Risk factors of venous thromboembolism for liver tumors: a systematic review and meta-analysis.

Background: Venous thromboembolism (VTE) is a significant complication in liver tumors patients, and understanding the associated risk factors is essential for effective risk assessment, prevention, and management strategies. This systematic review and meta-analysis aimed to identify key risk factors and their clinical implications for VTE in liver tumors patients.

Methods: A comprehensive search of multiple databases was conducted to identify relevant studies. Eligible studies were selected, and odds ratios (ORs) and 95% confidence intervals (CIs) were extracted and synthesized for meta-analysis.

Results: A total of 11 studies involving 73,652 liver tumors patients and 2049 VTE cases were included. The analysis identified several significant risk factors for VTE in liver tumors patients. Age (≥65 years), male gender, high BMI, diabetes, hepatitis B and C infections, elevated D-dimer and AST levels, reduced albumin levels, and MELD score were all associated with increased VTE risk.

Conclusion: This systematic review and meta-analysis revealed several key risk factors for VTE in liver tumors patients, these findings highlight the importance of risk assessment, prevention, and management strategies in this high-risk population. Further research with larger sample sizes and standardized methods is needed to strengthen the existing evidence and validate these findings.
