Leptomeningeal dissemination: a sinister pattern of medulloblastoma growth.

J Neurosurg Pediatr 2019 Feb 15:1-9. Epub 2019 Feb 15.

3Cancer Research Program, Research Institute of the McGill University Health Center and Department of Surgery, McGill University, Montreal, Quebec, Canada.

Leptomeningeal dissemination (LMD) is the defining pattern of metastasis for medulloblastoma. Although LMD is responsible for virtually 100% of medulloblastoma deaths, it remains the least well-understood part of medulloblastoma pathogenesis. The fact that medulloblastomas rarely metastasize outside the CNS but rather spread almost exclusively to the spinal and intracranial leptomeninges has fostered the long-held belief that medulloblastoma cells spread directly through the CSF, not the bloodstream.

Department of Radiology, Box 218, University of Cambridge, Cambridge CB2 0QQ, United Kingdom; Cambridge University Hospitals NHS Foundation Trust, Addenbrooke's Hospital, Cambridge, United Kingdom, CB2 0QQ. Electronic address:

The tumor microenvironment is characteristically acidic and this extracellular acidosis is known to play a role in carcinogenesis and metastasis and can affect tumor chemosensitivity and radiosensitivity. Intracellular pH has been used as a possible biomarker of salvageable tissue in ischemic stroke. A non-invasive MRI-based approach for the determination and imaging of cerebral pH would be a powerful tool in cancer diagnosis and monitoring, as well as stroke treatment planning. Read More

The role of ACKR3 in breast, lung and brain cancer.

Mol Pharmacol 2019 Feb 11. Epub 2019 Feb 11.

Universidad Autonoma Madrid;

Recent reports regarding the significance of chemokine receptors in disease have put a spotlight on ACKR3. This atypical chemokine receptor is overexpressed in numerous cancer types and has been involved in the modulation of tumour cell proliferation and migration, tumour angiogenesis or resistance to drugs, thus contributing to cancer progression and metastasis occurrence. Here we focus on the clinical significance and potential mechanisms underlying the pathological role of ACKR3 in breast, lung and brain cancer and discuss its possible relevance as prognostic factor and potential therapeutic target in these contexts.

Cellular MRI Reveals Altered Brain Arrest of Genetically Engineered Metastatic Breast Cancer Cells.

Contrast Media Mol Imaging 2019 8;2019:6501231. Epub 2019 Jan 8.

Robarts Research Institute, The University of Western Ontario, London, Ontario, Canada.

Purpose: The combined use of anatomical magnetic resonance imaging (MRI), cellular MRI, and bioluminescence imaging (BLI) allows for sensitive and improved monitoring of brain metastasis in preclinical cancer models. By using these complementary technologies, we can acquire measurements of viable single cell arrest in the brain after systemic administration, the clearance and/or retention of these cells thereafter, the growth into overt tumours, and quantification of tumour volume and relative cancer cell viability over time. While BLI is very useful in measuring cell viability, some considerations have been reported using cells engineered with luciferase such as increased tumour volume variation, changes in pattern of metastatic disease, and inhibition of tumour growth.

Molecular Mechanisms of Action of Tocotrienols in Cancer: Recent Trends and Advancements.

Int J Mol Sci 2019 Feb 2;20(3). Epub 2019 Feb 2.

Department of Pharmacology, Faculty of Pharmacy, Kayseri 38039, Turkey.

Tocotrienols, found in several natural sources such as rice bran, annatto seeds, and palm oil have been reported to exert various beneficial health promoting properties especially against chronic diseases, including cancer. The incidence of cancer is rapidly increasing around the world not only because of continual aging and growth in global population, but also due to the adaptation of Western lifestyle behaviours, including intake of high fat diets and low physical activity. Tocotrienols can suppress the growth of different malignancies, including those of breast, lung, ovary, prostate, liver, brain, colon, myeloma, and pancreas. Read More

AMPA receptor antagonist perampanel affects glioblastoma cell growth and glutamate release in vitro.

PLoS One 2019 4;14(2):e0211644. Epub 2019 Feb 4.

Oscar-Langendorff-Institute of Physiology, Rostock University Medical Center, Rostock, Germany.

