葡萄糖转运蛋白1、人类血管内皮生长因子C、核因子κB在乳腺浸润性导管癌组织中的表达及其对患者预后的影响

目的 探讨葡萄糖转运蛋白1(GLUT-1)、人类血管内皮生长因子C(VEGF-C)、核因子κB(NF-κB)在乳腺浸润性导管癌组织中的表达及其对患者预后的影响。方法 回顾性研究。纳入2011年1月-2014年11月蚌埠市第三人民医院117例乳腺浸润性导管癌患者(年龄20~79岁)的临床资料及癌组织病理学标本,并随机采集其中51例患者的癌旁组织标本。以免疫组织化学法检测标本中GLUT-1、VEGF-C、NF-κB的表达,比较其在癌组织和癌旁组织中表达量的差异,分析阳性表达与浸润性导管癌临床病理因素的关系,及其对临床预后的影响。结果 GLUT-1、NF-κB、VEGF-C在浸润性导管癌组织中阳性表达率高于癌旁组织,差异均有统计学意义(χ²=45.785、48.433、48.236, P值均<0.01)。GLUT-1、NF-κB、VEGF-C在不同肿瘤大小、有无淋巴浸润、不同TNM分期和病理分级患者阳性表达率的差异均有统计学意义(P值均<0.05)。117例浸润性导管癌患者中,失访7例,死亡32例。110例随访的乳腺浸润性导管癌患者中,GLUT-1阳性表达患者的5年生存率(21.82%)显著低于阴性表达患者(77.09%),差异有统计学意义(χ²=10.854,P<0.01);NF-κB、VEGF-C阳性表达与阴性表达患者5年生存率差异均无统计学意义(χ²=0.843、0.852,P值均>0.05)。结论 GLUT-1、VEGF-C、NF-κB表达升高可能参与了乳腺浸润性导管癌的侵袭进展过程,其中GLUT-1是影响患者预后的高风险因素。

Expression and clinical significance of glucose transporter 1, vascular endothelial growth factor C,and nuclear faetor-κB in invasive ductal carcinoma of the breast

Objective To observe the expression and clinical significance of glucose transporter 1(GLUT-1), vascular endothelial growth factor C(VEGF-C), nuclear faetor-κB(NF-κB)in invasive ductal carcinoma of the breast.Methods The expression of GLUT-1, VEGF-C, and NF-κB in 117 cases of invasive ductal carcinoma and 51 cases of pericarcinous tissues collected from January 2011 to November 2014 was detected by immunohistochemistry. The patients were aged 20-79 years. The relationship between the expression of GLUT-1, VEGF-C, and NF-κB and the clinicopathological characteristics and survival times of the patients was then analyzed.Results Differences in GLUT-1, NF-κB, and VEGF-C expression in normal tissues, ductal hyperplasia, ductal carcinoma in situ, invasive ductal carcinoma, and breast tissue with lymph node metastasis were statistically significant (χ²=45.785, 48.433, 48.236, all P values<0.01). The positive expression rates of GLUT-1, NF-κB, and VEGF-C were correlated with tumor size, lymphatic infiltration, TNM stage, and pathological grade (all P values<0.05). Of the 117 patients with invasive ductal carcinoma, 7 were lost to follow up and 32 passed away. Among 110 patients with infiltrating ductal carcinoma of the breast, the 5-year survival rate of patients with positive GLUT-1 expression (21.82%) was notably lower than that of patients with negative expression (77.09%); the difference observed was statistically significant (χ²=10.854,P<0.01). No significant difference in 5-year survival rate between patients with positive and negative NF-κB and VEGF-C expression was observed (χ²=0.843, 0.852, all P values>0.05).Conclusions Increased expression of GLUT-1, VEGF-C, and NF-κB may be involved in the invasion and progression of infiltrating ductal carcinoma of the breast. Moreover, GLUT-1 is a high-risk factor affecting the prognosis of patients.
