ABSTRACT
OBJECTIVE:
To explore the sonographic features of malignant hilar and mediastinal lymph nodes and the predictive value.METHODS:
We performed retrospective analysis of 390 lymph nodes under the endobronchial ultrasound-guided transbronchial needle aspiration for diagnosis in the bronchoscope center of the First Affiliated Hospital of Guangzhou Medical University from November 1st, 2012 to November 31st, 2013. They were divided into malignant and benign groups, and sonographic features of lymph nodes were analyzed, including the length of short axis, shape, margin, echogenicity, homogenicity, coagulation necrosis, calcification, coalesence and posterior acoustic enhancement.RESULTS:
A total of 390 lymph nodes were evaluated, including 207 malignant and 183 benign lymph nodes, respectively. The accuracy based on the length of short axis, shape, margin, echogenicity, homogenicity, coagulation necrosis, calcification, coalesence and posterior acoustic enhancement to predict the malignancy were 61.0% (238/390), 75.4% (294/390), 75.6% (295/390), 73.8% (288/390), 65.9% (257/390), 68.2% (266/390), 51.8% (202/390), 55.1% (215/390), 67.4% (263/390), respectively. Binary multivariable logistic regression analysis revealed that 5 parameters, including round, distinct margin and heterogeneous, hypoechoic, and posterior acoustic enhancement possessed a significant predictive value(P < 0.05).We found that only 35.3% (73/207) malignant lymph nodes possessed these 5 ultrasonographic characteristics, and the diagnosis rate was 93.6% (73/78).72.46% (150/207) malignant lymph nodes possessed any 4 or more positive sonographic features, and the diagnosis rate was 85.2% (150/176).85.0% (176/207) malignant lymph nodes had any 3 or more positive sonographic features, and the diagnosis rate was 84.6% (176/208).CONCLUSION:
The combination of gray scale sonographic features has a predictive value in the diagnosis of malignant hilar and mediastinal lymph nodes.
