Expressions of Bag-1 and VEGF in hepatocellular cancer and their relationship with prognosis / 肿瘤研究与临床

ABSTRACT

Objective To detect the Bag-1 and VEGF expressions in HCC tissues,cancerous liver tissues and normal liver tissues,and to explore their relationship with prognosis.Methods Immunohistochemical staining (SP method) was used to detect Bag-1 and VEGF in 60 cases of hepatocellular carcinoma specimens,next to the 30 cases of hepatocellular carcinoma in liver tissue,and 14 cases of normal liver tissue specimens,and their clinicopathological features were analyzed.Results Bag-l,VEGF expression rates were highest in HCC tissues [80.0 ％ (48/60),73.3 ％ (44/60)] and with adjacent tissues [46.7 ％ (14/30),43.3 ％ (13/30)],normal liver tissue [28.6 ％ (4/14),21.4 ％ (3/14)] expression rates had differences (P ＜ 0.05).Bag-1,VEGF expression had relationship with liver cancer staging,lymph node metastasis,tumor thrombosis formation,the correlation between the presence or absence of capsule formation (P ＜ 0.05),while had no relationship with the patient gender,age,tumor grade,tumor size,and alpha-fetoprotein (AFP) and other factors correlation (P ＞ 0.05).Bag-1 and VEGF expression in HCC specimens positive 40 cases,while negative eight cases,both in HCC tissues expression was positively correlated (P ＜ 0.05).Bag-1,VEGF positive expression in patients 1-year,2-year survival rates were less than negative patients,the survival time of patients with positive group was significantly lower than the negative patients (P ＜ 0.05).Conclusion Bag-1 and VEGF expressions are closely related with biological characteristics of liver cancer,and which is closely related to the prognosis of patients with hepatocellular.
