Brain Cancer Survivor Creates Test to Predict Best Treatment

When Andrew Satterlee was diagnosed with brain cancer at 20, his doctors faced a terrible dilemma: they couldn't agree on which drugs would work best for his unique tumor. He and his family had to make a life-or-death decision without knowing if they were choosing the right treatment.

That uncertainty shaped the next 18 years of his life. Today, Andrew is an assistant professor and director of the Brain SLiCE program at UNC's Eshelman Innovation, working to ensure no patient faces the same frightening guesswork he did.

The technology Andrew helped develop sounds like science fiction. Doctors take a living tumor sample and place it onto tissue outside the body, then expose it to different treatments to see what actually works. Within just four days, they can tell whether a tumor will respond to a specific drug or keep growing.

"My cancer shaped my whole life. It shaped my whole career direction," Andrew explains. Doctors removed a mass the size of a ping pong ball from his brain, but the hardest part came after surgery when his medical team disagreed about treatment.

More than 700,000 Americans live with brain tumors today. Every single tumor is different, making treatment one of medicine's biggest challenges. What works for one patient might fail completely for another.

The Ripple Effect

The Brain SLiCE platform could transform cancer care far beyond brain tumors. Because the tumor samples respond on living tissue differently than they do in plastic lab dishes, doctors get a realistic preview of how treatments will work in actual patients.

The technology is personalized to each specific patient and their unique tumor. Instead of trying one drug, waiting months to see if it works, then trying another if it fails, doctors could know the best option within days.

Researchers say the platform still needs to clear regulatory hurdles before guiding everyday patient care. But brain cancer is just the beginning of what this approach could accomplish.

The same testing method could eventually help doctors choose treatments for lung cancer, abdominal tumors, and other cancers where personalizing therapy makes the difference between life and death. What started as one young man's frightening experience could help thousands of future patients skip the guesswork and get the right treatment from day one.
