Combining CAR-T cells and inhibitor drugs for high-risk neuroblastoma
Chimeric antigen receptor (CAR)-T cell therapy is a potent emerging weapon against cancer, altering patients’ T cells so they can better find and destroy tumor cells. But CAR-T cell therapy doesn’t work well in every cancer — including many cases of neuroblastoma, a cancer that begins in young children’s nerve tissue and can metastasize to ...

Could a GI bug’s toxin curb hard-to-treat breast cancer?
Clostridium difficile can cause devastating inflammatory gastrointestinal infections, with much of the damage inflicted by a toxin the bug produces. But research from Boston Children’s Hospital suggests that the same toxin could also be a useful tool for curbing highly aggressive triple-negative breast cancers that don’t respond to chemotherapy. Min Dong, PhD, in the Department ... Read More about Could a GI bug’s toxin curb hard-to-treat breast cancer?
Making immunotherapy safe for AML
Acute myeloid leukemia (AML), the second most common leukemia in children, is hard to treat and has a five-year survival rate of just 65 to 70 percent, according to the American Cancer Society. While immunotherapies like monoclonal antibodies or CAR T-cell therapy are effective for certain blood cancers, they have not been possible in AML ...

All eyes on retinoblastoma: How Lyla and her mom are helping change lives
Meghan Landry firmly believes that art saved her daughter Lyla’s life. Now, she hopes to leverage the power of creativity to help support other kids like Lyla, who was diagnosed with retinoblastoma at 18 months old. Meghan, who lived in Florida at the time, was waiting with Lyla for a routine pediatrician appointment when she ...

‘Life is so much better now’: Ethan finds treatment for mixed germ cell brain tumor
Ethan Winchenbach was playing with his dogs when he first noticed that something was off. “My vision changed, but only when I looked down,” he remembers. “It was really disorienting.” His mother, Becky, who is a nurse, knew immediately that something wasn’t right. When the symptoms didn’t improve, she made him an appointment with his ... Read More about ‘Life is so much better now’: Ethan finds treatment for mixed germ cell brain tumor
Tackling an aggressive, treatment-resistant lymphoma where it lives
Anaplastic large cell lymphoma, a form of non-Hodgkin lymphoma, is the most common aggressive lymphoma in children. Chemotherapy and radiation fail to cure about 30 percent of cases. When tumors are driven by the oncogene ALK — which is the case for the majority of children — kinase inhibitor drugs like crizotinib are very effective ...

One-time treatment could block a deadly form of graft-versus-host disease
Even when a bone marrow transplant cures leukemia or lymphoma, patients can still pass away from graft-versus-host disease (GVHD), in which T cells in the donor graft attack the recipient’s own tissues. Leslie Kean, MD, PhD, director of stem cell transplant at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, has long sought to prevent this ...

No backing down: Sophia takes on a rare form of liver cancer
Sophia LaBorde is headstrong and “doesn’t back down,” says her mother, Alicia. So last year when Sophia had some gastrointestinal discomfort and a low appetite, she asked her parents to bring her to her local pediatrician. And when test after test ruled out more common culprits — lactose intolerance, heartburn, even thyroid disease — she ... Read More about No backing down: Sophia takes on a rare form of liver cancer
A new cancer mechanism: Failed cellular housekeeping
Cancer can stem from mutations in many different genes. New research from Boston Children’s Hospital and Dana-Farber Cancer Institute pinpoints a gene that, when mutated, causes cancer through a mechanism not before seen: Inability of cells to dispose of their trash, namely defective strands of RNA. This mechanism appears to cut across many different malignancies, ... Read More about A new cancer mechanism: Failed cellular housekeeping
An unexpected journey reveals a potent way to attack tumors
Research on the effects of prenatal exposure to the Zika virus has yielded an unexpected dividend: a potentially promising way to trigger natural killer (NK) cells to fight cancer. NK cells are first-responder immune cells. When enough of their activating receptors are triggered, they mobilize to kill infected, stressed, or cancerous cells at an early ...
