摘要: 目的 探究孕激素受体膜组分1 (progesterone receptor membrane component 1, PGRMC1)与乳腺癌恶性增殖间的相关性。方法 纳入2017年9月至2019年1月本院乳腺外科收治的乳腺癌患者90例,年龄中位数为47岁,乳腺良性疾病患者60例,年龄中位数为45岁。患者均为女性,所有组织均在术前经空心针活检或经术后病理组织学检查确诊且自愿签署知情同意书。术后取病理组织,采用苏木精-伊红染色法判断乳腺癌组织病理分级,免疫组化法分别检测乳腺癌组织、乳腺良性疾病组织及乳腺良性疾病周围1 cm正常乳腺组织中雌激素受体(estrogen receptor, ER)、孕激素受体(progesterone receptor, PR)、人表皮生长因子受体2(human epidermal growth factor receptor 2, Her-2)、细胞增殖核抗原(nuclear-associated antigen, Ki-67)及PGRMC1的表达水平,分析PGRMC1与相关病理因素及与其他免疫指标的相关性。结果 乳腺癌组织中PGRMC1的阳性表达率为63.33%(57/90),乳腺良性疾病组织中的阳性表达率为28.33%(17/60),正常对照组织中PGRMC1阳性表达率仅为6.67%(4/60)。肿瘤直径大、有淋巴结转移、组织学分级高的乳腺癌患者,PGRMC1阳性表达率升高,组间比较差异有统计学意义(P<0.05),而与患者的月经情况无关(P>0.05)。乳腺癌组织中PGRMC1表达与ER、Ki-67、PR、Her-2的表达均有关系(P<0.05),其中与ER的关系最为密切(r=0.461),其次是Ki-67(r=0.330),而与PR、Her-2表达的关系较弱(分别为r=0.132,r=0.103)。乳腺良性疾病组织中PGRMC1表达与Ki-67及Her-2表达有关(P<0.05),其中与Ki-67(r=0.569)表达相关程度大于Her-2(r=0.228)表达。结论 PGRMC1在乳腺癌组织中高表达,并与乳腺癌淋巴结转移、肿瘤大小及组织学分级相关,可能在与激素相关肿瘤的恶性增殖及预后中有重要的临床意义,同时发现乳腺癌组织中PGRMC1与ER表达密切相关,这也进一步提示高表达PGRMC1促乳腺癌细胞增殖可能与调控ER信号通路相关。

Abstract: Objective To explore the correlation between progesterone receptor membrane component 1 (PGRMC1) and malignant proliferation of breast cancer. Methods The expression of PGRMC1 was detected immunohistochemically in 90 specimens of breast cancer (the median age was 47), 60 benign breast diseases (the median age was 45) and 60 cases of normal breast tissues from September 2017 to January 2019. All of them were women, and all tissues were diagnosed by the hollow needle biopsy or postoperative histologic examination. As a research project, all participants signed informed consent voluntarily.The pathological grade of breast cancer was determined viahematoxylin-eosin staining to determine. The association of PGRMC1 with pathological factors and the expression of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (Her-2), nuclear-associated antigen (Ki-67) was assessed. Results Positive expression of PGRMC1 was 63.33% (57/90) in breast cancer, 28.33% (17/60) in benign breast diseases and 6.67% (4/60) in normal breast tissues. PGRMC1 expression was significantly correlated to tumor size, lymphatic metastasis and the histological grade (P<0.001, respectively), PGRMC1 positive expression rate increased with the increase of histological grade of breast cancer, but not significantly correlated with menstruation in breast cancer (P>0.05). The expression of PGRMC1 in breast cancer group was related to the expression of ER, Ki-67, PR and Her-2 (P<0.05), which was most closely related to ER (r=0.461), followed by Ki-67 (r=0.330), but weakly correlated with the expression of PR and Ki-67(r=0.132,r=0.103, respectively). The expression of PGRMC1 in benign breast disease group was related to the expression of Ki-67 and Her-2 (P<0.05), and the correlation with the expression of Ki-67 (r=0.569) was higher than that of Her-2 (r=0.228). Conclusion PGRMC1 is highly expressed in breast cancer. PGRMC1 expression is strongly associated with the biological behavior of breast cancer. It may serve as a useful prognostic indicator of the malignancy. Meanwhile, it is found that PGRMC1 is closely related to ER expression in breast cancer, suggesting that PGRMC1 may potentiate estrogen signaling.
