The Effects of Radiation in Reconstructed Breasts

The Effects of Radiation Therapy on the Reconstructed Breast: An Evaluation Using MR Imaging

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

研究概览

详细说明

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.

研究人群

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.

描述

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
