523P Survival outcomes in patients with spread through air spaces (STAS) following resection for pulmonary adenocarcinoma

Lung cancer is the leading cause of cancer-related mortality worldwide, and tumor stage is the main prognostic determinant. Spread through air spaces (STAS), first described in 2015, has recently emerged as an adverse prognostic factor. This study aimed to evaluate the impact of STAS on survival, its association with pathological features, and its implications for surgical management in pulmonary adenocarcinoma.
