摘要
目的研究乳腺癌人表皮生长因子受体2(Her2)和表皮生长因子受体(EGFR)高表达与生存期的关系,探讨其单独或联合作为预后指标的可行性。方法采用免疫组化检测185例乳腺癌标本的HER2和EGFR表达,并随访其生存时间。结果HER2、EGFR的阳性总表达率分别为57.8%和40.5%;HER2或EGFR过度表达均与生存时间呈负相关(P<0.05和P<0.01);HER2联合EGFR过度表达均与生存期呈负相关(P<0.05和P<0.01)。结论HER2、EGFR无论是单独或者联合高表达都降低乳腺癌患者的生存时间,可作为乳腺癌预后不良的指标。
Objective To investigate the relationship between the survival time and the high-expression of epidermal growth factor receptor (EGFR) and human epidermal receptor 2 (HER2) in breast cancer patients, and assess the feasibility of using the two markers either alone or in combination for predicting the prognosis of the patients. Methods Breast cancer samples were obtained from 185 patients and measured for the expressions of EGFR and HER-2 by way of immunohistochemistry, and 120 patients (64.9%) were followed up and their survival time recorded. Sixty-five patients (35.1%) failed to be followed for various reasons. Results Of the 120 patients followed up, death occurred in 28 (15%). Positive HER2 expression was detected in 57.8% and EGFR expression in 40.5% of the all the samples examined. The over-expression of either HER2 or EGFR was in inverse correlation with the survival time (P<0.05 and P<0.01, respectively), and the over-expression of both related to the survival time in similar manner (P<0.05 and P<0.01). Conclusion The high expression of HER2 or/and EGFR suggests a short survival time and an unfavorable prognosis.
