摘要 目的:探讨从腹腔游离癌细胞中分离胃癌干细胞的可行性及其意义。方法:随机选择35例胃癌患者,术中发现有腹膜转移5例,无腹膜转移30例。用流式细胞仪检测腹腔灌洗液中CD44和CK20的表达,并比较有、无腹膜转移两组之间差别是否有差异。结果:⑴有、无腹膜转移组之间腹腔游离癌细胞中CD44+CK20+差异有统计学意义(P=0.009);⑵CD44在胃癌组织中的阳性表达率为36.8%,胃癌组织中CD44阳性表达率与浆膜浸润、淋巴结转移等病理因素有关;该两因素分组间差异有统计学意义(P=0.000)。结论:从胃癌腹腔灌洗液游离癌细胞中分离胃癌干细胞是可行的,这种可行性为人胃癌干细胞的分离提供了新的思路,为制定胃癌腹膜转移的靶向治疗提供了一定的实验基础。
