Endoscopic Ultrasound in Gastric Cancer

Abstract

Gastric cancer remains one of the most common causes of cancer death worldwide. Endoscopic ultrasound (EUS) plays a key role in the diagnosis and staging of gastric cancer. EUS can allow for in-depth cancer staging by detailing tumor size, depth of invasion in the gastric wall, presence of metastatic lymphadenopathy, and detection of liver metastases. EUS can also help distinguish among a variety of subepithelial gastric mass lesions, many of which are neoplastic. These factors help guide decision management in terms of appropriateness for endoscopic or surgical resection and overall management strategy for patients.
