From: Prognosis of resected non-small cell lung cancer with pleural plaques on intrathoracic findings
Prognosis of patients with clinical stage I. A RFS was significantly worse in patients with pleural plaques (5-year RFS rate: 62.5%; 95% CI, 50.9%–72.7%) than in those without pleural plaques (76.4%; 95% CI, 71.5%–80.7%; P < 0.001). B OS was also significantly worse in patients with pleural plaques (5-year OS rate: 64.8%; 95% CI, 52.2%–75.7%) than in those without pleural plaques (83.4%; 95% CI, 78.7%–87.2%; P < 0.001)
