Disease-free survival among stratified subgrouping with risk factors. (A) Disease-free survival curve of patients (8 groups). Group 1: Tumor size >5 cm; visceral pleura invasion (+), with postoperative adjuvant therapy; Group 2: Tumor size >5 cm; visceral pleura invasion (−), with postoperative adjuvant therapy; Group 3: Tumor size >5 cm; visceral pleura invasion (+), without postoperative adjuvant therapy; Group 4: Tumor size >5 cm; visceral pleura invasion (−), without postoperative adjuvant therapy; Group 5: Tumor size ≤5 cm; visceral pleura invasion (+), with postoperative adjuvant therapy; Group 6: Tumor size ≤5 cm; visceral pleura invasion (−), with postoperative adjuvant therapy; Group 7: Tumor size ≤5 cm; visceral pleura invasion (+), without postoperative adjuvant therapy; Group 8: Tumor size ≤5 cm; visceral pleura invasion (−), without postoperative adjuvant therapy. (B) Disease-free survival of patients (4 groups). Score 0: Patients with tumor size ≤5 cm, no visceral pleura invasion and without need of postoperation adjuvant therapy; Score 1: Patients has 1 of following risk factors, such tumor size >5 cm, visceral pleura invasion, the need of postoperative adjuvant therapy; Score 2: Patients has 2 of following risk factors, such tumor size >5 cm, visceral pleura invasion, the need of postoperative adjuvant therapy; Score 3: Patients with tumor size >5 cm, visceral pleura invasion and need postoperative adjuvant therapy.
