with EGJ cancer. However, it is difficult to recruit patients for trials, exclusively for EGJ cancers; therefore, the results have to be carefully reviewed before establishing a standard protocol. Trastuzumab was the first drug for targeted therapy that was positively evaluated for this tumor entity, and there are several ongoing trials investigating more targeted drugs in order to customize effective therapies based on tissue characteristics. The current study reviews the multimodal treatment concept for EGJ cancers in the West and summarizes the latest reports.
