Exploring targeted treatments for children with low-grade brain tumors
Children diagnosed with low-grade astrocytomas, the most common type of pediatric brain tumor, have close to 90 percent overall survival rates. However, the growth of the tumors, as well as the standard treatments (neurosurgery and chemotherapy) required to control them, can cause serious side effects, including damaging developing brains and bodies. Researchers at Dana-Farber/Boston Children’s Cancer and Blood ... Read More about Exploring targeted treatments for children with low-grade brain tumors
Chemical screening suggests a two-pronged treatment for pediatric Ewing sarcoma
For children with Ewing sarcoma, an aggressive bone cancer, a combination of two different classes of drugs may work synergistically to turn off the drivers fueling this disease, finds a new study. The combination appears to be more powerful than relying on either treatment alone. The study, published online last month in Clinical Cancer Research, is the latest in a ...

PET imaging shows if PD-1 cancer immunotherapy is working
PD-1 is a protein on our T cells that normally keeps these immune cells from running amok. A growing number of cancer drugs are designed to inhibit PD-1, enabling patients’ T-cells to attack and kill cancerous cells. PD-1 blockers such as pembrolizumab (Keytruda) have been helpful in treating several cancers including melanoma, non-small cell lung ...

Single-cell sequencing reveals glioblastoma’s shape-shifting nature
Glioblastoma, a cancer that arises in the brain’s supporting glial cells, is one of the worst diagnoses a child can receive. The grade IV, highly malignant tumor aggressively infiltrates healthy brain tissue, and most children die of the disease within one to two years of diagnosis, similar to adults. “The current approach is surgical removal, ...

Stella’s story: Winning against neuroblastoma
The Downey family was enjoying the holidays with family in Guatemala in 2017 when their 13-month-old daughter Stella started having unusual symptoms. “She was very clingy towards me and not acting like herself,” says Stella’s mom, Fiorella, a child life specialist at Boston Children’s Hospital. “It was so extreme that I brought her to the ...

Limb-salvage surgery is best option for Andrew
It was quite a spring for Andrew Hedberg. The rising high school sophomore made the varsity golf team and was elected class president for the upcoming school year. Most importantly, the bone cancer that once threatened his left leg and his life remained in remission. All of this validated the decision that Andrew’s family made seven years ...

What role do genetics play in pediatric leukemia?
Leukemia is the most common childhood cancer, accounting for 31 percent of cancers in children younger than 15, and 25 percent of those younger than 20. Most young patients develop leukemia because of a mutation, or DNA change, that occurs randomly in a blood cell only, and is not inherited from a parent. On the other ...

Children wait for new cancer drugs 6.5 years longer than adults
A 20-year analysis finds that FDA-approved cancer drugs took a median of 6.5 years to go from the first clinical trial in adults to the first trial in children. That’s not good enough for researchers at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, who are calling for expanding children’s access to experimental cancer therapies. “It’s ...

‘Nanobodies’ from alpacas could help bring CAR T-cell therapy to solid tumors
In 1989, two undergraduate students at the Free University of Brussels were asked to test frozen blood serum from camels, and stumbled on a previously unknown kind of antibody. It was a miniaturized version of a human antibody, made up only of two heavy protein chains, rather than two light and two heavy chains. As ...
