HMGB1和VEGF-C/D在结肠癌组织中的表达及与淋巴结转移之间的关系

目的探讨HMGB1和血管内皮生长因子C/D(VEGF-C/D)在人结肠癌组织中的表达及与淋巴结转移之间的关系.方法选择45例结肠癌标本,应用免疫组织化学染色方法,检测HMGB1和VEGF-C/D在人结肠癌组织中的表达,同时对其与临床病理参数的关系进行统计学分析.结果 HMGB1在结肠癌组织中的阳性表达率为73.3%,其中有淋巴结转移的表达率为85.2%,无淋巴结转移的表达率为55.6%,差异有统计学意义.VEGF-C结肠癌组织中的阳性表达率为60%,其中有淋巴结转移的表达率为74%,无淋巴结转移的表达率为38.9%,二者差异显著.而且,HMGB1表达与VEGF-C表达呈正相关.结肠癌HMGB1和VEGF-C的表达水平与肿瘤细胞淋巴转移相关,而与患者的年龄、性别、分化程度等无相关性.结论 HMGB1和VEGF-C的表达与结肠癌患者的淋巴结转移相关,可作为判断预后的一个观测指标.

Correlation between high mobility group protein 1, VEGF-C/D expressions and lymph node metastasis in colon cancer

Objective To discuss the correlation between the expressions of high mobility group protein box 1(HMGB1),VEGF-C/D and lymph node metastasis in colon cancer.Methods Forty-five colon cancer samples were stained by immunohistochemical method for VEGF-C/D,HMGB1.The correlations of VEGF-C/D,HMGB1 expressions and lymph node metastasis were analyzed statistically.Results Positive HMGB1 expression was in 33 specimens,lymph node metastasis was in 27 specimens with 23 specimens of positive HMGB1 and non-lymph node metastasis was in 18 specimens with 10 specimens of positive HMGB1.Positive VEGF-C expression was in 27 specimens with 20 in lymph node metastasis.The expression of HMGB1 was consistent with VEGF-C expression,and HMGB1 and VEGF-C expressions were closely correlated with lymph node metastasis,but not with age,sex,cellular differentiation.Conclusion HMGB1 and VEGF-C expression may become predictor to the prognosis of colon cancer patients.
