| Core Tip |
Chronic helicobacter pylori (H. pylori) infection is a major risk factor for gastric cancer. Historically, gastric cancers in Japan were related to H. pylori infection, and the frequency of H. pylori uninfected gastric cancer (HpUIGC) was very rare. However, the rarity of gastric cancer in H. pylori negative patients may be partly owing to underreporting, and the mechanisms behind the development and progression of this type of gastric cancer must be elucidated. This study elucidated the clinicopathological features of H. pylori uninfected gastric cancer from 30 gastric cancer patients. Differentiated-type gastric cancers without submucosal invasion were most prominent. |
