Serum thymidine kinase 1 measurement in health check-up / 中华健康管理学杂志

ABSTRACT

Objective To evaluate the utility of serum thymidine kinase 1(STK1)in health screening.Methods A total of 8896 adults who participated in health check-up during November 2009 and November 2010 were tested for STK1 by using sensitive chemiluminescence's dot blot assay.Results The level of STK1 of group A(STK1 ＞ 2 pmol/L)was much higher than that of the group B(STK1 ＜ 2 pmol/L)[(5.47 ±4.23)vs(0.62 ±0.48)pmol/L;t =11.90,P =0.00].The STK1 level was not correlated with gender.However,the mean age of individuals in the group A was higher than that in the group B[(48.2 ± 12.0)vs(41.8 ± 12.3)years; t =5.37,P =0.00].The positive detection rate of STK1 was 1.2％(108/ 8896).In the group A,there were 1.9％ pre-or post-treatment malignancy,27.8％ pre-malignant tumor or benign disease,36.0％ nontumorous proliferation disease,14.8％ hepatitis B virus/HP infection,10.2％fatty liver,and 9.3％ other diseases.No pre-treatment malignancy and pre-malignancy were found in the group B.Conclusion STK1 measurement could reflect the situation of cell proliferation and predict the risk of any type of malignancy.
