ClinConnect Summary

This will be a prospective, open label, single arm, controlled study, assessing the safety and efficacy of diffusing alpha emitters radiation therapy (DaRT) delivered through radioactive sources \[Ra-224 containing stainless-steel 316LVM tubes- (Alpha DaRT seeds)\] inserted into malignant breast lesions.

This approach combines the advantages of local intratumoral irradiation of the tumor, as used in conventional brachytherapy, with the power of the alpha radiation emitting atoms, that will be introduced in quantities considerably lower than radiation therapy already used in patients.
