  Purpose

RATIONALE: Radiation therapy uses high-energy x-rays and other types of radiation to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells.

PURPOSE: This clinical trial is studying how well partial breast radiation therapy works in treating women undergoing breast-conserving therapy for early stage breast cancer.

Primary Outcome Measures:
  • Cosmetic outcome as determined by an established scale employed by the radiation oncologist and the surgeon [ Time Frame: 1 month after RT & Q3mos for one year ] [ Designated as safety issue: No ]
  • Patient satisfaction with partial breast irradiation as measured by a questionnaire [ Time Frame: Pre-treatment 1 mo 3 mo 6 mo 9 mo 1yr 5 yr ] [ Designated as safety issue: No ]
  • Wound healing and overall complication rate after partial breast irradiation [ Time Frame: 1 month after RT & Q3mos for one year ] [ Designated as safety issue: No ]
  • Determination of which patients are best suited for each individual technique of partial breast irradiation [ Time Frame: Patients will be followed for a period of five years following completion of radiation. ] [ Designated as safety issue: No ]
  • Ipsilateral breast tumor recurrence rates and tumor bed recurrence rates [ Time Frame: Ipsilateral breast 6 mos after dx, bilateral annually x 5 years ] [ Designated as safety issue: No ]

Enrollment: 29
Study Start Date: June 2007
Estimated Study Completion Date: October 2014
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MammoSite Brachytherapy
Patients undergo partial breast irradiation comprising either MammoSite® brachytherapy twice daily for 5-10 days
Procedure: adjuvant therapy
If chemotherapy is planned, it must begin no earlier than two weeks following completion of radiation. If chemotherapy is given first, a minimum of 2 weeks from the last cycle must elapse prior to the start of radiation.
Radiation: brachytherapy
Patients undergo partial breast irradiation comprising either MammoSite® brachytherapy twice daily for 5-10 days
Experimental: 3-dimensional conformal radiotherapy
3-dimensional conformal radiotherapy twice daily for 5-10 days.
Procedure: adjuvant therapy
If chemotherapy is planned, it must begin no earlier than two weeks following completion of radiation. If chemotherapy is given first, a minimum of 2 weeks from the last cycle must elapse prior to the start of radiation.
Radiation: 3-dimensional conformal radiation therapy
3-dimensional conformal radiotherapy twice daily for 5-10 days.

Detailed Description:

OBJECTIVES:

  • To determine the cosmetic outcome resulting from partial breast irradiation using two different techniques.
  • To determine patient satisfaction with partial breast irradiation as it pertains to their overall treatment experience as measured by a questionnaire.
  • To determine if there are patient factors that limit a patient's suitability to receive partial breast irradiation delivered by a particular technique.
  • To evaluate wound healing and overall complication rate after partial breast irradiation.
  • To determine ipsilateral breast tumor recurrence rates and tumor bed recurrence rates.

OUTLINE: Patients undergo partial breast irradiation comprising either MammoSite® brachytherapy twice daily for 5-10 days OR 3-dimensional conformal radiotherapy twice daily for 5-10 days.

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