Case Reports Multicenter StudyMalignant spinal cord compression in cerebral glioblastoma multiforme: a multicenter case series and review of the literature.
Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor in adults. Compared with other malignancies, remote metastases in GBM are rare. However, multicentric spreading within the central nervous system is common and also metastases to the spinal cord have been reported. ⋯ Multicentric cerebral distribution and subependymal enhancement of GBM are observed on cerebral MRI at the time of MSCC. On the basis of our results, no specific treatment recommendations for MSCC in GBM patients can be given. However, accurate diagnosis of MSCC in GBM patients with spinal signs and symptoms can lead to adequate management of symptoms and improvement of quality of life in terms of best palliative care.

Patterns of care and outcomes of patients with pleomorphic xanthoastrocytoma: a SEER analysis.
To study the clinical characteristics, treatment approach and outcome of pleomorphic xanthoastrocytoma (PXA), patients were identified using the National Cancer Intitute's Surveillance, Epidemiology, and End Results (SEER) database. A total of 214 patients were identified with PXA using the November 2010 submission. Patient demographics, tumor characteristics, extent of surgical resection, the use of radiotherapy, and overall survival were evaluated. ⋯ The role of radiation therapy for PXA remains unclear but is more often used for patients with high grade tumors. Compared to other common brain tumors, PXA's appear to fare worse than pilocytic astrocytoma and oligodendroglioma, especially in younger patients. However, even high grade PXA patients have significantly better overall survival compared to glioblastoma.

Spatial brain distribution of intra-axial metastatic lesions in breast and lung cancer patients.
The frequency of the diagnosis of brain metastases has increased in recent years, probably due to an increased diagnostic sensitivity. Site predilection of brain lesions in oncological patients at the time of onset, may suggest mechanisms of brain-specific vulnerability to metastasis. The aim of the study is to determine the spatial distribution of intra-axial brain metastases by using voxel-wise statistics in breast and lung cancer patients. ⋯ It was found that the lesions were more likely to be located in the parieto-occipital lobes and cerebellum for the total cohort and for the non small cell lung cancer group, and in the cerebellum for the breast cancer group. The voxel-wise inter-group comparisons showed the largest significant clusters in the cerebellum for the breast cancer group (p < 0.0008) and in the occipital lobe (p = 0.02) and cerebellum (p = 0.02) for the non small cell lung cancer group. We conclude a non-uniform distribution of metastatic brain lesions in breast and lung cancer patients that suggest differential vulnerability to metastasis in the different regions of the brain.

Decision-making abilities in patients with frontal low-grade glioma.
Decisions in daily life are often quite complex, especially when one has to decide about his/her own health, as it is the case for patients with brain tumours. The integrity of the prefrontal cortex (and of the orbito-frontal in particular) is crucial in humans for practical decision-making. We investigated decision-making in 22 right-handed patients with a left frontal low-grade glioma, by means of a more complex, computerized version of the Iowa gambling task and we compared their performance with that of 26 neurologically-unimpaired subjects. ⋯ In both groups, level of comprehension, significantly affected performance. An improvement was found post-surgery. In conclusion, the performance in the Gambling Task suggests that patients with left frontal low-grade gliomas can be impaired in decision-making, apparently requiring more time to understand the task: therefore, a particular attention and care should be taken to explain risks and consequences of his/her illness and treatment in order to obtain an informed decision from the patient.

The influence of surgery on quality of life in patients with intracranial meningiomas: a prospective study.
Meningiomas may influence both survival and neurological functions. Studies assessing the impact of surgery on health-related quality of life (HRQL) remain absent. In this prospective study we aimed to describe HRQL dynamics before and after surgery in patients with meningiomas. ⋯ About half of the patients reported a clinical important improvement at the late follow-up assessment. This improvement was mainly observed in the domains usual activities, pain/discomfort and anxiety/depression. However, one in five patients fared worse on late follow-up assessment, a figure of particular importance when treating asymptomatic meningiomas.
