Correlation between Circulating Tumor Cells and Plasma D-dimer and Clinicopathological Characteristics of Patients with Non-small Cell Lung Cancer.

Objective To study the relationship between circulating tumor cells (CTCs) and plasma D-dimer (D-D) and their correlation with clinicopathological characteristics of patients with non-small cell lung cancer (NSCLC). Study design A descriptive study. Place and duration of study Department of Thoracic Surgery, Jinan Central Hospital Affiliated to Shandong University, Jinan, Shandong, China, from December 2015 to August 2019. Methodology Seventy-five patients with NSCLC were selected as the research subjects. The contents of CTCs and D-D were determined and the results were analysed as per objective. Data was analysed quantitatively, using SPSS Version 24.0. Results Forty-five patients with NSCLC were positive for CTCs. The level of D-D in NSCLC patients was significantly increased. The D-D level in CTCs-positive patients was 0.79 (0.43-1.80) mg/L. The levels of CTCs and D-D in NSCLC patients were not affected by gender and pathological subtypes and other factors (p>0.05). CTCs and D-D in peripheral blood of NSCLC patients were significantly correlated with the total stage of lung cancer patients (p Conclusion The levels of CTCs and D-D in peripheral blood of NSCLC patients are significantly correlated with clinicopathological features, and the positive CTCs and high levels of D-D may indicate the late stage of the disease and poor prognosis, and there is a correlation between the two. The combined detection of the two is of great significance in predicting the progress and poor prognosis of NSCLC patients, and can guide the clinical diagnosis and treatment.
