ObjectiveTo investigate the relationship between vascular endothelial growth factor receptor-3 (VEGFR-3) and clinical pathology of gastric carcinoma(GC).MethodsThe expression of VEGFR-3 in 80 GCs and 20 gastric benign tissues (GBT) was detected by immunohistochemistry(SP), by which the density of lymphatic vessels (DLV) was calculated. ResultsThe DLV in GC was （5.800 0±2.318 9）/×200, in GBT （2.380 0±0.462 9）/×200(P=0.000); in GC with lymph node metastasis （6.948 3±1.583 1）/×200, without lymph node metastasis （2.772 7±0.428 9）/×200 （P=0.000）. In poorly differentiated type group, DLV was （7.681 8±0.982 9）/×200, higher than that in moderately and highly differentiated type group 〔(3.500 0±1.028 2）/×200, P=0.000〕. DLV in pTNM Ⅰ+Ⅱ was （4.291 7±1.688 0）/×200, in Ⅲ+Ⅳ （8.062 5±0.759 4）/×200 （P=0.000）.ConclusionDLV shows positive relations with pTNM stage, differentiation and lymph node metastasis of GC.
