Central neurocytoma (CN) is a rare and elusive tumor. The relationship between clinical outcome, tumor nature, treatment of CN remains controversial. There were eight patients in our hospital from 2014 to 2021, the prevalence accounted for 0.36% brain tumors. All them underwent surgical removal, two combined with adjuvant radiotherapy (RT). We found that four without complications had small tum...

The World Health Organization (WHO) classification of central nervous system (CNS) tumors incorporates morphology, cytogenetics, molecular genetics, and immunologic markers. Despite the relatively large number of CNS tumors with clonal chromosome abnormalities, only few studies have investigated cytogenetic abnormalities for CNS tumors in Korea. Thus, we investigated 119 CNS tumors by conventio...

BACKGROUND AND PURPOSE In a subset of in vivo MR spectra acquired from pediatric brain tumors, we have observed an unassigned peak. The goal of this study was to determine the molecule of origin, and the prevalence and concentration of this chemical in various pediatric brain tumors. MATERIALS AND METHODS Single-voxel point-resolved spectroscopy (PRESS) spectra from 85 patients with brain tum...

    Background: Contrary to adults, primary and metastatic involvement of CNS is a rare condition in pediatric malignant tumors. With CNS involvement the prognosis will be poor and practical treatment modalities will decline so new approaches must be reviewed. The aim of this study was to find out the incidence of CNS involvement in different childhood malignancies. Also the survival analysis w...

The incidence rate of central nervous system tumors in the USA is 14.8/100,000 people per year.1 Within these, the malignant CNS tumors are accountable for at least 12,760 deaths for the year 2005 (1). The CNS tumors incidence in the USA is associated with male gender, Caucasian race, metropolitan area residents, and the elderly population (2). CNS tumor incidence in the USA has been studied an...

OBJECTIVE Few studies exist on the demographics and trends of pediatric central nervous system (CNS) tumors in Iran. In this study, we retrospectively reviewed all cases with confirmed CNS tumors admitted to Mofid Pediatric Hospital, Tehran, Iran during the last 18 years. MATERIALS & METHODS Data on gender, age of diagnosis, pathologic classification and tumor location were extracted from the...

Traditionally, patients who die with a malignancy have been excluded from donation. However, it has become a common practice to accept organs from donors that have low-grade tumors or tumors with low metastatic potential. The aim of this study was to analyze our experience with the use of liver grafts from donors with central nervous system (CNS) tumors. A retrospective review of 1173 liver tra...
