Standard therapy for patients with early stage breast cancer consists of surgery to remove the cancer followed by radiation therapy. One question regarding radiation therapy for early stage breast cancer is whether the entire breast needs to be radiated or only a more limited area surrounding the tumor. Whole-breast irradiation (WBI) is radiation therapy given to the whole breast. Partial-breast irradiation (PBI) is radiation therapy given only to the area of the breast where the cancer was removed (called the "tumor bed").

The investigators hope the option of PBI will reduce side effects from radiation therapy and shorten the radiation treatment process when compared to WBI, since only part of the breast is being treated. The investigators also hope that this will make such treatment more convenient for breast cancer patients.

The purpose of the study is to evaluate the the safety of external-beam PBI in selected early breast cancer patients utilizing PBI in ten daily fractions over two weeks. The investigators will also evaluate the local control and the cosmetic results.

Primary Outcome Measures:
  • Safety of external-beam PBI utilizing 40Gy in ten daily fractions over two weeks [ Time Frame: 2 years ]

    To evaluate the safety of external-beam PBI in selected stages 0 and I female breast cancer patients utilizing 40 Gy in ten daily fractions over two weeks. The study will be deemed too toxic if >10% of enrolled patients have at least one of the following outcomes within 24 months of completion of PBI.

    1. Grade 3 or 4 skin/subcutaneous or pulmonary toxicity.
    2. The development of clinical fat necrosis.
    3. The development of rib fracture on the ipsilateral treated side, detected either clinically and/or radiographically.

Secondary Outcome Measures:
  • Evaluate local control rates [ Time Frame: 2 years ]
    To evaluate local control rates (analyzed separately for patients with DCIS and invasive cancer)

  • Evaluate distant control rates [ Time Frame: 2 years ]
    To evaluate distant control rates

  • Evaluate breast cosmesis [ Time Frame: 2 years ]
    Breast Cosmesis will be assessed pretreatment, at the end of treatment, 4-9 weeks following completion of treatment, every 6 months for the first 5 years, then annually for 5 years. The Cosmetic Scoring System (Appendix 2) will be used.

Estimated Enrollment: 100
Study Start Date: May 2012
Estimated Study Completion Date: August 2024
Primary Completion Date: August 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Partial Breast Irradiation
Partial Breast Irradiation using 40 Gy in 10 fractions over 2 weeks
Radiation: External Beam Partial-Breast Irradiation
40 Gy in ten daily fractions over two weeks

Detailed Description:

After signing the consent form, the following will be assessed.

-CT scan of the breast that had the cancer removed to help plan the radiation therapy. This is referred to as a CT-simulation. This scan is done routinely as part of the regular treatment.

PBI Study Treatment: You will be given PBI once daily over 10 treatment days (Mon-Fri) over a 2 week period. During this time you will have a weekly interview, physical examination, and your skin will be assessed for any side effects of the radiation.

PBI will begin between 4 weeks to 3 months after breast surgery or 2-6 weeks after chemotherapy (if you have been given chemotherapy).

After the final dose of the study:

You will have the following scheduled follow-up visits: one at the completion of the radiation, once or twice during weeks 3-9 after the completion of radiation, once every 6 months for five years, and then once every year for the following five years after the completion of radiation therapy.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Unicentric Stage I invasive ductal breast cancer or Grade I or II DCIS measuring less than or equal to 2cm on pathology and/or mammography
  • Histologically negative tumor margin 2 mm or more from any inked edges, or no tumor in a re-excision specimen or final shaved specimen
