Expression of thymidine kinase 1 in primary hepatic carcinoma and its value in prognostic prediction / 实用医学杂志

ABSTRACT

Objective To investigate the expressions of TK1 (thymidine kinase 1) in PHC (primary hepatic carcinoma). Methods TK1 and AFP in serum of 33 cases of PHC (primary hepatic carcinoma), 38 cases of hepatic cirrhosis,36 cases of hepatitis and 35 cases of healthy people were detected by means of Western blot—enhanced chemiluminecence and electrochemiluminescence. Results The difference of TK1 level in PHC group indicated significance when compared with that in hepatic cirrhosis group , hepatitis group and control group (U value was 436.4, 352.1, 163.6, respectively, all P 0.05). Kaplan-Meier curve analysis revealed that PHC patients with TK1≤ 2.0 pmol/L had a significantly shortened overall survival when compared with those with TK1 > 2.0 pmol/L (χ2 = 3.954,P < 0.05). Multivariable Cox regression analysis indicated that the level of TK1 and TNM stage were the independent risk factors for patients with PHC (all P <0.05). Conclusions The detection of TK1 has a certain clinical value in the diagnosis, monitoring and evaluation of the prognosis of the PHC.
