Abstract

Vascular endothelial growth factor C (VEGF-C) is considered to be potentially lymphangiogenic and can selectively induce hyperplasia of the lymphatic vasculature. In this study, we clarified the clinicopathological features of early gastric carcinoma (EGC) that has metastasized to the lymph nodes, as well as the correlation between lymphogenous metastases in EGC and the expression of VEGF-C and VEGF. We selected 35 cases of lymph node metastasis-positive [n(+)] EGC and 70 cases of lymph node metastasis-negative [n(-)] EGC for the present study. The expression of VEGF and VEGF-C was investigated with immunohistochemical staining using monoclonal antibodies against VEGF and VEGF-C. Clinicopathologically, there were significant differences in median size (4.1 ± 2.4 vs. 2.4 ± 1.7 cm), lymphatic invasion (54 vs. 4%) and venous invasion (23 vs. 3%) between n(+) EGC and n(-) EGC. Immunohistochemically, the incidence of positive expression of VEGF-C in lymphatic invasion-positive EGC (36%) was significantly higher than that in lymphatic invasion-negative EGC (14%). The incidence of positive expression of VEGF-C in n(+) or venous invasion-positive EGC tended to be higher than that in n(-) or venous invasion-negative EGC. In conclusion, lymphatic invasion was significantly increased in VEGF-C-positive EGC.
