Epidemiology of brain tumors in the United Arab Emirates: a National Registry Cross-sectional Study
BMC Neurology, 2020
Background Cancer is the third leading cause of death in the United Arab Emirates (UAE); brain cancer ranks 10th among the cancers, with 2.9% of the primary cancers originating from the nervous system. The epidemiology of brain cancers has not been explored. The unique population dynamics of UAE make it a fertile ground for analyzing the epidemiology of brain cancer. In this study, we aim to look at the frequency patterns and distribution of malignant primary brain tumors in the UAE. Methods A cross sectional study was carried out using data obtained from the Tawam Hospital Cancer Registry for the years 1984–2017. The sample size included 756 diagnosed cases of malignant primary brain tumors in the UAE. Using SPSS and Excel software, frequencies, mean ages, histological type frequencies, average annual crude incidence rates and average annual age adjusted incidence rates were analyzed. Results The expatriate population had higher percentage of brain tumors (72%) than the locals. The...

Background: Brain tumors are associated with marked disability and mortality. Understanding the patterns and epidemiological characteristics associated with brain tumors can be crucial to their treatment. Objective: To explore the magnitude and epidemiological features of primary brain tumors among patients admitted to Aseer Central Hospital (ACH), Abha City, Saudi Arabia, and to identify different decisions for their management. Methodology: All hospital records of brain tumor patients admitted to ACH from 2015-2017 were reviewed. Collected data included patients' demographic characteristics, clinical findings, histopathological diagnosis, and management. Results: During the aforementioned period, a total of 100 patients with primary brain tumors were admitted to ACH. The most commonly presenting symptoms were headache (72%), vomiting, dizziness, and focal motor deficits (25% for all). Tumor location was mostly at the frontal or parietal lobes. Among those who underwent surgery, meningioma grade I was the most frequently diagnosed (41.7%). The mean surgical time was 4.2 ± 1.6 h. Most patients who underwent surgery at ACH stayed in the intensive care unit anywhere from 1 d or 2-4 d (34% and 40%, respectively). The Glasgow outcome scale scores of most patients (91.7%) indicated that the patients had a good recovery. However, one patient died (1.7%), one was in a persistent vegetative state (1.7%), and three sustained moderate disability (5%). Conclusion: Most patients with brain tumors admitted to ACH undergo surgery. Meningioma grade I is the most commonly encountered brain tumor, and this finding may reflect different epidemiological findings from the internationally accepted concept that glioblastoma multiforme is the most common brain tumor. The most common locations for brain tumors are the frontal and parietal lobes.
Epidemiology of Malignant and Non-Malignant Primary Brain Tumors in Jordan
Neuroepidemiology, 2015
There is lack of knowledge on the epidemiological characteristics of brain tumors in Middle Eastern countries. The objective of this study was to study the epidemiological features of primary brain tumors in Jordan. We conducted a prospective cohort study incorporating data from 16 hospitals in Jordan during a 1 year period (May 1, 2011-April 30, 2012). All primary brain tumors diagnosed in Jordan during the study period were identified. The following parameters were retrieved from patients' files: age, gender, histological type, and location. The demographic data of the country was obtained from the National Department of Statistics. A total of 313 primary brain tumors were identified during the study period. The incidence of primary brain tumors in Jordan among the general population was 5.01 per 100,000 person-years (5.38 in females and 4.65 in males). The incidence in pediatric, adult, and elderly patients was 2.09, 7.29, and 14.38 per 100,000 person-years, respectively. The...

with a diagnosis of primary CNS tumor (brain and spinal cord) were selected. Data about sex, age, tumor location, and histologic type were collected. The classification was based on the International Classification of Diseases for Oncology, 3rd Edition (ICD-O-3). Results. Nine hundred and ninety-two (992) cases of primary CNS tumors throughout the ten years (2005 to 2014) were reviewed. There were 714 (71.97%) adults and 278 (28.02%) in the pediatric age group. Nonmalignant tumors dominated the adult population (60.08%) while malignant tumors were more frequent in the pediatric population. Gliomas constituted the most common neoplastic category in children and adults. The most common single tumor entity was meningioma (26.99%, ICD-O-3 histology codes 9530/0, 9539/1, and 9530/3). Medulloblastomas (ICD-O-3 histology codes 9470, 9471, and 9474) were the most common single tumor entity in the pediatric age group (26.62%). Conclusions. This is an institution-based, detailed, and descriptive epidemiological study of patients with primary CNS tumors in Saudi Arabia. In contrast to other regional and international studies, the medulloblastomas in our institution are more frequent than pilocytic astrocytomas. Limitations to our study included the referral bias and histology-based methodology.

OBJECTIVES Central nervous system (CNS) tumors are a major and growing global healthcare challenge. Western Saudi Arabia has an inconsistent data registry; therefore, the epidemiology of CNS tumors is unclear across the country. This study is aimed to assemble the epidemiological matrix of CNS tumors in the Western Province of Saudi Arabia. METHODS A retrospective analysis was performed using clinical data obtained from 3 neuroscience centers in Western Saudi Arabia in the period 2014-2019. The sample size included 663 adult and pediatric cases from the local and expatriate populations diagnosed with CNS tumors. The distributions of age, sex, clinical presentation, tumor location, type of surgery, histological subtype, genetic characteristics, and recurrence rate were explored. RESULTS The analysis included 500 adult cases and 163 pediatric cases up to 18 years of age with a male-to-female ratio of 1.16. The mean age at diagnosis was 38.0±22.6 years. The supratentorium was the most ...

