To Investigate Middle-old Ages Serum Thymidine Kinase 1 on Physical Management Tumor Screening

Objective Observe middle-old age which above 45 years old cases serum thymidine kinase 1(STK1)on tumor mass screening.Methods 620 cases on physical examination testing STK1 by using sensitive chemiluminescence’s dot blot assay.Assess the significance of STK1 in diagnosis and prognosis of cancer.Results Positive group(STK1 value 6.72±4.05pmol/L) was higher than negative group(STK1 value 0.86±0.35pmol/L)(P0.05).Both group STK1 value was not significant difference with gender(P0.05).There were 35 positive cases(positive rate 5.6%) including cancer 2 cases,benign tumor 18 cases,pre-malignant tumor 5 cases,nontumor profiferation disease 5 cases and infectious disease 5 cases.Conclusion STK1 can act as general tumor marker on carsinoma mass screening in middle-old ages and fit in with cost-effect because it is not expensive and just serum testing.
