The expression of the DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT) can lead to tumor cell resistance to alkylating agents. Glioblastomas with isocitrate dehydrogenase mutation (IDHmut) were reported to have significantly higher MGMT promoter methylation, which predicted improved outcomes after temozolomide treatment. However, the MGMT methylation status in IDHmut glioma remains controversial. To further explore the associations of MGMT promoter methylation status with other molecular features in IDHmut gliomas, in this work, we analyzed the relationship of MGMT promoter methylation status with 1p/19q codeletion status and age in IDHmut gliomas based on a large Asian (Chinese) cohort. We found that there was no significant difference in MGMT methylation status in IDHmut 1p/19q-codeleted oligodendrogliomas compared to IDHmut astrocytomas, in either primary or recurrent cases. Moreover, the MGMT methylation status was not associated with age. The difference compared to previous research which indicated the MGMT methylation status differed significantly among IDHmut glioma might be caused by differences between populations, indicating that routine assessment of MGMT methylation status in oligodendrogliomas may still be necessary.

This study aimed to compare the safety and efficacy of CyberKnife (CK) versus TomoTherapy for the treatment of brain metastases (BMs). Three cases of BM treated at our hospital – two with CK and one with TomoTherapy – were compared and analyzed. Both treatments showed good therapeutic effects, but CK was more effective. No radiation-related adverse reactions were observed in the three patients. It is concluded that both CK and TomoTherapy can effectively control target lesions by allowing a higher dose in a single treatment while minimizing damage to surrounding normal brain tissue. This can reduce the total number of treatments needed, improve the prognosis of patients, and save medical resources.

Glioblastoma multiforme (GBM) is the most common malignant tumor in the adult central nervous system, and surgery combined with radiotherapy and chemotherapy represents the main treatment regimens. Temozolomide (TMZ) is currently the first-line chemotherapeutic agent used in GBM therapy and is widely used subsequent with surgical resection of GBM. TMZ can significantly prolong the survival time of patients with glioma. However, the high incidence of resistance to TMZ, which seriously affects the overall outcome of GBM treatment, is a serious concern facing clinicians. The mechanisms of resistance to TMZ in patients with GBM include biological processes involving DNA damage repair, cellular autophagy, glioma stem cells, and the tumor microenvironment. Therefore, exploring the mechanisms inducing GBM resistance to TMZ treatment and how to effectively reduce TMZ resistance and improve its efficacy has become an urgent question. This review summarizes the effects and mechanisms of TMZ resistance in the treatment of glioma. It is hoped that intensive investigation of the mechanisms of resistance of TMZ to GBM can lay the foundation for successful outcomes in patients with GBM.

Glioma is the most common primary central nervous system tumor. Despite extensive basic research on the tumor, the overall therapeutic effect of glioma remains unsatisfactory. Glioma grows within the framework of complex neural circuitry, which influences both neural network and tumor biology. On the one hand, the growth of gliomas continuously invades and destroys normal neural structures, which stimulate the dynamic remodeling of neural networks to maintain neural function. On the other hand, glioma can also induce neurons to form synaptic connections with it to promote tumor growth. Interventions targeting the interaction between gliomas and the neuronal circuitry provide opportunities for both tumor therapy and neuroplasticity at the same time. Noninvasive brain stimulation (NiBS) technology can actively regulate the excitability of targeted brain regions which can actively induce the remodeling of neural function and may perturb the interference of neuronglioma synapses. This article will review the interaction between gliomas and neural networks, including tumor-induced neuroplasticity, neuron-glioma synaptic connections, and the application and prospect of NiBS techniques.

