EP02.03-028 Pathologic Risk Factors for Recurrence in Early Stage Invasive Lung Adenocarcinoma with Tumor Spread through Air Spaces

Tumor spread through air spaces (STAS) is a newly adopted pathologic pattern of invasion of cancer cell nests spreading into air spaces in the lung parenchyma adjacent to the border of the main tumor and well-known risk factor of recurrence. The aim of this study was to evaluate relevant pathologic risk factors in early stage lung adenocarcinoma containing tumor spread through air spaces (STAS) treated with surgical intervention.
