Childhood Cancer Research Results and Study Updates

The combination of dabrafenib (Tafinlar) and trametinib (Mekinist) shrank more brain tumors, kept the tumors at bay for longer, and caused fewer side effects than chemotherapy, trial results showed. The children all had glioma with a BRAF V600 mutation that could not be surgically removed or came back after surgery.

The Molecular Characterization Initiative will offer state-of-the-art diagnoses to children, adolescents, and young adults with central nervous system tumors.

An NCI clinical trial finds the drug selumetinib improves outcomes for children with neurofibromatosis type 1 (NF1), shrinking inoperable tumors called plexiform neurofibromas, reducing pain, and improving function and overall quality of life.

Children with retinoblastoma in low- and middle-income countries were, on average, diagnosed at an older age and with more advanced disease than those in high-income countries, an analysis shows. The data provide clues about global disparities in outcomes.

For children and young adults with certain relapsed B-cell acute lymphoblastic leukemia (B-ALL), the immunotherapy drug blinatumomab is superior to standard chemotherapy, an NCI-sponsored Children’s Oncology Group trial shows.

Only 1.5% of children with acute lymphoblastic leukemia who skipped radiation had a recurrence in the central nervous system, according to a recent trial. The therapy, which is intended to prevent such a recurrence, can have devastating side effects.

For many children with high-risk neuroblastoma, receiving two separate stem cell transplants is more beneficial than receiving one, according to the results of an NCI-supported clinical trial conducted by the Children’s Oncology Group.

FDA has approved entrectinib (Rozlytrek) for the treatment of children and adults with tumors bearing an NTRK gene fusion. The approval also covers adults with non-small cell lung cancer harboring a ROS1 gene fusion.

To prepare for the proposed Childhood Cancer Data Initiative, NCI sponsored a 3-day symposium that brought together pediatric cancer researchers, advocates, and other stakeholders.

An early report from the NCI–COG Pediatric MATCH trial shows that 24% of young patients with advanced cancer who had their tumors tested for genetic changes were eligible to receive one of the targeted therapies being tested.

Some children with liver cancer may need less chemotherapy than is typically used, new research suggests. The study included children and infants with hepatoblastoma whose tumors had been surgically removed when the disease was diagnosed.

NCI has created special clinics that bring together clinicians, patients, and advocates to promote more rapid progress against rare cancers. The effort includes both rare pediatric cancers and central nervous system tumors in adults.

An experimental CAR T-cell therapy may have potential as a treatment for several types of childhood cancer, results from a new study in mice suggest. The CAR T cells eradicated tumors in mouse models of several different childhood cancers, including two forms of sarcoma and medulloblastoma.

A liquid biopsy blood test can detect DNA from brain tumors called diffuse midline gliomas, researchers have found. This minimally invasive test could be used to identify and follow molecular changes in children with these highly lethal brain tumors.
