Abstract: Objective: To evaluate and integrate the best evidence of venous thromboembolism risk assessment in tumor patients, so as to provide reference for reducing the incidence of venous thromboembolism in cancer patients. Methods: All evidence on the risk assessment of venous thromboembolism in cancer patients including guidelines, systematic evaluation, Meta-analysis, expert consensus, best clinical practice, evidence summary and original studies was obtained from PubMed, Evidence -Based Health Care Center Database, BMJ Best Practice, Cochrane Library, the UK National Institute of Clinical Medicine Guidelines, the USA Guidelines, Embase, CNKI, Wanfang Database and the Chinese Medical Biobank. The retrieval time was ranged from August 2001 to August 2022. Results: A total of 8 articles were included, including 2 systematic reviews and 6 guidelines. Four categories of risks including individual factors, tumor characteristic related factors, tumor treatment related factors and biomarkers were summarized with a total of 14 best evidences. Conclusion: Early and comprehensive risk assessment of venous thromboembolism is crucial to the prevention of tumor patient -related thrombosis. Medical staff should establish the system, procedures and practical standards of venous thromboembolism risk assessment of tumor patients according to the specific situation of the hospital and the relevant evidence-based medical evidence, so as to improve the quality of care.
