The evaluation of ultrasound-guided core biopsy in detection of abnormal cervical lymph nodes

Tóm tắt

Objective: To assess the value of routine ultrasound (US) imaging and histopathological results of ultrasound-guided core needle biopsy (US-CNB) of abnormal cervical lymphadenopathy. Subject and method: From September 2022 to August 2023, a total 112 patients with clinical suspected cervical lymph nodes (CLNs) and/or have suspected signs on US (width ≥ 5mm, round in shape and absent hilus of CLNs) underwent US-CNB at 108 Military Central Hospital. Result: Among 112 patients, there were 56 metastatic lymph nodes, 10 lymphomas, 10 tuberculous and 32 nonspecific inflammatory lymph nodes. Level IV nodes included benign and malignant lesions was predominant. In the group of malignant CLNs: Irregular margin, absence of hilum and hypoechogenicity were found in 65.7%, 70% and 94.3% respectively, these proportions were significantly greater than that of benign group, with p<0.05. Comparison of US and histopathology of CLNs diagnosis: The sensitivity, specificity, positive predictive value, negative predictive value were 88.6%, 66.7%, 81.6%, 77.8%, respectively, when there were ≥ 2 suspected signs. Conclusion: Ultrasound is often considered as the first imaging diagnostic and valuable tool for detecting suspicious CLNs due to its convenience, non-invasiveness and cost-effectiveness, to helps reduce unnecessary interventions for benign lymph nodes. US-CNB is a minimally invasive technique that allows accurate diagnosis of the lymph node's histopathology.
