Each year, more than 15,000 American children and teenagers will be diagnosed with cancer. While great progress has been made in treating many types of childhood cancer, it remains the leading cause of disease-related death among kids who make it past infancy in the United States . One reason for that sobering reality is our relatively limited knowledge about the precise biological mechanisms responsible for childhood cancers—information vital for designing targeted therapies to fight the disease in all its varied forms.
Now, two complementary studies have brought into clearer focus the genomic landscapes of many types of childhood cancer [2, 3]. The studies, which analyzed DNA data representing tumor and normal tissue from more than 2,600 young people with cancer, uncovered thousands of genomic alterations in about 200 different genes that appear to drive childhood cancers. These so-called “driver genes” included many that were different than those found in similar studies of adult cancers, as well as a considerable number of mutations that appear amenable to targeting with precision therapies already available or under development.

Tremendous progress continues to be made against the Emperor of All Maladies, cancer. One of the most exciting areas of progress involves immunotherapy, a treatment strategy that harnesses the natural ability of the body’s own immune cells to attack and kill tumor cells. A lot of extremely hard work has gone into this research, so I was thrilled to learn that the Food and Drug Administration (FDA) just announced today its first approval of a promising type of immunotherapy called CAR-T cell therapy for kids and young adults with B-cell acute lymphoblastic leukemia (ALL)—the most common childhood cancer in the U.S.
ALL is a cancer of white blood cells called lymphocytes. Its treatment with chemotherapy drugs, developed with NIH support, has transformed ALL’s prognosis in kids from often fatal to largely treatable: about 90 percent of young patients now recover. But for those for whom the treatment fails, the prognosis is grim.
In the spring of 2012, Emily Whitehead of Philipsburg, PA was one such patient. The little girl was deathly ill, and her parents were worried they’d run out of options. That’s when doctors at Children’s Hospital of Philadelphia gave Emily and her parents new hope. Carl June and his team had successfully treated three adults with their version of CAR-T cell therapy, which is grounded in initial basic research supported by NIH [1,2]. Moving forward with additional clinical tests, they treated Emily—their first pediatric patient—that April. For a while, it was touch and go, and Emily almost died. But by May 2012, her cancer was in remission. Today, five years later, 12-year-old Emily remains cancer free and is thriving. And I’ve had the great privilege of getting to know Emily and her parents over the last few years.

My blog usually celebrates biomedical advances made possible by NIH-supported research. But every August, I like to try something different and highlight an aspect of the scientific world that might not make headlines. This year, I’d like to take a moment to pay tribute to just a few of the many NIH family members around the country who, without pay or fanfare, freely give of themselves to make a difference in their communities.
I’d like to start by recognizing my wife Diane Baker, a genetic counselor who has always found time during her busy career to volunteer. When I was first being considered as NIH director, we had lots of kitchen table discussions about what it might mean for us as a couple. We decided to approach the position as a partnership. Diane immediately embraced the NIH community and, true to her giving spirit, now contributes to some wonderful charities that lend a welcome hand to patients and their loved ones who come to the NIH Clinical Center here in Bethesda, MD.
