【摘要】Objective To investigate the expressions of vascular endothelial growth factor (VEGF)-C,-D and VEGF receptor-3 (VEGFR-3/Flt-4) in pN0 early gastric cancer (ECG) and their relationship with lymph node micrometastasis.Methods From January 2005 to January 2010,the paraffin-embedded specimens of 61 pN0 ECG were collected.The expressions of VEGF-C,VEGF-D and VEGFR-3 in 61 pN0 early gastric cancer tissue,25 adjacent tissue and CAM5.2 expression in 868 hematoxylin-eosin staining negative lymph nodes were detected by immunohistochemical assay.The rate of lymph node micrometastasis of 61 pN0 ECG was evaluated.According to the data type,t test,x2 test or Fisher exact probability were performed for the relationship analysis between the expressions of VEGF-C,VEGF-D and VEGFR-3 in pN0 stage ECG and lymph node micrometastasis.Results The high expressions of VEGF-C,VEGF-D and VEGFR-3 in the 61 pN0 ECG were 34.4％ (21/61),34.4％ (21/61) and 44.3％ (27/61) respectively,which were higher than those of adjacent tissues [12.0％ (3/25),8.0％ (2/25) and 16.0％ (4/25) respectively] (x2=4.433,6.321 and 6.144 respectively,all P＜
