摘 要:目的:探讨缺氧和新生血管生成在晚期卵巢浆液性癌腹水形成和腹膜播散中的作用,及其与预后的关系。方法:用免疫组织化学方法检测HIF-1α、bFGF和CD34蛋白在72例晚期卵巢浆液性癌患者原发灶、腹水沉渣和腹腔转移灶中的表达,分析上述3种因子与预后的关系。结果:HIF-1α蛋白在晚期卵巢浆液性囊腺癌患者原发灶和转移灶中的高表达率分别为83.3%(60/72)和90.6%(48/53),高于腹水细胞中的61.3%(19/31),差异有统计学意义,P值分别为0.036和0.024;bFGF在晚期卵巢浆液性囊腺癌患者的原发灶、转移灶和腹水细胞中的表达率分别为87.5%(63/72)、100.0%(53/53)和80.6%(25/31),差异无统计学意义。残留病灶(直径>1cm)、HIF-1α、bFGF和MVD表达与晚期卵巢浆液性囊腺癌患者的复发或转移具有明显的正相关,P值分别为0.026、0.009、0.009和0.005。COX模型分析显示,MVD是晚期卵巢浆液性囊腺癌的独立预后因素,P=0.030。结论:HIF-1α和bFGF在卵巢浆液性囊腺癌腹水形成和腹膜转移中有重要作用,MVD是晚期卵巢浆液性囊腺癌的独立预后因素。OBJECTIVE: To evaluate the relationship between hypoxia and new tumor angiogenesis and peritoneal metastasis of advanced serous ovarian cancer , and their prognostic roles. METHODS: Sections from effusions and primary and metastatic lesions of 72 ovarian serous carcinoma patients were evaluated for protein expression of hypoxia-inducible factor-1α (HIF-1α) and basic-broblast factor (BFGF) by immunohistochemistry (IHC). RESULTS: HIF-1α expression showed a marked downregulation in effusions (61.3%), compared with primary (83.3%) and metastaticsites (90.6%) (P=0.036; P 0.024). Incontrast, constantly high expression of bFGF was observed in primary (87.5%), metastaticsites (100.0%) and effusions (80.6%). Residual disease mass(〉1 cm), expressions of HIF-1α and bFGF, and MVD in tumor cells were correlated with disease recurrence (P were 0. 026,0. 009,0. 009 and 0. 005, respectively). In a multivariate COX regression model, MVD was independently associated with prognosticators, P=0. 030. CONCLUSIONS: HIF-1α and bFGF play important roles in tumor peritoneal metastasis of serous ovarian cancer. MVD is an inde pendent prognostic parameter in patients with advanced serous ovarian cancer.
