ABSTRACT
Objective To analyze the clinical and pathological characteristics of 35 hepatocellular carcinoma (HCC) patients with bile duct tumor thrombi (BDTT),and to investigate the expressions of CD133,CD90,EpCAM,CK19,VEGF,and C-kit in the tumor tissues.Methods 35 HCC patients with BDTT out of 943 HCC patients who underwent surgical treatment were studied.The expressions of biomarkers in tissue specimens were determined by immunohistochemistry.35 HCC patients without BDTT were selected using the method of stratified sampling as a control group.Results In 19 of 35 patients,the diameters of the primary tumor were less than 5 cm (range 0 ～ 17 cm,average 6.9 ± 0.7 cm).When compared to the control group,most of the primary tumors were moderately to lowly differentiated (33/35,94％ vs 18/ 35,51％),had incomplete capsules (18/35,51％ vs 3/35,8％) and micro vascular invasion (29/35,83％ vs 7/35,20％).The positive expression rates of CD90,EpCAM,CK19,VEGF,CD133,and C-kit in the group of patients with HCC with BDTT and in the control group were 82.9％,77.1％,71.4％,85.7％,80.0％,80.0％ and 57.1％,54.3％,34.3％,65.7％,54.3％,51.4％,respectively.The 1-,2-,3-year postoperative survival rates of the HCC patients with BDTT were 69％,37％,20％ respectively which were worse than the HCC patients without BDTT (1-,2-,3-year postoperative survival rates were 88％,72％,62％ respectively,P ＜ 0.05).Conclusions The prognosis of HCC patients with BDTT was worse than HCC patients without BDTT.The expressions of liver stem cell biomarkers in the tumor specimens of the group of HCC patients with BDTT were higher than the control group.These findings prompt that this kind of HCC originate from liver stem ceils.
