Abstract:
Objective To analyze the correlation between thrombelastography(TEG)and coagulation, platelet count(PLT)in patients with malignant tumor.Methods Retrospectively analyzed the clinical data of 241 cases with tumor who were performed TEG,coagulation and blood test in the same day in Chongqing Cancer Institute from November 2016 to March 2017.Linear correlation and regression were carried out to an-alyze relationship among the parameters.The number of patients with positive blood clotting,PLT and TEG parameters were counted,and the χ2test was used to compare the difference between them.Using Mann-Whit-ney U test to compare the differences between multiple parameters of liver cancer,breast cancer,and pancreatic cancer.Results The R value of TEG parameters in patients with malignant tumor was positively correlated with APTT,negatively correlated with TT,DD and FDPs.K was positively correlated with APTT and TT, and negatively correlated with FIB and PLT.The relationship between α and FIB,PLT were positive,between APTT and TT were negative.MA was positively correlated with FIB and PLT,negatively correlated with TT, CI was positively correlated with FIB and PLT,and negatively correlated with APTT(P<0.05).The correla-tion between FIB,PLT and MA was the highest.And the linear regression equation of TEG parameters and coagulation indexes was obtained.The positive rate of TEG was lower than that of coagulation(P<0.05). Same certain differences of TEG and coagulation parameters were existed in liver cancer,breast cancer and pancreatic cancer patients.Conclusion TEG is significantly associated with PLT and conventional coagulation test,and the results of TEG and conventional coagulation test are consistent to a certain degree,but the overall agreement is generally not interchangeable.TEG might be play a complementary role with coagulation tests and platelet counts.And the TEG of different cancer types is not exactly the same as the coagulation parameters.
