Abstract
AIM: To find risk factors of lymph node metastasis
(LNM) in early gastric cancer (EGC) and to find proper
endoscopic therapy indication in EGC.
METHODS: We retrospectively reviewed the 2270
patients who underwent curative operation for EGC
from January 2001 to December 2008. EGC was
defined as malignant lesions that do not invade beyond
the submucosal layer of the stomach wall irrespective
of presence of lymph node metastasis.
RESULTS: Among 2270 enrolled patients, LNM was
observed in 217 (9%) patients. LNM in intramucosal
(M) cancer and submucosal (SM) cancer was detected
in 38 (2.8%, 38/1340) patients and 179
(19%, 179/930) patients, respectively. In univariate
analysis, the risk factors for LNM in EGC were size of
tumor, Lauren classification, ulcer, lymphatic invasion,
vascular invasion, and depth of invasion. However,
in multivariate analysis, size of tumor, lymphatic
invasion, vascular invasion, and depth of invasion were
risk factors for LNM in EGC. Size of tumor, lymphatic
invasion, vascular invasion, and depth of invasion were
risk factors for LNM in cases of intramucosal cancer
and submucosal cancer. In particular, there was no
lymph node metastasis in cases of well differentiated
early gastric cancer below 1 cm in size without ulcer
regardless of lymphovascular invasion.
CONCLUSION: Tumor size, perilymphatic-vascular
invasion, and depth of invasion were risk factors for
LNM in EGC. There was no LNM in EGC below 1 cm
regardless risk factors.
