Abstract
OBJECTIVE Glioblastoma multiforme (GBM) following traumatic brain injury (TBI) is very rare and has not been comprehensively characterized by current literature. This systematic review aimed to characterize demographics of patients with post-TBI GBM. METHODS A systematic review of case studies and case series was conducted for reports published up to April 2023. All case reports that satisfied the criteria for diagnosing post-TBI GBM were included. The JBI case report appraisal was used to assess the quality of reporting of included articles. RESULTS Our review comprised 13 studies including 16 patients, most of whom were male (81%). Contusive TBI was the most frequent initial insult observed, with most patients requiring surgical intervention to manage TBI. The median latency between TBI and GBM diagnosis was 9.5 years with a negative correlation observed against patient age at TBI occurrence, but a positive correlation was noted for patients with IDH-wildtype GBM. Median age at GBM diagnosis was 56 years. CONCLUSIONS This systematic review highlights a possible link to GBM development at the previous TBI site. Updated criteria for identifying post-TBI brain tumors are proposed to keep abreast with the latest advances in classifying central nervous system tumors. To establish a definitive link, a large-scale international multicenter study investigating the occurrence of World Health Organization grade IV IDH-wildtype de novo GBM after TBI is crucial. Regular monitoring, especially in middle-aged and older patients with TBI, is advisable.

Abstract
Glioblastoma multiforme (GBM) is an aggressive variant of central nervous system gliomas that carries a dismal prognosis. Although GBM is the most frequently occurring and malignant type of glioma accounting for more than 60% of all brain tumors in adults, its overall incidence is rare, occurring at a rate of 3.21 per 100,000 persons. Little is known about the etiology of GBM, but one proposed theory is that GBM pathogenesis may be linked to a chronic inflammatory course initiated by traumatic injury to the brain. Limited case reports have suggested an association between GBMs and traumatic brain injury (TBI), but larger case-control and epidemiologic studies have been inconclusive. We present three service members (two active duty and one retired) who developed GBM near the original site of prior head trauma. Each service member's military occupation was in the special operations community and shared a common theme of TBI following head trauma/injury. The current research on the association between TBI and GBM is limited and conflicting, predominantly due to the low incidence of the disease in the general population. Evidence has indicated that TBI should be considered a chronic disease with long-term health impacts, including long-term disability, dementia, epilepsy, mental health conditions, and cardiovascular diseases. With the addition of our patients, as well as a recently published study proposing a molecular association between trauma and GBM, further research is needed to better understand the potential relationship.

Abstract
Despite their latent neurogenic potential, most normal parenchymal astrocytes fail to dedifferentiate to neural stem cells in response to injury. In contrast, aberrant lineage plasticity is a hallmark of gliomas, and this suggests that tumor suppressors may constrain astrocyte dedifferentiation. Here, we show that p53, one of the most commonly inactivated tumor suppressors in glioma, is a gatekeeper of astrocyte fate. In the context of stab-wound injury, p53 loss destabilized the identity of astrocytes, priming them to dedifferentiate in later life. This resulted from persistent and age-exacerbated neuroinflammation at the injury site and EGFR activation in periwound astrocytes. Mechanistically, dedifferentiation was driven by the synergistic upregulation of mTOR signaling downstream of p53 loss and EGFR, which reinstates stemness programs via increased translation of neurodevelopmental transcription factors. Thus, our findings suggest that first-hit mutations remove the barriers to injury-induced dedifferentiation by sensitizing somatic cells to inflammatory signals, with implications for tumorigenesis.

