What if a medication you’ve probably never given much thought to—one that’s been sitting quietly on pharmacy shelves for decades—could actually help fight one of the deadliest brain cancers known to medicine?
That’s the exciting possibility researchers are now exploring. In a recent study, scientists discovered that gabapentin, a widely used drug for nerve pain and seizures, may extend the lives of patients battling glioblastoma, a notoriously aggressive form of brain cancer.
This isn’t a miracle cure. But it could be a major turning point.
Understanding Glioblastoma: The Clock Is Ticking
Glioblastoma isn’t your average cancer. It’s fast-growing, relentless, and alarmingly difficult to treat. Even with surgery, chemotherapy, and radiation, the average survival time for most patients hovers around 12 to 15 months. That’s it.
And here’s the kicker: despite decades of research and countless clinical trials, survival rates haven’t improved significantly in years.
That’s why any hint of progress—especially using something as accessible and safe as gabapentin—is huge.
Gabapentin: More Than Just a Pain Reliever
If you’ve ever had shingles, nerve pain, or even epilepsy, you might be familiar with gabapentin. It’s been FDA-approved for years and has a solid reputation for safety.
But what scientists from Mass General Brigham and UCSF just discovered takes its potential to a whole new level.
Their research showed that patients with glioblastoma who were also taking gabapentin lived several months longer than those who weren’t. In one hospital group, the average survival improved from 12 to 16 months. In another, it jumped from 14.7 to 20.8 months.
In the world of brain cancer, that’s not just a few months. That’s weddings attended. Birthdays celebrated. Milestones reached.
The Science Behind the Discovery: TSP-1 and Tumor Growth
So how exactly does a nerve pain drug slow down brain cancer?

It all comes down to a protein called thrombospondin-1 (TSP-1). This sneaky molecule acts like a go-between for neurons and tumor cells. In glioblastoma, TSP-1 helps tumors grow by encouraging nerve cells to interact with cancer cells—a process scientists now believe fuels aggressive tumor expansion.
Gabapentin, it turns out, blocks this interaction. By disrupting the way TSP-1 supports cancer growth, gabapentin could be throwing a serious wrench into the tumor’s game plan.
Think of it like this: glioblastoma is a wildfire, and TSP-1 is the oxygen feeding it. Gabapentin doesn’t douse the fire, but it chokes the oxygen just enough to slow things down.
Real-World Results: Over 1,000 Patients Studied
This wasn’t a one-off lab experiment. The research team analyzed data from over 1,000 glioblastoma patients treated at two major hospitals. Across the board, the findings were consistent: those on gabapentin lived longer.
Now, it’s important to be clear—this wasn’t a randomized, controlled trial. That means we can’t say for certain that gabapentin was the only reason for the improved survival. But the trend is hard to ignore.
And since gabapentin is already FDA-approved and widely prescribed, it opens the door to fast-tracked clinical trials—a rarity in the slow, complex world of cancer research.
Why This Discovery Matters Right Now
There are several reasons why this study is so promising:
- Speed of implementation – Gabapentin is already approved and available. Doctors don’t have to wait years for new drug approvals.
- Low toxicity – Unlike chemotherapy, gabapentin doesn’t wreck the body in the process of doing its job.
- Widespread use – Patients around the world are already taking gabapentin for other conditions. This research might give them an unexpected added benefit.
Even better? The drug is relatively affordable, making it more accessible than many new targeted cancer therapies that cost thousands per dose.
What Comes Next: Trials and Treatment Strategies
Of course, more work needs to be done. Researchers are now calling for controlled clinical trials to see if gabapentin’s benefits hold up under stricter testing conditions. These studies will help doctors figure out:
- The ideal dosage for glioblastoma patients
- Which patients benefit the most
- Whether combining gabapentin with other treatments offers even better outcomes
If these trials are successful, gabapentin could become a standard add-on to glioblastoma care—something that helps give patients a little more time, and a lot more hope.

Conclusion: A Familiar Drug With Unexpected Power
In the relentless search for better cancer treatments, the spotlight often falls on the newest, most high-tech drugs. But sometimes, hope comes from the unlikeliest places—a pill we already trust, quietly doing more than we ever imagined.
Gabapentin isn’t a cure for glioblastoma. But it’s a sign that we don’t always need to reinvent the wheel. Sometimes, we just need to see an old tool in a new light.
For thousands of patients and families facing a brain cancer diagnosis, even a few more months can mean the world. And this small, everyday medication might just help make that possible.
