A Nigerian born
scientist, Samuel Achilefu, has won the prestigious St. Louis Award for 2014
for creating cancer-visualizing glasses.
Dr. Achilefu, a
professor of radiology and biomedical engineering, and his team developed the
imaging technology in cancer diagnosis into a wearable night vision-like
goggles so surgeons could see the cancer cells while operating.
“They basically have to
operate in the dark,” Bloomberg Businessweek quoted Dr. Achilefu, 52, as
saying.
“I thought, what if we
create something that let’s you see things that aren’t available to the
ordinary human eye.”
Dr. Achilefu won a
scholarship from the French government to study at the University of Nancy,
according to St. Louis Post-Dispatch, a regional newspaper in St. Louis, U.S.,
and is the 87th person to receive the annual award since it was established in
1931.
Married with two young
children, Dr. Achilefu moved to St. Louis after he was hired by Mallinckrodt to
start a new research department.
“Our efforts start with
two words: ‘What if?'” Dr. Achilefu said during his acceptance speech.
“These words may sound
simple, but they embody the belief that each person has the potential to make a
difference, if only he or she can take the time to understand the problem.”
According to Bloomberg,
the researchers’ technology requires two steps: First, surgeons inject a tiny
quantity of an infrared fluorescent marker into the patient’s bloodstream. The
peptides contained in the marker enables it to locate cancer cells and buries
itself inside.
After the tracer flows
through a patient’s body and clears from non-cancerous tissue – which lasts
about four hours – the operation would begin. Wearing the goggle, the doctor
can inspect tumours under an infra red light that reacts with the dye, causing
cancer cells to glow from within.
This month, the goggles
have been used on humans for the first time by surgeons at the Washington
University School of Medicine.
Four patients suffering
from breast cancer and over two dozen patients with melanoma or liver cancer
have been operated on using the goggles since they were developed.
“The goggles function
fantastically,” says Ryan Fields, a surgical oncologist who is collaborating
with Dr. Achilefu to improve on the technology.
“They allow us to see
the cells in real time, which is critical. Because the marker has not yet been
FDA-approved, doctors are currently using a different, somewhat inferior marker
that also reacts with infrared light.”
Julie Margenthaler, a
breast cancer surgeon, says tens of thousands of women who had had breast
cancer lumpectomies go back for second operations every year because of the
inability to see the microscopic extent of the tumours.
“Imagine what it would
mean if these glasses eliminated the need for follow-up surgery and the
associated pain, inconvenience and anxiety.”
Dr. Achilefu and his
team began work in 2012 after they received $2.8 million grant from the National
Institutes of Health, according to the St. Louis Post-Dispatch.
Before then, they had
been working on a lean budget provided by the Department of Defence’s Breast
Cancer Research Program.
After it was developed,
the team spent years testing the technology on mice, rats, and rabbits to
confirm the efficacy of the goggles.
“Nobody would believe
us until we showed that the goggles work,” Dr. Achilefu says.
The Food and Drug
Administration are still reviewing the goggles and a related dye Dr. Achilefu
and his co-researchers developed, according to Washington University in St.
Louis, a St. Louis based journal.
Dr. Achilefu says he
intends to keep Washington University as the primary centre for clinical trials
to evaluate the technology in patients.
“Making a difference in
society should be the goal of everybody,” Dr. Achilefu
