Long-term Follow-up After Endoscopic Submucosal Dissection for Early Gastric Cancer

Traditionally open-gastrectomy is the standard treatment for gastric cancer without distant
metastasis, but high mortality and morbidity, the intense weight loss, food intake
difficulties after surgery are fraught, including problems with the drawback of
significantly degrading the quality of life. Therefore, a lot of effort to seek the more
simple treatment than open gastrectomy has been made, recently the endoscopic treatment for
early gastric cancer is the most widely used treatment.

This single-arm, multi-center study enroll early gastric cancer patients after ESD compared
with the retrospective control(surgical treatment) group considering the unreality of the
randomized clinical trials. In addition, the quality of life assessment by the EORTC
C30/STO22 tools before and after ESD procedure in enrolled patients will be performed and
the direct cost analysis also will be conducted.

performed before ESD procedure
