Surgical resection remains the mainstay of treatment for localized gastric adenocarcinoma. The type and extent of resection depends on tumor location. Although the incidence of gastric cancer has been declining, a shift has occurred to more tumors involving the proximal compared with the distal stomach. Appropriate treatment depends on a thorough staging process to exclude the presence of distant metastatic disease. Current staging modalities include high-quality CT scan, endoscopic ultrasound, PET, and laparoscopy. The value of peritoneal lavage to detect occult peritoneal disease is under investigation. The principles of surgical resection have always included negative resection margins and adequate lymph node examination. Controversial topics requiring further study include laparoscopic resections and hepatic metastasectomy. This review highlights the salient points of current surgical management of gastric adenocarcinoma.

Gastric cancer is the fifth most frequently diagnosed cancer and the third leading cause of death from cancer in the world. Several advances have been made in the staging procedures, imaging techniques, and treatment approaches. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Gastric Cancer provide an evidence- and consensus-based treatment approach for the management of patients with gastric cancer. This manuscript discusses the recommendations outlined in the NCCN Guidelines for staging, assessment of HER2 overexpression, systemic therapy for locally advanced or metastatic disease, and best supportive care for the prevention and management of symptoms due to advanced disease.

Esophageal cancer is the sixth leading cause of cancer-related deaths worldwide. Squamous cell carcinoma is the most common histology in Eastern Europe and Asia, and adenocarcinoma is most common in North America and Western Europe. Surgery is a major component of treatment of locally advanced resectable esophageal and esophagogastric junction (EGJ) cancer, and randomized trials have shown that the addition of preoperative chemoradiation or perioperative chemotherapy to surgery significantly improves survival. Targeted therapies including trastuzumab, ramucirumab, and pembrolizumab have produced encouraging results in the treatment of patients with advanced or metastatic disease. Multidisciplinary team management is essential for all patients with esophageal and EGJ cancers. This selection from the NCCN Guidelines for Esophageal and Esophagogastric Junction Cancers focuses on recommendations for the management of locally advanced and metastatic adenocarcinoma of the esophagus and EGJ.
