Neuro-Oncologist · Rhode Island Hospital
Dr. Eric T. Wong
The doctor whose care the founders wanted the money to reach.
Several of the families behind this event came to know him through their own treatment. When the standard protocol stopped working, he was often the one willing to try an approach built on basic science instead. That is why the founders chose to point the fundraising at his work.
Money raised by Reason to Run is directed toward that kind of work: early, unproven research that established grants rarely cover.
His research
A major focus of Dr. Wong's research is Tumor Treating Fields, a treatment that fights glioblastoma with low-intensity electric fields rather than with drugs or radiation.
How it works
A tumor grows because its cells keep splitting in two. To split, a cell has to pull its contents apart into two new cells. Tumor Treating Fields alternate back and forth 200,000 times a second, and they interfere with the parts of the cell that do that pulling. The cell fails to divide properly and dies. There are also signs that this damage may help the immune system recognize the tumor.
How patients use it
Patients wear four adhesive pads on a shaved scalp, wired to the device that produces the fields, for at least 18 hours a day. The pads are changed every three to four days. Wearing it consistently matters: in one trial, patients who wore it at least 18 hours a day lived longer than those who wore it less.
Where it stands
The FDA approved it for glioblastoma that has come back in 2011, and for newly diagnosed glioblastoma in 2015. That made it a fourth kind of treatment, alongside surgery, radiation, and chemotherapy. In the large trial behind the 2015 approval, patients who added it to standard chemotherapy lived a median of 20.9 months, compared with 16.0 months on chemotherapy alone.
What his lab studies
The hard part is aiming it. Electric fields don't travel through the head in a simple, predictable path the way a radiation beam does. They spread differently through each kind of tissue, and fluid changes where they go most of all: the fluid around the brain, swelling around a tumor, and the fluid-filled center of some tumors can each make the field at the tumor stronger or weaker. Dr. Wong's group builds 3D computer models from each patient's own scans to show where the fields will actually be strongest. That guides where the pads are placed, so the strongest field reaches the tumor.
The therapy is now also being tested in lung, ovarian, and pancreatic cancers, and his group has modeled how the fields move through the chest and pelvis as well.
