Kono Y, et al. - In young patients, researchers assessed the clinicopathological features and prognosis of gastric cancer. For this investigation, they recruited patients in their 20s and 30s who were diagnosed with primary gastric cancer at four hospitals from January 2007 to January 2016. In young gastric cancer patients, a high rate of H. pylori infection was reported. As compared to patients in their 30s, those in their 20s had a worse prognosis. Examining the H. pylori infection status for young patients, as well as older patients, to identify high-risk populations should be considered.
