Purpose: Breast conservation surgery (BCS) has become a standard treatment method for patients with early breast cancer. Endoscopy-assisted BCS (EABCS) can be performed through an inconspicuous periareolar and a small axillary incision for sentinel node biopsy, which may give better cosmetic outcomes than conventional BCS skin incisions. This study was designed to evaluate the feasibility of EABCS for patients with early breast cancer. Methods: Forty-three patients were candidates for EABCS, and EABCS was performed in 40 patients with breast cancer between January 2008 and July 2010. Their clinicopathological features were retrospectively analyzed. Operative time, margin status, complications, and relapse-free survival were compared with those of patients treated by conventional BCS and who were treated at the same institute during the same period. Results: The most common lesion site of the EABCS and conventional BCS groups was the upper area of the breast. Tumor size in all patients was less than 4 cm (range, 0.4-3.7 cm), and nodal involvement was found in eight (20%) patients in the BCS group. The mean operative time was 110 minutes for the EABCS group and 107 minutes for the conventional BCS group, and those were not significantly different. No significant difference in frozen or final margin status was observed between the EABCS and conventional BCS groups. Relapse-frlee survival was statistically equivalent between the groups with a median follow-up of 12 months. Postoperative complications occurred in five cases in four patients with EABCS, which was not significantly different from conventional BCS. Conclusion: Performing EABCS in patients with early breast cancer seems to be feasible and safe. Further study with a longer-term follow-up may be needed to confirm the clinical value of EABCS.
