Objective: To analyze the features of isocitrate dehydrogenase 1 (IDH 1) mutation in 165 oligodendroglial tumors.
Methods: IDH1 was detected in a series of 165 oligodendroglial paraffin specimens from 2009 to 2011. And their features were analyzed.
Results: Mutant IDH1 was detected in 111 (67.3%) tumors including 109 (98.2%) CGT→CAT mutations, 1 (0.9%) CGT→AGT mutation and 1 (0.9%) CGT→TGT mutation. The frequencies of IDH mutation in AO, O and OA were 13/15, 83.3% and 72.9% respectively. They were significantly higher than that in AOA (27.0%, P < 0.001).
Conclusion: The different frequencies of IDH1 mutation in different subsets of oligodendroglial tumors may imply varied tumorigenic pathways between subsets.

Unlabelled: QUESTIONS AND RECOMMENDATIONS FROM THE PRIOR VERSION OF THESE GUIDELINES WITHOUT CHANGE: TARGET POPULATION: Adult patients (age ≥ 18 years) who have suspected low-grade diffuse glioma.
Question: What are the optimal neuropathological techniques to diagnose low-grade diffuse glioma in the adult?
Recommendation: Level I Histopathological analysis of a representative surgical sample of the lesion should be used to provide the diagnosis of low-grade diffuse glioma. Level III Both frozen section and cytopathologic/smear evaluation should be used to aid the intra-operative assessment of low-grade diffuse glioma diagnosis.

Background: Brain tumors exhibit diverse genetic landscapes and hemodynamic properties, influencing diagnosis and treatment outcomes.
Purpose: To explore the relationship between MRI perfusion metrics (rCBV, rCBF), genetic markers, and contrast enhancement patterns in gliomas, aiming to enhance diagnostic accuracy and inform personalized therapeutic strategies. Additionally, other radiological features, such as the T2/FLAIR mismatch sign, are evaluated for their predictive utility in IDH mutations.

Cholangiocarcinoma is an aggressive bile duct malignancy with heterogeneous genomic features. Although most patients receive standard-of-care chemotherapy/immunotherapy, genomic changes that can be targeted with established or emerging therapeutics are common. Accordingly, precision medicine strategies are transforming the next-line treatment for patient subsets.

Background: Isocitrate dehydrogenase (IDH) inhibitors hold promise for IDH-mutated cancer patients and demonstrated favorable clinical efficacy. Nonetheless, a comprehensive understanding of the associated toxicities of IDH inhibitors remains notably lacking.
Research Design And Methods: This pharmacovigilance analysis utilized the FDA Adverse Event Reporting System (FAERS) database to assess notable adverse events (AEs) attributed to IDH inhibitors (enasidenib and ivosidenib) from January 2018 to December 2023.

Outcomes of myeloproliferative neoplasms (MPN)-associated acute leukaemias are dismal with conventional therapy. Approximately 20% of MPN-associated acute leukaemias have mutations in isocitrate dehydrogenase (IDH). Olutasidenib, and inhibitor of IDH1, demonstrates important clinical benefits in MPN-associated leukaemia with IDH1 mutation.
