AbstractRobot-assisted axillary lymph node dissection (RALND) has been proposed to improve surgical and oncological outcomes for patients with breast cancer. To perform a systematic review of current literature evaluating RALND in patients with invasive breast cancer. A systematic search was performed in accordance with the PRISMA guidelines. Studies outlining outcomes following RALND were included. Two studies involving 92 patients were included in this review. Of these, 41 underwent RALND using the da Vinci© robotic system (44.57%), and 51 underwent conventional axillary lymph node dissection (CALND) (55.43%). There was no significant difference observed with respect to intra-operative blood loss or duration of procedure in those undergoing CALND and RALND (P > 0.050). One study reported a significant difference in lymphoedema rates in support of RALND (6.67% vs 26.67%, P = 0.038). Overall, data in relation to postoperative fat necrosis (10.00% vs 33.33%, P = 0.028), wound infection rates (3.33% vs. 20.00%, P = 0.044), and wound ≤ 40 mm in length (63.63% vs. 19.05%, P = 0.020) supported RALND. Oncological outcomes were only reported in one of the studies, which concluded that there was no local or metastatic recurrence in either group at 3-month follow-up. These provisional results support RALND as a safe alternative to CALND. Notwithstanding, the paucity of data limits the robustness of conclusions which may be drawn surrounding the adoption of RALND as the standard of care. Further high-quality studies are required to ratify these findings.© 2023. The Author(s), under exclusive licence to Royal Academy of Medicine in Ireland.
