乳腺癌内分泌治疗的临床疗效与癌组织ERβ表达的相关因素分析

[摘要] 目的 通过对乳腺癌患者癌组织中雌激素受体β表达情况的检测,探讨乳腺癌内分泌治疗的临床疗效与癌组织ERβ表达的相关因素。方法 以2014年1月―2016年6月到期间于该院就诊的临床资料完整、绝经女性84例,经过病理学确诊为乳腺癌患者,术后口服他莫昔芬进行内分泌治疗。通过免疫组化发,对ERβ阳性表达情况进行检测。 结果 84例患者中,ERβ阳性表达52例,表达率为61.90%。ERβ阳性表达患者,与患者年龄、肿瘤大小、TNM分期、是否进行放疗及化疗等因素无关,组间分析差异无统计学意义(P>0.05)。ERβ阳性表达患者,进行内分泌治疗者,3年生存率与5年生存率显著大于未接受内分泌治疗者,差异有统计学意义(P0.05)。有效随访结果显示,ERβ阴性患者,无瘤生存时间为(78.6±10.2)个月,ERβ阳性患者,中位无瘤生存时间为(60.9±12.5)个月。结论 乳腺癌的发生过程与ERβ表达存在密切关联,乳腺癌内分泌治疗的临床疗效与癌组织中ERβ表达存在相关性。

[Abstract] Objective To discuss the clinical curative effect of breast cancer endocrinotherapy and analysis of correlative factor with cancer tissue ERβ expression. Methods 84 cases of menopause women with breast cancer diagnosed in our hospital from January 2014 to June 2016 were selected and took the tamoxifen orally for endocrinotherapy, and the ERβ expression positive expression situation was tested by the immunohistochemical method. Results Of 84 cases, there were 52 cases with ERβ positive expression, and the expression rate was 61.90%, and the patients with ERβ positive expression was not related to the age, tumor size, TNM stage and whether to receive the radiotherapy and chemotherapy, and the differences between the two groups were statistically significant(P>0.05), and the 3-year survival rate and 5-year survival rate were obviously higher than patients without endocrinotherapy, and the differences were statistically significant,(P0.05), and the effective follow-up results showed that the tumor-free survival time of ERβ negative patients was(78.6±10.2) months, and the median tumor-free survival time of ERβ positive patients was(60.9±12.5) months. Conclusion The occurrence course of breast cancer is closely correlated with the ERβ expression, and the clinical curative effect of breast cancer endocrinotherapy has a correlation with the ERβ expression in cancer tissues.

乳腺癌是威胁现代女性生活质量和生命的严重恶性肿瘤之一,根据文献报道,全球乳腺癌患者逐年增长,死亡率逐年递增,且呈年轻化趋势[1]。手术切除是临床上治疗乳腺癌的主要方式,辅助的治疗手段为放疗及化疗,如有需要,进一步进行内分泌药物治疗[2]。

激素依赖性肿瘤,即体内多种激素的调控可影响癌细胞的生长[3]。其中,最具代表性的激素依赖性肿瘤即为乳腺癌,乳腺癌的发生发展主要是受雌激素的调控,而通过药物或其他方式,降低或抑制体内雌激素的水平,进而可以达到治疗内分泌的目的,最后抑制肿瘤的生长[4]。而雌激素受体α、β(estrogen receptor α、β,ERα,ERβ)是检验内分泌治疗是否有效的重要因素[5]。1986年法国学者Chambon首次成功克隆出雌激素受体的cDNA,发现ERα,ERβ后,两者即成为中外乳腺癌研究者、医者重点探讨研究的对象,由于ERα发现较早,学者对此研究校对,而ERβ的研究相对较少。该研究以2014年1月―2016年6月期间,采用免疫组化法对乳腺癌患者肿瘤组织中ERβ表达情况进行检测,重点探讨乳腺癌内分泌治疗的临床疗效与癌组织ERβ表达的相关性,现报道如下。
