Özet
Purpose: Meningiomas are generally benign; however, they have high recurrence rates. The tumor microenvironment, particularly tumor-associated macrophages (TAMs) may play a role in tumor progression and recurrence. This study aimed to investigate the role of TAMs in tumor recurrence and patient survival in meningiomas, as well as their associations with clinicopathological and prognostic parameters. Methods: A total of 146 primary meningiomas were evaluated. The presence of TAMs was examined morphologically in hematoxylin-eosin stained tissue sections. The clinicopathological and prognostic data were analyzed. Recurrence-free survival (RFS), overall survival (OS), and disease-free survival (DFS) were evaluated. Results: TAMs were detected in 30 of 146 (20.5%) meningiomas. Patients with TAM-positive meningiomas were younger than TAM-negative meningiomas (p = 0.04). There was no statistically significant association between the presence of TAM and gender, tumor size, tumor location, Simpson grade, or WHO grade (p > 0.05). Recurrences occurred more frequently and at an earlier stage in cases with TAM-positive meningiomas (p = 0.001). Cox regression analysis identified TAMs as an independent risk factor for recurrence. However, no significant association was observed between the presence of TAM and OS or DFS (p > 0.05). Conclusion: The presence of morphologically identified TAMs in meningiomas was found to be associated with tumor recurrence and shorter recurrence-free survival times. These findings suggest that a tumor microenvironment rich in morphologically identified TAMs may be associated with the risk of recurrence in meningiomas. However, morphological assessment of TAMs constitutes a major limitation of this study. Larger multicenter studies are needed to clarify the prognostic significance of TAMs in meningiomas.
