肺癌气道播散的研究概况.

In 2015, the World Health Organization's classification of lung cancer proposed the concept of spread through air spaces (STAS) as a new model for lung adenocarcinoma invasion. STAS refers to the spread of lung cancer cells through the airways in the lung parenchyma beyond the edge of the main tumor. In recent years, with the deepening of STAS research, the results show that STAS as an invasive method is related to other invasive behaviors and metastasis. STAS is closely related to the prognosis of lung cancer and is also independently associated with the risk of recurrence. Notably, the prognosis of STAS-positive patients varies greatly with the choice of surgical methods. In imaging, STAS has its own special imaging features that can be used as a tool for estimating STAS likelihood. Therefore, whether it is possible to determine the presence or absence of STAS by imaging and other methods could become a significant guidance for selecting surgical methods and improving patients' prognosis. This review will focus on the recent research on the association of STAS with imaging, gene mutations, and different types of lung cancer. [ABSTRACT FROM AUTHOR]
