In the United States, the 5-year survival rate for patients of all ages with all types of brain tumors is approximately 20%, with the scale skewed toward even poorer survival in patients with gliomas. Although surgery and radiotherapy are primary treatment options, surgery is rarely curative and radiotherapy has had little impact on overall survival. Predominantly studied in adults with advance...
Background :Brain metastasesfromprimarycervical cancer are very rare.Wepresentthis report, to describe a case of brainmetastasesfromprimaryuterine cervical and conduct literaturereview about clinicalpresentation, treatment, prognosis thisdesease. Case Presentation :A 51-year-old woman, followed since 2017 for squamous cell carcinoma the cervix which she had underwent surgical treatment received...
PURPOSE To evaluate the prognostic factors associated with overall survival in patients with brain metastasis treated with whole brain radiotherapy (WBRT) and estimate the potential improvement in survival for patients with brain metastases, stratified by the Radiation Therapy Oncology Group (RTOG) recursive partitioning analysis (RPA) class. PATIENTS AND METHODS From January 1996 to December...
Treatment of glioblastoma multiforme (GBM) and brain metastasis remains a challenge because of the poor survival and the potential for brain damage following radiation. Despite concurrent chemotherapy and radiation dose escalation, local recurrence remains the predominant pattern of failure in GBM most likely secondary to repopulation of cancer stem cells. Even though radiotherapy is highly eff...
Conventional MRI studies showed that radiation-induced brain necrosis in patients with nasopharyngeal carcinoma (NPC) in years after radiotherapy (RT) could involve brain gray matter (GM) and impair brain function. However, it is still unclear the radiation-induced brain morphological changes in NPC patients with normal-appearing GM in the early period after RT. In this study, we acquired high-...
normal 0 false false false en-us x-none ar-sa radiation therapies are commonly used for malignant or metastatic brain tumors for curative and palliative use. the radiation-induced neurotoxicity includes both parenchymal and vascular damage. here we report the case of a 43-year-old woman who developed multiple sclerosis (ms) 9 months after she underwent the last session of radiotherapy for the d...
Background : To assess feasibility of sparing the neural stem cell compartment (NSC), hippocampus, and limbic circuit during partial brain radiotherapy (PBRT) for pediatric intracranial tumors. Methods : Treatment plans were generated for the following pediatric intracranial tumors: low and high grade gliomas, low grade brainstem glioma, optic nerve glioma, hypothalamic glioma, localized ependy...
