Tumor spread through air spaces (STAS) is a newly identified invasion pattern in lung adenocarcinoma. This study aimed to analyze and validate the clinical impact of tumor STAS in surgically resected lung squamous cell carcinoma (SQCC). ⋯ We found that STAS was detected in 19.1% of surgical resected SQCC, and it was associated with recurrence and worse survival in stage I SQCC, but not in stage II and III SQCC. Therefore, we suggest that STAS is a useful predictor of recurrence and prognosis in stage I lung SQCC.

This study of a large, contemporary national database evaluated postoperative outcomes and overall survival (OS) for malignant pleural mesothelioma (MPM) by facility volume. ⋯ This is the largest investigation to date assessing facility volume and outcomes following surgery for MPM. Although no independent effects on OS were observed, postoperative outcomes were more favorable at HVFs. These findings have implications for postoperative management, patient counseling, referring providers, and cost-effectiveness.
