Robotic Liver Resection for Breast Cancer Metastasis: A Multicenter Case Series and Literature Review

Background: Breast cancer is a widespread disease and, when metastatic, has a bleak prognosis. The surgical approach for BCLM has had a limited role, but robotic surgery could find an important place. Methods: Data were collected from a multicenter retrospective database that includes 1070 consecutive robotic liver resections performed in nine European hospital centers from 2011 to 2023. Of the entire series, 35 were performed for BCLM in five European hospital centers. Results: The post-operative complication rate was 11.44%, but no severe complications occurred. The mean hospital stay was 4.65 days. One patient (2.85%) was readmitted to the hospital within 90 days after discharge and died due to heart failure, with a 90-day mortality of 2.85%. Conclusions: Robotic liver resection for BCLM is feasible and safe when performed in experienced centers by surgeons who have completed the learning curve.
