目的 探讨血氧水平依赖功能磁共振成像(BOLD-fMRI)的R2*值与乳腺浸润性导管癌组织葡萄糖转运蛋白1 (GLUT-1)表达的相关性.方法 回顾性分析2011年12月至2013年6月本院接受乳腺癌手术治疗且术后病理证实为乳腺浸润性导管癌患者77例的临床资料,所有患者均于术前行乳腺BOLD-fMRI检查并测定肿瘤组织的R2*值.免疫组化染色检测肿瘤组织GLUT-1的表达.Spearman相关分析肿瘤组织BOLD-fMRI R2*值与GLUT-1表达的关系.结果 病理学检查显示77例患者均为乳腺浸润性导管癌,肿瘤分级为Ⅰ级3例、Ⅱ级48例、Ⅲ级26例,其中伴腋窝淋巴结转移40例.免疫组化显示肿瘤组织GLUT-1表达阴性6例、弱阳性11例、中度阳性25例、强阳性35例,GLUT-1表达阳性率为92.2％(71/77).腋窝淋巴结转移组GLUT-1表达显著高于无腋窝淋巴结转移组(x2=5.718,P=0.016).BOLD-fMRI检查显示乳腺浸润性导管癌呈混杂信号,R2*值为26.4～90.5 Hz,平均(54.9±16.9)Hz.Spearman相关分析表明,乳腺浸润性导管癌肿瘤组织R2*值与GLUT-1的表达呈正相关(r=0.587,P=0.000).结论 BOLD-fMRI可用于无创性评价乳腺浸润性导管癌组织慢性乏氧及葡萄糖代谢水平.

Objective To investigate the correlation between R2* value of blood oxygenation leveldependent functional magnetic resonance imaging (BOLD-fMRI) and glucose transporter-1 (GLUT-1) of breast invasive ductal carcinoma (IDC).Methods Clinical data of 77 women who underwent breast cancer surgery in our hospital and were pathologically confirmed to be with IDC between December 2011 and June 2013 were retrospectively analyzed.Before surgery,these patients received BOLD-fMRI with measurement of tumor R2* value.The expression of GLUT-1 in cancer tissues was evaluated by immuuohistochemical analysis.Spearman correlation analysis was performed on the relationship between BOLD-fMRI R2* value and GLUT-1 expression in the cancer tissues.Results Pathological study identified IDC in all of the 77 patients,including 3 with grade Ⅰ,48 with grade Ⅱ and 26 with grade Ⅲ lesions.Axillary metastasis was detected in 40 patients.GLUT-1 expression of cancer tissues was negative in 6 cases,weak-positive in 11,moderatepositive in 25,and strong-positive in 35 cases,corresponding to a positive rate of 92.2％ (71/77).Patients with axillary metastasis had significantly stronger GLUT-1 expression than those without axillary metastasis (x2=5.718,P=0.016).IDCs showed relatively heterogeneous intensity on BOLD-fMR images.The mean R2* value of 77 lesions was (54.9± 16.9) Hz (range:26.4 to 90.5 Hz).R2* value was positively correlated with the expression of GLUT-1 (r=0.587,P=0.000) by Spearman correlation analysis.Conclusion BOLD-fMRI can be used for non-invasive evaluation of the chronic hypoxia and glucose metabolism in IDC tissue.
