BACKGROUND Tumor epidemiology is a significant part of CNS (central nervous system) tumor studies. Reassessment of original sections can update our knowledge of tumor spectrum. Here, we discuss the features of CNS tumor pathology in a single center. METHODS A total of 34140 cases from 1950 to 2009 were collected; sections from 1990 to 2009 were reassessed according to WHO 2007 classification,...

Germ-line and acquired mutations of the hSNF5/INI1 tumor suppressor gene have been reported in central nervous system (CNS), renal, and soft-tissue rhabdoid tumors. The present study was designed to compare the types of INI1 alterations among tumors from diverse anatomical sites and identify mutation hot spots. Fluorescence in situ hybridization and PCR-based microsatellite, heteroduplex, and s...

primary and secondary malignant central nervous system (cns) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. glioblastoma multiform (gbm), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced dna damage repair program that also induces recurrence and resists current chemo- and radio...

BACKGROUND Central nervous system (CNS) tumors are the most common cause of cancer-related death in children. Little is known about the demographics and treatment of pediatric brain tumors in low- and middle-income countries (LMICs). METHODS We performed a retrospective chart review of all pediatric patients who presented to the neurosurgical service at Tribhuvan University Teaching Hospital ...

Crush preparation cytology technique was used during the operative procedure for the diagnosis of 199 CNS tumors. This technique is simple, easy to perform, rapid, and inexpensive. The cytomorphologic findings were excellent and helped achieve a rapid and correct diagnosis. This technique was used on the tiny, small specimens which were not suitable for frozen sectioning. The results were c...

Despite numerous studies over the past three decades, the role of these markers in the diagnosis of central nervous system (CNS) tumors is not yet established. In this report, the literature is reviewed and an attempt is made to define the usefulness of CSF biochemical markers for detecting primary and metastatic CNS neoplasms, with emphasis on the potential of these markers for the early ident...
