阴道超声对卵巢癌淋巴结转移的定性分析

Qualitative Analysis of Lymph Node Metastasis in Ovarian Cancer by Transvaginal Ultrasound

目的探讨阴道超声对卵巢癌淋巴结转移的定性价值。方法回顾性研究,选择2017年2月到2018年4月在医院诊治的卵巢癌患者56例,所有患者都给予超声检查,记录超声特征与淋巴结转移状况,并进行病理学分析。结果超声判断为淋巴结转移38例,转移阳性率为67. 9%。淋巴结转移阳性患者的病灶形态、包膜外侵、中心有无坏死、病灶大小方面与淋巴结转移阴性患者有统计学差异(P <0. 05)。淋巴结转移阳性患者彩色多普勒超声血流分型Ⅰ型、Ⅱ型、Ⅲ型、Ⅳ型分别为30例、6例、2例与0例,淋巴结转移阴性患者分别为0例、2例、6例、10例,对比差异有统计学意义(P <0. 05)。手术病理判断为淋巴结转移阳性36例,阴性20例,经阴道超声对卵巢癌淋巴结转移诊断的敏感性与特异性分别为97. 2%和85. 0%。结论淋巴结转移在卵巢癌中较为常见,阴道超声可有效显示病灶特征与血流状况,对淋巴结转移诊断具有较好的敏感性和特异性。

Objective To evaluate the qualitative diagnostic value of transvaginal ultrasound in lymph node metastasis of ovarian cancer. Methods Retrospective study was used,56 cases of ovarian cancer patients were selected. All patients were given ultrasound examination,ultrasound features and lymph node metastasis status were recorded,and pathological analysis were conducted. Results In the 56 patients,there were 38 patients of lymph nodes metastases were diagnosed by ultrasound and the positive rate of metastasis was 67. 9%. The lesion morphology of the patients with lymph node metastasis were mostly round,multiple combined with outer capsule invasion,and central necrosis,and the size of the lesion were significantly higher than that of negative lymph node metastasis( n = 18)( P < 0. 05). The color Doppler ultrasound pattern were type Ⅰ,type Ⅱ,Ⅲ and Ⅳ were 30 cases,6 cases,2 cases and 0 case respectively in the patients with lymph node metastasis,and there were 0 case,2 cases,6 cases and 10 cases of the negative lymph node metastasis that compared were statistically significant( P < 0. 05). There were 36 cases of lymph node metastasis were positive and 20 cases were negative,the sensitivity and specificity of transvaginal ultrasound in the diagnosis of lymph node metastasis of ovarian cancer were 97. 2% and 85. 0%. Conclusion The lymph node metastasis is more common in ovarian cancer,the application of transvaginal ultrasound can effectively display the characteristics of the lesion and blood flow,and improve the sensitivity and specificity of the lymph node metastasis.
