Clinical application of ultrasound-guided Core Needle Biopsy Histology and Fine Needle Aspiration Cytology in Cervical Lymph Nodes.

Objectives: To investigate the difference of application of core needle biopsy histology and fine needle aspiration cytology in cervical lymphadenopathy. Methods: A retrospective analysis was made on 80 patients with cervical lymphadenopathy admitted to Baoding No.1 Central Hospital from to October 2018 to February 2020, and they were randomly divided into two groups: core needle group and fine needle group. Patients in the core needle group were given core needle biopsy histology, while those in the fine needle group were given fine needle aspiration cytology, and the puncture results and surgical complications were compared between the two groups. Results: The accuracy rates of the core needle group and the fine needle group in the diagnosis of malignant cervical lymph nodes were 95.83% and 72.22% respectively, with a statistically significant difference (χ²=4.683, p=0.030). The sensitivity, specificity, positive predictive value and negative predictive value of the core needle group were 100.00%, 93.75%, 95.83% and 100.00% respectively, while those of the fine needle group were 86.67%, 90.00%, 86.67% and 90.00% respectively, with no statistically significant differences between the two groups (p>0.05). The complication rate in the core needle group was 22.50%, which was higher than the 5.00% in the fine needle group (χ²=5.165, p=0.023). Conclusions: No significant difference was observed between core needle biopsy histology and fine needle aspiration cytology in diagnosing cervical lymphadenopathy, but the former has a high complication rate.
