Hematogenous or lymph node metastasis and local recurrence are the main elements related to the death of patients with colorectal carcinoma. Thus, the authors examined the microvessel count in colorectal carcinoma to determine how angiogenesis correlates with clinicopathologic factors and prognosis.
