基于CT影像特征术前预测肺腺癌气道播散研究进展

Advances in the Preoperative Prediction of the Spread of Lung Adenocarcinoma Through Air Spaces Using CT Features

摘要: 气道播散（STAS）是肺腺癌侵袭性行为中的一种，是亚肺叶切除术后肺腺癌复发和预后较差的危险因素。基于计算机断层扫描（CT）的特征与STAS之间的关联，可以预测肺腺癌患者STAS状态，从而帮助临床选择合适的手术类型。本文就肺腺癌STAS的侵袭性以及基于CT特征及其新技术在术前预测STAS的研究现状进行综述。

Abstract: The spread through air spaces (STAS) is one of the aggressive behaviors of lung adenocarcinoma. It is a risk factor for recurrence and an indicator of poor prognosis after sublobectomy. The association between computed tomography (CT)-based features and STAS can predict the STAS status of patients with lung adenocarcinoma, and thus, assist in the clinical selection of the appropriate type of surgery. This article reviewed the aggressiveness of STAS in lung adenocarcinoma and the current research on the preoperative CT prediction of STAS, as well as related new techniques.
