ASGE Postgraduate Course at ACG: Evidence-based Updates for the Practicing Gastroenterologist (On-Demand) | October 2021 OLPGATACG21-Gastric Cancer: Who and How to Screen

Video Transcription

Video Summary

The video features Sawani Namgang Ruafang, an assistant professor of medicine at Johns Hopkins, speaking about gastric cancer screening. Gastric cancer is one of the most common cancers and the third leading cause of cancer death worldwide. While the overall incidence of gastric cancer is low in the United States, there are significant variations in incidence across different ethnicities. Asian subgroups such as Japanese Americans and Korean Americans have a high risk of gastric cancer. The risk of gastric cancer is still high for first-generation immigrants from high-incidence countries, but it decreases in succeeding generations. Gastric intestinal metaplasia (IM) and atrophic gastritis are precursor lesions for gastric cancer, driven by factors such as H. pylori infection. Screening methods include using narrowband imaging (NBI) and mapping biopsy to improve detection of gastric IM. If dysplastic lesions or early gastric cancer are identified, the recommended treatment options are endoscopic resections, such as endoscopic submucosal dissection (ESD), or surgery. It is important to evaluate the risk of developing gastric cancer and customize screening methods accordingly.
