459例乳腺癌患者21基因复发风险评分的临床意义林佳菲;吴佳毅;蔡刚;吴蓓颖;林琳【摘要】Objective To investigate the distribution characteristics of 21-gene recurrence score and its correlation with clinicopathologic characteristic in breast cancer patients,and to evaluate the role in the choice of adjuvant chemotherapy. Methods A total of 459 patients with breast cancer were enrolled,who are with positive estrogenreceptor(ER)and negative human epidermal growth factor receptor2(HER2). RNA was extracted from the paraffin specimens of patients. Real-time fluorescence polymerase chain reaction(PCR)was used to determine the expression of 21-gene,and recurrence score was calculated. According to recurrence score,the patients were classified into low,intermediate and high risk groups. The relationship with clinicopathologic characteristic and the choice of adjuvant chemotherapy in recurrence score groups were evaluated. Multivariate Logistic regression analysis was used to analyze the influence factors for recurrence score. Results Among the 459 patients with breast cancer, there were 117 patients(25.5%)in low risk group,254 patients(55.3%)in intermediate risk group and 88 patients (19.2%)in high risk group. There was statistical significance in tumor grade,type,progestin receptor(PR)status and Ki67 expression among recurrence scoregroups(P<0.05). Multivariate Logistic regression analysis showed that PR status and tumor grade were influence factors for recurrence score. There were differences in the proportions of receiving adjuvant chemotherapyamong recurrence score groups(P<0.05). Conclusions Recurrence score can effectively integrate some important conventional clinical and pathological indicators,and provide more information. Recurrence score can also support the choice of adjuvant chemotherapy.%目的探讨乳腺癌21基因复发风险评分的分布情况及其与临床病理特征的相关性,同时探讨21基因复发风险评分在辅助化疗选择中的意义.方法选取接受手术治疗的459例雌激素受体(ER)阳性、人类表皮生长因子受体2(HER2)阴性的乳腺癌患者.提取患者石蜡标本RNA,采用实时荧光聚合酶链反应(PCR)检测21基因(16个乳腺癌相关基因和5个参考基因)的表达,计算21基因复发风险评分并以此分为低危组、中危组和高危组.比较不同21基因复发风险评分亚组与常规临床病理特征的关系以及在辅助化疗选择上的区别,采用多因素Logistic回归分析评估21基因复发风险评分的影响因素.结果 459例乳腺癌患者中低危组117例(25.5%)、中危组254例(55.3%)、高危组88例(19.2%),各组组织学分级、分子分型、孕激素受体(PR)状态及Ki67表达差异均有统计学意义(P<0.05).多因素Logistic回归分析显示PR状态和组织学分级是21基因复发风险评分危险度分组的影响因素.低危组、中危组和高危组接受化疗的比例有明显差异(P<0.01).结论 21基因复发风险评分能有效整合一些重要的常规临床病理指标,并提供更多的信息,可以为辅助化疗的选择提供支持.【期刊名称】《检验医学》【年(卷),期】2017(032)007【总页数】7页(P590-596)【关键词】21基因;复发风险评分;临床病理特征;辅助化疗;乳腺癌【作者】林佳菲;吴佳毅;蔡刚;吴蓓颖;林琳【作者单位】上海交通大学医学院附属瑞金医院检验科,上海 200025;上海交通大学医学院附属瑞金医院乳腺疾病诊治中心,上海 200025;上海交通大学医学院附属瑞金医院检验科,上海 200025;上海交通大学医学院附属瑞金医院检验科,上海200025;上海交通大学医学院附属瑞金医院检验科,上海 200025【正文语种】中文【中图分类】R446.1乳腺癌是女性发病率最高的恶性肿瘤。
《中国癌症杂志》2009年第19卷第12期 CHINA ONCOLOGY 2009 Vol.19 No.1295321基因Oncotype Dx对乳腺癌预后研究的进展 [摘要] 目前最为有效的乳腺癌治疗模式是多学科综合标准化治疗。
然而长期以来缺乏有效的预后预测手段来指导患者的个体化治疗,以至于相当一部分化疗获益甚少的低风险患者也不得不接受化疗。
随着基因组学的发展,已有数个基因系列的检测结果被证实可以用于乳腺癌预后的预测,进而判断测患者从化疗中的获益,避免过度治疗。
21基因Oncotype Dx检测正是其中之一,其有效性及准确性已在各种临床研究中得到了证实。
本文就21基因Oncotype Dx对乳腺癌预后研究的进展进行综述。

However, there are no effective models that can accurately predict prognosis, so that no guidance of individualized treatment has yet been set up, resulting in a proportion of patients with low risk who received chemotherapy with little benefit . With the development of genomics, several gene sets have been demonstrated to be helpful in predicting of breast cancer prognosis and grading the patients’ benefit from chemotherapy, thus avoid overtreatment. 21-gene Oncotype Dx was reported as one of them and has been demonstrated to be effective and accurate in various clinical studies. This paper summarizes researches on 21-gene Oncotype Dx in breast cancer.
