Abstract: To evaluate the diagnostic yield of early gastric cancer in Thai Nguyen

Materials and Method: A descriptive study on 26 patients who underwent  Early detection of gastric cancer by endoscpy procedure.

Results:The rate of man was 69,2% while that of women was 20,8%. Most of the patients ( 96,1%) were in high risk of gastrics cancar as chronic gastritis, high-risk background mucosa. We should be aware of the indicators of a suspicious lesion like:  a well-demarcated lesion 69,2%,  irregularity in color/surface pattern 84,6%; vessel plus surface classification using magnifying endoscopy with narrow-band imaging findings of  irregular microvascular pattern with a demarcation line or  irregular microsurface pattern. Most of of the lesions located on the antrum (57,7%) and was under 2cm in size (84,6%).

Conclusion: Early gastric cancer can be detective by endoscopy and we should carefully follow up and combine with histology before and after treatment.
