MGMT promoter methylation in 1p19q-intact gliomas
ConclusionsThis ancillary analysis supports conclusions from the CATNON trial for adjuvant TMZ as standard-of-care for anaplastic astrocytomas (IDH-mutant and 1p19q-intact), irrespective ofMGMT status. Determining the optimal strategy for diffuse gliomas that are IDH-wildtype will be particularly important.MGMT promoter methylation should be considered as a stratification factor in future clinical trials for these patients.

Cancers, Vol. 16, Pages 43: Congenital Tumors & mdash;Magnetic Resonance Imaging Findings with Focus on Rare Tumors
Cancers, Vol. 16, Pages 43: Congenital Tumors—Magnetic Resonance Imaging Findings with Focus on Rare Tumors Cancers doi: 10.3390/cancers16010043 Authors: Kwasniewicz Wieczorek-Pastusiak Romaniuk-Doroszewska Bekiesinska-Figatowska Congenital tumors are rare and, owing to this rarity, there is limited information on many of them. A total of 839 fetal and postnatal MRI studies performed in the first 3 months of life were retrospectively reviewed. They were performed with the use of 1.5 T scanners. Seventy-six tumors were diagnosed based on fetal MRI between 20 and 37 gestational weeks, and 27 were ...

Individualized discrimination of tumor progression from treatment-related changes in different types of adult-type diffuse gliomas using [11C]methionine PET
ConclusionThis work confirms that MET PET has varying diagnostic performances in distinguishing TP from TRCs within three types of adult-type diffuse gliomas, and highlights its high diagnostic accuracy inIDH-mutant and 1p/19q-codeleted oligodendroglioma and potential prognostic value forIDH-mutant gliomas, particularlyIDH-mutant astrocytoma.

Fluorescence-guided resection of intradural spinal tumors: a systematic review and meta-analysis
AbstractIntradural spinal tumors present significant challenges due to involvement of critical motor and sensory tracts. Achieving maximal resection while preserving functional tissue is therefore crucial. Fluorescence-guided surgery aims to improve resection accuracy and is well studied for brain tumors, but its efficacy has not been fully assessed for spinal tumors. This meta-analysis aims to delineate the efficacy of fluorescence guidance in intradural  spinal tumor resection. The authors performed a systematic review in four databases. We included studies that have utilized fluorescence agents, 5-aminolevulinic acid (...
