침윤성 자궁경부암에서 맥관형성에 관한 연구

Abstract

Objective: Tumor angiogenesis is believed to conelate with tumor growth, progression and metastasis. Studies of angiogenesis in breast, prostate and melanoma have shown that angiogenesis, the induction of new capillaries and venules, is associated with tumor metastases and recurrences. The purpose of this study was to investigate the angiogenesis as a prognostic factor in invasive cervical cancer. Methods: Forty-three formalin fixed embedded blocks of invasive cervical cancers were examined using immunohistochemical staining with a monoclonal antibody against factor VIII-related antigen. Results: The miaovessel counts were 53.50+-20,07 in patients with lymph node metastasis, and 45.97+-28.12 in those without such metastasis. There was a trend for the microvessel count to increase with lymph node metastasis. However, thae was no significant difference in microvessel counts regarding node status. There was no significant difference between microvessel counts in patients with stage I(47.90+-25.89) and those with stage Il(45.50+-29.27), The microvessel counts in squamous cell carcinoma(46.54+-27.79) were not significantly different from those in adenocarcinoma(47,50+-27.05), The microvessel count in patients with tumor size >-4 cm(53.00+-21.17) was not significantly higher than in those with tum#ar size <4 cm(46.20+-27.94). Conclusion: There was no significant correlation between microvessel counts and clinical stage of disease, pathological type, tumor size or lymph node metastasis in patients with invasive cervical cancer. There was a trend for the microvessel count to increase with lymph node etastasis.
