Abstract

Glioma patients were frequently associated with mucosal thickening of the maxillary sinus (MTMS), which reflects mucosal inflammation. We suspected that MTMS is associated with impaired mucosal immune response and correlated with dysfunction in the anti-tumor immune response in diffuse glioma patients. Therefore, the aim of this study was to determine whether the occurrence of diffuse glioma is correlated with MTMS compared to meningioma and control groups. Furthermore, we investigated whether MTMS is associated with overall survival (OS) in glioblastoma (GBM) patients. This study included 343 patients with newly diagnosed diffuse gliomas and 218 patients with meningioma treated at our institution between 2015 and 2018. As control, 201 patients with headache who did not have an intracranial organic lesion were included. Using three-axis MR images, we evaluated the incidence of MTMS in all patients. Additionally, we investigated the relationship between MTMS and OS. The incidence of MTMS in patients with diffuse glioma was significantly higher than that in the meningioma (p < .0001) and control groups (p < .0001). In 128 patients with GBM, MTMS status correlated significantly with OS (p = .0064). We revealed that the incidence of MTMS is significantly associated with patients with diffuse glioma. This suggests that MTMS is indirectly involved in the occurrence of diffuse gliomas. Furthermore, the presence of MTMS correlated significantly with shorter OS in GBM patients, indicating that MTMS is involved in suppression of anti-tumor immune response. Preoperative recognition of MTMS might be useful for improving the clinical management of GBM patients.
