Interactions between acute lymphoblastic leukemia and bone marrow stromal cells influence response to therapy

The cure rate for pediatric patients with B precursor acute lymphoblastic leukemia (pre-B ALL) is steadily improving, however relapses do occur despite...

A New Model to Investigate the Action of Radiation and Cigarette Smoke on Head and Neck Cancer Cells

Smokers are at an increased risk of developing mucosal head and neck squamous cell cancers (HNSCCs) and have a worse prognosis when treated. The cellular and molecular mechanisms underlying the latter has not been established. We therefore developed an in vitro model to investigate the effects of radiation and smoking on mucosal HNSCCs.

Boosting the influenza vaccine schedule in children with cancer: a prospective open-label study

Current immunization guidelines recommend one dose of influenza vaccine for children aged ≥9 years and two doses for younger or vaccine-naïve children. However, children receiving chemotherapy have an attenuated immune response. We performed a prospective open-label study in children undergoing treatment for cancer at Perth Children's Hospital, Western Australia, to examine the safety and efficacy of a boosted influenza schedule.

Germ-line and somatic DICER1 mutations in pineoblastoma

This study suggests that germ-line DICER1 mutations make a clinically significant contribution to PinB, establishing DICER1 as an important susceptibility...

Accuracy of Central Neuro-Imaging Review of DIPG Compared with Histopathology in the International DIPG Registry

Diffuse intrinsic pontine glioma (DIPG) remains a clinico-radiologic diagnosis without routine tissue acquisition. Reliable imaging distinction between DIPG and other pontine tumors with potentially more favorable prognoses and treatment considerations is essential.

Defining the molecular features of radiation-induced glioma: A systematic review and meta-analysis

Cranial radiation therapy is essential in treating many pediatric cancers, especially brain tumors; however, its use comes with the risk of developing second malignancies. Cranial radiation-induced gliomas (RIGs) are aggressive high-grade tumors with a dismal prognosis, for which no standard therapy exists. A definitive molecular signature for RIGs has not yet been established. We sought to address this gap by performing a systematic review and meta-analysis of the molecular features of cranial RIGs.

Ultra high-risk PFA ependymoma is characterized by loss of chromosome 6q

Within PF-EPN-A, 1q gain is a marker of poor prognosis, however, it is unclear if within PF-EPN-A additional cytogenetic events exist which can refine risk stratification.

Pediatric pineoblastoma: A pooled outcome study of North American and Australian therapeutic data

Pineoblastoma is a rare brain tumor usually diagnosed in children. Given its rarity, no pineoblastoma-specific trials have been conducted. Studies have included pineoblastoma accruing for other embryonal tumors over the past 30 years.

Conventional Therapies Deplete Brain-Infiltrating Adaptive Immune Cells in a Mouse Model of Group 3 Medulloblastoma Implicating Myeloid Cells as Favorable Immunotherapy Targets

Medulloblastoma is the most common childhood brain cancer. Mainstay treatments of radiation and chemotherapy have not changed in decades and new treatment approaches are crucial for the improvement of clinical outcomes. To date, immunotherapies for medulloblastoma have been unsuccessful, and studies investigating the immune microenvironment of the disease and the impact of current therapies are limited.
