Abstract
BACKGROUND
Previous related studies have found that the levels of tumor-associated macrophages (TAMs) were correlated with prognoses in hepatocellular carcinoma. However, the prognostic value of TAMs for East Asian HCC patients remains inconclusive.
METHODS
Our objectives were to systematically review the performance and explore the prognostic and clinical value of TAMs in patients with HCC. A total of 23 relevant studies of 4389 patients were included into our meta-analysis. And the work has been reported in line with PRISMA guidelines.
RESULTS
The results demonstrated that increased expression level of peritumoral infiltrated CD68+ macrophages had a poor prognostic value on overall survival (OS), disease free survival (DFS) and recurrence-free survival (RFS). However, there was no correlation between disease-free survival (DFS) and the abundance of CD68+ TAMs both in intratumoral regions. Additionally, low density of CD169+, high density of CD206, and high density of CD204+ TAMs had a worse prognostic value on OS while the CD163+ TAMs had no diagnostic value on OS. The densities of CD68+ TAMs exhibited significantly correlation with AFP level and vascular invasion. The levels of CD169+ TAMs showed apparent relation to vascular invasion and TNM stages.
CONCLUSION
These findings indicate that TAMs may accomplish as significant prognostic biomarkers for East Asian HCC patients. However, further researches should be performed to estimate the clinical value of TAMs in HCC.