Introduction: Tumors are the second-most common cause of death after cardiovascular diseases. Due to the high prevalence and mortality rate, brain tumors are of great importance and makeup about 5% of all tumors. Different types of brain tumors have their special pattern based on age, sex, complaints on admission, radiological signs and sometimes, their family history and seem these patterns are changing according to the geographic region over time. In this study, we evaluate the incidence of brain tumors in the northwest of Iran. Materials and Methods: All patients with brain tumor diagnosis that were hospitalized between April 2011 and March 2016 evaluated. Exclusion criteria were considered as secondary tumors of the central nervous system (CNS) (metastases) and duplicate records for the recurrent disease of the same patient. Data collected from their documents and analyzed with SPSS version 16. Results: In the present study, male to female (M: F) ratio is 1:1. 92.5% of tumors are primary in which meningiomas (22%) and glioblastoma multiforme (GBM) (19.6%) are the most common types. The rarest tumor types are neurocytoma (0.3%) and chondroid chordoma (0.3%). GBM is the most common tumor in the male population and meningiomas are most common in females. Medulloblastoma and meningioma with a median age of 11 and 58 years, respectively, were known as the most common primary CNS malignancy of the youngest and oldest age of study group. Conclusion: The obtained data from this study revealed that age and sex are associated with the tumor types, which is consistent with the previous results. Brain tumors involvement pattern is changing in male patients somehow there is a tendency of involving more aggressive and malignant tumor types in male individuals could be seen.
Epidemiology of primary brain tumors in the Middle Eastern population in California, USA 2001–2005
Cancer Detection and Prevention, 2009
Background: The fast growing Middle Eastern (ME) population has rarely been studied in the U.S.. The purpose of this study was to compare the epidemiology of primary brain tumors in this ethnic population with the non-Hispanic, non-Middle Eastern White (NHNMW) in California. Methods: ME cases were identified by surname in the California cancer registry and ME population estimates were based on ancestry. Data for 683 cases of primary brain tumors (429 benign, 238 malignant, 16 uncertain) in the ME and 15,589 cases (8352 benign, 6812 malignant, 425 uncertain) in the NHNMW were available for this study. Results: ME patients were significantly ( p < 0.05) younger and their age-adjusted incidence rates per 100,000 for benign tumors of 10.0 in men and 17.6 in women were higher than similar rates of 7.3 and 10.6 in the NHNMW group ( p < 0.05). Rates for malignant tumors were similar. Meningioma was the main histology responsible for the observed increase in patients over 40 years of age. Also increased were benign tumors of the pituitary and pineal glands. The overall mortality in patients with benign tumors was significantly lower than malignant tumors. Conclusions: This study presents a significantly high incidence of benign meningioma in the ME population in California. This may be due to higher susceptibility or exposure of this ethnic group to the risk factor(s) for this neoplasm. Considering the reported causal association of benign meningioma with childhood radiation exposure from Israel, exposure to this risk factor in this ethnic group needs to be evaluated in future studies. #

This retrospective study comprehensively analyses the epidemiological trends of Central Nervous System (CNS) cancers in Saudi Arabia over three decades, from 1990 to 2019. Utilizing data from the Institute for Health Metrics and Evaluation (IHME) and the Saudi Cancer Registry, the study examines incidence, prevalence, and mortality rates, offering a detailed depiction of CNS cancer trends in the region. The findings reveal a significant increase in the incidence of CNS cancers, with rates increasing from 1.1 to 3.63 per 100,000 population. Despite this rise, the incidence in Saudi Arabia remains lower than in more developed regions, suggesting regional variations in risk factors and healthcare practices. The study observes a marked decline in mortality rates, from 25% in 1990 to below 10% in 2019, indicative of the effect of advancements in early detection, molecular diagnostics, and therapeutic interventions. Gender disparities were apparent, with males exhibiting higher incidence and mortality rates, aligning with global epidemiological patterns. The study also highlights demographic variability in CNS cancer incidence, with a prominent increase in adult populations, particularly those aged 55 and above. These findings underscore the need for targeted public health strategies and healthcare policies to address the rising incidence and improve patient outcomes. The study advocates for future research focusing on the etiology of CNS cancers, particularly in genetic and environmental factors, and calls for international collaboration in research to understand global variations in CNS cancer trends.
Objectives: to describe the pattern of metastatic brain tumors (MBT) at King Abdulaziz University Hospital (KAUH) over the 6 years and Correlate the clinical data and treatment options with the survival rate. Design: retrospective study. Results: 66 patients were reviewed. Overall, the most common MBT was bronchogenic carcinoma. The mean age was 57.7±15.7 years. The survival was affected negatively in correlation with tumor multiplicity (P <.014), numbness (P <.0001), abnormal vision (P <.001) and seizure (P <.00005). The survival was improved by radiotherapy alone (P <.001). Conclusions: Several clinical risk factors may affect the survival of MBT patients.
