We aimed to analyze the relationship between pulmonary adenocarcinoma patients with vascular tumor thrombus and nerve invasion and different CT features.
The preoperative CT scanning data of 86 patients with lung adenocarcinoma who underwent surgical resection in our hospital from January 2020 to January 2022 were analyzed in the form of retrospective analysis. The CT images of all patients were observed, and the relationship between them and vascular tumor thrombus and nerve invasion of lung adenocarcinoma was analyzed. At the same time, the sensitivity, specificity, and accuracy of enhanced CT and plain CT were compared to evaluate the diagnostic efficacy of both.
The results showed that the vascular tumor thrombus of lung adenocarcinoma was mainly related to the solid components and lobulated and calcified tumors in CT images, and the nerve invasion of lung adenocarcinoma was mainly related to the tumors with bronchial inflation sign in CT images ( < 0.05). The sensitivity, specificity, and accuracy of enhanced CT in the diagnosis of vascular tumor thrombus were 78.26%, 96.83%, and 91.86%, respectively, and the sensitivity, specificity, and accuracy in the diagnosis of nerve invasion were 75.00%, 98.72%, and 96.51%, respectively. The sensitivity, specificity, and accuracy of plain CT in the diagnosis of vascular tumor thrombus were 43.48%, 92.06%, and 79.07%, respectively, and the sensitivity, specificity, and accuracy in the diagnosis of nerve invasion were 25.00%, 94.87%, and 88.37%, respectively. The contrast showed that the sensitivity and accuracy of enhanced CT were higher than those of plain CT ( < 0.05), but the difference of specificity was not obvious ( > 0.05).
Solid components and lobulated and calcified tumors in CT signs are closely related to vascular tumor thrombus of lung adenocarcinoma, while patients with bronchial inflation sign are related to nerve invasion.
我们旨在分析肺腺癌伴血管内肿瘤血栓和神经侵犯患者与不同CT特征之间的关系。
采用回顾性分析的形式，分析了2020年1月至2022年1月在我院接受手术切除的86例肺腺癌患者的术前CT扫描数据。观察所有患者的CT图像，并分析其与肺腺癌血管内肿瘤血栓和神经侵犯之间的关系。同时，比较增强CT和平扫CT的敏感性、特异性和准确性，以评估两者的诊断效能。
结果显示，肺腺癌的血管内肿瘤血栓主要与CT图像中的实性成分、分叶状及钙化肿瘤有关，而肺腺癌的神经侵犯主要与CT图像中具有支气管充气征的肿瘤有关（P<0.05）。增强CT诊断血管内肿瘤血栓的敏感性、特异性和准确性分别为78.26%、96.83%和91.86%，诊断神经侵犯的敏感性、特异性和准确性分别为75.00%、98.72%和96.51%。平扫CT诊断血管内肿瘤血栓的敏感性、特异性和准确性分别为43.48%、92.06%和79.07%，诊断神经侵犯的敏感性、特异性和准确性分别为25.00%、94.87%和88.37%。对比显示，增强CT的敏感性和准确性高于平扫CT（P<0.05），但特异性差异不明显（P>0.05）。
CT征象中的实性成分、分叶状及钙化肿瘤与肺腺癌的血管内肿瘤血栓密切相关，而具有支气管充气征的患者与神经侵犯有关。
