摘要 目的探讨凝溶胶(GSN)蛋白在结直肠癌、癌旁正常组织和淋巴结转移癌组织中的表达水平及其临床意义。方法运用免疫组化方法(Envision法)检测69例结直肠癌组织(原发癌组)、癌旁正常组织(癌旁正常组)和35例淋巴结转移癌组织(淋巴结转移癌组)中的GSN蛋白表达情况。结果 GSN蛋白在癌旁正常组织、原发癌组织和淋巴结转移癌组织中的表达水平差异有统计学意义(P<0.01),癌旁正常组中的GSN蛋白表达水平高于原发癌组和淋巴结转移癌组,而原发癌组和淋巴结转移癌组的比较差异无统计学意义(P=0.406)。GSN蛋白的表达水平与结直肠癌的分化程度、TNM分期和有无淋巴结转移相关,低分化结直肠癌GSN蛋白表达水平明显高于中高分化结直肠癌(P=0.009),晚期结直肠癌(Ⅲ+Ⅳ)中GSN蛋白表达水平明显高于早期结直肠癌(Ⅰ+Ⅱ)(P=0.001),伴有淋巴结转移患者GSN表达水平明显高于不伴淋巴结转移患者(P=0.001)。结论结直肠癌早期,GSN蛋白表达水平的降低可能与肿瘤的形成有关,而随着肿瘤进展到晚期,GSN蛋白表达水平升高,与肿瘤的恶性行为有关。
