ABSTRACT
In order to decide on appropriate treatment strategy against gastric cancer, an accurate preoperative evaluation of the depth of cancer invasion is essential. We studied 165 cases(19%) of early gastric cancer among 706 cases of gastric cancer. resected over a 6 year period. A retrospective study of early gastric cancer was done to evaluate the endoscopic accuracy and lymph node metastasis status, the following results were obtained 1) The proportion of EGC according to macroscopic type was 68.5% of depressed type(II, III, IIa+III, IIc+III, III+IIc, IIb+IIc), 26% of elevated type(I, IIa, IIa+ IIb, IIa+IIc), 5.5% of flat type(IIb). 2) In the view of accuracy of endoscopic diagnosis, the rate of accurate diagnosis suitable for postoperative macroscopic type was 37.5%, the rate of unsuitable typed EGC was 33.3%, overestimation(diagnosed to AGC) was 20.6% and underestimation(diagnosed to benign diseases)was 8.6%. Overall accuracy of endoscopic diagnosis was 70.8%. 3) The cases confined to the mucosa were 40.6% and others were submucosal cancers(59.4%). 4) Positive lymph node metastasis was found in 1.5% of M-cancer and 18.4% of SM-cancer(overall 11.5%). 5) Node positive rate of differentiated cancer was 10.5%, undifferentiated carcinoma was 15.4%. There was no signficant difference in frequency of nodal metastasis according tumor size and macroscopic type. 6) Tumors which satisfy the following criteria may not metastasize to lymph nodes(1) confined to the mucosa; (2) less than 2.0cm in diameter; (3) macroscopically elevated or flat; (4) histologically well or moderately differentiated.
