Pre- vs Sub-Pectoral Breast Reconstruction for Breast Reconstruction
(OPBC-02PREPEC Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial examines whether placing breast implants over the chest muscle (pre-pectoral) improves long-term physical comfort and quality of life compared to placing them under the muscle (sub-pectoral) after breast cancer surgery. It targets women undergoing mastectomy (removal of breast tissue) either for treatment or prevention of breast cancer. Ideal participants can complete quality of life surveys and are having skin-sparing or nipple-sparing mastectomies.
As an unphased trial, this study allows participants to contribute to innovative research that could enhance post-mastectomy outcomes.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications.
What prior data suggests that these breast reconstruction techniques are safe?
Research shows that both pre-pectoral and sub-pectoral implant-based breast reconstruction (IBBR) are safe options for patients after a mastectomy. Studies have found that pre-pectoral IBBR offers similar outcomes to sub-pectoral IBBR, with one key advantage: it results in fewer cases of capsular contracture, where scar tissue forms around the implant, causing hardness.
Other research confirms that both methods yield reliable results with comparable complication rates, including the risk of implant loss. For instance, the chance of losing a tissue expander or implant is about 10% for both methods.
These findings suggest that patients can confidently choose either option, knowing both are well-tolerated and thoroughly studied for safety.12345Why are researchers excited about this trial?
Researchers are excited about pre-pectoral and sub-pectoral implant-based breast reconstruction (IBBR) techniques because they offer unique approaches to breast reconstruction following mastectomy. Unlike traditional methods that typically place the implant under the chest muscle (sub-pectoral), pre-pectoral IBBR involves placing the implant above the muscle, potentially reducing pain and recovery time. Both methods aim to improve aesthetic outcomes and patient comfort, but the pre-pectoral approach might offer a less invasive option with faster recovery. By exploring these different placements, researchers hope to refine reconstruction techniques to enhance patient satisfaction and overall quality of life after surgery.
What evidence suggests that this trial's treatments could be effective for improving quality of life in breast reconstruction?
This trial will compare pre-pectoral and sub-pectoral implant-based breast reconstruction (IBBR) methods. Research has shown that both approaches are effective after a mastectomy. Studies have found that pre-pectoral IBBR often results in fewer cases of capsular contracture, where scar tissue tightens around the implant, with a 46% lower risk compared to sub-pectoral placement. Patients generally report satisfaction with the look and feel of pre-pectoral IBBR, and major issues like animation deformity, where the implant visibly moves with muscle movement, are absent. Both methods have similar complication rates. However, the pre-pectoral approach is gaining popularity due to its safety and effectiveness.13678

Are You a Good Fit for This Trial?
This trial is for patients who are having a skin-sparing or nipple-sparing mastectomy and opting for Implant-Based Breast Reconstruction (IBBR) as treatment or prevention of breast cancer. Participants must be able to fill out Quality of Life questionnaires and give informed consent. Those without a clinical need for IBBR or with inadequate skin flaps for pre-pectoral IBBR cannot join.Inclusion Criteria

Trial Overview
The study compares two types of breast reconstruction after mastectomy: one where the implant is placed under the chest muscle (sub-pectoral), and another where it's placed over the muscle but under the skin (pre-pectoral). The goal is to see which method offers better physical well-being in terms of chest comfort after 24 months.
