Comparison of survival outcomes between patients with different tumor diameters. a Overall survival (OS, months) in patients with a tumor diameter < 5 cm and those with a tumor diameter ≥ 5 cm. b Progression-free survival (PFS, months)in patients with a tumor diameter < 5 cm and those with a tumor diameter ≥ 5 cm. c Overall survival (OS, months) in patients with a tumor diameter < 7 cm and those with a tumor diameter ≥ 7 cm. d Progression-free survival (PFS, months)in patients with a tumor diameter < 7 cm and those with a tumor diameter ≥ 7 cm
