ABSTRACT
Objective To investigate the value of circulating tumor cell(CTC)in non-small cell lung can-cer(NSCLC)and its relationship with clinicopathological features and prognosis. Methods This study totally in-cluded 59 patients with histologically confirmed diagnosis of NSCLC. CTCs were quantified in 7.5 mL peripheral blood samples collected prior to surgery using CellSearch system(Veridex). Statistical analysis of the relationship between CTC positive rate and clinical data,pathological characteristics and prognosis were performed. Results The CTC positive rate was 30.51% and it was significantly correlated with distant metastasis(P = 0.012),TNM stage(P = 0.002)and lymph node metastasis(P = 0.002). The 5-year overall survival rate in the CTCs positive group was significantly lower(22.22% vs. 68.29%,P = 0.005)and the cumulative recurrence was significantly higher(55.55% vs.29.27%,P=0.022)compared with the CTCs negative group.The univariate analysis indicated that the prognostic influencing factors included TNM stage,lymph node metastasis,distant metastasis and CTCs re-sults and the multivariate analysis showed that TNM stage,distant metastasis and CTCs positive were significantly correlated with overall survival and cumulative recurrence(P<0.05). Conclusion CTC is an independent prog-nostic indicator for NSCLC.
