Expressions of Nucleoside Diphosphate Kinase (nm23)in Tumor Tissues are Related with Metastasis and Length of Survival of Patients with Hepatocellular Carcinoma

Funds:  National Basic Research Program of China (973 Program)(2007CB310505)%China Mega-Project for Infectious Disease(2009ZX10004-101)%the SKLID development Grant(2008SKLID102%2008SKLID202)
  • Objective To evaluate the relationship of expressions of nucleoside diphosphate kinase (nm23) and proliferating cell nuclear antigen (PCNA), as well as apoptosis, with the prognosis of HCC patients by analyzing their pathological and clinical data. Methods The expressions of nm23 and PCNA were analyzed by immunohistochemistry and the apoptotic phenomena were detected by TUNEL technique in the liver samples from 43 HCC tissues, 39 para-neoplastic tissues, and 10 normal tissues.The mean apoptosis index (AI) and proliferative index (PI) in individual sample were calculated. Results As shown by the detection, 32.6% of carcinomas had negative nm23 signal in tumor tissues, whereas all para-neoplastic and normal tissues had positive nm23. The AI in nm23 positive HCC was significantly higher than that in nm23 negative one, with statistical difference (P<0.05). Furthermore, the expressions of nm23, and the values of AI and PI were contrastively analyzed with some main pathological and clinical data of HCC. It revealed that HCC with extrahepatic metastasis showed remarkable correlation with the negative nm2.3 (P=0.013) and higher PI values of HCC (P=0.015). The disease-free survival in HCC patients with negative nm23 expression was significantly poorer than that in patients with positive nm23 expression. Conclusion These data suggest that expressions of nm23 protein in rumor tissues are correlated with occurrences of metastasis and length of survival of the HCC patients, which may be an indicator for their prognosis.
