Summary
Brief summary (as posted)
This is a national multicenter, prospective, cohort study. The study aims to compare surgical safety (e.g., surgical complication rates), surgery-related indicators (e.g., operation time, number of operations, surgery-related costs, contralateral breast adjustment operation rates), aesthetic outcomes (e.g., BREAST-Q scores, Harris scores, SCAR-Q scores, Ueda scores and QLQ-BR45 scores), and divorce rate between patients undergoing delayed endoscopic direct-to-implant breast reconstruction via an axillary approach and those undergoing the two-stage expander-to-implant breast reconstruction following simple mastectomy.

Inclusion Criteria: * Female patients aged 18-70 years (inclusive) who have undergone simple mastectomy for breast cancer; * At least 1 year after simple mastectomy or 6 months after completion of radiotherapy, with good local skin viability and skin laxity; * Voluntary provision of informed consent. Exclusion Criteria: * Local/regional recurrence or uncontrolled distant metastasis detected upon re-examination (clinical, imaging, or pathological evidence); * Pectoralis major muscle was resected during the initial surgery; * Preoperative severe comorbidities with poor general condition, rendering the patient unable to tolerate surgery; * Immunodeficiency; * Long-term smoking history or poorly controlled diabetes mellitus; * Currently participating in other clinical trials that may affect the results of this study.
