Abstract

Abstract: Objective To investigate the expression of aldehyde dehydrogenase 1 （ALDH1） in sentinel lymph nodes of breast cancer and its clinical significance. Methods The clinical data of patients who underwent breast cancer surgery in Maoming People′s Hospital between May 2021 and May 2022 were collected. The expression of ALDH1 in sentinel lymph nodes with metastasis （n = 26） and without metastasis n = 29） of breast cancer was detected by immunohistochemical staining. Results The positive expression rate of ALDH1 in breast cancer metastatic sentinel lymph nodes and non metastatic sentinel lymph nodes was 76.9% （20/26） and 17.2% （5/29）, respectively. The positive expression rate of ALDH1 in metastatic sentinel lymph nodes was significantly higher than that in non metastatic sentinel lymph nodes （P<0.01）. It was found that there was no statistical significance between the expression of ALDH1 in sentinel lymph nodes with histological grading, clinical stage, tumor diameter, expression of estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, Ki-67 and molecular types （P>0.05）, but it was related to patient′s age （P<0.05）, the difference between the expression of ALDH1 and axillary lymph node metastasis, as well as the accuracy of sentinel lymph nodes with clear pathological characteristics after surgery, was statistically significant （P<0.01）. Conclusion The expression of ALDH1 in sentinel lymph nodes of breast cancer is not related to clinical stage, tumor diameter, histological grade, ER, PR, HER-2, Ki-67 and molecular types, but related to the patient′s age, axillary lymph node metastasis and postoperative pathological state of sentinel lymph node.

摘要： 目的探讨乙醛脱氢酶1（ALDH1）在乳腺癌前哨淋巴结中的表达及其临床意义。方法收集2021年05月至2022年05月在茂名市人民医院行乳腺癌手术患者的临床资料,釆用免疫组织化学染色法检测乳腺癌转移的前哨淋巴结（n=26）和未转移的前哨淋巴结（n=29）中ALDH1的表达情况,分析前哨淋巴结中 ALDH1 的表达情况与原发灶临床病理特征及预后指标之间的关系。结果乳腺癌转移前哨淋巴结和未转移前哨淋巴结中 ALDH1 阳性表达率分别为76.9%（20/26）、17.2%（5/29）,转移前哨淋巴结中 ALDH1 阳性表达率显著高于未转移前哨淋巴结（P< 0.01）。将乳腺癌前哨淋巴结中 ALDH1 的表达情况与原发灶的组织学分级、临床分期、肿瘤直径、雌激素受体、孕激素受体、人类表皮生长因子受体2、Ki-67的表达情况及分子分型进行差异性分析,显示均无统计学意义（P>0.05）,但与患者的年龄有关（P<0.05）;将ALDH1的表达情况与腋窝淋巴结转移情况以及与术后病理明确性质的前哨淋巴结的准确性进行差异性分析,显示具有统计学意义（P<0.01）。结论乳腺癌前哨淋巴结中 ALDH1 表达情况与肿瘤临床分期、肿瘤直径、组织学分级、ER、PR、HER-2、Ki-67、分子分型等预后指标无关,与患者年龄、腋窝区域淋巴结转移情况及术后病理前哨淋巴结的良恶性有关。
