Abstract:
Objective To study the correlation between the clinical characteristics of HCC patients with different phenotype circulating tumor cells in the peripheral blood.Methods 77 patients with HCC and 21 patients with benign liver diseases treated at Zhujiang Hospital of Southern Medical University from April 2015 to December 2016 were retrospectively studied.The CanPatrolTM System was adoptedto detect epithelial-mesenchymal phenotype CTCs in the peripheral blood.This study aimed to clarify whether the epithelial-mesenchymal phenotype CTCs were specifically originated from the tumorand to investigate the correlation between CTCs and the clinical features of the patients.Results Using epithelial and mesenchymal markers,the CTCs were divided into three subtypes:epithelial,mesenchymal and mixed CTCs.No epithelial-mesenchymal phenotype CTCs were detected in patients with benign liver diseases.The positivity rates of epithelial,mixed and mesenchymal CTCs in the peripheral blood of 77 patients with HCC were 37.7％ (29/77),74.0％ (57/77) and 50.6％ (39/77),respectively.The positivity rates of epithelial-mesenchymal phenotype CTCs in patients with HCC were significantly higher than the group of patients with benign liver diseases (P ＜ 0.05).The positivity rates of epithelial CTCs were significantly correlated with AFP,number of tumor and portal vein tumor thrombus (P ＜ 0.05).The positivity rates of mixed CTCs were significantly correlated with portal vein tumor thrombus,tumor differentiation and BCLC stage (P ＜ 0.05).The positivity rates of mesenchymal CTCs were significantly correlated with tumor size,portal vein tumor thrombus,tumor differentiation and BCLC stage (P ＜ 0.05).Conclusions The positivity rates of epithelial,mixed and mesenchymal CTCs were closely related to different aspects of clinical characteristics of patients with HCC.These CTCs may serve as indicatorsto evaluatethe progress of HCC.
