The authors present a rare of prenatally diagnosed congenital anaplastic astrocytoma. A 9-month-old boy had three recurrences despite two surgical resections and various chemotherapeutic regimens. He underwent the 3rd gross tumor removal at 11 months of age, followed by proton therapy, and now he remains disease-free for 3 yr without a significant neurocognitive dysfunction. This is the 1st cas...

We report a case of a 44-years-old woman with relapsing-remitting and secondarily progressive form of multiple sclerosis (MS) since aged 24 years, who developed an anaplastic astrocytoma. The neurological manifestations of the tumor were misinterpreted as resulting from MS. Sequential MRI examination and seizures raised the possibility of another nature of her symptoms, besides MS. Her initial ...

Background & Objectives: The accurate assessment of the diseased tissue is fundamental to the diagnosis and management of disorders of the central nervous system (CNS). The ‛squash’ or ‛crush’ technique has been universally employed in the intraoperative diagnosis of CNS tumors. The aim of our study was to evaluate the accuracy of squash preparation in diagnosing CNS tumors by comparing with hi...

PURPOSE To review our experience with pre-radiation chemotherapy for malignant glioma. METHODS Consecutive adults with newly diagnosed glioblastoma, anaplastic astrocytoma, anaplastic oligodendroglioma and anaplastic mixed glioma with a Karnofsky Performance Score of 60 or greater were treated with one cycle of procarbazine, lomustine and vincristine or lomustine alone, prior to radiation. Co...

Thirty-two cases of surgically removed astrocytoma were evaluated for the expression of androgen receptors(ARs) immunohistochemically and the relationships between androgen receptors, DNA ploidy pattern, and survival of patients were studied. The cases included 18 grade I/II astrocytomas, 4 anaplastic astrocytomas, and 10 glioblastoma multiforme(GBM). Positive AR was present in 12 out of 32 cas...

Loss of constitutional heterozygosity for specific chromosomal loci, »henfound consistently in a particular tumor type, suggests that a recessive oncogene important in the genesis ofthat tumor may be present within the involved chromosomal loci. DNA markers that detect restric tion fragment length polymorphisms are powerful tools that have been used to detect loss of chromosomal loci in a grow...

A 54-year-old man presented with a very rare case of radiation-induced intramedullary spinal cord anaplastic astrocytoma, which developed 37 years after radiotherapy for testicular seminoma. The patient presented with weakness and numbness of the left lower extremity that had gradually aggravated for 3 months. Magnetic resonance imaging demonstrated an intramedullary mass lesion with syringomye...

PURPOSE The purpose of this research was to investigate the relationship between glutathione S-transferase (GST) polymorphisms and survival, and chemotherapy-related toxicity in 278 glioma patients. EXPERIMENTAL DESIGN We determined genetic variants for GSTM1, GSTT1, and GSTP1 enzymes by PCR and restriction fragment length polymorphisms. We conducted Kaplan-Meier and Cox-proportional hazard a...

Neurologically, BRAF V600E mutation was detected in cerebellar anaplastic pilocytic astrocytoma [6], ganglioglioma [7], desmoplastic infantile astrocytoma [8], indeterminate cell tumor and interdigitating dendritic cell sarcoma [9]. Hematologically, BRAF V600E mutation was also detected in multiple myeloma [10] and several leukemias (hairy cell, chronic lymphocytic, prolymphocytic and acute lym...

To further understand the biological significance of amplifications for glioma development and recurrencies, we characterized amplicon frequency and size in low-grade glioma and amplicon stability in vivo in recurring glioblastoma. We developed a 12q13-21 amplicon-specific genomic microarray and a bioinformatics amplification prediction tool to analyze amplicon frequency, size, and maintenance ...
