摘要: BACKGROUND Angiogenesis is reportedly correlated with metastasis, relapse, and prognosis in some types of tumors. Hematogenous or lymph node metastasis local recurrence are the main elements related to death patients colorectal carcinoma. Thus, authors examined microvessel count carcinoma determine how angiogenesis correlates clinicopathologic factors prognosis. METHODS Paraffin embedded sections from 166 primary carcinomas that had been completely removed were analyzed for angiogenesis. Vessels stained anti-factor VIII polyclonal antibody, areas most discrete microvessels counted a 400× field. RESULTS Tumor size was significantly count. Microvessel counts lymphatic vessel invasion, venous relapse higher than those without. Furthermore, an independent prognostic factor (P = 0.007), whereas Dukes stage more significant value < 0.001) according multivariate Cox hazard analysis. CONCLUSIONS This study suggested assessed by marker Cancer 1996;78:226-31.
