What this trial studies

This study compares the outcomes of pre-pectoral versus subpectoral breast reconstruction techniques following single-port insufflation endoscopic nipple-sparing mastectomy in women with early-stage invasive breast cancer. It is an ambispective cohort study that includes both retrospective and prospective patient data, focusing on breast satisfaction as the primary outcome. The study aims to enroll 80 patients, with a 1:1 ratio in each reconstruction group, and will analyze data collected from medical records and direct patient recruitment over a span of several years.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18 to 70 with early-stage invasive breast cancer who require total mastectomy and are willing to undergo breast reconstruction.

Not a fit: Patients with serious medical conditions or those who do not meet the eligibility criteria for breast reconstruction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance patient satisfaction with breast reconstruction outcomes after mastectomy.

How similar studies have performed: Previous studies have explored various breast reconstruction techniques, but this specific comparison of pre-pectoral and subpectoral methods using endoscopic techniques is relatively novel.
