Epidemiology of Primary CNS Tumors in Iran: A Systematic Review

Clinicopathological Findings and Five Year Survival Rates for Patients with Central Nervous System Tumors in Yazd, Iran

“…In our study the tumor frequency was higher in the male population compared to the female population and this was in coherence with other studies (Mao et al, 1991;Parkin et al, 2001;Jazayeri et al, 2013). They documented a higher frequency of cancer in the male population.…”

“…In the study reported by Manoharan et al (2012) the most frequently tumor types were gliomas (25.4%), glioblastomas (21.5%) and astrocytomas (20.6%), that was similar to our study, despite, they didn't studied the benign tumors prevalence such as meningioma. In a systematic review by Jazayeri et al (2013) the most common forms of tumor were Astrocytoma and Glioblastoma multiform (15.2% and 13.8%, respectively). In the study published by cancer research UK.…”

Glioma Epidemiology in the Central Tunisian Population: 1993-2012

“…In previous study, the Central nervous system tumor incidence is higher among male than female (M/F=1.4) (Jazayeri et al, 2013). Similarly, in glial tumor the male to female crude rates ratio is ranged between 1.4 for astrocytic tumors and to 1.3 for the oligodendroglial (Crocetti et al, 2012) In European population, there are about 26,610 new diagnosed glial tumors per year during 1995-2002.…”

Clinical Manifestations and Imaging Characteristics of Gliomatosis Cerebri with Pathological Confirmation

“…High incidences of tumors of the brain and nervous system have been noted in Brazil, the US and the Hawaiian islands among the white population, Canada , Italy Poland, Finland an other European countries, and low incidence was found in Africa and Asia (Cheng et al, 2013;Igissinov et al, 2013;Jazayeri et al, 2013;Liang et al, 2013;Zeybek et al, 2013;Zhang et al, 2013). GC is a special kind of tumor of CNS, for which invasive growth is its typical biological behavior and the key factor of high reoccurrence rate and short survival time.…”