Rosai–Dorfman disease (RDD) is a nonneoplastic histiocytic proliferation. RDD is CD1a negative as opposed to Langerhans cell histiocytosis (LCH). The lesion was positive for CD1a immunohistochemistry in our RDD patient, suggesting an overlap with LCH. In addition, our case exhibited granulomatous angiitis (GA) on microscopy. We report the first triad of coexistent intracranial RDD-LCH-GA. A 30-year-old man presented with seizures, limb weakness, and violent behavior for 3 months. There was no fever, lymphadenopathy, or hepatosplenomegaly. Laboratory test results were normal. Radioimaging revealed an 8.6 cm × 7.4 cm × 3.2 cm mass in the parietotemporal lobe. It was hypointense on T1W1 and hypointense on T2W1, suggestive of glioma or tumefactive demyelination. A subtotal resection was performed. Histopathology exhibited mature lymphocytes, plasma cells, and histiocytes with emperipolesis. Vessels showed transmural granulomatous inflammation. Fungal and mycobacterial stains were negative. Immunohistochemistry revealed positivity for CD68, S100, and CD1a. The patient refused to undergo postoperative adjuvant radiotherapy. He remained asymptomatic for 6 months but was lost to follow-up thereafter. RDD-LCH concurrence may represent a clonal transformation in a common precursor histiocyte. Coexistent GA requires resection followed by steroid or cyclophosphamide therapy to prevent disease progression.

Background and Aim: Postoperative radiotherapy with concomitant temozolomide (TMZ) followed by ≤ six cycles of adjuvant TMZ chemotherapy (Stupp regimen) is the standard treatment for newly diagnosed glioblastoma (GBM); however, its effectiveness is limited. Anlotinib inhibits both tumor angiogenesis and tumor cell proliferation by targeting multiple kinases, and showing promising results in preclinical GBM models. We designed a Phase II trial to assess the efficacy and safety of the Stupp regimen plus anlotinib. Methods/Design: This is a multicenter, double-blind, randomized, placebo-controlled trial with an expected 150 patients randomly assigned 1:1 ratio to receive TMZ-based radiochemotherapy with anlotinib (Stupp regimen + anlotinib) or placebo (Stupp regimen + placebo). Postoperative patient recruitment will begin in July 2021, the analysis of primary outcome measures will be completed in July 2023, and the study will finish in July 2024. Major eligibility criteria include histologically confirmed newly diagnosed GBM and an Eastern Cooperative Oncology Group performance score ≤2. Other criteria for inclusion include age ≥18 years and lack of significant comorbidity. In this study, the primary endpoint will be the median progression-free survival (PFS). Secondary endpoints include 1-year overall survival rate, PFS at 6 months, overall response rate, duration of response, disease control rate, quality of life, and toxicity. The protocol has received approval from Sun Yat-sen University Cancer Center Ethics Committee (Approval No. B2021-073-01; approved on April 19, 2021). Discussion: Updated treatment modalities are required for newly diagnosed GBM. Our proposed treatment modality of the Stupp regimen combined with anlotinib therapy are waiting conclusion. Trial Registration: This study was registered with ClinicalTrials.gov under identifier NCT04959500 on July 13, 2021.

Immunotherapy is typically ineffective against glioblastoma (GBM) due to inherent and adaptive resistance. Initial immunotherapy results for GBM have been disappointing. In this regard, T-cell exhaustion is a major barrier to successful treatment. The recognition of exhausted CD8+ T cell (Tex) pedigree is currently undergoing a paradigm shift. This review introduces major findings in this field to provide an up-to-date perspective on epigenetic, transcriptional, metabolic, and spatial heterogeneity, as well as interactions with tumor microenvironment cells of anti-tumoral CD8+ Tex from the following aspects: (i) Epigenetic and transcriptional mechanisms underlying T-cell exhaustion, (ii) Metabolic factors underpinning T-cell exhaustion, (iii) Contribution of multiple cell types to T-cell exhaustion, (iv) Occurrence of T-cell exhaustion at multiple locations, and (v) T-cell exhaustion may not always be terminal. These novel insights afford a wide range of new therapeutic approaches to overcome T-cell exhaustion in GBM.

Glioma is the most common brain tumor in the central nervous system and characterized by diffuse invasion into adjacent brain tissue. The extracellular matrix (ECM) is an essential component of the tumor microenvironment and it contributes to tumor progression through close interactions with glioma cells. Accumulated evidence has indicated that collagen levels, which are the most critical components of the ECM, are elevated in gliomas and collagen contributes to glioma progression. In this review, we provide a comprehensive summary of the roles of various collagens in glioma. A better understanding of the interactions of various collagens with glioma cells may provide new therapeutic strategies for gliomas.
