Background:
This study aimed to systemically explore the risk factors of secondary infection/recurrence after ablation in patients with liver cancer.
Methods:
Relevant literature in PubMed, EMbase, and Cochrane Library databases were searched with keywords including "liver cancer or carcinoma," "ablation," "infectious or infection or recurrence," and "risk factor or relevant factor or correlative factor or influencing factor." Meta-analyses were performed and forest plots were drawn for risk factors, including the tumor size and location, number of tumor nodules, hepatitis B virus (HBV) DNA levels, serum alpha fetal protein (AFP) levels and serum albumin levels, Child-Pugh Class, and lack of antiviral therapy. A funnel plot was drawn to assess the publication bias.
Results:
A total of 23 studies were included from the initial 701 potentially relevant articles. Our meta-analyses showed that a large tumor size (odds ratio [OR] = 1.58; 95% confidence interval [CI]: 1.31-1.92); proximity to the colon, large vessels, and large hepatic vein (OR = 4.10; 95% CI: 2.26-7.43); multinodular tumor (OR = 2.10; 95% CI: 1.46-3.03), the higher HBV DNA levels (OR = 1.34; 95% CI: 1.09-0.64); higher serum AFP levels (OR = 1.56; 95% CI: 1.18-2.05), lower serum albumin levels (OR = 1.67; 95% CI: 1.06-2.65); Child-Pugh Class B and Class C (OR = 1.27; 95% CI: 1.05-1.54); and lack of antiviral therapy (OR = 1.75; 95% CI: 0.93-3.28) were associated with an increased risk of post-ablation infection/recurrence in patients with liver cancers.
Conclusion:
Our results indicated that the tumor size and location, number of tumor nodules, HBV DNA levels, serum AFP levels and serum albumin levels, Child-Pugh Class, and lack of antiviral therapy were the risk factors for post-ablation infection/recurrence in patients with liver cancer. Here, we have provided directions for the clinical prevention of secondary infection/recurrence in patients with liver cancer who underwent ablation therapy.
