Abstract:
Objective To investigate the expression levels of basic leucine zipper and W2 domain 2 (BZW2) and isovaleryl-CoA dehydrogenase (IVD) in hepatocellular carcinoma (HCC) and evaluate their effect on clinical prognosis of liver transplant recipients with HCC. Methods Pathological specimens and clinical data of 87 liver transplant recipients with HCC were collected and retrospectively analyzed. The recurrence and metastasis of HCC after liver transplantation were assessed. Immunohistochemical staining was used to detect the expression levels of BZW2 and IVD. The relationship between BZW2, IVD and clinicopathological parameters of HCC and their effect on postoperative recurrence and clinical prognosis of the recipients was analyzed. Results Among 87 recipients, 31 cases recurred with a recurrence rate of 36%. HCC recurred at postoperative 2-49 months and the median recurrence time was postoperative 7 months. Immunohistochemical staining demonstrated that the positive expression rate of BZW2 in the HCC tissues was significantly higher than that in normal liver tissues (76% vs. 30%), and the positive expression rate of IVD was significantly lower compared with that in normal liver tissues (51% vs. 69%) (both P < 0.01). BZW2 expression was significantly correlated with tumor diameter and tumor capsule (both P < 0.05), whereas IVD expression was significantly associated with tumor diameter, alpha-fetoprotein (AFP) level, tumor, node and metastasis (TNM) staging and whether vascular invasion was found or not (all P < 0.05). In the high BZW2 expression group, the cumulative recurrence rate of HCC was significantly higher and the cumulative survival rate was significantly lower than those in the low BZW2 expression group. In the low IVD expression group, the cumulative recurrence rate of HCC was significantly higher and the cumulative survival rate was significantly lower compared with those in the high IVD expression group (all P < 0.05). Conclusions The expression level of BZW2 protein is up-regulated, whereas that of IVD protein is down-regulated in the HCC tissues. Moreover, the cumulative recurrence rate of HCC is relatively high and the cumulative survival rate is relatively low in liver transplant recipients with high BZW2 expression and low IVD expression.
