摘要 目的:探讨前列腺癌(PCa)中局灶性及转移性PCa组织中集落刺激因子受体4(CXCR4)的表达与意义。方法:使用免疫组织化学染色方法分别检测25例局灶性PCa组织和11例转移性PCa转移灶组织,以及10例前列腺增生(BPH)组织中表达CXCR4的阳性细胞数。分析其与前列腺癌转移、病理分级、临床分期的关系。结果:与BPH比较,CXCR4在局灶性及转移性PCa组织中的表达明显增高,转移性PCa组织中CXCR4的表达明显高于局灶性PCa组织的表达(P<0.05);在不同病理分级PCa组织中,从高分化组到低分化组CXCR4阳性细胞数明显增多,差异有统计学意义(P<0.05);CXCR4在Whitmore-Jewett分期系统C+D期组的表达明显高于A+B期组,差异有统计学意义(P<0.05)。结论:PCa组织中,尤其是转移性PCa组织中的CXCR4高表达,其表达随PCa病理分级及临床分期进展而增多。在PCa发生发展过程中CXCR4的表达可能作为PCa转移趋势及预后随访判定转移的新指标。
