目的:研究半乳糖凝集素-3( Galectin-3)在大肠癌中的表达,并探讨其在大肠癌进展过程中的意义,旨在为临床诊断、治疗、预后提供新的理论依据。方法:应用免疫组化法检测52例大肠癌组织、20例大肠腺瘤和20例大肠正常粘膜组织中Galectin-3的表达情况,分析其表达结果与患者的性别、年龄、肿瘤发生部位、肿瘤组织分化程度、浸润程度及淋巴结转移之间关系。实验资料的统计学处理通过SPSS13.0统计软件完成,等级资料采用秩和检验,以P<0.05为差异有统计学意义。结果:①Galectin-3在大肠正常黏膜、大肠腺瘤和大肠癌中均有阳性表达,表达强度依次增加,三组之间阳性表达率差异有统计学意义( P<0.01)。②Galectin-3在浸润程度深的大肠癌组织的表达明显高于浸润程度浅的(P<0.01);Galectin-3在低分化大肠癌中的表达则高于高分化和中等分化的(P<0.05);Ga-lectin-3有淋巴结转移的大肠癌组织中的表达明显高于无淋巴结转移的( P<0.01)。 Galectin-3在不同性别、年龄(≤60,>60)及肿瘤发生部位的表达则无明显差异( P>0.05)。结论:大肠癌组织中Galec-tin-3的表达水平明显高于正常大肠黏膜组织,提示Galectin-3的高表达在大肠癌的发生、发展过程中起到了重要的作用。 Galectin-3在大肠癌不同浸润深度、不同分化程度及有无淋巴结转移中的表达有显著差异,提示上述指标在大肠癌的浸润、生长及远处播散过程中起到了一定的作用,并可作为判断大肠癌转移及预后的预测因素。
目的:研究半乳糖凝集素-3( Galectin-3)在大腸癌中的錶達,併探討其在大腸癌進展過程中的意義,旨在為臨床診斷、治療、預後提供新的理論依據。方法:應用免疫組化法檢測52例大腸癌組織、20例大腸腺瘤和20例大腸正常粘膜組織中Galectin-3的錶達情況,分析其錶達結果與患者的性彆、年齡、腫瘤髮生部位、腫瘤組織分化程度、浸潤程度及淋巴結轉移之間關繫。實驗資料的統計學處理通過SPSS13.0統計軟件完成,等級資料採用秩和檢驗,以P<0.05為差異有統計學意義。結果:①Galectin-3在大腸正常黏膜、大腸腺瘤和大腸癌中均有暘性錶達,錶達彊度依次增加,三組之間暘性錶達率差異有統計學意義( P<0.01)。②Galectin-3在浸潤程度深的大腸癌組織的錶達明顯高于浸潤程度淺的(P<0.01);Galectin-3在低分化大腸癌中的錶達則高于高分化和中等分化的(P<0.05);Ga-lectin-3有淋巴結轉移的大腸癌組織中的錶達明顯高于無淋巴結轉移的( P<0.01)。 Galectin-3在不同性彆、年齡(≤60,>60)及腫瘤髮生部位的錶達則無明顯差異( P>0.05)。結論:大腸癌組織中Galec-tin-3的錶達水平明顯高于正常大腸黏膜組織,提示Galectin-3的高錶達在大腸癌的髮生、髮展過程中起到瞭重要的作用。 Galectin-3在大腸癌不同浸潤深度、不同分化程度及有無淋巴結轉移中的錶達有顯著差異,提示上述指標在大腸癌的浸潤、生長及遠處播散過程中起到瞭一定的作用,併可作為判斷大腸癌轉移及預後的預測因素。

Objective:To study the expression of Galectin-3 in colorectal carcinoma , and to investigate its in colorectal cancer progression of meaning in the course , designed for clinical diagnosis , treatment , prog-nosis and provide a new theoretical basis .Method: Detected the expression of Galectin-3 in 52 cases of colorectal cancer , 20 cases of colorectal adenoma and 20 cases of colorectal normal mucosa tissue through the application of immunohistochemistry .Analyzed the relationship between its expression with the patient ’s sex, age, tumor location, tumor differentiation, infiltration and lymph node metastasi .Result: ①Galectin-3 in colorectal normal mucosa , colorectal adenoma and carcinoma showed positive expression , and the expression intensity increases , positive expression rate had a significant difference ( P<0.01) among three groups .②Ga-lectin-3 in infiltration over the muscle layer of the colorectal carcinoma was higher than that of infiltration does not exceed the muscular layer of the colon cancer tissue ( P<0.01);Galectin-3 in poorly differentiated colorectal carcinoma was higher than that of well-differentiated and moderately differentiated colorectal canc-er tissue ( P<0.05 ); Galetctin-3 in lymph node metastasis of colorectal cancer tissues than those without lymph node metastasis in colorectal cancer tissue (P<0.01).Conclusion: The expression of Galectin-3 in colorectal carcinoma is higher than that in normal colorectal mucosa .It suggests that the higher expression of Galectin-3 play an improtant role in the development of colorectal carcinoma .The expressions of Galectin-3 is significantly correlated with depth of invasion , lymph node metastasis and degree of differentiation in color-ectal carcinoma .So they could be a predictive and prognostic factor of colorectal carcinoma .
