This report is a clinical review of 50 cases of early gastric cancer that were treated and followed during 6 years from June 1985 to June 1990.
1) The peak incidence of age was 50 decade(38%), the mean age was 50 years, the ratio of male to female was 3 ; 2.
2) The preoperative diagnostic rate was 52% by double contrast and 60% by endoscopy and biopsy.
3) The most common size of lesions was 1.1~2 cm(32%) the smaller of lesion, the greater incidence of invasion rate to submucosa but no relation to lymph node metastasis rate.
4) The most common type of lesion was IIc(28%), the depressed type(III, IIb+c, IIc) was lymph node metastasis, but the elevated type and flat type was not lymph node metastasis, but the elevated type and flat type was not lymph node metastasis.
5) The most common histological type was moderate differentiated and signet-ring cell types (32.5%) the most common type of metastatic rate was moderate differentiated type(30.7%), the badder of differentiated type, the greater incidence of
metastatic
rate to lymph node.
6) The common sites were lower third and lesser curvature(50%). The greater incidence of metastatic rate and invasion rate to submucosa the site of posterior wall was.
7) The rate of lymph node metastasis was 6.3% in mucosa, 26.4% in mucosa and 20% in total.
8) Follow up studies were possible in 45 cases, in theses 1 case was died, 1 case was recurred but alive.
