    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Childhood; CNS tumour; pilocytic astrocytoma; posterior fossa; long-term outcome; cognition; language; motor performance; learning difficulties; Pediatrik; Pediatrics;

    Abstract : Introduction: Pilocytic astrocytoma is the most common brain tumour in childhood. The aim of the studies was to investigate late medical, cognitive and motor complications in patients treated in childhood for pilocytic astrocytoma in the posterior fossa. READ MORE

  4. 2. Gene expression studies in human astrocytoma, with emphasis on oncostatin M induced effects

    Author : Annika Krona; Göteborgs universitet; []
    Keywords : Brain tumors; astrocytoma; glioblastoma multiforme; oncostatin M OSM ; STAT; microarray;

    Abstract : Brain tumors comprise about one percent of all cancers and astrocytoma is the most common primary brain malignancy. According to the World Health Organization system, the astrocytomas are divided into four grades according to degree of malignancy. Grade I, pilocytic astrocytoma (PA), is the least malignant form and most often affects children. READ MORE

  5. 3. Transcription factors PROX1 and p53 in cancer development

    Author : Tamador Elsir; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The majority of malignant brain tumors in adults are astrocytic gliomas. These are classified into four malignancy grades according to the World Health Organization (WHO) criteria, including grade I pilocytic astrocytoma, grade II astrocytoma, grade III anaplastic astrocytoma and grade IV glioblastoma.

  6. 4. Oncogenes and tumour suppressor genes in human central nervous system tumours

    Author : Lu Liu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Human central nervous system (CNS) tumours may arise from both developing and adult brain. Primitive neuroectodermal tumours (PNETs) are the most malignant tumours arising from developing brain, and constitute approximately one third of brain tumours in children. Other common paediatric CNS tumours are ependymomas and pilocytic astrocytomas. READ MORE

  7. 5. lmproving diagnosis of central nervous system tumours using genetic and epigenetic tools

    Author : Thomas Olsson Bontell; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Histopathology; DNA methylation profiling; DNA methylation-based classification; Diffuse lower grade-glioma; Genomic analysis; Molecular biomarkers; Pediatric glioma;

    Abstract : Brain tumor diagnostics has traditionally been based on histopathology stains. The introduction of immunohistochemistry stains resulted in improved ability to classify these often devastating tumors. The understanding of molecular markers in central nervous system tumors has improved substantially in recent decades. READ MORE
