Trial Description


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.

Further Study Information


  • 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.

Eligibility Criteria

  • Unifocal breast cancer
  • No multicentric carcinoma (tumors in different quadrants of the breast or tumors separated by ≥ 4 cm)
  • No palpable or radiographically suspicious contralateral axillary, ipsilateral or contralateral supraclavicular, infraclavicular, or internal mammary lymph nodes unless these are histologically confirmed negative

  • No Paget's disease of the nipple
  • No distant metastatic disease
  • Hormone-receptor status not specified


  • Female
  • Menopausal status not specified
  • Not pregnant or lactating
  • Negative pregnancy test

  • No collagen vascular disorders, specifically systemic lupus erythematosus, scleroderma, or dermatomyositis
  • No psychiatric, neurologic, or addictive disorders that would preclude obtaining informed consent
