The NCCN Clinical Practice Guidelines in Oncology for Gastric Cancer provide evidence- and consensus-based recommendations for a multidisciplinary approach for the management of patients with gastric cancer. For patients with resectable locoregional cancer, the guidelines recommend gastrectomy with a D1+ or a modified D2 lymph node dissection (performed by experienced surgeons in high-volume centers). Postoperative chemoradiation is the preferred option after complete gastric resection for patients with T3-T4 tumors and node-positive T1-T2 tumors. Postoperative chemotherapy is included as an option after a modified D2 lymph node dissection for this group of patients. Trastuzumab with chemotherapy is recommended as first-line therapy for patients with HER2-positive advanced or metastatic cancer, confirmed by immunohistochemistry and, if needed, by fluorescence in situ hybridization for IHC 2+.

Esophageal cancer is the sixth most common cause of cancer deaths worldwide. Adenocarcinoma is more common in North America and Western European countries, originating mostly in the lower third of the esophagus, which often involves the esophagogastric junction (EGJ). Recent randomized trials have shown that the addition of preoperative chemoradiation or perioperative chemotherapy to surgery significantly improves survival in patients with resectable cancer. Targeted therapies with trastuzumab and ramucirumab have produced encouraging results in the treatment of advanced or metastatic EGJ adenocarcinomas. Multidisciplinary team management is essential for patients with esophageal and EGJ cancers. This portion of the NCCN Guidelines for Esophageal and EGJ Cancers discusses management of locally advanced adenocarcinoma of the esophagus and EGJ.
