Single Port Endoscopic Breast Conserving Surgery

Prospective Clinical Study of Single Port Endoscopic Breast Conserving Surgery or Open Breast Conserving Surgery for Early Breast Cancer

The center plans to carry out a prospective clinical study of single hole total endoscopic breast conserving surgery for early breast cancer compared with open breast conserving surgery, to provide high-level evidence-based medical evidence for the development of endoscopic breast conserving surgery for early breast cancer.

Data show that breast cancer has surpassed lung cancer asthemost prevalent malignant tumor in the world, and traditional open surgery is highly invasive and has poor cosmetic results. This study investigates the results of endoscopic breast- conserving surgery(E-BCS) versus conventional breast-conserving surgery(C-BCS) in the treatment of patients with early-stage breast cancer and to compare the advantages and disadvantages of the two surgical procedures, so as to provide the best evidence for the rational choice of the procedure by both doctors and patients.

Inclusion Criteria:

1. Breast cancer confirmed by pathology；
2. Tumor <5 cm, TNM stage 0-II；
3. Single Port Endoscopic or traditional open surgery; (4)20 to 70 years old female patients.

Exclusion Criteria:

1. Bilateral breast cancer;
2. Reconstruction after breast conserving surgery ;
3. Basic information is not complete；
4. Breast conserving surgery was converted to modified radical resection or subcutaneous adenoidectomy.
