Tools for the determination of the microdistribution of 10B in the framework of Boron Neutron Capture Therapy (BNCT)

CNEA researchers gave a seminar on a therapy investigation using boron.


Agustina Portu and Mario Gadan, Phds in science and technology (UNSAM), gave a talk for the members of the Center for Research in Bionanosciences (CIBION) on April 21st.

The speakers gave a brief introduction to the basics of Boron Neutron Capture Therapy (BNCT) to understand the importance of determining 10B distributions and further discussed the development of the techniques performed in their group.

This is a project that is being implemented at the National Atomic Energy Commission (CNEA), where both researchers work. The objective of his proposal is to generate the technology, facilities, and scientific and medical studies to bring a boron-based treatment to the clinical field.

In this sense, Gadan and Portu, BNCT is a form of hadrontherapy for the treatment of certain solid tumors that is based on the radiobiological effects induced by the light ions generated in the neutron capture reaction, 10B(n,α)7Li. These products deliver all their energy over very short distances, on the order of cell diameter, with the capacity to cause lethal damage. In this way, if the 10B atoms accumulate preferentially in the tumor, BNCT makes it possible to offer a selective treatment at the cellular level, this being its main radiobiological characteristic.

Thus, they commented that it is then evident that the distribution of 10B in tissues, both healthy and in the tumor, is a highly relevant factor in this therapy. In view of this, his working group has been dedicated to the development of nuclear imaging techniques, such as neutron autoradiography, and their implementation for the determination of 10B concentrations in biological samples and their spatial distribution.
