摘要:
目的探讨子宫内膜癌组织中DAPK3和c-Myc的表达情况、相互关系及其对患者预后的影响。方法运用免疫组织化学 SP法检测132例子宫内膜癌组织中DAPK3和c-Myc的表达,分析DAPK3、c-Myc蛋白的表达与子宫内膜癌临床病理参数的关 系及对子宫内膜癌预后的影响。结果(1)132例组织标本中DAPK3低表达80例(80/132,60.61%),c-Myc高表达71例(71/132, 53.79%);(2)DAPK3的表达在子宫内膜癌不同FIGO分级(P=0.034),组织学分级(P=0.027),淋巴结转移状态(P=0.022)和肌层 浸润程度(P=0.011)中差异显著;c-Myc的表达在子宫内膜癌不同FIGO分级(P=0.015)和淋巴结转移状态(P=0.031)中差异显 著;(3)生存曲线分析显示,DAPK3低表达患者的生存时间少于高表达患者(P=0.023),而c-Myc高表达患者的生存时间少于低 表达患者(P=0.002);(4)等级相关分析显示DAPK3和c-Myc在子宫内膜癌中的表达显著负相关(r=-0.310, P<0.001);(5)COX 回归分析提示,c-Myc高表达是子宫内膜癌患者预后的独立影响因素(P=0.007)。结论DAPK3低表达和c-Myc高表达与子宫 内膜癌的生长浸润行为相关,且与患者预后密切相关。通过检测DAPK3和c-Myc的表达能够更加有效地评估子宫内膜癌患者 的预后。
Abstract:
Objective To investigate the expressions of DAPK3 and c-Myc and their prognostic value in endometrial carcinoma (EC). Methods The expressions of DAPK3 and c-Myc were detected immunohistochemically in 132 surgical specimens. The relationship between DAPK3 and c-Myc protein expressions and the clinicopathological features of the patients was evaluated. Results Immunohistochemical analysis revealed low DAPK3 expression in 60.61% (80/132) and high c-Myc expression in 53.79% (71/132) of the specimens of EC. Both DAPK3 expression and c-Myc expression were significantly correlated with FIGO stage (P=0.034 and 0.015, respectively) and lymph node metastasis (P=0.022 and 0.031, respectively). DAPK3 expression was closely correlated with the histological grade (P=0.027) and depth of myometrial invasion (P=0.011). Kaplan-Meier survival analysis indicated that patients with low DAPK3 expressions had a shorter overall survival rate than those with high DAPK3 expressions (P=0.023), while patients with high c-Myc expressions had poorer prognoses than those with low c-Myc expressions (P=0.002). Spearman correlation analysis showed that DAPK3 and c-Myc expressions were negatively correlated (P<0.001, r=?0.310). Multivariate analysis identified a high c-Myc expression as the independent predictor of the prognosis of EC (P=0.007). Conclusions A low expression of DAPK3 and a high expression of c-Myc are associated with aggressive and metastatic behaviors of EC, and their detection may help to predict the prognosis of the EC patients.