Epileptic seizures are frequent in patients with glioblastoma, and anticonvulsive treatment is often necessary. While clinical guidelines recommend all approved anticonvulsants, so far it is still unclear which of the available drugs is the best therapeutic option for treating glioma-associated seizures, also in view of possible anti-tumorigenic effects. In our study, we employed four patient-derived low-passage cell lines of glioblastoma and three cell lines of brain metastases, and challenged these cultures with four anticonvulsants with different mechanisms of action: levetiracetam, valproic acid, carbamazepine and perampanel.

Paracellular and transcellular migration of metastatic cells through the cerebral endothelium.

J Cell Mol Med 2019 Feb 2. Epub 2019 Feb 2.

Institute of Life Sciences, Vasile Goldiş Western University of Arad, Arad, Romania.

Breast cancer and melanoma are among the most frequent cancer types leading to brain metastases. Despite the unquestionable clinical significance, important aspects of the development of secondary tumours of the central nervous system are largely uncharacterized, including extravasation of metastatic cells through the blood-brain barrier. By using transmission electron microscopy, here we followed interactions of cancer cells and brain endothelial cells during the adhesion, intercalation/incorporation and transendothelial migration steps.

Brain and bone cancer targeting by a ferrofluid composed of superparamagnetic iron-oxide/silica/carbon nanoparticles (earthicles).

Acta Biomater 2019 Feb 1. Epub 2019 Feb 1.

Advanced Materials and Nanobiotechnology Laboratory, Center for Targeted Drug Delivery, Department of Biomedical and Pharmaceutical Sciences, Chapman University, Irvine, CA 92618-1908, USA; Advanced Materials and Nanobiotechnology Laboratory, Department of Bioengineering, University of Illinois, Chicago, IL 60607-7052, USA. Electronic address:

Despite the advances in molecularly targeted therapies, delivery across the blood-brain barrier (BBB) and the targeting of brain tumors remains a challenge. Like brain, bone is a common site of metastasis and requires therapies capable of discerning the tumor from its healthy cellular milieu. To tackle these challenges, we made a variation on the previously proposed concept of the earthicle and fabricated an aqueous, surfactant-free ferrofluid containing superparamagnetic iron oxide nanoparticles (SPIONs) coated with silicate mesolayers and carbon shells, having 13 nm in size on average.

Leukemia-derived exosomes and cytokines pave the way for entry into the brain.

J Leukoc Biol 2019 Jan 31. Epub 2019 Jan 31.

Department of Pathology, University of New Mexico, Albuquerque, New Mexico, USA.

Infiltration of acute lymphoblastic leukemia (ALL) blasts into the CNS remains as a major clinical problem, with high risk for chemotherapy-resistant relapse and treatment-related morbidity. Despite the common inclusion of CNS prophylaxis treatments in therapy regimens, there are significant gaps in understanding the mechanisms that mediate leukemia cell entry into the CNS as well as roles for resident cells in the brain. In this study, we employ a xenograft model of human B cell precursor (BCP)-ALL in immunocompromised mice. Read More

Abscess Formation in Metastatic Brain Tumor with History of Immune Checkpoint Inhibitor: A Case Report.

NMC Case Rep J 2019 Jan 18;6(1):11-15. Epub 2018 Dec 18.

Department of Neurosurgery, Institute of Biomedical and Health Sciences, Hiroshima University, Hiroshima, Hiroshima, Japan.

We present the case of a 68-year-old man with brain metastasis from lung cancer and a history of immune checkpoint inhibitor administration, with overlapping abscess within the metastatic lesion. He initially received antibiotic treatment under a diagnosis of brain abscess because of a hyper-intense area on diffusion-weighted imaging inside the gadolinium-enhanced wall. The size of the enhanced lesion did not change much, but the extent of perifocal edema decreased after antibiotic treatment. Read More

The genomic imprint of cancer therapies helps timing the formation of metastases.

Int J Cancer 2019 Jan 29. Epub 2019 Jan 29.

Institute of Enzymology, Research Centre for Natural Sciences, Hungarian Academy of Sciences, Budapest, Hungary.

A retrospective determination of the time of metastasis formation is essential for a better understanding of the evolution of oligometastatic cancer. This study was based on the hypothesis that genomic alterations induced by cancer therapies could be used to determine the temporal order of the treatment and the formation of metastases. We analysed the whole genome sequence of a primary tumour sample and three metastatic sites derived from autopsy samples from a young never-smoker lung adenocarcinoma patient with an activating EGFR mutation.
