[目的]探讨彩超引导下细针吸取细胞学检查对左锁骨上小淋巴结定性的临床应用价值。[方法]对228例经超声发现左锁骨上长径<1cm淋巴结的恶性肿瘤患者行超声引导下细针吸取行病理细胞学检查。[结果]228例左锁骨上小淋巴结患者中,经超声引导下FNAC检查证实为转移性肿瘤84例,转移性肿瘤检出率为36.84%。淋巴结L/T比值<2转移性肿瘤检出率约44.25%,L/T比值≥2转移性肿瘤检出率12.96%(χ2=17.340,P=0.000)。有血流信号的结节穿刺肿瘤检出率高于无血流信号者(60.61%vs32.82%,P<0.01)。[结论]彩超引导下细针吸取细胞学检查对左锁骨上<1cm淋巴结定性有一定鉴别价值,为临床治疗方案制定提供重要信息。
[Objective] To investigate the clinical value of fine needle aspiration cytology in the diagnosis of small lymph nodes on the left supraclavicular bone. [Method] 228 cases of malignant tumors of the left clavicle with lymph node> 1 cm in length were examined with ultrasonography guided fine needle aspiration cytological examination. [Results] Among 228 cases of left supraclavicular lymph nodes, FNAC was proved to be 84 cases of metastatic tumors under ultrasound guidance. The detection rate of metastatic tumors was 36.84%. Lymph node L / T ratio <2 metastatic tumor detection rate of about 44.25%, L / T ratio ≥ 2 metastatic tumor detection rate of 12.96% (χ2 = 17.340, P = 0.000). The detection rate of nodules with blood flow signal was higher than that without flow signal (60.61% vs 32.82%, P <0.01). [Conclusion] The fine needle aspiration cytology guided by color Doppler ultrasonography has certain value in differentiating the <1cm lymph nodes on the left supraclavicular bone and provides important information for the formulation of clinical treatment plans.
