Theranostic, has positioned itself as a
promising technique to fight cancer,
especially when using radioactive isotopes,
where it has demonstrated good efficiency in human
cancer treatment and in the animal phase study. The
technique basically consists in using a chemical
element with several radioactive isotopes. One
diagnostic (gamma or β+ emitter) and another isotope
of the same therapeutic element (alpha, β+, β- or
Auger electrons). These isotopes must be linked to a
vector molecule expressed by the tumor cells of the
corresponding type of cancer. Radioisotopes can also
be encapsulated in nanoparticles.
