ABSTRACT
【Objective】 To explore the value of thromboelastogram (TEG) in evaluating coagulation function of patients with liver cancer. 【Methods】 102 patients with liver cancer and 48 with hepatic hemangioma from Department of Hepatobiliary Surgery, Nanyang Central Hospital from August 2017 to September 2020 were retrospectively analyzed. TEG indicators (R, K, Angle, MA, CI, and G value) and routine coagulation indicators (Plt, PT, INR, APTT, FIB, and TT) of those patients and basic clinical data of liver cancer patients were collected, and the difference of detection parameters between the liver cancer group and liver hemangioma group was compared; The difference of TEG parameters in liver cancer patient subgroups was compared, and the correlation between TEG and routine coagulation tests in liver cancer patients was analyzed using Spearman rank correlation analysis. The sensitivity of the two detection methods in detecting the coagulation status of patients with liver cancer was compared. 【Results】 1) Compared with patients with hepatic hemangioma, Plts decreased significantly (166.6±108.824 vs 224.10±54.933, P<0.001), while PT, INR and APTT values increased significantly (13.12±2.052 vs 11.421±0.884, 1.156±0.191 vs 1.00±0.074, 29.977±5.333 vs 26.954±5.269, all P<0.05) in patients with liver cancer; MA and G values in patients with liver cancer were lower (56.991±11.574 vs 60.069±5.094, 7.667±4.682 vs 7.725±1.709, P<0.05); 2) Compared with newly diagnosed liver cancer patients, the Plt of re-diagnosed liver cancer patients decreased significantly(125.78±79.673 vs 188.86±116.437, P<0.05); the R and K value increased significantly (7.594±2.601 vs 6.058±1.739, 3.453±2.402 vs 2.438±1.990, all P<0.05), while the Angle, MA, CI and G value decreased significantly (53.897±12.288 vs 61.495±9.949, 53.556±11.407 vs 58.865±11.313, -3.494±4.253vs -0.836±3.180, 6.311±3.209 vs 8.406±5.191, all P<0.05); 3) There were significant differences in TEG parameters (R value excluded) between liver resection, transhepatic arterial chemoembolization and conservative treatment (P<0.05); 4) The R, K value of patients with liver cancer were negatively correlated with the Plt value, while the Angle, MA, CI, and G value were positively correlated with Plt value (P<0.001); the K value was negatively correlated with the Fib value, while the Angle, MA, CI, G value were positively correlated with Fib value (P<0.001); the R and K value were positively correlated with TT value, while the Angle and CI were negatively correlated with TT value (P<0.05); 5) The detection rate of hypocoagulability by TEG and routine coagulation testing was 18.63% (19/102) and 7.84%. 【Conclusion】 Compared with the newly diagnosed liver cancer patients, re-diagnosed liver cancer patients showed hypercoagulability. TEG can diagnose the coagulation abnormalties more sensitively, and help reduce the risk of bleeding.
