Abstrakt: | Background: Tumor recurrence following the surgical resection of lung cancer (LCa) reduces long-term disease-free survival rates. This study aimed to investigate the association of pulmonary venous blood (PVB) circulating tumor cells (CTCs) with the clinicopathological features of patients with early-stage lung adenocarcinoma. Methods: A total of 120 cases were enrolled, including 24 healthy controls, 36 patients with lung benign tumors, and 60 early-stage lung adenocarcinoma patients. Cells displaying a profile of human chromosome 8 specific sequence (CEP8) + /4',6-diamidino-2-phenylindole (DAPI) + /leukocyte-specific antibodies (CD45) ‒ were regarded as CTCs, and counts of ≥2 CTCs per 3.2 mL of PVB were considered positive. The association of CTC counts with clinical parameters were analyzed. Results: The number of CTCs were significantly higher in early-stage lung adenocarcinoma patients compared to benign or normal control group. Moreover, increased CTCs in lung adenocarcinoma was closely associated with tumor invasion, pathological staging and the epidermal growth factor receptor ( EGFR ) mutations (P<0.05), whereas no significant difference was observed between CTC counts and age, sex, smoking history, pathological cell morphology or immunohistochemical indicators (P>0.05). Univariate and multivariate Cox's proportional hazards regression confirmed that CTC counts were an independent indicator for the prediction of tumor invasion, pathological staging, and EGFR mutations. Conclusions: Our data suggest that CTC counts correlate with tumor invasion, pathological staging, and EGFR mutations. CTCs therefore represent promising biomarkers for the surveillance of lung adenocarcinoma progression.
