effective radioimmunotherapy of metastatic her2+ bc (Mice--see bold area)

[Rich66]

Is this using her2 antibody target a radioactive particle? or is it sensitizing her2 tumors to external radiation?

[Lani]

it is a particle emitter tied to herceptin just for targetting to her2 receptors on the breast cancer

there is no external beam radiation involved

there is already in use an FDA approved particle emitter tied to rituxumab for lymphoma I believe.

It is a nuclear medicine product
