“…The mean age at diagnosis was 45.54 years in our study which is higher than that of other studies in Iran [ 21 , 23 – 27 ] and Jordan [ 19 ] but is lower than that of other developed countries which seems to be related to population structure changes. The preponderance of males among CNS tumour patients in our study is in accordance with the global estimates in 2012 (1.41 compared with 1.2 m/f ratio) [ 31 ] and the estimates in most of other studies in the world that represent male to female ratios between 1 and 2.7 [ 35 ]; however, some studies showed female predominance similar to Qom province [ 19 , 22 , 46 ]. The possible hypothesis for male preponderance is sex hormones and adverse working conditions such as exposure to chemicals and pesticides [ 47 ].…”

Background. Central nervous system (CNS) tumours account for only 1-2% of cancer incidence but are a major reason for mortality and morbidity due to malignancies. Recent studies show an increase in the rate of CNS tumours worldwide, especially in developing countries. Moreover, there is significant heterogeneity in epidemiological patterns worldwide. This study is aimed at representing nationwide epidemiology of CNS tumours in Iran. Methods. Iran National Cancer Registry 2010-2014 data were reviewed for CNS tumours. The epidemiological rates were calculated for both genders and all age groups using the 2011 census information. Results. Out of 17345 cases, 58.5% were men and 41.5% were women. The mean age was 45.55 years ranging from less than 1 month to 100 years old. Average total age-standardized incidence rate (ASR) was 5.19 for primary tumours. The annual percent change (APC) was 14.23% during the study period. The most frequent site and histology recorded were brain, NOS and diffuse astrocytic, respectively. Geographical distribution showed about five-fold difference in ASRs between different provinces. Conclusion. The overall ASR calculated was higher than the global rate in 2012 but lower than that of most developed countries, showing an increasing trend which may be due to either advances in diagnosing or risk factor augmentation. The mean age and incident rates were higher than those of previous reports in Iran.

“…According to data collected from the Bulgarian population, the annual incidence of ICTs is 8.85 people per 100,000, comprised of 6.03 per 100,000 for primary ICTs and 2.82 for metastatic ICTs [ 34 ]. Furthermore, in other European populations, the reported incidence is even higher than the reported figures in our studies [ 3 ].…”

“…Nowadays the scientific research of intracranial tumors (ICTs) attracts numerous scientific teams and tremendous financial resources worldwide [ 1 - 3 ]. These lesions of the central nervous system (CNS) and structures located in the cranial cavity can be both benign and malignant in biological behavior as well as local or metastatic in origin for malignant lesions [ 4 - 6 ].…”

Intracranial tumors (ICTs) attract numerous scientific teams and tremendous financial resources worldwide. These lesions of the central nervous system (CNS) can be both benign and malignant in biological behavior as well as local or metastatic in origin. We compared data from two studies on primary and metastatic ICTs from Brazil and Bulgaria, based on histopathologically confirmed ICTs from tertiary health centers. Primary ICTs significantly outweigh the frequency of metastatic ICTs. Primary ICTs represent 86.45% in Brazil and 69.17% in Bulgaria, with around 60% of their totals being malignant. There is a statistical dominance of tumors from the neuroepithelial origin, with the most common entry being glioblastoma multiforme. The second-most common primary ICT group comprises tumors of meningeal origin. Metastatic ICTs show great variance; 13.55% in Brazil and 31.38% in Bulgaria of all ICT cases being attributed to them. However, metastatic ICTs are even a more diverse group than neuroepithelial tumors, with the majority of this group comprising metastatic colorectal adenocarcinoma (almost exclusively in males), metastatic breast adenocarcinoma in females, metastatic pulmonary carcinomas (primarily from the non-small cell group with a male predominance), and metastatic melanoma with an even gender ratio.

“…The carboplatin/etoposide regimen was used when the Temozolamide was not available. The survival pattern of our population joins the other populations in several points such as the slight better outcome for women compared to men 6,25 , the decrease survival with increasing age 6,11 , and increasing grade of malignancy 14,19 and survival of GBM 17,[26][27][28] . Nonetheless, the minor fluctuations observed when comparing the cohort to others become more accentuated when it comes to the OS (mean = 45.4 months, median = 21.7, survival rates at 1-, 2-, and 5-years of 62.8%, 48.5% and 32.9% respectively) found to be higher than the European (1-and 5-years survival = 56.9% and 19.6%, respectively) and the Tunisian (mean = 27 months, 1-, 2-and 5-years survival rates : 42%, 30% and 26% respectively) 6,11,14,17,19,26 .…”

Background: Gliomas are a relatively rare group of tumors with a poor prognosis. We aimed to describe and analyze the clinical characteristics and survival of patients with glioma tumors of Eastern Algeria. Methods: A retrospective study was conducted at the University Hospital of Constantine. Medical records of patients enrolled between January 2008 and October 2016 were consulted. Demographic characteristics, clinical data, treatment strategy and dates of last follow-up or death were collected. Chi-square test was used for checking associations, Kaplan- Meier methodology for estimating the survival, and the cox model for identifying prognosis factors. Results: A total of 333 patients composed our cohort. The mean age was 48.07 years, and men were 1.87 times more frequent than women. High grade tumors were mainly observed among adults and old adults and in supra-tentorial locations. More than half of the patients had a large resection and a curative protocol of oncological treatment (50.7% and 57%, re- spectively). The mean overall survival was 45.4 months, the median was 21.7 months, and survival rates at 1-, 2-, and 5-years were: 62.8%, 48.5% and 32.9% respectively. Age, histology, grade of malignancy and oncological treatment were the major prognosis factors. Conclusion: Our sample was relatively young with a higher survival compared to others.
