Acellular Dermal Matrix in Tissue Expander Breast Reconstruction: A Prospective, Randomized, Clinical Trial Comparing SurgiMend PRS and AlloDerm RTU
In recent years, acellular dermal matrix (ADM) products have increasingly been utilized in
breast reconstruction in order to protect the implant from exposure under a thin mastectomy
skin flap while also allowing better control of the inframammary fold and, therefore, a
better cosmetic result. In current clinical practice, cost is a factor in considering
procedures and adjunct products. AlloDerm RTU and SurgiMend PRS are dissimilar in cost, with
AlloDerm RTU more costly by 30-50%, and it is unclear if they are similar in efficacy.
This study will be a prospective, randomized-to-test article (ADM), controlled,
blinded-to-aesthetic/biopsy specimen evaluator trial. It will provide a way to assess the
relative performance and complication rates between the AlloDerm RTU and SurgiMend PRS
product as well as the relative economics of these two treatment options. Study subjects
will only be randomized to one of two surgical mesh products. Patient information including
age, BMI, smoking history, tumor size and location, preoperative bra cup size, mastectomy
specimen weight, mastectomy method, plastic surgeon, mastectomy surgeon, quality of skin,
tissue expander type and maximal volume, intra-operative fill volume, gel/saline implant
type and size, chemotherapy, and radiation therapy will be summarized.
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment
To determine the overall complication rate for tissue expander breast reconstruction patients using SurgiMend PRS and AlloDerm RTU ADM products.
After first procedure: 10-14 days, then 2, 4, 6, and 10 weeks after drain removal; After second procedure: 1-2 weeks, 6 weeks, 1 year, and 3 years
