Lucas, a Beacon of Hope: Teenager Beats Rare Brain Cancer

Lucas was six years old when he got the heartbreaking news that he had a rare kind of brain tumor. His future seemed dark, and the prognosis seemed dire. But after seven years, Lucas—who is now 13—remains a ray of optimism. The once-debilitating tumor has vanished. Lucas, a boy from Belgium, is the first child in the world to successfully battle brainstem glioma, a severe type of brain cancer.

Lucas’s tenacity astounds Dr. Jacques Grill, head of the Gustave Roussy Cancer Center’s brain tumor program in Paris. “Lucas defied all odds,” he remembers. I observed as the tumor vanished entirely across several MRI scans. The official name for this tumor is diffuse intrinsic pontine glioma (DIPG), and it affects about 300 children annually in the United States and up to 100 in France.

The medical world is commemorating the progress made in treating childhood cancer on International Childhood Cancer Day. Nowadays, more than 85% of kids with this kind of brain cancer survive for more than five years after their diagnosis. Prospects are still dismal for patients with DIPG, though; the majority pass away within a year. Only 10% of patients make it past two years, despite efforts to slow the tumor’s fast growth with radiation therapy.

A Novel Experience for Lucas and His Relatives

Lucas’s family enrolled him in the BIOMEDE study in France, setting off on an uncharted trip. This trial investigates new DIPG therapies. Lucas was given the medication everolimus at random, and he responded remarkably well to it. Over several MRI scans, his tumor completely disappeared, shocking the doctors.


Lucas stopped taking the drug a year and a half ago, but the tumor is still gone, which is a first for his medical history. Dr. Grill credits the distinct genetic composition of the tumor for Lucas’s remarkable recuperation. He thinks the drug’s susceptibility was heightened by a unique mutation.

Researchers are looking into Lucas’s situation because it intrigues them. They grow tumor organoids in lab conditions and examine genetic abnormalities. The director of the research, Marie-Anne Debily, is upbeat. She sees a potential breakthrough in which the cellular differences found in Lucas could lead to successful treatments. “Finding a medication that affects tumor cells in the same way as these cellular alterations will be the next step,” she stated.

Although the advancements show promise, prudence is advised. Dr. Grill highlights how long it takes to develop a medication from discovery. Viable treatments are still years away, he cautions. David Ziegler, a pediatric oncologist, concurs, pointing out that the field of DIPG treatment is expanding but also stressing the importance of ongoing study and clinical trials. “It’s a lengthy and drawn-out process; it takes on average 10-15 years from the first lead to become a drug,” says Dr. Grill.

Lucas’s story serves as an example of both the medical community’s commitment and the tenacity of young patients. With additional study and trials, there is optimism in the medical community that viable treatments for DIPG will be discovered. Lucas’s victory over brain cancer is motivation for kids with related illnesses and their families who are hoping for a treatment.
