Shortly after the discovery of the neutron in 1932, some scientists recognized the potential of boron neutron capture therapy (BNCT) as a cancer treatment. But, despite decades of research, the task of finding a delivery agent that would be more efficiently directed at the tumor without harming the surrounding tissue.
BNCT traditionally involves the introduction into tumors with non-radioactive boron-10 isotope trapping agent. Then the tumor is irradiated with a bundle of epithermal neutrons that interact with the trapping agent to produce a biologically destructive nuclear reaction. This leads to the formation of boron 11 with the release of radiation in the form of alpha particles (helium-4) and lithium ions, which kill tumor formations. Despite numerous clinical studies that demonstrated the safety of BNCT, the task was to find more selective delivery agents.
Taking advantage of the fact that cancer cells absorb more materials than normal cells, MU. Curators of Professor M. Frederick Hawthorne and his team used cancer cells to develop new delivery agents with them. When it captures a boron neutron, chemical emissions of lithium and helium occur, which penetrate the cancer cells and destroy them from the inside without harming the neighboring healthy cells.
Hawthorne and his team tested this new form of radiation therapy in mice, which led to a successful remission of cancer.
“A wide range of cancers can be disattached with our BNCT technique,” says Hawthorne. “The technique worked perfectly on mice. We are ready to move on by exploring it on larger animals, and then on humans. However, before we can start treating people, we must build the right equipment for this. When it is built, MU will introduce the first radiation therapy of its kind in the world. ”
This technology greatly promotes medicine. if it really works effectively in humans, then the cancer will not sound like a death sentence, even in the middle stages.
