bFGF在恶性肿瘤中的表达及其临床病理意义

Expression of b FGF in malignant tumor and its clinical pathological significance

目的:检测临床常见恶性肿瘤(非小细胞肺癌、乳腺癌、结肠癌和黑色素瘤)组织中碱性成纤维细胞生长因子(b FGF)的表达情况,并分析其与恶性肿瘤临床病理学特征之间的相关性。方法:采用免疫组织化学SP技术检测208例原发性恶性肿瘤(肺癌68例,乳腺癌80例,结肠癌41例和黑色素瘤19例)石蜡包埋组织中b FGF蛋白的表达水平。结果:在肺癌中b FGF蛋白高表达多见于伴有淋巴结转移的低分化患者,与肿瘤原发灶大小、淋巴结受累、远处转移(TNM)分期呈正相关,且b FGF的表达对患者中位生存期无明显影响;在乳腺癌中,b FGF高表达多见于伴淋巴结转移的晚期患者;在结肠癌中b FGF蛋白表达多见于伴有区域淋巴结转移的中高分化患者;此外,在晚期有淋巴结转移的黑色素瘤患者中,b FGF蛋白呈高表达。结论:b FGF可能参与了临床常见恶性肿瘤的发生和演变过程,b FGF蛋白表达可能成为判断恶性肿瘤是否发生转移的有效参考指标之一。

AIM： To detect basic fibroblast growth factor （ bFGF ） expression in clinical common malignant tumor （ non-small-cell lung cancer,breast cancer, colon cancer and melanoma） , and to identify relationship between the expression and tumor clinicopathological characteristics.METHODS：Immunohistochemical SP method was used to detect the expression of bFGF at protein level in 208 cases of paraffin-embedded tissue of primary malignant tumor patients （ 68 cases of lung cancer, 80 cases of breast carcinoma, 41 cases of colon cancer and 19 cases of melanoma） .RESULTS：The bFGF protein expression levels were significantly higher in low differentiated non-small-cell lung cancer with lymph node metastasis, and were positively correlated with TNM.In addition, no significant influence of the bFGF protein expression on the patients with median survival period was observed.The protein expression of bFGF was higher in advanced breast cancer with lymph node metastasis and was commonly found in the middle/higher differentiated colon cancer with regional lymph node metastasis.Meanwhile, bFGF protein was highly expressed in advanced melanoma patients with lymph node metastasis.CONCLUSION：bFGF may participate in the process of occurrence and progression of malignant tumor.Ex-pression of bFGF protein may be an effective parameter for evaluating metastasis and prognosis of malignant tumor.
