先前的研究表明膜联蛋白 A1 (AnxA1) 和膜联蛋白 A2 (AnxA2) 与三阴性乳腺癌 (TNBC) 的侵袭行为相关。我们的目的是确定 AnxA1 和 AnxA2 与 TNBC 患者不良预后的相关性。我们分析了微阵列数据集中人类膜联蛋白家族的基因表达,并将其与临床结果相关联,以确定其预测预后的能力。在我们的 TNBC 队列中,平均随访时间为 57.2 个月,AnxA1 高表达是总生存期 (OS) 较差的独立指标[风险比 (HR),2.14; 95% 置信区间 (CI),1.22-3.78] 和无复发生存 (RFS) 预后 [HR,1.66; 95% CI,1.28-2.17]。此外,AnxA2 高表达是 OS 较差的独立指标 [HR,2.66; 95% CI,1.14-6.25],RFS [HR,1.45; 95% CI,1.12-1.89],RFS [HR,1.45; 95% CI,1.12-1.89) 和无远处转移生存 (DMFS) 预后 [HR,1.5; 95% CI,1.16-1.95]。对 AnxA1 和 AnxA2 高水平的 TNBC 患者的分析表明,与独立基因表达相比,OS (P=0.0017) 和 RFS (P=0.0002) 显着降低。此外,AnxA1 的预后影响依赖于 AnxA2 的高表达,与其他乳腺癌亚型相比,两者都优先用于 TNBC。这些发现共同表明 AnxA1 和 AnxA2 是 TNBC 患者中优先的双重预后预测因子。
Previous studies have shown Annexin A1 (AnxA1) and Annexin A2 (AnxA2) association with the aggressive behavior of Triple Negative Breast Cancer (TNBC). Our aim was to determine the correlation of AnxA1 and AnxA2 with poor prognosis of TNBC patients. We analyzed the gene expression of the human annexin family from microarray datasets and correlated with clinical outcomes to determine their ability to predict prognosis. Within a mean follow-up time of 57.2 months in our TNBC cohort, high AnxA1 expression was an independent indicator of poor overall survival (OS) [hazard ratio (HR), 2.14; 95% confidence interval (CI), 1.22-3.78] and relapse-free survival (RFS) prognosis [HR, 1.66; 95% CI, 1.28-2.17]. Additionally, high AnxA2 expression was an independent indicator of poor OS [HR, 2.66; 95% CI, 1.14-6.25], RFS [HR, 1.45; 95% CI, 1.12-1.89], RFS [HR, 1.45; 95% CI, 1.12-1.89), and distant metastasis free survival (DMFS) prognosis [HR, 1.5; 95% CI, 1.16-1.95]. Analyses of TNBC patients with both high AnxA1 and AnxA2, demonstrates a significant decrease in OS (P=0.0017) and RFS (P=0.0002) when compared to the expression of genes independently. Furthermore, AnxA1 prognostic impact relies on high AnxA2 expression and both are preferential for TNBC when compared to other breast cancer subtypes. Together these findings indicate that AnxA1 and AnxA2 are preferential dual prognostic predictors among TNBC patients.
