What this trial studies

This feasibility study involves 60 women undergoing immediate breast reconstruction after mastectomy for breast cancer. Participants will be randomly assigned to receive either biological or synthetic mesh to support breast implants, with follow-up for 6 months to assess comfort with the allocation process. The study aims to evaluate patient satisfaction, quality of life, complications, and costs over a longer period in future research. The goal is to better understand the long-term safety and acceptability of both types of meshes.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older who are undergoing mastectomy and immediate one-stage mesh-assisted implant breast reconstruction.

Not a fit: Patients seeking revision or delayed reconstruction surgery will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve patient satisfaction and outcomes in breast reconstruction surgeries.

How similar studies have performed: Previous studies have suggested that both biological and synthetic meshes may be equally safe in the short term, but this study aims to provide more comprehensive long-term data.
