Bladder surgery after Ewing sarcoma helps Paralympian get back on the slopes
Thomas Walsh’s email signature includes the phrase, “No struggle, no progress.” It’s a motto that Thomas, 27, has lived by since he was a teenager. An avid skier who has been competing since he was just 5 years old, he faced a different kind of opponent when he was diagnosed with Ewing sarcoma at age ... Read More
Genomic ‘fingerprinting’ yields better treatments for pediatric solid cancers
Genomic profiling is increasingly used for solid tumors in adults and for pediatric brain tumors and blood cancers, allowing treatments to be matched to patients’ mutations. But for children with solid tumors, genomic fingerprinting has been elusive, because these cancers are so varied and individually so rare. Therapies therefore remain non-specific: chemotherapy, surgery, and/or radiation. ... Read More
Generations of excellence in caring for childhood bone cancers: Dr. Gebhardt and Dr. Anderson
When Dr. Mark Gebhardt was a surgical resident at Boston Children’s Hospital in the early ’80s, doctors were just starting to use chemotherapy to treat bone cancers like osteosarcoma and Ewing sarcoma. Boston Children’s and the Dana-Farber Cancer Institute were among the first places to offer this treatment. They were also among the first to ... Read More
Looking for cancer’s Achilles heel: The Pediatric Cancer Dependency Map
Thanks to developments in precision medicine, some adult cancers are now treated with designer drugs that target the genetic mutations that caused them. But most children with cancer have not reaped the same benefits. Unlike adult cancers, childhood cancers carry few genetic mutations. And the mutations these tumors do have are typically harder to make ... Read More
Bone cancer surgery: A difficult choice
Nolan and Natasha might never have met if they hadn’t been diagnosed with bone cancer. Nolan, 13, is a natural athlete who lives in Maine. Natasha, 11, lives in Rhode Island and loves music and theater. As kids go, the two are pretty different — except for their osteosarcoma diagnoses and the surgery to remove ... Read More
Meet BORIS: A new culprit in drug-resistant cancer?
Like a Russian bot corrupting U.S. elections, or a new prime minister wreaking havoc in the U.K., a protein named BORIS is showing itself to be a malevolent player in some childhood cancers. New research fingers BORIS as a culprit that can hack the neuroblastoma genome, rousing the cancer cells from dormancy after certain types ... Read More
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 ... Read More
ctDNA: Bringing ‘liquid biopsies’ to pediatric solid tumors
Our blood carries tiny amounts of DNA from broken-up cells. If we have cancer, some of that DNA comes from tumor cells. Studies performed with adult cancers have shown that this circulating tumor DNA (ctDNA) may offer crucial clues about tumor genetic mutations and how tumors respond to treatment. Brian Crompton, MD, with colleagues at ... Read More
CRISPR-Cas9 screen opens new targets for Ewing sarcoma, other childhood cancers
While the genetic mutations driving adult cancers can sometimes be targeted with drugs, most pediatric cancers lack good targets. That’s because their driving genetic alterations often create fusion proteins that aren’t easy for drugs to attack. “This is one reason why it is notoriously hard to make targeted drugs against childhood cancers — their cancer-promoting ...

Cancer researchers hit a bullseye with a new drug target for Ewing sarcoma
Screening a class of recently-developed drug compounds — so-called “CDK inhibitors” capable of blocking CDK7/12/13 proteins — against hundreds of different human cancer cell lines, researchers at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center have found that CDK12 inhibitors pack a particularly lethal punch to Ewing sarcoma, a rare cancer typically affecting children and young adults. “No one ...
