Fibrinolysis shutdown and elevated D-dimer levels have high prognostic capacity for postoperative thromboembolic complications in patients with bone tumors

AbstractSurgical resection of malignant bone tumors is associated with a high risk of venous thromboembolism (VTE). The purpose of this study was to evaluate the association between rotational thromboelastometry (ROTEM) parameters and VTE following oncologic resections, and to evaluate their prognostic capacity for this complication. A prospective observational study was conducted including 113 patients who underwent surgical resection of malignant bone tumors. ROTEM analysis and conventional coagulation studies were performed preoperatively and on the 2nd postoperative day, while patients were followed for the development of VTE. Logistic regression was used to assess the association between ROTEM parameters and occurrence of VTE. The area under the receiver operating characteristic curve (AUC), sensitivity and specificity were calculated as measures of discrimination and predictive accuracy. Fourteen patients (12.4%) developed symptomatic VTE. Development of VTE was associated with shortened INTEM CFT (Odds Ratio [OR] 0.90, 95% Confidence Interval [CI] 0.84  − 0.96, p = 0.004), higher INTEM A10 (OR 1.21, 95% CI 1.07 − 1.36, p = 0.002), higher INTEM MCF (OR 1.22, 95% CI 1.08 − 1.37, p = 0.001) and higher INTEM LI60 (OR 2.10, 95% CI 1.38 − 3.21, p = 0.001). An INTEM LI60 value indicative of fibrinolysis shutdown (≥  98%) had the best predictive accuracy for VTE (AUC = 0.887, 95% CI 0.824 − 0.951, sensitivity = 100%, sp...
