Oncological outcome of single-port insufflation endoscopic nipple-sparing mastectomy versus open mastectomy in early breast cancer patients: a study protocol for a randomised controlled trial.

Introduction: Breast cancer is the most prevalent cancer and the leading cause of cancer-related death in women. Conventional open mastectomy (C-OM) is one of the most common procedures for breast cancer, which involves the removal of the nipple-areola complex and a large proportion of the breast skin, leading to poor cosmetic effect and restriction of upper extremity function. Single-port insufflation endoscopic nipple-sparing mastectomy (SIE-NSM) could conceal the incision along the wrinkles in the axilla, preserve all the breast skin and nipple-areola complex and provide a better cosmetic outcome and quality of life.

Preliminary results for treatment of early stage breast cancer with endoscopic subcutaneous mastectomy combined with endoscopic sentinel lymph node biopsy in China.

Background And Objectives: To evaluate efficacy and aesthetic outcome for combined endoscopic subcutaneous mastectomy (E-SM) and endoscopic sentinel lymph node biopsy (E-SLNB) in early stage breast cancer patients.

Methods: Combined E-SM+E-SLNB was compared to modified radical resection in a cohort of Chinese patients (n = 49) with stages I and II breast cancer. Patient satisfaction with the aesthetic results was assessed 1 year after surgery with a 5-item-by-4-step scoring system for evaluating cosmetic outcomes.
