Multicenter study
Surgical and Oncologic Outcomes of Robotic and Conventional Nipple-Sparing Mastectomy With Immediate Reconstruction
Park et al. Annals of Surgical Oncology. 2022.
Study in one sentence
The study pooled international data to compare surgical and early oncologic outcomes between robotic and conventional nipple-sparing mastectomy with immediate reconstruction.
Why was this study conducted?
Robotic nipple-sparing mastectomy had mostly been reported from a limited number of single centers.
The authors pooled international data to compare robotic and conventional nipple-sparing mastectomy in a larger group.
How was the study performed?
The analysis pooled data on 755 nipple-sparing mastectomy procedures in 659 women (609 with breast cancer and 50 undergoing risk-reducing mastectomy), all with immediate reconstruction.
Propensity-score matching was used to adjust for differences between the groups. Outcomes included 30-day complications, nipple necrosis, complication severity and early disease-free and overall survival.
What this may mean for patients
After propensity-score matching, the robotic group had a lower observed complication rate, and early oncologic outcomes did not differ significantly between the groups.
This adds larger comparative data to a field previously dominated by single-center reports.
Patients considering either approach should still discuss whether they are suitable candidates and what the trade-offs are.

Editorial note
Summary based on the published abstract. The study is observational: a lower observed complication rate in the robotic group must not be read as proof that the robot causes better outcomes. Verified citation: Park HS et al., Ann Surg Oncol 2022;29(11):6646–6657, DOI 10.1245/s10434-022-11865-x.