Abstract
Glioblastoma sometimes develops with acute onset due to intracerebral hemorrhage. Although it is sometimes difficult to diagnose patients with hemorrhagic-onset glioblastoma at the acute phase of intracerebral hemorrhage (ICH), the progressive enlargement of perifocal edema or the development of contrast-enhanced lesion triggers the diagnosis of glioblastoma within six months. Herein, we present a rare case of glioblastoma in which the diagnosis was delayed as long as 17 months after ICH. A 62-year-old man presented with a headache and aphasia. Computed tomography revealed ICH in the left temporal lobe. Magnetic resonance (MR) images revealed that the hematoma had a mix of isointense and surrounding hypointense lesions on T1-weighted MR images and gadolinium-enhanced lesions at the wall and the septum of the hematoma. An endoscopic evacuation of the hematoma was performed. No causative lesions were found during intraoperative and histological examinations. After seven months, abnormal signals were completely resolved on MR images, except for the small and stable enhanced lesion on three-dimensional gadolinium-enhanced T1-weighted MR imaging (3D Gd-T1WI) at the base of the hematoma, which did not change in size for seven months. However, a large gadolinium-enhanced lesion at the left temporal lobe developed 17 months after ICH. He underwent total resection of the lesion and was diagnosed with glioblastoma. He received radiation therapy and temozolomide but died of disseminated recurrence 31 months after ICH. In conclusion, this report presents a didactic case of glioblastoma in which the diagnosis of glioblastoma was delayed 17 months after ICH whereas hemorrhagic-onset glioblastoma was previously considered ruled out in cases in which six months or more have passed after ICH. In order not to overlook these cases, follow-up with 3D Gd-T1WI is essential in the case of suspected tumor-related ICH and close follow-up is recommended when the enhanced lesion does not resolve after a long period even if it does not grow.

Abstract
BACKGROUND Traumatic brain injury (TBI) as a pathogenetic factor in glioma remains controversial, and currently there is still no clear mechanism behind post-TBI glioma. Thus, we provide two case reports of post-TBI glioma contributing power to this research, and we provide a summary of the mechanisms of post-TBI glioma through literature review. METHODS We report two cases of brain gliomas that developed in the scar of a previous brain trauma. Both patients were male and both had suffered prior traumatic brain injuries (time interval 10-20 years), and postoperative pathological findings reported glioblastoma and WHO grade III glioma, respectively. RESULTS These two cases further support the association of between traumatic brain injury and gliomas development. CONCLUSION Although the epidemiological investigation between TBI and glioma is still controversial, there are still some important aspects here that can determine the possibility between TBI and gliomagenesis. Besides, we found that the reparative response of neural stem cells and the dysregulation of inflammatory cells are timportant theories of the mechanism of post-TBI glioma.

Abstract
A 48-year-old man presented with headaches and confusion. Imaging demonstrated a right frontal glioblastoma multiforme (GBM), twenty years after a nail gun injury to the same region. GBM in the same location as a previous injury points toward possible causation from the trauma in the development of a high-grade glioma.

Abstract
The role of prior head trauma in stimulating brain tumor development has been previously described in the literature but continues to be debated. The goal of this study was to conduct a systematic review interrogating the contemporary literature to delineate any possible relationship between traumatic brain injury and brain tumor development. A systematic review exploring development of post-TBI brain tumor was conducted by searching electronic databases. Abstracts from articles were read and selected for full-text review according to criteria previously established in the scientific literature. Relevant full-text articles were divided into case reports and single-arm studies and epidemiological studies. Of 1070 resultant articles, 18 case reports and single-arm studies (level of evidence of IV and V) with 45 patients were included. The most common cause of TBI was traffic accidents. The average period between TBI and subsequent tumor diagnosis was 12.8 years. Meningiomas represented the largest share of tumors, followed by gliomas. Most post-TBI brain tumors developed in the frontal and temporal lobes. Fifteen epidemiological studies were also interrogated from a variety of countries (level of evidence of III). Case-control studies were more common than cohort studies. There were 9 of 15 studies proposed a possible relationship between history of head trauma and development of brain tumor. The relationship between head trauma and neoplastic growth continues to be heavily debated. There are certainly case reports and epidemiological studies in the literature that suggest a correlational relationship between the two. However, there is no concrete evidence of a causal relationship between TBI and brain tumors. More research is needed to definitively delineate the extent of any such relationship.

Abstract
Traumatic brain injury (TBI) was first proposed as a potential risk factor for developing a glioma in the 1800s, and conditions for establishing a causal relationship between brain injury and gliomas have since been proposed. Given the medical and legal ramifications, the current literature was reviewed to better understand this possible association. Articles that examined the relationship between TBI and glioma formation in adults and were published in English between 1978 and 2022 were reviewed. There were 19 case reports of 25 patients and 16 observational studies. The case reports describe glioma formation at the precise site of prior brain injury in continuity with traumatic scar; the observational studies report conflicting findings, but they largely demonstrate no association. Most of the observational studies are limited by their retrospective nature, but we identified one prospective cohort study which found a positive association. Altogether, we suggest that glioma formation after TBI is a rare occurrence that warrants further study.

