Robot-assisted versus endoscopic breast-conserving surgery for breast cancer
A Retrospective Analysis of Robot-Assisted Versus Endoscopic Breast-Conserving Surgery for Breast Cancer
This test compares robot-assisted and endoscopic breast-conserving surgery in women with a single breast tumor who want to keep their breast, to see which approach gives better surgical and cosmetic results.

What this trial studies
This is a single-center retrospective comparison of patients who underwent robot-assisted breast-conserving surgery (RABCS) or endoscopic breast-conserving surgery (E-BCS) at the Sixth Affiliated Hospital of Sun Yat-sen University. The analysis examines operative metrics, margin status, complications, and cosmetic outcomes in women with unifocal breast cancer and a tumor-to-breast volume ratio ≤20%. The protocol highlights robotic system advantages such as enhanced dexterity, a magnified three-dimensional high-definition view, and high-resolution imaging that may improve precision in the confined operative space of the breast. Being a retrospective, single-center analysis, results will reflect local surgical expertise and patient selection and will help define areas for future prospective study.
Who should consider this trial
Good fit: Women aged 18–80 with pathologically confirmed unifocal breast cancer, tumor-to-breast volume ratio ≤20%, desire for breast conservation, no distant metastasis, and eligibility for standard postoperative radiotherapy are ideal candidates.
Not a fit: Patients with diffuse lesions or microcalcifications unlikely to achieve clear margins, bilateral or inflammatory breast cancer, prior chest irradiation, pregnancy- or lactation-associated cancer, or inability to tolerate general anesthesia are unlikely to benefit from these techniques.
Why it matters
Potential benefit: If successful, the comparison could show that robot-assisted surgery provides improved precision and cosmetic outcomes with similar or lower complication rates, supporting broader adoption for selected patients.
How similar studies have performed: Small case series and single-center reports have shown the feasibility and favorable cosmetic results of robotic breast surgery, but high-quality comparative and long-term outcome data remain limited.
Eligibility criteria

Inclusion Criteria: * Female patients aged 18 to 80 years * Pathologically confirmed breast cancer prior to surgery * Sufficient glandular volume with a tumor-to-breast volume ratio ≤20% * A unifocal lesion confined to the glandular tissue * Clear desire for breast conservation and willingness to undergo R-BCS or E-BCS * No evidence of distant metastasis, no involvement of the skin or chest wall * Eligibility for standard postoperative radiotherapy Exclusion Criteria: * The presence of diffuse suspicious lesions or microcalcifications for which wide local resection was unlikely to achieve adequate negative margins or satisfactory aesthetic outcomes * Bilateral breast cancer or inflammatory breast cancer * After neoadjuvant therapy, requirement for additional concurrent surgical procedures * Inability to tolerate general anesthesia or undergo surgery * Contraindications to radiotherapy or a history of prior chest wall irradiation, pregnancy- or lactation-associated breast cancer * Refuse to undergo R-BCS or E-BCS
