RESUMEN
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. RESULTS: All patients were alive 1 year following surgery with no locoregional recurrence or distant metastases and without any critical complications. The average length of incision was less in patients receiving E-SM+E-SLNB (4.4 vs. 19.4 cm; P < 0.001), but time in surgery was longer (131.6 vs. 99.2 min; P = 0.024). After 1 year, nearly all E-SM+E-SLNB patients rated satisfaction with their appearance as excellent or good (23/24; 95.8% vs. 19/25; 76.0%; P < 0.001), and exhibited less disturbance of sensory (P < 0.001) and motor function (P = 0.014) relative to modified radical resection. CONCLUSIONS: E-SM+E-SLNB provides significant aesthetic and functional advantages for patients with early stage breast cancer without compromising medical efficacy as assessed at 16 months postsurgery.
