Abstract:

Objective To analyze risk factors of postoperative venous thromboembolism (VTE) in multiple myeloma (MM) patients. Methods One hundred and fifty seven MM patients initially treated in the Department of Hematology, the First Hospital of Shanxi Medical University from January 2012 to January 2022 were enrolled. Patients were assigned to the non-VTE group (n=124) and VTE group (n=33) based on the existence of VTE. Clinical data of the two groups were compared, and risk factors for VTE in MM patients after treatment were analyzed. Results The results of univariate analysis showed that the age, recent surgical history, recent fracture history, D-dimer>0.55 mg/L, use of immunomodulatory drugs, and IMPEDE score ≥8 points were related to the occurrence of VTE in MM patients after treatment (P<0.05). Binary multivariate logistic analysis showed that the age, recent surgical history, D-dimer >0.55 mg/L, and use of immunomodulatory drugs were the risk factors for the occurrence of VTE in MM patients.Conclusion The assessment of the risk of VTE in MM patients after treatment should be comprehensively combined with the patient's age, medical history, laboratory indicators and treatment plan. In view of the fact that the relevant score for MM patients in foreign countries may not be fully applicable to the Chinese population, further research is needed to develop the risk score for VTE in Chinese MM patients and verify it.
