摘要

目的：

评价穿刺针数对超声引导下甲状腺细针抽吸细胞学检查（ultrasound-guided fine-needle aspiration cytology，US-FNAC）诊断效能的影响。

方法：

收集2015年6月2018年6月于南京医科大学附属南京医院（南京市第一医院）行US-FNAC并经手术治疗的甲状腺结节患者352例，共352个结节，每个结节穿刺4针，病理科医师在穿刺现场依据甲状腺细胞病理学Bethesda报告系统（The Bethesda System for Reporting Thyroid Cytopathology，TBSRTC）进行细胞学诊断。按照总的穿刺针数分为A组（第1针）、B组（前2针）、C组（前3针）、D组（前4针）4组，将所有结节的细胞学穿刺结果与术后组织病理学检查结果比较，分为符合和不符合两类，分别计算灵敏度、特异度和准确度。

结果：

A、B、C、D4组的灵敏度分别为70.8%、85.6%、94.2%、97.8%，特异度分为别55.0%、75.0%、100.0%、100.0%，准确度分别为69.0%、84.4%、94.9%、98.0%，差异均有统计学意义（

＜0.001）；组间比较，A、B、C组间两两比较各项统计指标差异均有统计学意义（

＜0.008）；C、D两组间差异无统计学意义（

＞0.008）。

结论：

穿刺灵敏度、特异度及准确度随针数增加而增加，但综合考虑，3针在未出现并发症的基础上穿刺效能最高，可作为常规推荐。

Abstract

Objective:

To evaluate the effect on the number of aspirates on the diagnostic efficacy of ultrasound-guided fine-needle aspiration cytology (US-FNAC) in thyroid nodules.

Methods:

From June 2015 to June 2018

352 patients were operated US-FNAC and thyroidectomy. Each nodule was aspirated 4 times. Cy

topathologist diagnosed specimen based on The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) on-site. According to the total numbers of aspiration

cytological results were divided into four groups: group A (1st needle)

group B (first 2 needles)

group C (first 3 needles)

and group D (total 4 needles). Yields of US-FNAC were divided into two levels of accuracy and inaccuracy according to the pathological results of paraffin and diagnostic accuracy was calculated separately.

Results:

The sensitivity of group A

D were 70.8%

85.6%

94.2%

97.8%. The specificity of group A

D were 55.0%

75.0%

100.0%

100.0%. The accuracy of group A

D were 69.0%

84.4%

94.9%

98.0%

respectively. The sensitivity

specificity and accuracy of four groups showed statistically significant difference (

＜0.001). There were statistically significant differences in 3 parameters between group A

group B and group C (P＜0.008). Group C and D showed no statistically significance (

＞0.008).

Conclusion:

The sensitivity

specificity

and accuracy of aspiration increase with the number of needles. However

comprehensively considered

the 3 needles have the highest efficiency of aspiration on the basis of no complications

and can be used as a routine recommendation.
