Cognitive effects of tumour and surgical treatment in glioma patients.
Quality of life in brain tumour patients is an emerging issue and has prompted neurosurgeons to reconsider the need for cognitive assessment in the course of treatment. In particular, to date there has been a lack of comprehensive neuropsychological assessment performed preoperatively and in the acute postoperative period. We examined 29 patients with glioma, analysing several functional domains-intelligence, executive functions, memory, language, praxis, gnosis and mood state-in order to establish the effect of tumour and surgery on cognition. ⋯ Worsening regarded executive functions was related to tumour size and was partly explained by radiological findings on postoperative magnetic resonance imaging (MRI). This preliminary study, focussing on the effects of tumour and surgery, showed that tumour significantly affects cognitive functions, mainly due to the mass effect and higher grading. Surgical treatment improved the functions most frequently affected preoperatively and caused worsening of executive functions soon after operation, leaving the overall cognitive burden unchanged and capable of improvement prospectively.

A study of patients with brain metastases as the initial manifestation of their systemic cancer in a Chinese population.
To investigate the clinical characteristics of patients with brain metastases as the initial manifestation of their systemic cancer in a Chinese population, a retrospective study of 254 such patients admitted to Huashan Hospital, Fudan University, Shanghai, China between January 1, 2003 and December 30, 2008 was performed. Data were collected to determine the features of this group (i.e., manifesting signs and symptoms, imaging studies, extracerebral metastases, primary tumor sites, initial diagnosis, and survival data). Common symptoms included headache and motor impairment. ⋯ Adenocarcinoma was the most common histologic type. Given the high frequency of primary lung tumors and the sensitivity of chest CT, chest CT should be a part of the initial screen of primary site with brain metastases as the initial manifestation. Metastatic dissemination of malignancy to the brain as the initial manifestation is generally associated with dismal prognosis, with the exception of a minority who experience long survival.

Ventriculoperitoneal shunt complications in hydrocephalus patients with intracranial tumors: an analysis of relevant risk factors.
Patients with intracranial tumors are predisposed to persistent hydrocephalus, often requiring a permanent CSF diversion procedure with shunts. This study reviews the long-term experience with ventriculoperitoneal shunts for the management of hydrocephalus in patients with intracranial tumors. Patients with intracranial tumors who underwent ventriculoperitoneal shunt placement for hydrocephalus from October 1990 to October 2009 were included in this study. ⋯ The overall incidence of shunt revision was 27.8%. Age, tumor histology, and a procedure prior to shunt placement (ventriculostomy/Ommaya reservoirs) were significantly associated with the shunt revisions. Additional studies using minimally invasive techniques are being explored for the management of hydrocephalus in patients with intracranial tumors.

Review Case ReportsSupratentorial and cerebellar liponeurocytomas: report of four cases with review of literature.
Liponeurocytoma is not exclusive to the cerebellar or fourth ventricular location. Since its inclusion in the central nervous system tumor classification in 2000, six cases with similar radiological, histomorphological and immunohistochemical features have also been described in the lateral ventricles. In the present study, we report clinical, radiological and pathological findings of three supratentorial and one cerebellar liponeurocytoma from our records, evaluated with an extensive panel of immunohistochemistry, and review published cases in the literature. The immunohistochemical pattern of supratentorial and infratentorial liponeurocytomas are almost identical, which indicates that these tumors are homologous.

Correlation between O6-methylguanine-DNA methyltransferase and survival in elderly patients with glioblastoma treated with radiotherapy plus concomitant and adjuvant temozolomide.
Epigenetic silencing of the O(6)-methylguanine-DNA-methyltransferase (MGMT) gene by promoter methylation is correlated with improved progression-free survival (PFS) and overall survival (OS) in adult patients with newly diagnosed glioblastoma multiforme (GBM) who receive alkylating agents. The aim of this study is to determine the correlation between MGMT and survival in elderly patients with GBM treated with radiotherapy (RT) and temozolomide (TMZ). Eighty-three patients aged 70 years or older with histologically confirmed GBM treated with RT plus TMZ between February 2005 and September 2009 were investigated in this study. ⋯ Median PFS was 10.5 months in methylated tumors and 5.5 months in unmethylated tumors (P = 0.0001). On multivariate analysis MGMT methylation status emerged as the strongest independent prognostic factor for OS and PFS (P = 0.004 and P = 0.005, respectively). The results of the present study suggest that MGMT methylation status might be an important prognostic factor associated with better OS and PFS in elderly patients with GBM treated with RT and TMZ.
