Fine-Tuning the Tumour Microenvironment: Current Perspectives on the Mechanisms of Tumour Immunosuppression

Immunotherapy has revolutionised the treatment of cancers by harnessing the power of the immune system to eradicate malignant tissue. However, it is well recognised that some cancers are highly resistant to these therapies, which is in part attributed to the immunosuppressive landscape of the tumour microenvironment (TME). The contexture of the TME is highly heterogeneous and contains a complex architecture of immune, stromal, vascular and tumour cells in addition to acellular components such as the extracellular matrix. While understanding the dynamics of the TME has been instrumental in predicting durable responses to immunotherapy and developing new treatment strategies, recent evidence challenges the fundamental paradigms of how tumours can effectively subvert immunosurveillance. Here, we discuss the various immunosuppressive features of the TME and how fine-tuning these mechanisms, rather than ablating them completely, may result in a more comprehensive and balanced anti-tumour response.

What matters for people with brain cancer? Selecting clinical quality indicators for an Australian Brain Cancer Registry

The goal of a clinical quality registry is to deliver immediate gains in survival and quality of life by delivering timely feedback to practitioners, thereby ensuring every patient receives the best existing treatment. We are developing an Australian Brain Cancer Registry (ABCR) to identify, describe, and measure the impact of the variation and gaps in brain cancer care from the time of diagnosis to the end of life.

Childhood cancers not on the rise in SA and NT, but disparity remains for Indigenous children in the NT

Despite national and global reports of rising incidences of cancer affecting children and young people, a new analysis has found rates of childhood cancer have remained unchanged over the last 30 years in South Australia and the Northern Territory.

Precision medicine offering new hope for kids with aggressive cancers

A world-first study involving more than 100 cancer researchers and clinicians across Australia – including from The Kids Research Institute Australia and Perth Children’s Hospital – has shown that precision medicine can significantly improve outcomes for children with high-risk cancer.

Temporally restricted activation of IFNβ signaling determines response to immune checkpoint therapy

The biological determinants of the response to immune checkpoint blockade (ICB) in cancer remain incompletely understood. Little is known about dynamic biological events that underpin therapeutic efficacy due to the inability to frequently sample tumours in patients.

Case report: congenital intraventricular meningioma demonstrated with fetal MRI

Congenital intracranial meningiomas are rare lesions. We present a case of congenital intraventricular cystic meningioma, initially characterized with fetal MRI and confirmed postnatally with histopathology. To our knowledge, this is the first in vivo description of a congenital meningioma with fetal MRI. The fetal MRI was able to characterize the lesion as an atypical intraventricular mass which was separate from the choroid plexus, differentiating the mass from a choroid plexus neoplasm.

Assessment of Cannabidiol and Delta9-Tetrahydrocannabiol in Mouse Models of Medulloblastoma and Ependymoma

Children with medulloblastoma and ependymoma are treated with a multidisciplinary approach that incorporates surgery, radiotherapy, and chemotherapy; however, overall survival rates for patients with high-risk disease remain unsatisfactory. Data indicate that plant-derived cannabinoids are effective against adult glioblastoma; however, preclinical evidence supporting their use in pediatric brain cancers is lacking. Here we investigated the potential role for Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) in medulloblastoma and ependymoma. Dose-dependent cytotoxicity of medulloblastoma and ependymoma cells was induced by THC and CBD in vitro, and a synergistic reduction in viability was observed when both drugs were combined.

Exploiting the reactive oxygen species imbalance in high-risk paediatric acute lymphoblastic leukaemia through auranofin

The prognosis for high-risk childhood acute leukaemias remains dismal and established treatment protocols often cause long-term side effects in survivors. This study aims to identify more effective and safer therapeutics for these patients.
