“…We suspect that the cause may be multifactorial. It should be noted, however, that a similar discrepancy was reported before between the incidence of malignant tumours in developed and developing countries [15], furthermore even in some European countries incidence rates of primary intracranial tumours in a range between 8.5-14 per 100,000 were reported [8,16,17]. The active case ascertainment method used in our study does not exclude influences of several factors, which may result in missing of brain tumours cases.…”

“…In a light of the rarity of brain tumours, the focus on malignant brain tumours does not enhance systematic and detailed epidemiological data identification. Six-fold differences in the incidence of primary brain tumours have been reported in literature between countries worldwide and developed countries appear to have the highest rates of brain tumours, but the relevant studies from registries in developing countries are scarce [6][7][8][9][10] .…”

Primary brain tumour epidemiology in Georgia: first-year results of a population-based study

et al. 2013

A population-based cohort study was initiated in Georgia in March 2009 to collect epidemiologic data of malignant and non-malignant primary brain tumours. During the first year, 473 incident cases were identified. For a population of 4.3 million, the annual incidence rate was 10.25 per 100,000 inhabitants, age-standardized to the year 2000 US population. Non-malignant tumours constituted about 66 % of all tumours. Males accounted for 40 % and females for 60 % of the cases. Crude incidence rates by histology were highest for meningiomas (2.92/100,000), pituitary adenoma (1.16/100,000) and glioblastomas (0.64/100,000), which was in agreement with the frequency of reported histology: meningiomas-45.2 %, pituitary adenoma-18.0 % and glioblastomas-9.9 %. The age-standardized incidence rates were higher among females than males for all primary brain tumours (11.05 vs. 8.44/100,000) as well as for individual histologies except for glioblastoma and several other neuroepithelial tumours. Some differences compared with 2004-2005 Central Brain Tumor Registry of the United States data may be explained by a higher percentage of unclassified tumours (37 %) in our study. We suggest further studies to clarify the nature of this discrepancy.

“…The majority of the studies were based on United States registry data. A European study was also included, but had limited data for 264 patients, including numerous types of intracranial tumors, therefore the incidence rate has reduced validity and it may be problematic to interpret the results (11). The European study also presented the number of patients in terms of incidence rate that was not age-adjusted and, subsequently, the results are not be able to be compared with the other studies reducing the validity of the findings (11).…”

“…Two studies used data exclusively from the United States and one study investigated data from a Croatian population. The incidence rates from these previous studies ranged from 0.13-0.5 per 100,000 for male patients and 0.09-0.1 per 100,000 for female patients between 1996 and 2010 (Table II) (4,5,11).…”

“…The remaining 11 studies included information on high-grade tumors and are reviewed in the current study. However, all studies that included incidence rate data on ependymal tumors did not separate anaplastic ependymoma from other ependymal tumor types and, therefore, these results were not included in the analysis (Table I) (4,5,10,11). Similarly, as the studies that included choroid plexus tumors did not differentiate choroid plexus carcinoma from lower grade tumor types, these results were also not included (4,5).…”

Incidence trends in high-grade primary brain tumors in males and females

et al. 2017

View full text Add to dashboard Cite

Abstract. The focus of the present review is to investigate whether there is a variation in the incidence rates between male and female patients with high-grade primary brain tumors and if there are altered incidence rates associated with the time at which they were diagnosed. Previous studies identified in internationally peer-reviewed journals were identified using a systematic search of the PubMed database. Due to the difficulties in data interpretation, studies that exclusively included patient data classified prior to the 2nd edition of the World Health Organization histological classification system of brain tumors were excluded. The overall incidence rates and incidence trends of male and female patients were analyzed separately. The mean age-adjusted overall incidence rate in the male population was 1.27 per 100,000 compared with 0.89 per 100,000 in the female population. The variance between the two genders differed and a Wilcoxon rank-sum test indicated that there was no significant difference in the incidence rate of high-grade primary brain tumors between males and females (P= 0.3658). Furthermore, there was no significant difference in incidence rate trend between 1996-2004 and 2005-2010 for male or female populations (P=0.101 and P=0.472, respectively). The results from the present systematic review did not demonstrate a significant difference in incidence rate between the two genders. Therefore, the results from the current study are considered to be preliminary and further studies are required to elucidate this issue.
