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.

Health problems that develop years later as a result of a cancer treatment are known as late effects. The Childhood Cancer Survivor Study (CCSS) was started in 1994 to better understand and address these late effects.

The drug sodium thiosulfate can protect the hearing of children with cancer undergoing treatment with the chemotherapy drug cisplatin, results from a new clinical trial show. The trial involved children with a form of liver cancer called hepatoblastoma.

This NCI-funded Children’s Oncology Group trial tested the addition of nelarabine (Arranon) to standard treatment for children and young adults with T-cell acute lymphoblastic leukemia (T-ALL).

In a phase 2 clinical trial, the investigational drug selumetinib shrank tumors in some children with the genetic syndrome neurofibromatosis type 1 (NF1). The tumors, called neurofibromas, can cause pain, difficulty breathing or walking, and disfigurement.

Results from an NCI-sponsored clinical trial may point to an important change in how some children with advanced Wilms tumor, a form of kidney cancer, are treated.

An interactive website designed to promote physical activity among children and adolescents who have completed treatment for cancer may indeed help encourage them to get regular exercise, according to preliminary results from a pilot study.

An NCI-funded study has found significant differences in the genetics of acute myeloid leukemia in younger and older patients. The findings could help guide the development of treatments tailored specifically for childhood AML.

On November 9, the FDA approved dasatinib (Sprycel®) for the treatment of children with chronic myelogenous leukemia (CML) whose cancer cells express the Philadelphia chromosome and whose disease is in a relatively early stage, known as the chronic phase.

Progress continues to be made with the Gabriella Miller Kids First Research Program, which is creating opportunities for investigators from different research communities to share resources and collaborate on research into childhood cancers and certain birth defects.

FDA has approved tisagenlecleucel (Kymriah™), a type of immunotherapy called CAR T-cell therapy, for some children and young adults with advanced acute lymphoblastic leukemia (ALL).

In a small clinical trial, the drug crizotinib shrank tumors in children with cancers that have alterations in the ALK gene.

Two studies have identified proteins that drive growth of diffuse intrinsic pontine glioma (DIPG) tumor cells. Blocking these targets with investigational drugs slowed tumor growth in animal models.

Researchers have created a long-sought-after mouse model for an aggressive form of acute lymphoblastic leukemia that occurs commonly in infants and that the researchers believe can accelerate the development of new therapies for the disease.

In an early-phase clinical trial of a new oral drug, selumetinib, children with the common genetic disorder neurofibromatosis type 1 (NF1) and plexiform neurofibromas, tumors of the peripheral nerves, tolerated selumetinib and, in most cases, responded to it with tumor shrinkage.
