RATIONALE: Internal radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving radiation therapy through a special catheter that is placed in the breast may kill any tumor cells that remain after surgery. It may also be an effective treatment for breast cancer.

PURPOSE: This phase II trial is studying how well internal radiation therapy given through a special catheter works in treating women with early-stage breast cancer.

Arms Assigned Interventions
Experimental: Radiotherapy Radiation: accelerated partial breast irradiation

This multiple site, prospective, non-randomized dose escalation study has been designed to determine the safety and feasibility of delivering accelerated partial breast irradiation (APBI)with the Contura™ MLB balloon catheter in a short course, 2 day fashion.

Dose Level 1 - 7 Gy X 4 Dose Level 2 - 8.25 Gy X 3 Dose Level 3 - 10.25 X 2

Radiation: intracavitary balloon brachytherapy
The Contura MLB balloon catheter is used to position tissue and radioactive sources during breast brachytherapy treatments.

Detailed Description:



  • To determine local disease control in women with early-stage breast cancer treated with shorter courses of accelerated partial-breast radiotherapy (APBI) delivered with a breast brachytherapy applicator.


  • To determine whether the acceptable toxicity rates of APBI can be preserved when further accelerating the dose delivery scheme from the commonly applied ten treatments delivered twice daily over 5 days to two treatments delivered over 2 days.
  • To assess the rate of excellent or good cosmesis at 3 years after shorter courses of APBI.
  • To identify covariants associated with and predictive of poor cosmetic outcome in patients treated with an overnight course of APBI.

OUTLINE: This is a multicenter study.

Patients undergo placement of the Contura™ MLB device into the lumpectomy cavity followed by CT scan for treatment planning. Approximately 1-5 days after balloon placement, patients undergo accelerated partial-breast radiotherapy twice daily over 2 days.

After completion of study therapy, patients are followed up periodically for 5 years.
