Abstract

OBJECTIVE

In this study, 345 patients with endometrial carcinoma (EC) were selected to investigate the correlation between ER/PR status and the EC disease-free survival (DFS) rate.

METHODS

The intensity and proportion of tumor cell expression of estrogen receptors and progesterone receptors (ER/PR) status of 345 postoperative tumor specimens in ECs were independently assessed semi-quantitatively by two pathologists using immunohistochemistry, the summed score ranged from 0 to 8 points was worked out by adding proportion score and intensity score based on the breast cancer hormone receptor immunohistochemical Allred scoring system. The association between DFS in ECs and ER/PR expression (intensity, proportion and summed score) was assessed using Cox regression analysis. Gene expression data were obtained from The Cancer Genome Atlas research network (TCGA).

RESULTS

According to inclusion criteria, 201 type I and 144 type II EC patients were enrolled in this study. In the univariate analysis of type I endometrial carcinoma, the intensity, proportion and summed score of ER/PR status were significantly correlated with DFS. After adjusting for factors known to significantly impact survival, the influence of ER/PR status on DFS is generally decreased but the correlation is still significant. In the univariate analysis of type II endometrial carcinoma, the intensity, proportion and summed score of ER/PR status were significantly correlated with DFS. After adjusting for factors known to significantly impact survival, the influence of ER status on DFS is generally decreased, but the correlation is still significant, the effect of PR expression on DFS is not statistically significant.

CONCLUSION

Higher ER/PR expression status was associated with better DFS in patients with type I endometrial cancer after adjusting for known factors that significantly affect survival. In patients with type II endometrial cancer, patients with positive ER expression were significantly associated with better DFS. However, the effect of PR expression on DFS was not statistically significant.

摘要

目的

本研究选取345例子宫内膜癌(EC)患者,探讨雌激素受体/孕激素受体(ER/PR)状态与EC无病生存率(DFS)之间的相关性。

方法

两名病理学家采用免疫组织化学方法对345例EC术后肿瘤标本中肿瘤细胞雌激素受体和孕激素受体(ER/PR)状态的表达强度和比例进行独立半定量评估,根据乳腺癌激素受体免疫组织化学奥尔雷德评分系统,将比例评分与强度评分相加得出总分,范围为0至8分。采用Cox回归分析评估EC患者DFS与ER/PR表达(强度、比例和总分)之间的关联。基因表达数据来自癌症基因组图谱研究网络(TCGA)。

结果

根据纳入标准,本研究纳入201例I型和144例II型EC患者。在I型子宫内膜癌的单因素分析中,ER/PR状态的强度、比例和总分与DFS显著相关。在对已知显著影响生存的因素进行调整后,ER/PR状态对DFS的影响总体上有所降低,但相关性仍然显著。在II型子宫内膜癌的单因素分析中,ER/PR状态的强度、比例和总分与DFS显著相关。在对已知显著影响生存的因素进行调整后,ER状态对DFS的影响总体上有所降低,但相关性仍然显著,PR表达对DFS的影响无统计学意义。

结论

在对已知显著影响生存的因素进行调整后,I型子宫内膜癌患者中较高的ER/PR表达状态与较好的DFS相关。在II型子宫内膜癌患者中,ER表达阳性的患者与较好的DFS显著相关。然而,PR表达对DFS的影响无统计学意义。
