Brief Summary:
Evaluation and comparison of clinical and aesthetic outcomes associated with the use of two allograft dermal matrices (ADMs) currently in use for tissue assisted immediate post-mastectomy breast reconstruction.

Condition or disease Intervention/treatment Phase
Breast Reconstruction Biological: FlexHD ADM (Cohort A) Biological: AlloDerm RTU ADM (Cohort B) Not Applicable

Detailed Description:
This is a level one, prospective, randomized, controlled multi-center clinical study comparing two types of acellular dermal matrices (ADMs) currently used in immediate post-mastectomy prosthetic breast reconstruction. Comparison of these two ADMs will be made in the areas of reconstructive clinical outcomes and aesthetic outcomes. Patients will be randomized into one of two ADM groups as part of their immediate post-mastectomy breast reconstruction. Patients in both groups will be followed for twelve months after their reconstructive surgery. Clinical outcomes will be documented at 1 month, 3 months, 6 months and 12 months following breast reconstructive surgery. For one-stage breast reconstruction, aesthetic outcomes will be assessed and documented at 6 and 12 months following implant placement. For two-stage reconstruction, patients will be evaluated for aesthetic outcomes at a time point 6-12 months following expander-to-implant exchange if it does not coincide with the 12 month post-mastectomy visit.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 224 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: Prospective, randomized, controlled
Masking: Single (Outcomes Assessor)
Masking Description: 3-4 independent breast surgeons using predefined criteria will assess the aesthetic outcomes of each subject using photographs of their pre-mastectomy and 12 month post-reconstructions. The surgeons will not be apprised of the ADM type or post-mastectomy site/surgeon

Primary Outcome Measures :
  1. Post Reconstruction Complication Rates [ Time Frame: 12 months ]
    To compare the overall complication rate between the cohorts defined as either 1) post-operative infection specific to the reconstructed breast(s) requiring either intravenous antibiotic treatment or operative intervention, 2) seroma, and/or 3) reconstructive failure

Secondary Outcome Measures :
  1. Comparison of Each Complication Rate [ Time Frame: 12 months ]
    To compare each complication rate between the cohorts defined as 1) post-operative infection specific to the reconstructed breast(s) requiring either intravenous antibiotic treatment or operative intervention 20 seroma 3) reconstructive failure and 4) reoperation for reasons other than infection

  2. Comparison of Aesthetic Outcomes (Photographs) [ Time Frame: 12 months ]
    A blinded comparison of aesthetic outcomes (photographs) using pre-defined criteria
