A Correlation Analysis of Postoperative Hypercoagulability and Peripheral Circulating Tumor Cells in Patients with Lung Cancer

Objective: To explore the correlation between peripheral circulating tumor cells and hypercoagulability in patients with lung cancer after surgery. Methods: From January 2017 to December 2021, 89 patients with lung cancer who were treated in the Affiliated Hospital of Hebei University were selected as the research subjects, and a retrospective analysis was conducted to analyze and observe the D-dimer (DD), fibrinogen (FIB), and platelet (PLT) levels in peripheral blood, as well as detect peripheral CTC. Results: There were statistical differences in TMN staging, tumor metastasis, and lymph node metastasis in the clinical data, but there were no statistical differences in gender, smoking history, and pathological classification. After retrospective analysis and comparison of the patients, the DD (mg/ml), FIB (g/L), and PLT (×109/L) levels of the CTC positive group were 3.41 ± 0.58, 3.98 ± 0.87, and 367.26 ± 34.98, respectively; the CTC negative group’s DD (mg/ml), FIB (g/L), and PLT (×109/L) levels were 0.89 ± 0.49, 1.06 ± 0.45, and 234.69 ± 35.69, respectively, and the differences were statistically significant. The factors affecting the prognosis of patients included TMN staging and CTC; the number of CTC positives in the death group was significantly higher than that in the survival group, and there was a statistical difference between the groups. Gender, age, smoking history, pathological type, and surgical resection had no effect on the prognosis of patients. Among the enrolled patients, the survival rate was 71.91%. Conclusion: CTC-positive patients have a higher probability of hypercoagulability after surgery and are prone to tumor metastasis; thus, CTC can be used as a judgment index for the prognosis of patients.
