摘 要:[目的] 探讨Gal-3蛋白在结直肠癌中的表达及临床意义。[方法] 采用免疫组织化学SP法检测Gal-3蛋白在60例结直肠癌组织的表达;另取癌旁正常黏膜20例及结直肠腺瘤20例作为对照组。[结果] 结直肠癌中Gal-3蛋白的表达明显高于癌旁正常黏膜和结直肠腺瘤(55.0%,10.0%和25.0%,P<0.05)。Gal-3蛋白在侵及浆膜外、TNM Ⅲ+Ⅳ期、有淋巴结转移组中的表达明显高于未侵及浆膜外(P<0.05)、TNM Ⅰ+Ⅱ期(P<0.01)、无淋巴结转移组(P<0.05);与年龄、性别、肿瘤大小和分化程度无关。Gal-3蛋白阳性表达患者5年生存率明显低于阴性表达者(P<0.05)。[结论] Gal-3蛋白在结直肠癌中高表达,其可能在结直肠癌的发生发展和浸润转移中起作用,并提示预后不良。 |

Abstract:[Purpose] To investigate the expression of Gal-3 protein in colorectal cancer and its clinical significance. [Methods]The expression of Gal-3 protein in 60 cases with colorectal cancer was detected by immunohistochemistry (SP method),and 20 normal adjacent mucosa and 20 colorectal adnoma as control group were served. [Results] The positive rate of Gal-3 protein in colorectal cancer was significantly higher than that in normal adjacent mucosa and colorectal adnoma (55.0%,10.0% and 25.0%,P<0.05). the Gal-3 protein expression level in outside the serosa invasion,lymph node metastasis and TNM stages III+IV group was significantly higher than that in within the serosa(P<0.05),lymph node metastasis-free group(P<0.05) and TNM stage I+II group(P<0.01).And Gal-3 protein expression was not related to age,gender,tumor size and differentiation (P>0.05).The 5-year survival rate of the patients with positive expression of Gal-3 protein was significant lower than that with negative expression of Gal-3 protein (P<0.05).[Conclusion] Gal-3 protein is overexpressed in colorectal cancer,it might play an important role in the carcinogenesis and development of colorectal cancer,and indicates poor prognosis. |
