Brief Summary:
The primary objective of this study is to use LR imaging to evaluate the effects of adjuvant radiation therapy on reconstructed breasts.

Condition or disease Intervention/treatment
Breast Cancer Procedure: contract-enhanced MRI Radiation: Unilateral Adjuvant Radiation Therapy

Detailed Description:
Immediate breast reconstruction following mastectomy has become an increasingly popular and accepted treatment option among breast cancer patients. This change in practice has resulted in a significant number of patients who undergo radiation therapy after breast reconstruction. Following irradiation, the reconstructed breast often experiences fibrotic contracture, volume loss, altered pigmentation, or some combination thereof, producing an asymmetric and aesthetically compromised result. The effects of radiation on reconstructed breasts as well as the implications that such changes have for timing of reconstructive surgery, post-operative management and surveillance imaging are topics of growing importance in plastic surgery, radiology and surgical oncology.

Groups and Cohorts

Intervention Details:
  • Procedure: contract-enhanced MRI
    Patients will have contrast-enhanced MRI of the breasts.
  • Radiation: Unilateral Adjuvant Radiation Therapy
    The study group will consist breasts receiving post-operative radiation, and the control group will consist of the patient's breasts on the non-radiated side. In this way, patients will act as their own control.

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Reconstructed Breast Volume [ Time Frame: up to 1 year after radiation ]
    This will be compared at 2 points: before radiation and 1 year after radiation is completed between the 2 breasts.

  2. Vascular Fibrosis [ Time Frame: up to 1 year after radiation ]
    This will be compared at 2 points: before radiation and 1 year after radiation is completed between the 2 breasts.

  3. Dermal Thickness [ Time Frame: up to 1 year after radiation ]
    This will be compared at 2 pionts: before radiation and 1 year after radiation is completed between the 2 breasts


Secondary Outcome Measures :
  1. Presence of Fat Necrosis in the Breast [ Time Frame: up to 1 year after radiation ]
    This will be assessed at 2 points: before radiation and 1 year after radiation is completed between the 2 breasts.

  2. Evidence of Cancer Recurrence [ Time Frame: up to 1 year after radiation ]
    This will assessed at 2 points: before radiation and 1 year after radiation is completed between the 2 breasts.

  3. Symmetry [ Time Frame: up to 1 year after radiation ]
    This will be assessed at 2 points; before radiation and 1 year after radiation is completed between the 2 breasts.

  4. Hyperpigmentation [ Time Frame: up to 1 year after radiation ]
    This will be assessed at 2 points: before radiation and 1 year after radiation is completed between the 2 breasts.

  5. Contracture [ Time Frame: up to 1 year after radiation ]
    This will be assessed at 2 points:before radiation and 1 year after radiation is completed between the 2 breasts.

  6. Aesthetic Result [ Time Frame: up to 1 year after radiation ]
    This will be assessed at 2 points: before radiation and 1 year after radiation is completed between the 2 breasts.

Ages Eligible for Study:   18 Years to 90 Years   (Adult, Older Adult)
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
The target population will consist of patients with a diagnosis of unilateral breast cancer who elect to undero bilateral mastectomy with immediate free flap reconstruction. Patients will be treated by members of the Division of Plastic and Reconstructive Surgery and will receive postoperative radiation therapy to the affected breast.
Criteria

Inclusion Criteria:

  • Female patients between 18 and 90 years of age.
  • Patients with a diagnosis of unilateral breast cancer who elect to undergo bilateral mastectomy with immediate free flap reconstruction.
  • Patients must also have a locally advanced tumor that requires adjuvant radiation therapy following reconstruction.

Exclusion Criteria:

  • Women who do not undergo immediate, bilateral breast reconstruction using a free flap.
  • Women who do not require unilateral, adjuvant radiation therapy
  • Women who are pregnant
  • Women who have altered renal function, defined as a personal history of diabetic, hypertensive or autoimmune nephropathy and/or on routine preoperative testing are found to have a serum creatinine greater than or equal to 1.3