Abstract
The role of traumatic brain injury in the development of glioma is highly controversial since first presented. This is not unexpected because traumatic brain injuries are overwhelmingly more common than glioma. However, the causes of post-traumatic glioma have been long discussed and still warrant further research. In this review, we have presented an overview of previous cohort studies and case–control studies. We have summarized the roles of microglial cells, macrophages, astrocytes, and stem cells in post-traumatic glioma formation and development, and reviewed various carcinogenic factors involved during traumatic brain injury, especially those reported in experimental studies indicating a relationship with glioma progression. Besides, traumatic brain injury and glioma share several common pathways, including inflammation and oxidative stress; however, the exact mechanism underlying this co-occurrence is yet to be discovered. In this review, we have summarized current epidemiological studies, clinical reports, pathophysiological research, as well as investigations evaluating the probable causes of co-occurrence and treatment possibilities. More efforts should be directed toward elucidating the relationship between traumatic brain injury and glioma, which could likely lead to promising pharmacological interventions towards designing therapeutic strategies.

Abstract
Canada has one of the highest incidence rates of brain cancer in the world. This study investigates the space–time variation of brain cancer risk across Southern Ontario, Canada. A Bayesian spatio-temporal regression model is used to estimate the relative risk of brain cancer in the 12 spatial health units of Southern Ontario over a four-year period (2010–2013). This work also explores the association between brain cancer and two potential risk factors: traumatic head injury (THI) and excess body fat (EBF). Across all areal units from 2010–2013, results show that the relative risk of brain cancer ranged from 0.83 (95% credible interval (CI) 0.74–0.91) to 1.26 (95% CI 1.13–1.41). Over the years, the eastern and western health units had persistently higher risk levels compared to those in the central areas. Results suggest that areas with elevated THI rates and EBF levels were also potentially associated with higher brain cancer relative risk. Findings revealed that the mean temporal trend for cancer risk progression in the region smoothly decreased over time. Overall, 50% of the health units displayed area-specific trends which were higher than the region’s average, thus indicating a slower decrease in cancer rates for these areas in comparison to the mean trend.

Abstract
OBJECTIVE Abscess formation within a glioblastoma has been reported rarely. In the few reported cases, after aspiration to treat a presumed abscess, lesions recurred over a short period and, consequently, glioblastoma was recognized. We present a case of a glioblastoma that developed 1.5 years after successful treatment of a brain abscess. A latency of 1.5 years before symptom development seems overly long, even if the glioblastoma was present at the time of the initial brain abscess. Hence, we consider this a possible de novo glioblastoma arising from glial scar tissue. We also discuss possible mechanisms underlying malignant transformation. CASE DESCRIPTION A 78-year-old man was admitted to our hospital with progressive gait disturbance caused by a brain abscess. Aspiration of the cyst and systematic antibiotic therapy cured the abscess. However, 1.5 years later, the patient presented to our hospital with generalized convulsions due to recurrence of the cystic lesion. He underwent craniotomy for removal of the cystic lesion, which was found to be a glioblastoma rather than a recurrent brain abscess. Glial scar tissue was detected in the cyst wall. CONCLUSIONS Development of glioblastoma after treatment of a brain abscess is rare; the pathogenesis is open to speculation. Based on the clinical course, the pathologic findings, and comparison with previous reports, de novo glioblastoma arising from glial scar tissue may be the most likely explanation of the current case. If so, to our knowledge, this is the first report of this condition.

Abstract
Several radiation-related professional societies have concluded that carcinogenic risks associated with doses below 50-100 mSv are either too small to be detected, or are nonexistent. This is especially important in the context of doses from medical imaging. Radiation exposure to the public from medical imaging procedures is rising around the world, primarily due to increased utilization of computed tomography. Professional societies and advisory bodies consistently recommend against multiplying small doses by large populations to predict excess radiation-induced cancers, in large part because of the potential for sensational claims of health impacts which do not adequately take the associated uncertainties into account. Nonetheless, numerous articles have predicted thousands of future cancers as a result of CT scanning, and this has generated considerable concern among patients and parents. In addition, some authors claim that we now have direct epidemiological evidence of carcinogenic risks from medical imaging. This paper critically examines such claims, and concludes that the evidence cited does not provide direct evidence of low-dose carcinogenicity. These claims themselves have adverse public health impacts by frightening the public away from medically justified exams. It is time for the medical and scientific communities to be more assertive in responding to sensational claims of health risks.

