Correlations between histological subtypes and neurocognitive assessment of language area tumors. Our 43 case series and review of the literature.
CONCLUSIONS: A neurocognitive assessment of brain tumor patients is important for preoperative and postoperative evaluation and secondary adjustment of the surgical resection in order to improve or, at list, meantime the initial status. The role and the link between the histological type and tests alteration were observed. The results can be used for a better understanding and management of language area tumors.

ConclusionMapping during resection of gliomas located in or near the perirolandic area and descending motor tracts can be safely carried out with both AC and GA.
ConclusionsAwake craniotomy with mapping has become the gold standard for safely maximizing extent of resection for tumor in or near eloquent brain. Cortical and subcortical mapping methods have been refined and the technique is associated with an extremely low rate of complications.

Buttrick, Angela Richardson, Christopher Sarkiss, Michael E. Ivan, Ricardo J. KomotarAbstractWith a recent trend towards supra-maximal resection for gliomas and minimally invasive techniques, keyhole temporal lobectomies may serve an important role in neurosurgical oncology. Due to their location and proximity to eloquent brain, temporal lobe gliomas offer unique challenges that may limit the extent of resection. Here we describe a mo...
In this study, we used Magnetoencephalography (MEG) to investigate functional connectivity changes in peritumoral and contra-tumoral regions after brain tumor resection. MEG recordings of cortical activity during resting-state were obtained from 12 patients with LGGs in left-hemisphere language brain areas. MEG data were recorded before (Pre session), and 3 (Post_1 session) and 6 (Post_2 session) months after awake craniotomy. For each MEG session, we measured the functional connectivity of the peritumoral and contra-tumoral regions to the rest of the brain across the 1-100 Hz frequency band. We found that functional ...
CONCLUSIONS: UPF1 is down-regulated in glioma and alleviates the progression of glioma via targeting CYTOR. PMID: 31799670 [PubMed - in process]
ConclusionsThe literature is rich in cases related to the use of DTI in brain tumors, the results are excellent if one thinks of the saving of functionally important brain areas. Therefore, the excision of malignant tumors such as gliomas and glioblastomas is followed by a different and better outcome and a different quality of life. DTI tractography today represents the best and safest way of preserving the superior cortical functions in brain tumor surgery.
A patient presented with visual changes raising suspicion of progression of underlying brain cancer requiring craniotomy. Final results showed Nocardia farcinica brain infection instead. Nocardiosis should be considered in patients receiving corticosteroids as management can be lifesaving.
ConclusionsIn our technical report, we demonstrate that combining intraoperatively fluorescein sodium and IOUS improves the information and facilitates making decisions during the HGG surgery. Further experience gained in larger studies will help confirm these findings
We describe the relationship between preoperative plasma lactate levels, and the cell proliferation marker Ki-67 in brain tumor surgery. METHODS: In this cross-sectional study, records of patients who underwent craniotomy between June 2017 and February 2018 at our Hospital were reviewed to select glioma and meningioma cases in which lactate concentrations in plasma and degree of cell proliferation were registered. Bivariable and linear regression analyses were used to assess the association between lactate concentrations and the Ki-67 index. RESULTS: Lactate concentrations in plasma and Ki-67 index were available i...
ConclusionsThe current series add some hints to the poorly studied IOS risk during awake surgery. The risk of IOS appears to be relatively higher in patients with anteriorly located tumors and in patients operated without intraoperative brain activity monitoring and different patterns of stimulation for language and sensory-motor mapping. Further studies are needed to clarify the role of intraoperative techniques.
