摘要:

目的 分析雄激素受体(androgen receptor,AR)、早期生长反应基因1(early growth response gene-1,EGR1)在三阴性乳腺癌中的表达情况,探讨二者与三阴性乳腺癌临床特征和预后的关系。方法 选取陕西省肿瘤医院2022年3月至2024年3月收治的100例三阴性乳腺癌患者为研究组,年龄(48.21±7.52)岁,病程(16.12±3.21)个月;选取同期100例非三阴性乳腺癌患者为参照组,年龄(47.54±5.68)岁,病程(16.32±3.24)个月。采用免疫组织化学法检测AR和EGR1表达情况,对比参照组、癌组织和癌旁组织AR、EGR1阳性表达率。分析癌组织中AR、EGR1表达与病理特征的相关性。将三阴性乳腺癌患者根据预后分成存活组和死亡组,对比两组AR和EGR1表达情况。统计学方法采用独立样本t检验、χ2检验和多元线性回归分析。结果 癌组织AR阳性表达率为22.00%(22/100),EGR1高表达率为21.00%(21/100),低于参照组的52.00%(52/100)与45.00%(45/100)和癌旁组织的78.00%(78/100)与78.00%(78/100),差异均有统计学意义(χ2=62.838、52.415,均P<0.05)。浸润性导管癌、Ⅰ~Ⅱ级患者、Ki-67指数<14%的三阴性乳腺癌患者AR阳性表达率分别为29.17%(21/72)、27.94%(19/68)和45.95%(17/37),组间对比,差异均有统计学意(χ2=7.696、4.371、19.625,均P<0.05)。肿瘤长径<3 cm、Ⅰ~Ⅱ级患者、Ⅰ~Ⅱ期患者、无淋巴结转移、Ki-67指数<14%的三阴性乳腺癌患者EGR1高表达率分别为42.22%(19/45)、27.94%(19/68)、27.69%(18/65)、40.74%(11/27)、48.65%(18/37),组间对比,差异均有统计学意义(χ2=22.212、6.171、5.014、6.573、27.062,均P<0.05)。存活组AR阳性表达率为43.18%(19/44),EGR1高表达率为45.45%(20/44),均高于死亡组(χ2=20.543、28.323,均P<0.05)。结论 三阴性乳腺癌患者AR、ERG-1异常表达,与疾病病理分期和Ki-67等病理特征密切相关,且对患者预后有显著影响。

Abstract:

Objective To analyze the expressions of androgen receptor (AR) and early growth response gene-1 (EGR1) in triple-negative breast cancer, and to explore their relationship with the clinical features and prognosis. Methods One hundred patients with triple-negative breast cancer treated at Shaanxi Provincial Cancer Hospital from March 2022 to March 2024 were selected as a study group; they were (48.21±7.52) years old; their disease course was (16.12±3.21) months. One hundred patients with non-triple-negative breast cancer during the same period were selected as a reference group; they were (47.54±5.68) years old; their disease course was (16.32±3.24) months. Immunohistochemistry was used to detect the AR and EGR1 expressions. The positive expression rates of AR and EGR1 in the reference group, carcinoma tissue, and adjacent tissue were compared. The correlation of AR and EGR1 expressions in the cancer tissue with the pathological characteristics was also analyzed. The patients with triple-negative breast cancer were divided into a survival group and a death group according to their prognosis, and the AR and EGR1 expressions were compared between the two groups. The statistical methods included the independent sample t test, χ2 test, and multiple linear regression analysis. Results The positive expression rate of AR and the high expression rate of EGR1 in the cancer tissue were 22.00% (22/100) and 21.00% (21/100), which were lower than those in the reference group [52.00% (52/100) and 45.00% (45/100)] and those in the adjacent tissue [78.00% (78/100) and 78.00% (78/100)], with statistical differences (χ2=62.838 and 52.415; both P<0.05). The AR positive expression rates of the triple-negative breast cancer patients with invasive ductal carcinoma, grade Ⅰ-Ⅱ, and Ki-67 index <14% were 29.17% (21/72), 27.94% (19/68), and 45.95% (17/37), respectively; there were statistical differences between the groups (χ2=7.696, 4.371, and 19.625; all P<0.05). The high expression rates of EGR1 in the patients with tumor diameter <3 cm, grade Ⅰ-Ⅱ, stage Ⅰ-Ⅱ, no lymph node metastasis, and Ki-67 index <14% were 42.22% (19/45), 27.94% (19/68), 27.69% (18/65), 40.74% (11/27), and 48.65% (18/37), respectively; there were statistical differences between the groups (χ2=22.212, 6.171, 5.014, 6.573, and 27.062; all P<0.05). The positive expression rate of AR and the high expression rate of EGR1 in the survival group were 43.18% (19/44) and 45.45% (20/44), which were higher than those in the death group (χ2=20.543 and 28.323; both P<0.05). Conclusion The abnormal expressions of AR and ERG1 in patients with triple-negative breast cancer are closely related to the pathological stage and pathological features such as Ki-67, and have significant impact on their prognosis.
