摘要

目的：

探讨弥散加权成像（diffusion-weighted imaging，DWI）不同参数术前评估子宫内膜癌淋巴脉管间隙浸润（lymphovascular space invasion，LVSI）的价值。

方法：

回顾并分析146例子宫内膜癌患者的临床及病理学资料，其中LVSI（-）组109例，LVSI（+）组37例。测量两组患者表观弥散系数最大值（maximum apparent diffusion coefficient，ADC

max

）、ADC最小值（ADC

min

）、ADC平均值（ADC

mean

）这3个参数，比较两组间各参数的差异，采用受试者工作特征（receiver operating characteristic，ROC）曲线比较ADC min 及ADC mean 鉴别子宫内膜癌LVSI的诊断效能。

结果：

两组患者ADC

max

差异无统计学意义（

＞0.05），两组间ADC

mean

（

=13.832，

＜0.001）及ADC

min

（

=19.927，

＜0.001）差异有统计学意义。ADC

min

、ADC

预测子宫内膜癌LVSI的ROC曲线的曲线下面积分别为0.853、0.772。根据最佳诊断阈值，ADC

min

及ADC

mean

评估子宫内膜癌LVSI的灵敏度分别为86.5%及62.2%，特异度为71.6%及82.6%。ADC

评估LVSI的诊断效能明显高于ADC

mean

（

=0.026）。

结论：

ADC

均有助于术前评估子宫内膜癌LVSI，且ADC

的诊断效能更高。

Abstract

Objective:

To investigate the value of diffusion-w

eighted imaging (DWI) with different parameters in preoperative evaluation of lymphovascular space invasion (LVSI) of endometrial carcinoma (EC).

Methods:

The clinical and pathological data of 146 cases of EC were retrospectively analyzed

including 109 cases of LVSI (-) and 37 cases of LVSI (+). Maximum apparent diffusion coefficient (ADC max )

ADC

min

and ADC

mean

of the two groups of patients were measured

and the differences of each parameter between the two groups were compared. Receiver operating characteristic (ROC) curve analysis was carried out to evaluate the diagnostic performance of ADC

min

and ADC

mean

in evaluating LVSI status in EC.

Results:

No statistically significant difference was found in ADC

max

between the two groups (

＞0.05).There was significant difference in ADC

mean

(

=13.832

＜0.001) and ADC

min

(

=19.927

＜0.001) between the two groups. The area under curve (AUC) of ADC

min

ADC

mean

for evaluating LVSI status in EC were 0.853 and 0.772 respectively. According to the optimal cut point

the sensitivity and specificity value of ADC

min

and ADC

mean

were 86.5% and 62.2%

71.6% and 82.6%. The diagnostic performance of LVSI evaluated by ADC min was significantly higher than ADC

mean

(

=2.221

=0.026).

Conclusion:

Both ADC

min

and ADC

mean

are helpful for preoperative evaluation of LVSI status in EC

and ADC

min

has a higher diagnostic performance.
