چکیده
PRIMARY BENIGN and malignant brain tumors are common and occur with an incidence of 12.8 cases per 100,000 according to the Central Brain Tumor Registry of the United States. The relative incidence of brain tumors is age dependent. Intracranial neoplasms, or new tissue growths, represent the most common solid tumors in children younger than age 15. In this age group, primary tumors of the nervous system comprise approximately 20% of all cancers, making them the second most common form of childhood cancer after leukemias.

Glioma is the most common type of brain tumor and according to the 2016 WHO classification, based on invasion level, it is divided into four categories. The most severe and invasive type is grade IV glioma or glioblastoma (GBM), which has a very poor prognosis and a survival rate of only 15 months. However, the molecular pathway of invasion in malignant glioma tumors has not yet been clearly el...

متن کاملAnalysis of Exon 19 and 39 of ATM Gene in Brain Tumors; Considering the P53 Accumulation
Many studies have been focused on cytogenetic and molecular genetic defects in brain tumors; therefore the role of ATM as a tumor suppressor gene in these tumors is poorly considered. In this study mutation analysis of exon 19 and 39 of ATM gene and P53 accumulation were investigated by PCR-SSCP, sequencing, and flow cytometry . Four polymorphisms including D1853N, IVS 38-8 T?C, F858L, P872T we...
