摘要 目的探讨CD68^+肿瘤相关巨噬细胞(TAMs)在结直肠癌组织中的表达和预后的关系。方法选取行手术治疗的结直肠癌患者的肿瘤组织和癌旁组织标本共120例,通过免疫组化检测TAMs标记物CD68^+在肿瘤组织和癌旁组织的浸润情况,对比肿瘤组织和癌旁组织CD68^+巨噬细胞的细胞密度,分析肿瘤组织中CD68^+巨噬细胞的细胞密度与临床特征的关系,对比不同CD68^+巨噬细胞浸润密度的结直肠癌患者的预后情况。结果肿瘤组织CD68^+ TAMs浸润细胞数显著高于癌旁组织,差异有统计学意义(t=16.033,P<0.001),结直肠癌组织中CD68^+ TAMs细胞密度与临床特征的关系中,其TNM分期Ⅰ~Ⅱ期、区域淋巴结没有转移、没有远处转移和病理分级为Ⅰ~Ⅱ患者的CD68^+ TAMs高表达比例显著高于CD68^+ TAMs低表达的比例(P<0.05),Kaplan-Meier生存曲线结果显示CD68^+ TAMs高表达患者的总体生存率(OS)和无病生存率(DFS)显著优于CD68^+ TAMs低表达的患者,差异有统计学意义(OS:HR=0.429,P=0.013; DFS:HR=0.424,P=0.006)。结论结直肠癌组织较正常结肠组织中CD68^+ TAMs细胞数显著增多,且癌组织CD68^+ TAMs与肿瘤分期、病理分级、淋巴结及远处转移密切相关,高CD68^+ TAMs表达患者具有更好的临床预后。
