Partial Breast Irradiation Using Interstitial Permanent Palladium-103 Seed Implant

Official Title

Partial Breast Irradiation Using Interstitial Permanent Palladium-103 Seed Implant

Summary:

Permanent Breast Seed Implant (PBSI) has been demonstrated to be a well accepted and well tolerated form of partial breast radiation therapy. This protocol aims to build on the initial experience and to further refine the technique and collect toxicity and cost data, especially in comparison to alternate forms of breast radiation therapy.

Trial Description

Primary Outcome:

  • Implant quality
Secondary Outcome:
  • Eligibility for implant based on seroma size and location within breast
  • Feasibility of 3D US for procedure guidance
  • Cosmesis
  • Toxicity
  • Quality of life
  • Dose to Organs at risk
  • Cost
25 women with low stage (pT1pN0) breast cancer, grade 1 or 2, will be accrued for adjuvant partial breast radiation therapy using PBSI and prospectively followed for 5 years. The primary aims is to evaluate implant quality according to recognized dosimetric parameters. Secondary aims include elaboration of approaches to different technical scenarios imposed by variation in seroma size, shape and location within the breast (expanding the technical manual to include recommended approaches to implants in different sectors of the breast and in different size breasts), incorporation of the use of live 3D ultrasound in the procedure (as opposed to current use of 2D US), assessment of patient acceptance and quality of life, physician assessment of cosmesis, assessment of toxicity, and recording of cost to the patient and health care system compared to alternate forms of breast radiation therapy.
