Kaplan-Meier curves for predicting progression-free survival and overall survival in patients with and without adjuvant therapy. A, Progression-free survival;B, overall survival. For blue line, patients were detected with CTC <4 and received surgery only. For purple line, patients were detected with CTC ≥4 and received surgery only. For black line, patients were detected with CTC ≥4 and then received AP-chemotherapy scheme (pemetrexed, disodium, and cisplatin) following surgery. For red line, patients were detected with CTC ≥4 and then received Gefitinib-targeted therapy following surgery. CTC indicates circulating tumor cell.
