摘要 目的探讨高级别人膀胱癌组织中肿瘤相关巨噬细胞(TAMs)和血管内皮生长因子(VEGF)的表达,并对二者的相关性进行研究.方法 64例高级别膀胱癌患者,所有患者均行全膀胱切除术,进行膀胱正常组织和膀胱癌组织标本的切除,分别用CD68和CD34对巨噬细胞(CD68+)和微血管密度进行标记,检测微血管密度计数、TAMs的表达和浸润程度、VEGF表达,并进行对比分析.结果膀胱癌组织的CD68+TAMs表达等级高于膀胱正常组织,差异有统计学意义(U=8.152,P<0.05).膀胱癌组织的VEGF阳性表达率为53.1%显著高于膀胱正常组织的6.3%,差异具有统计学意义(χ2=33.684,P<0.05).Pearson相关性检验显示,膀胱癌组织中VEGF与CD68+TAMs表达呈显著正相关关系(r=0.811,P<0.05).膀胱癌组织的微血管密度总体计数为(56.8±12.9)显著高于膀胱正常组织的(7.2±1.5),差异具有统计学意义(t=30.544,P<0.05).膀胱癌组织中,微血管密度计数随着CD68+TAMs表达级别的升高而升高.Pearson相关性检验显示,膀胱癌组织中微血管密度计数与CD68+TAMs表达呈显著正相关关系(r=0.786,P<0.05).结论 TAMs与VEGF表达呈正相关性,且在膀胱癌组织中高度表达,加强这两项指标的检测,可为膀胱癌的诊治提供基础,进行预后情况的预测.
