2. 1. Genes and brain tumors

   Author : Maral Adel Fahmideh; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Although brain tumors are rare and combined with other nervous system tumors account for ~ 2% of all cancers, they are the second most common type of pediatric cancer. The etiology of brain tumors, known as multifactorial traits, is poorly understood. READ MORE

4. 2. A path along deep learning for medical image analysis : With focus on burn wounds and brain tumors

   Author : Marco Domenico Cirillo; Anders Eklund; Veronika Cheplygina; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deep learning; Medical image analysis; Burn wounds; Brain tumors; Image classification; Image segmentation; Image augmentation; CNNs; GANs;

   Abstract : The number of medical images that clinicians need to review on a daily basis has increased dramatically during the last decades. Since the number of clinicians has not increased as much, it is necessary to develop tools which can help doctors to work more efficiently. READ MORE

5. 3. Proton Magnetic Resonance Spectroscopy in Brain Tumors - Clinical Applications

   Author : Isabella Björkman-Burtscher; Lund Diagnostisk radiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; Localization; Abscess; Brain; Tumor; Spectroscopy; Magnetic Resonance; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Abstract : Aims: · to present a test phantom and test method for evaluation of proton magnetic resonance spectroscopy (1H-MRS) single volume localization techniques regarding signal contamination; · to describe the introduction of 1H-MRS in the daily routine of a standard MR-unit; · to evaluate the possibilities offered by 1H-MRS to improve preoperative diagnostic accuracy in patients scheduled for stereotactic biopsy of intracranial mass lesions; · to evaluate the possibilities offered by 1H-MRS to improve diagnostics and therapy control in patients with brain abscesses; · to test the hypothesis that 1H-MRS might be useful for differentiation of brain tumors, based on metabolic changes in tissue across brain lesions or surrounding tissue. Results and conclusions: · The test phantom and test method allow quality assessment with good reproducibility. READ MORE

6. 4. Experimental brain tumors, dendritic cells and immunotherapy

   Author : Shorena Janelidze; Neurokirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dendritic cell; interferon-γ; immunotherapy; Brain tumor;

   Abstract : Malignant astrocytomas are the most common primary tumors of the adult central nervous system. Surgical resection of tumor mass in combination with radiotherapy and chemotherapy is only palliative and there is a clear need for new and more effective therapeutic strategies. READ MORE

7. 5. Immunotherapy and COX-2 inhibition against malignant brain tumors

   Author : Sofia Eberstål; Neurokirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Malignant brain tumors; immunotherapy; IFN-γ; GM-CSF; COX-2 inhibition;

   Abstract : Glioblastoma multiforme (GBM) is the most common primary brain tumor in the central nervous system and the prognosis is very poor despite conventional therapies including surgery, chemo- and radiotherapy. Peripheral vaccination with irradiated tumor cells represent a novel therapy that targets both dividing and non-dividing tumor cells and minimizes the risk of therapy resistance by presenting multiple tumor antigens.
