Abstract:
Objective To investigate the values of serum thymidine kinase 1 (TK1) and soluble NKG2D (natural killer cell group 2D) ligand (soluble major histocompatibility complex class Ⅰ-related chain A,sMICA) in predicting the prognosis of colorectal cancer patients undergoing radical resection.Methods 45 patients and 45 healthy subjects were included.Perioperative serum TK1 and NKG2D ligand levels were measured in 45 patient and 45 healthy controls.Patients were divided into high TK1 group and low TK1 group,and high sMICA group and low sMICA group according to the ROC.Results Perioperative TK1 were (4.42 ± 1.42) and (2.98 ± 0.54) pmol/L,sMICA were (135 ± 79) and (100 ± 81)pg/ml,which were significantly higher than those in healthy controls (P =0.000).The postoperative TKI and sMICA levels decreased significandy (P =0.000 and 0.042).The 3 and 5 years cumulative survival rates in the high TK1 group were 84％ and 34％,compared with that of 90％ and 75％in the low TK1 group (P =0.023).The 3 year and 5 year cumulative survival rates in high sMICA group were 61％ and 31％,compared with 71％ and 52％ in low sMICA group (P =0.148).Conclusion Patients serum thymidine kinase levels were negatively corelated with the prognosis of colorectal cancer after radical resection.
