Abstract

Background and study aims

The timely detection of early gastric cancer (EGC) is important in performing endoscopic submucosal dissection (ESD). We attempted to determine the location characteristics of regions where EGC is frequently detected and analyzed the EGC characteristics associated with that location.

Methods

We retrospectively reviewed the medical records of patients with EGC treated by ESD between November 2008 and August 2016. We retrospectively investigated and analyzed 647 EGC lesions.

Results

The patients’ mean age was 66.7 ± 10.8 years. The patient population was predominantly male (77.1%, 499/647). A well-to-moderately differentiated carcinoma was observed in 97.2% of patients. The common site of carcinoma occurrence was the lower part of the stomach (the antrum and lower third of body, 89.6%). Among the stomach hemispheres, the lesser curvature side was the most frequent site of EGC (43.9%). The posterior side of EGC was more frequent than anterior side of EGC (20.4 vs. 15.6%, respectively). Submucosal invasive EGC was more frequent in the mid-to-upper parts of stomach than lower part of stomach (odds ratio 1.919; confidence interval 1.014–3.623; p = 0.045).

Conclusions

Most EGCs that are resectable with ESD were found in the lower part and in the lesser curvature of the stomach. The submucosal invasive EGC was more frequent in the mid-to-upper part of stomach.
