The overall rate of curative resection for expanded indication undifferentiated type EGCs was only 42%. Especially, the curative resection rate in PD type EGCs was less than one third.

When we compare the characteristics between the curative resection lesions and non-curative resection lesions, there were no differences in terms of age, sex, location and gross type. However, the size in the curative resection group was smaller than the non-curative resection group. The size discrepancy between endoscopy size and pathology size was only 0.14 cm in curative resection group, but the size discrepancy was 1.5 cm in the non-curative resection group. This size discrepancy was one of the major reasons of non-curative resection.

This graph shows the reasons of non-curative resection in out ESD simulation. The most common reason was the size larger than 2 cm, followed by SM invasion and LV invasion.

There were three cases with lymph node metastasis in the curative resection group. Two were PD-type and one was SRC-type in the forceps biopsy. In the final surgical pathology, they was PD type mucosal cancers with SRC components larger than 1.0 cm.

Because the size was the most common reason of non-curative resection, we modified the expanded indication criteria into 1.5 cm, 1 cm and 0.6 cm. When a size criterion of 1 cm was applied, the number of ESD candidates were decreased by 51.4% and the curative resection rate was increased into 54%. However, this increase in the curative resection rate was mostly seen in the SRC type EGCS. The curative resection rate in PD type was almost the same in the smaller lesions.
