Bioprosthetic Mesh to Expand the Lower Pole in Tissue Expander Reconstruction

5 april 2019 uppdaterad av: M.D. Anderson Cancer Center

Bioprosthetic Mesh to Expand the Lower Pole in Tissue Expander Reconstruction: A Blinded, Prospective, Randomized, Controlled Trial

The goal of this clinical research study is to learn if the complication rate and post-surgical appearance differ based on what type of mesh is used for breast reconstruction surgery.

Detaljerad beskrivning

If you agree to take part in this study, you will be randomly assigned (as in the roll of a dice) to receive Surgimend mesh or Alloderm mesh.

Breast Reconstruction Surgery:

All techniques of the breast reconstruction surgery are considered to be standard of care. You will be given a separate consent form to sign that explains the procedure and risks in more detail.

Data Collection:

Information about you will be collected, including your age, height, weight, breast size, past medical and smoking history, tumor size and location, and the surgical method used for the breast reconstruction surgery.

Information about the breast reconstruction surgery, such as what type of expanders are used, the surgical methods, and your recovery from the surgery will also be collected.

Follow-Up Visits:

About 1 week after the breast reconstruction surgery is complete, you will come in for a follow-up visit and the surgical team will check the surgery incision site and tissue used for the breast reconstruction surgery for any possible complications.

About 2 weeks after the breast reconstruction surgery, the expansion process will begin, as long as you do not have any complications that would prevent beginning the expansion process. During the expansion process, the surgeon will adjust the tissue expanders to stretch the area under the skin and muscle to make room for a breast implant(s).

After you begin the expansion process, you will return to the clinic 1 time each week for additional expansion until the desired size is reached. During each of the expansion process visits, you will be checked for any side effects, including fluid build up and infection.

After the expansion process is complete, you will return to the clinic 3 months later to receive your implant(s). About 1 to 12 months after you receive the implant(s), you will return to the clinic and 5 photographs will be taken to evaluate the appearance of the new implant(s). The photographs will be taken of the front, right and left sides of the implant(s) site and will be taken against a blue background. Your private areas will be covered (as much as possible). Your confidentiality will be protected at all times. You will not be identifiable personally from the discussion or presentation of the data. Unique study numbers will be assigned to the photographs.

Length of Study:

Your participation on this study will be over after you have received your permanent breast implant(s) and the photographs have been taken.

This is an investigational study.

Up to 398 patients will take part in this study. All will be enrolled at the MD Anderson main campus or one of the MD Anderson regional care centers.

Beskrivning

Inclusion Criteria:

  1. Patients undergoing immediate tissue expander reconstruction following mastectomy by any of the surgeon co-investigators are eligible for the study.
  2. Patients 18 years of age or older are eligible for the study.
  3. Patients undergoing skin-sparing mastectomy utilizing bioprosthetic mesh are eligible for the study.
  4. Patients who have not undergone autologous tissue breast reconstruction and intend to undergo implant only breast reconstruction.
