摘要：

目的：探讨乳腺癌患者癌组织中SIRT3表达与临床特征和预后之间的相关性。方法：回顾性收集南通大学附属医院2010年1月至2015年6月250例经病理检查证实为乳腺癌女性患者的临床资料，运用免疫组化法检测癌组织中SIRT3的表达水平，并分析其与患者临床、病理资料和总生存期的关系。结果：肿瘤≥2 cm，淋巴结转移，组织学Ⅱ级、Ⅲ级，小叶癌，PR受体阴性，Her2受体阴性情况下SIRT3呈现高表达比例均较高，差异有统计学意义（均P<0.05）。多因素Cox回归分析显示，肿瘤大小、淋巴结转移以及SIRT3表达是影响总生存时间的独立影响因素。SIRT3低表达组中位生存时间为43个月（95%CI为41.24~44.75），SIRT3高表达组中位生存时间为29个月（95%CI为28.83~31.17），两组差异有统计学意义（P=0.005）。结论：SIRT3蛋白可作为一个评价乳腺癌患者预后的重要指标及潜在治疗靶标。

Objective:To investigate the correlation between SIRT3 expression and clinical features and prognosis in patients with breast cancer. Methods:The clinical data of 250 female patients with breast cancer were collected and analyzed retrospectively from January 2010 to June 2015. The expression of SIRT3 in tumor tissues was detected using immunohistochemical method, and the relationship between the clinical data and the overall survival of patients was analyzed. Results:Tumors whose size larger than 2 cm with lymph node metastasis, histological grade Ⅱ and Ⅲ, lobular carcinoma and negative PR receptors were associated with the high expression level of SIRT3 with a significant difference(P<0.05). Multiple Cox regression analysis showed that age, menstruation, lymph node metastasis and SIRT3 expression were independent factors affecting overall overall survival. The median survival time was 43 months (95%CI:41.24-44.75) in the SIRT3 low expression group, and 29 months (95%CI:28.83-31.17) in the SIRT3 high expression group, with a statistically significant difference (P=0.005). Conclusion:SIRT3 protein can be used as an important index and potential therapeutic target in the diagnosis and evaluating prognosis of breast cancer patients.
