The expression of FZD7 and IL-6 in primary hepatocellular carcinoma and the impact on the prognosis / 中华普通外科杂志

ABSTRACT

Objective To investigate the expression of FZD7 (frizzled homolog protein7,FZD7) and IL-6 (interleukin-6,IL-6) in primary hepatocellular carcinoma(HCC) and the impact on the prognosis.Methods Immunohistochemistry(IHC) was used to detect the expression level of FZD7 and IL-6 in 68 HCC tissues,30 para-carcinoma tissues and 10 healthy controls from patients with hepatic hemangioma.Patients were followed-up for survival analysis.Results The expression ratio of FZD7 in HCC tissue,paracarcinoma tissue and healthy controls were 72％,53％ and 0 (P ＜ 0.001),the ratio of IL-6 expression was respectively 69％,57％ and 0 (P ＜0.001).The expressions of FZD7 were positively correlated with that of AFP level (x2 =7.059,P =0.035),pathology classification (x2 =4.732,P =0.043),and the infection of HBs (x2 =3.508,P =0.032).The overall survival (65 ％ vs.84％,x2 =5.525,P ＜ 0.05) and the disease free survival (33％ vs.75％,x2 =5.991,P ＜0.05) of HCC patients with co-positive was significantly lower than that with co-negative expression of FZD7 and IL-6.Conclusion FZD7 and IL-6 play a critical role in development and progression of HCC.
