Oncologic Outcomes of Minimal Access Nipple-sparing Mastectomy Compared With Conventional Approach in Breast Cancer

Long-term Oncologic Outcomes of Minimal Access (Endoscopic or Robotic Assisted) Nipple-sparing Mastectomy Compared With Conventional Approach in Breast Cancer - a Propensity Score Matching Analysis

In this study the investigators investigate the oncological outcomes of minimal access nipple sparing mastectomy compared with conventional nipple sparing mastectomy for the treatment of breast cancer

A retrospective analysis of a prospectively collected database was conducted from single institute to compare the oncologic outcomes of MA-NSM versus C-NSM. The clinical results and oncologic outcome (margin involved rate, local recurrence and overall survival) were compared between groups. To prevent bias, a case control approach was conducted with propensity score matching (PSM) method.

Inclusion Criteria:

• primary operable breast cancer and had undergone NSM

Exclusion Criteria:

• had metastatic disease, non-malignant breast disease cases, bilateral breast cancer cases, recurrent breast cancer as well as male breast cancer cases and patients who did not undergo NSM
