摘要

目的:通过剪切波弹性成像(shear wave elastrography,SWE)获得鉴别腮腺良恶性病变及良性亚组分型的杨氏模量值,并分析其诊断价值。方法:选取2019年6月至2020年1月以腮腺占位性病变住院的74例患者(76个结节),对所有患者的腮腺病变在术前或穿刺活检之前进行SWE技术检查,获得相应的杨氏模量值,并与组织学检查结果进行比较和分析。结果:在76个结节中,良性病变69例,恶性病变7例。良性病变中多形性腺瘤(pleomorphic adenoma,PA)占37.6%(26例),单形性腺瘤(monomorphic adenoma,MA)占30.0%(23例),淋巴结占21.7%(15例)。所有腮腺肿瘤杨氏模量最大值及平均值均高于腮腺内淋巴结,差异均有统计学意义(P<0.05)。PA与MA比较杨氏模量最大值及平均值差异有统计学意义(P<0.05)。腮腺恶性病变与良性病变比较,杨氏模量最大值及平均值差异有统计学意义(P<0.05),但是恶性病变与良性病变各亚组之间比较,除淋巴结组之外,杨氏模量最大值及平均值差异均无统计学意义(P>0.05)。结论:SWE技术虽然在鉴别腮腺良恶性肿瘤之间没有达到预期效果,但在良性亚组(PA与MA、淋巴结与其他腮腺肿瘤)之间有重要的诊断意义。

Abstract

Objective: To obtain the Young’s modulus of benign and malignant parotid gland lesions and benign subtypes by shear wave elastography (SWE), and analyze its diagnostic value. Methods: From June 2019 to January 2020, 74 patients (76 nodules) with parotid space-occupying lesions were selected to have SWE examination before surgery or puncture biopsy so as to obtain the relevant Young’s modulus values. The Young’s modulus values were compared with the results of histological examination, and statistical analysis was performed together. Results: In the 76 nodules, 69 cases were benign lesions and 7 cases were malignant lesions. Among the benign lesions, pleomorphic adenoma (PA) accounted for 37.6% (26 cases), monomorphic adenoma (MA) accounted for 30.0% (23 cases), and lymph nodes accounted for 21.7% (15 cases). The maximum and average Young’s modulus of all parotid tumors were higher than those in the parotid lymph nodes, and the differences were statistically significant (P<0.05). There were also statistic significance in PA and MA comparing with the maximum and average Young’s modulus values (P<0.05). Comparing the parotid malignant lesions with benign lesions, the maximum and average values of the Young’s modulus were statistically significant. However, there was no statistic significance difference in the maximum and average Young’s modulus between malignant and the subgroups of benign lesions, except for the lymph node group (P>0.05). Conclusion: Although SWE technology has not achieved the expected results in identifying parotid benign and malignant tumors, it is significant for benign subgroups (PA, MA, lymph nodes and other parotid tumors).
