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.

Anatomical changes in resection cavity during brain radiotherapy
ConclusionRCs are dynamic after surgery. Potentially, an additional margin in brain cancer patients with an RC should be considered, to avoid insufficient target coverage. Future research on local recurrence patterns is recommended. (Source: Journal of Neuro-Oncology)

Preoperative assessment of eloquence in neurosurgery: a systematic review
ConclusionsThere were major differences in the definitions and assessment methods of eloquence, and none of them proved to be satisfactory to express eloquence as an objective, quantifiable, preoperative factor to use in glioma decision making. Therefore, we propose the development of a novel, objective, reliable, preoperative classification system to assess eloquence. This should in the future aid neurosurgeons in their preoperative decision making to facilitate personalized treatment paradigms and to improve surgical outcomes. (Source: Journal of Neuro-Oncology)

Ganciclovir as a potential treatment for glioma: a systematic review and meta-analysis
ConclusionsThis meta-analysis showed that ganciclovir significantly improved the prognosis of glioma patients. Therefore, we suggest that more cases of ganciclovir as a glioma treatment can be conducted, or a large clinical trial can be designed. (Source: Journal of Neuro-Oncology)

Focused ultrasound combined with radiotherapy for malignant brain tumor: a preclinical and clinical study
ConclusionReirradiation is becoming an option after disease recurrence for both primary and secondary malignant brain tumors since systemic therapy significantly prolongs survival in cancer patients. The mechanism behind the synergistic effect of RT-FUS in preclinical model needs further study. The clinical evidence from the interim analysis of an ongoing clinical trial (NCT01628406) showed a combination of RT-FUS was safe (no FUS-related adverse effect). A comprehensive analysis of radiation dosimetry and FUS energy distribution is expected after completing the final recruitment. (Source: Journal of Neuro-Oncology)

RFX2 promotes tumor cell stemness through epigenetic regulation of PAF1 in spinal ependymoma
ConclusionsRFX2 activates PAF1 transcription, which promotes tumor stemness of SE cells and leads to the malignant progression of SE. (Source: Journal of Neuro-Oncology)

Management strategies for intracranial progression in ALK-positive non-small cell lung cancer: a real-world cohort study
ConclusionThe intracranial progression-free survival showed no difference between the two strategies suggesting that both local radiotherapy and systemic therapy may be valid options. Individualized strategy, molecular analysis, and multidisciplinary conferences may all play a pivotal role in decision-making. (Source: Journal of Neuro-Oncology)

Treatment of very elderly glioblastoma patients  ≥ 75 years of age: whom to treat
ConclusionFor very elderly patients, the natural course of disease without treatment is devastating. These patients benefit from multimodal treatment including adjuvant radiotherapy and chemotherapy. A beneficial effect of resection has not been demonstrated. Treatment options and outcomes should be thoughtfully discussed before treatment decisions are made. (Source: Journal of Neuro-Oncology)

Targeted immunotherapy for glioblastoma involving whole tumor-derived autologous cells in the upfront setting after craniotomy
AbstractPurposeTo date, immunotherapeutic approaches in glioblastoma (GBM) have had limited clinical efficacy as compared to other solid tumors. Here we explore autologous cell treatments that have the potential to circumvent treatment resistance to immunotherapy for GBM.MethodsWe performed literature review and assessed clinical outcomes in phase 1 safety trials as well as phase 2 and 3 autologously-derived vaccines for the treatment of newly-diagnosed GBM. In one recent review of over 3,000 neuro-oncology phase 2 and phase 3 clinical trials, most trials were nonblinded (92%), single group (65%), nonrandomized (51%) and a...

A multi-site phase I trial of Veliparib with standard radiation and temozolomide in patients with newly diagnosed glioblastoma multiforme (GBM)
ConclusionsAlthough Veliparib 10  mg BID administered with TMZ 75 mg/m2 for six weeks was well tolerated, when this regimen was combined with standard partial brain irradiation it was severely myelosuppressive even when the dose was reduced by 50%. This study again highlights the potential of localized cranial radiotherapy to sig nificantly increase hematologic toxicity of marginally myelosuppressive systemic therapies.

Pyruvate kinase M2 (PKM-2) expression and prognostic significance in glioblastoma patients
ConclusionPKM2 is an independent prognostic factor for survival and is associated with poor prognosis in GBM patients treated with radiotherapy. It may be a potential therapeutic target for anticancer therapy. (Source: Journal of Neuro-Oncology)

Generation of patient-derived pediatric pilocytic astrocytoma in-vitro models using SV40 large T: evaluation of a modeling workflow
ConclusionA subset of primary PA cultures can be converted into long-term cell lines using SV40-TAg depending on sample intrinsic (patient age) and extrinsic workflow-related (e.g. type of medium, successful transduction) parameters. Careful monitoring of sample-intrinsic and extrinsic factors optimizes the process. (Source: Journal of Neuro-Oncology)
