Objective  To investigate pattern of lymph node metastasis (LNM) in patient with early gastric cancer (EGC) and it’s relation to clinicopathologic features so as to providing evidence for proper clinical management for EGC. Method  The clinical and pathologic data of 101 EGC patients who were diagnosed and treated in the West China Hospital of Sichuan University from January 2011 to December 2012 were retrospectively analyzed. Results  The LNM was found in the 28 patients, the rate of the LNM was 27.7% (28/101). In the univariate analysis, the LNM was associated with the macroscopic type (P=0.013), depth of invasion (P<0.001), differentiation type (P=0.044), and lymphovascular invasion (P=0.020); In the multivariate logistic regression analysis, the factors including of the macroscopic type (RR=4.742, P=0.009), differentiation type (RR=6.369, P=0.011), and depth of invasion (RR=15.218, P<0.001) were the independent risk factors for the LNM. Twenty-eight patients with LNM had only 1 positive lymph node, 4 patients had more than 7 positive lymph nodes. The No.6 lymph node was the most frequently involved station (35.7%, 10/28). The LNMs in the 69.7% (19/28) patients were restricted in the extent of the D1 lymphadenectomy, 3 (10.7%) patients without the perigastric lymph node involvement had the No.8a or No.9 LNM. Conclusion  LNM in patient with EGC is correlated with clinicopathologic features such as macroscopic type, depth of invasion, differentiation type, and lymphovascular, further investigation is warranted to clarify risk factors of LNM in patient with EGC.
