彩色多普勒超声检查对卵巢癌淋巴结转移的诊断价值

Diagnostic value of color Doppler ultrasound examination in lymph node metastasis of ovarian cancer

目的探讨彩色多普勒超声检查对卵巢癌淋巴结转移的诊断价值。方法选取98例卵巢癌患者,术前均接受彩色多普勒超声检查。以病理检查结果为金标准,比较淋巴结转移与未转移患者的血流分级和彩色多普勒超声检查影像特征,评估彩色多普勒超声检查对卵巢癌患者淋巴结转移的诊断效能。结果病理检查结果显示,98例卵巢癌患者中,淋巴结转移56例,淋巴结未转移42例。与淋巴结未转移患者比较,淋巴结转移卵巢癌患者的血流信号更丰富,差异有统计学意义(P<0.05)。淋巴结转移卵巢癌患者圆形结节、有中心坏死、有包膜侵犯比例均明显高于淋巴结未转移患者,结节大小明显大于淋巴结未转移患者,差异均有统计学意义(P<0.01)。彩色多普勒超声检查诊断卵巢癌患者淋巴结转移的灵敏度为96.43%,特异度为97.62%,准确度为96.94%,阳性预测值为98.18%,阴性预测值为95.35%。结论彩色多普勒超声检查对卵巢癌患者淋巴结转移情况有一定的诊断价值,能清晰地显示病灶血流状况。

Objective To explore the diagnostic value of color Doppler ultrasound examination in lymph node metastasis of ovarian cancer.Method A total of 98 patients with ovarian cancer were selected and underwent preoperative color Doppler ultrasound examination.Using pathological examination results as the gold standard,the blood flow grading and color Doppler ultrasound examination imaging characteristics were compared between the ovarian patients with lymph node metastasis and without lymph node metastasis,and the diagnostic value of color Doppler ultrasound examination for lymph node metastasis in ovarian cancer patients were evaluated.Result The pathological examination results showed that,among 98 ovarian cancer patients,56 cases had lymph node metastasis and 42 cases without lymph node metastasis.Compared to patients without lymph node metastasis,ovarian cancer patients with lymph node metastasis had richer blood flow signals,and the difference was statistically significant(P<0.05).The proportion of round nodules,central necrosis,and capsule invasion in ovarian cancer patients with lymph node metastasis were significantly higher than those in patients without lymph node metastasis,and the size of the nodule was significantly larger than that in patients without lymph node metastasis,and the differences were statistically significant(P<0.01).The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of color Doppler ultrasound examination in diagnosing lymph node metastasis in ovarian cancer patients were 96.43%,97.62%,96.94%,98.18%,and 95.35%,respectively.Conclusion Color Doppler ultrasound examination has a certain diagnostic value for lymph node metastasis in ovarian cancer patients,which can clearly display the blood flow status of the lesion.
