Tracking Post-Implant Seed Migration in Permanent Breast Seed Implant

Permanent breast seed implant (PBSI) is an accelerated partial breast irradiation modality for the treatment of early-stage breast cancer. Stranded 103Pd seeds are permanently implanted in and around the post-lumpectomy seroma according to a pre-treatment CT-based plan. Questions have arisen regarding the potential post-implant migration of seeds given the mobility of breast tissue. Further, seed displacements and coalescence have been observed in the weeks following implant by centres performing the technique.
