Comparison of Endoscopic and Open Breast-Conserving Surgery in Breast Cancer
ClinicalTrials.gov Studies
Summary
NIH registered a randomized controlled trial (NCT07539545) comparing minimal accessory-incision-assisted endoscopic breast-conserving surgery (M-E-BCS) with conventional open breast-conserving surgery (C-O-BCS) in breast cancer patients. The multicenter, open-label trial evaluates operative time, economic effects, surgical complications, postoperative aesthetics (BREAST-Q, Harris, SCAR-Q, and Ueda scores), and oncological safety outcomes including margin status and local recurrence-free survival.

What changed
The study registration adds a new randomized controlled trial to ClinicalTrials.gov. The trial enrolls breast cancer patients and randomly assigns them to either endoscopic or conventional open breast-conserving surgery, with assessments spanning operative efficiency, costs, safety, cosmetic outcomes, and long-term oncological results.
Healthcare providers and clinical investigators conducting breast cancer research should be aware of this trial as it may influence future surgical practice guidelines and comparative effectiveness evidence for breast-conserving approaches.

The Comparison Between M-E-BCS and C-O-BCS.
N/A NCT07539545 Kind: NA Apr 20, 2026
Abstract
This study is a multicenter, open-label, randomized controlled trial. The study aims to evaluate differences in operative efficiency (e.g., operative time), economic effect, surgical safety (e.g., surgical complication rates), postoperative aesthetics (e.g., BREAST-Q scores, Harris scores, SCAR-Q scores and Ueda scores), and oncological safety (e.g., margin status, no local recurrence survival) between patients undergoing M-E-BCS and patients undergoing C-O-BCS.
Conditions: Breast Cancer
Interventions: Minimal accessory-incision-assisted endoscopic breast-conserving surgery, Conventional open breast-conserving surgery
