RATIONALE: Internal radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. It may also cause less damage to normal tissue.

PURPOSE: This phase II trial is studying how well partial-breast radiation therapy works in treating women with early-stage breast cancer.

Condition Intervention Phase
Breast Cancer Procedure: adjuvant therapy Radiation: accelerated partial breast irradiation Radiation: intracavitary balloon brachytherapy Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Single Institution, Prospective, Non-randomized Study of Partial Breast Irradiation Using the MammoSite Radiation Therapy System (Breast Brachytherapy Applicator)

Further study details as provided by Ohio State University Comprehensive Cancer Center:

Primary Outcome Measures:
  • Proportion of local recurrence [ Time Frame: up to 5 years ]
    • Local recurrence is defined as either invasive or non-invasive local recurrence within the target volume.
    • Ipsilateral elsewhere recurrence is defined as either invasive or non-invasive local recurrence outside of the target volume.

Secondary Outcome Measures:
  • Safety and toxicity [ Time Frame: up to 30 months after radiotherapy ]
  • Cosmetic results [ Time Frame: up to 30 months ]

Enrollment: 0
Detailed Description:



  • To examine the efficacy of MammoSite® Radiation Therapy System (RTS) in delivering partial-breast irradiation to women with early-stage breast cancer.


  • To assess the toxicities associated with MammoSite® RTS in these patients.
  • To evaluate the cosmetic results in the breast after brachytherapy with the MammoSite® RTS.
  • To correlate the cosmetic results with the use of chemotherapy, volume of the implant, and distance from the implant to the skin.
  • To correlate the local recurrence rate with time between surgery and implant.

OUTLINE: Patients undergo placement of the MammoSite® Radiation Therapy System (RTS) device into the cavity where the tumor was removed either at the time of surgery or percutaneously under ultrasound guidance after surgery. Within 2-5 days after the device implant, patients undergo partial-breast irradiation delivered by MammoSite® RTS twice daily for 5 days.

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


Ages Eligible for Study:   45 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No


  • Histologically confirmed ductal carcinoma in situ (DCIS) of the breast or invasive breast adenocarcinoma

    • Stage 0, I, or II (T2, N0; tumor size ≤ 3 cm) disease
    • Pathologic staging of the axilla preferred

      • Clinical staging of the axilla allowed for patients ≥ 70 years of age with hormone receptor-positive tumors
  • Unicentric tumor

    • Microscopic multifocality allowed as long as the total tumor size is ≤ 3 cm
  • Must have undergone lumpectomy as definitive surgery

    • Negative surgical margins, defined as no tumor at the inked margin of resection after final surgery

      • Re-excision to obtain negative margins allowed
  • Must have adequate skin spacing between balloon surface and surface of the skin and lung (≥ 7 mm)
  • No multicentric carcinoma (invasive or DCIS) in more than one quadrant
  • No clinically or pathologically positive regional lymph nodes
  • No extensive intraductal component, defined as DCIS extending beyond the primary invasive component into normal breast parenchyma and composing > 25% of the primary tumor
  • Hormone receptor status not specified


  • Menopausal status not specified
  • Not pregnant or nursing
  • Negative pregnancy test
  • Fertile patients must use effective contraception
  • No collagen-vascular disease, including any of the following:

    • Dermatomyositis
    • Systemic lupus erythematosus
    • Scleroderma-mixed connective tissue disease