Abstract
BACKGROUND Neoplastic transformation of damaged astrocytes has been proposed as a possible pathological mechanism behind malignant astrocytic tumors. This study investigated the association between structural brain injuries causing reactive astrogliosis and long-term risk for malignant astrocytic tumors. METHODS The cohort consisted of all individuals living in Denmark between 1978 and 2011. The personal identification number assigned to all individuals allowed retrieval of diagnoses of traumatic brain injury, cerebral ischemic infarction, and intracerebral hemorrhage from the National Patient Discharge Register. Diagnoses of anaplastic astrocytoma and glioblastoma multiforme (World Health Organization grades III and IV) were retrieved from the Danish Cancer Registry. Rate ratios (RR's) were estimated using log-linear Poisson regression. RESULTS In a cohort of 8.2 million individuals, 404 812 experienced a structural brain injury and 6152 developed a malignant astrocytic tumor. No significant association was observed 1-4 years after a structural brain injury (RR = 1.14; 95% CI: 0.87-1.46), whereas the long-term (5+ y) risk for malignant astrocytic tumors was significantly reduced (RR = 0.68; 95% CI: 0.49-0.90) compared with no injury. The specific long-term risks by type of injury were: traumatic brain injury RR = 0.32 (95% CI: 0.10-0.75); cerebral ischemic infarction RR = 0.69 (95% CI: 0.47-0.96); and intracerebral hemorrhage RR = 1.39 (95% CI: 0.64-2.60). CONCLUSION We found no evidence for an association between structural brain injury and malignant astrocytic tumors within the first 5 years of follow-up. However, our study indicated a protective effect of astrogliosis-causing injuries 5 or more years after structural brain injury.

Abstract
To add a further contribution to the literature supporting the relationship between previous head trauma and the development of glioma. We present the first case of pregnancy-related post-traumatic malignant glioma in a 29-year-old female who was admitted because of left sided hemiplegia and epilepsy due to a malignant glial tumor. She had been operated for a right frontal hematoma caused by a motorbike accident 9 years before. Neuroimaging showed a large neoplasia in the right frontal region beneath the material used for cranialplasty, and postoperative pathological revealed a glioblastoma multiforme (GBM) in continuity with the scar resulting from the trauma. While epidemiologic studies may not be conclusive, a pathologic basis has been suggested which show that trauma act as a cocarcinogen in the presence of an initiating carcinogen. Our case fulfilled the widely established criteria for brain tumors of traumatic origin. We believe that in specific cases it is reasonable to acknowledge an etiological association between head trauma and glioma. And additional factors such as pregnancy may promote the manifestation of the clinical symptoms.

Abstract
This population-based study in Taiwan aimed to investigate the risk of having a diagnosis of malignant brain tumors within 3 years after a traumatic brain injury (TBI). This study used data from the Traumatic Brain Injury Registry and the National Health Insurance Research Database. The study cohort comprised 5007 patients who had visited ambulatory care centers or had been hospitalized with a diagnosis of TBI between 2001 and 2002. The comparison cohort was 25,035 randomly selected enrollees. Each patient's brain cancer status was individually tracked for a 3-year period following their index date. Stratified Cox proportional hazards regressions were performed for analyses. During the 3 years of follow-up, nine patients in each cohort, both the TBI and the non-TBI cohort, were diagnosed with brain cancer. As compared to those patients without TBI, patients with TBI were more likely to receive a diagnosis of malignant brain tumors within the 3-year period following their index date: the incidence rate of malignant brain tumors was 6.28 (95% CI: 3.06-11.53) per 10,000 person-years in patients with TBI and 1.25 (95% CI: 0.61-2.29) per 10,000 person-years in patients without TBI. After adjusting for sociodemographic characteristics, the hazard of being diagnosed with malignant brain tumors during the 3-year follow-up period was 4.67 (95% CI: 1.84-11.83) times greater for those who sustained a TBI than for patients in the comparison cohort. In addition, we found an association between TBI severity and malignant brain tumor among patients with TBI (p=0.033). Our findings suggest a positive correlation between TBI and the relatively short-term development of malignant neoplasms of the brain.
