Expression of vascular endothelial growth factor and its prognostic significance in gastric carcinoma

Table 1 Correlation between vascular endothelial growth factor expression and TNM stage

TNM stage	n	VEGF-poor rate (%)	VEGF-rich rate (%)
I	39	48.7	51.3
II	27	37.0	63.0
III	48	27.1	72.9a
IV	14	28.6	71.4a
