Tumor spread through air spaces (STAS) as a new pathological invasion mode is closely related to many clinicopathological factors. In lung adenocarcinoma, micropapillary and solid pathological subtypes are most related; STAS for early stage lung adenocarcinoma, surgical type of lobectomy seems to benefit better than sublobar resection, which may up-regulate the pathological stage of early lung cancer; Moreover, STAS is closely related to squamous cell carcinoma and other non-small cell lung cancer (NSCLC). In addition, intraoperative frozen-section pathological detection of STAS is difficult and controversial. STAS as an independent risk factor for tumor recurrence is also an important factor indicating poor prognosis. This paper reviews the research status and progress of STAS.
