Patients and Methods: C-CTC detection was the main evaluation item, which was analyzed using the receiver operating characteristic curve to calculate areas under the curves (AUCs) for the variables. Additionally, the two-year recurrence-free survival rates (2Y-RFSRs) were analyzed. Results: Among the 84 patients examined, SS, CEA, and SUVmax had AUCs>0.7, and were independent. Their thresholds were 2.1 cm, 7.5 ng/ml, and 2.9, respectively. The 2Y-RFSR were significantly better in the non-C-CTC group (n=58) and in the group of patients without high levels of these predictors (n=32). Conclusion: SS, CEA level, and SUVmax predicted postoperative CTC detection in pulmonary adenocarcinoma patients.
