Shanta M. Messerli Central nervous system atypical teratoid/rhabdoid tumors (ATRTs) are rare and aggressive tumors with a very poor prognosis. Current treatments for ATRT include resection of the tumor, followed by systemic chemotherapy and radiation therapy, which have toxic side effects for young children. Gene expression analyses of human ATRTs and normal brain samples indicate that ATRTs have aberrant expression of epigenetic markers including class I histone deacetylases (HDAC’s) and lysine demethylase (LSD1). Here, we investigate the effect of a small molecule epigenetic modulator known as Domatinostat...

Authors: Nakashima K, Demura Y, Oi M, Tabata M, Tada T, Shiozaki K, Akai M, Ishizuka T Abstract We herein report a 66-year-old woman with advanced lung adenocarcinoma (PD-L1 tumor proportion score 60%) lacking driver oncogenes in whom meningeal carcinomatosis, along with sudden onset dizziness, deafness, and consciousness disturbance, appeared after second-line chemotherapy. Whole-brain radiation therapy (WBRT) and Pembrolizumab were subsequently administered, and third-line chemotherapy with Pembrolizumab is now ongoing. At the time of writing, the patient has achieved a 23-month survival without disease progressi...

Abstract Cranial radiation therapy (CRT) remains to be the foundation stone of the management of brain metastases in non-small cell lung cancer (NSCLC). Nevertheless, the care of NSCLC, recently, has been remarkably reshaped by the immune checkpoint inhibitors (ICIs), such as programmed death protein-1 and programmed death ligand-1 inhibitors, which even showed some efficacy in brain metastases. Furthermore, radiotherapy, traditionally regarded as a therapy via localized cytotoxicity, recently was reported to trigger a systemic immune response, thus probably enhancing the antitumor effect of ICIs. Preliminary data...

Brock Fuller Chung Glioblastoma is an aggressive brain tumor with a propensity for intracranial recurrence. We hypothesized that tumors can be visualized with diffusion tensor imaging (DTI) before they are detected on anatomical magnetic resonance (MR) images. We retrospectively analyzed serial MR images from 30 patients, including the DTI and T1-weighted images at recurrence, at 2 months and 4 months before recurrence, and at 1 month after radiation therapy. The diffusion maps and T1 images were deformably registered longitudinally. The recurrent tumor was manually segmented on the T1-weighted image and then app...

Conclusions: The study of MRT is concentrated in brain-related diseases performed mostly in rat models. An appropriate comparison between MRT and conventional radiotherapy (instead of synchrotron broad beam) is needed. Recommendations are provided for future studies involving MRT.

ConclusionFurther clinical trials are necessary to improve the identification of suitable patient cohorts and the extent of possible volume de-escalation that does not compromise tumor control.

In this study, we examined the mitochondrial-mediated mechanisms involving TMZ-induced neural damage in primary rat neural stem/progenitor cells (NSC) and hippocampal neurons. TMZ inhibited mtDNA replication and transcription of mitochondrial genes (ND1 and Cyt b) in NSC by 24 h, whereas the effect of TMZ on neuronal mtDNA transcription was less pronounced. Transmission electron microscopy imaging revealed mitochondrial degradation in TMZ-treated NSC. Acute TMZ exposure (4 h) caused a rapid reduction in dendritic branching and loss of postsynaptic density-95 (PSD95) puncta on dendrites. Longer TMZ exposure impaired mitocho...

CONCLUSIONS: Significant differences exist in PBT use by demographics and health insurance type. The identified racial and socioeconomic disparities merit further investigation. More granular studies on both use patterns and effectiveness of PBT for specific cancers are needed to draw stronger conclusions about its cost-benefit ratio. PMID: 32059097 [PubMed - in process]
