UNASSIGNED: A retrospective analysis was conducted on patients who underwent FNA between May 2018 and May 2021 at our hospital. Cytological, histopathological, and clinical follow-up data were analyzed. The diagnostic yield of FNA was assessed based on sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy calculations.
UNASSIGNED: This study included 505 patients, each with a small cervical lymph node under evaluation (total number of lymph nodes: 505). The average maximal diameter of the lymph nodes was 14.6 ± 6.2 mm. According to the Sydney system, the cytology results were as follows: Category I in 26 lymph nodes (5.1 %); Category II in 269 (53.3 %); Category III in 35 (6.9 %); Category IV in 17 (3.4 %); and Category V in 158 (31.3 %). We identified 212 malignant cases (203 metastases and 9 lymphomas) and 293 benign lymph nodes. FNA achieved high sensitivity (88.8 %), specificity (99.6 %), PPV (99.4 %), NPV (91.8 %), and overall accuracy (94.8 %) in determining the etiology of small cervical lymph nodes.
UNASSIGNED: FNA cytology is suitable for small lesions inaccessible by CNB and provides a diagnostic basis for implementing clinically appropriate treatment measures.
■对2018年5月至2021年5月在我院接受FNA的患者进行了回顾性分析。细胞学,组织病理学,并对临床随访资料进行分析。根据灵敏度评估FNA的诊断率,特异性,阳性预测值(PPV),负预测值(NPV),和精确计算。
■这项研究包括505名患者,每个有一个小的颈部淋巴结评估(淋巴结总数:505)。淋巴结的平均最大直径为14.6±6.2mm。根据悉尼系统,细胞学结果如下:26个淋巴结中的I类(5.1%);269个中的II类(53.3%);35个中的III类(6.9%);17个中的IV类(3.4%);158个中的V类(31.3%).我们确定了212例恶性病例(203例转移和9例淋巴瘤)和293例良性淋巴结。FNA实现了高灵敏度(88.8%),特异性(99.6%),PPV(99.4%),净现值(91.8%),以及确定颈部小淋巴结病因的总体准确性(94.8%)。
■FNA细胞学检查适用于CNB无法进入的小病灶,为实施临床上适当的治疗措施提供了诊断依据。
