We examined the expression of vascular endothelial growth factor (VEGF) and microvessel counts expressed by CD34 staining in 39 patients with primary and 44 patients with metastatic liver tumors of metastatic colorectal carcinoma, and 29 patients with nonmetastatic colorectal carcinoma as control in order to determine their value in the evaluation of prognosis and recurrence after hepatectomy. Microvessel counts in primary colorectal carcinomas of the metastatic group were significantly higher than those in control (P<0.05). Neither factor correlated with any clinicopathological feature of primary or metastatic liver carcinomas. Higher microvessel counts in metastatic liver tumors tended to be associated with a shorter disease-free interval to second recurrence in the remaining liver (P = 0.069) and were significantly associated with poor prognosis after hepatectomy (P<0.05). We conclude that microvessel count is an important marker of liver metastasis and prognosis in patients with colorectal carcinoma treated with hepatectomy.
