Methods： The expressions of COX-2 and vascular endothelial growth factor （VEGF） and microvascular density （MVD） were determined with immunohistochemical methods in eighty-six NPC patients followed up over 5 years. Results： Sixty-three tumors （73.3%） were classified as COX-2 positive. COX-2 expression was positively related to VEGF expression （r=0.438, P〈0.01） and correlated with the tumor pathological grade, extent of primary lesion, lymph node metastasis, distant metastasis and shorter survival. Conclusion： Our results suggest that COX-2, being highly expressed and strongly correlated with angiogenesis in nasopharyngeal carcinoma, is apt to be used as a predictor of prognosis, including local recurrence and distant metastasis.展开更多
文摘目的:观察康莱特胶丸联合肝动脉化学栓塞(transcatheter arterial chemoembolization,TACE)治疗中晚期原发性肝癌的疗效。方法:将65例患者随机分为2组,综合组(康莱特胶丸+TACE)32例,对照组(单纯TACE)33例,比较2组近期疗效、血清甲胎蛋白(alpha fetoprotein,AFP)、外周血T淋巴细胞亚群(T lymphocyte subsets,T-LS)、生活质量(quality of life,QOL)、肿瘤进展时间(time to progession,TTP)和不良反应。结果:综合组客观有效率、血清AFP与对照组相仿(P>0.05),T-LS(CD3+、CD4+、CD4+/CD8+细胞比值)、QOL、TTP、肝脏不良反应等方面明显优于对照组,差异有统计学意义(P<0.05)。结论:康莱特胶丸联合TACE是治疗失去手术治疗机会的原发性肝癌的有效方法之一。
