Abstract
Background/Objectives: Recent advancements in breast cancer treatment have led to increased survival rates, prompting a shift towards addressing breast cancer-related lymphedema (BCRL). Despite the evolving role of lymphatic surgery in breast reconstruction, there is limited literature evaluating the current role of lymphatic surgery in breast reconstruction. This review aims to evaluate the state of lymphatic surgery in breast reconstruction, analyzing surgical techniques and proposing a multi-institutional algorithmic approach. Methods: Through a search and screening of literature, data regarding the study type, type of operation (bypass, pLVB/ILR/LYMPHA, VLNT, or a combination of treatments), and clinical outcomes were collected. Results: The systematic review included 184 studies. Overall, the number of publications on lymphatic surgery increased from 4.4 per year (2010-2016) to 21.1 per year since 2017. The most published procedure was vascularized lymph node transfer (34.6%), followed by preventive lymphatic surgery (31.4%), therapeutic lymphovenous bypass (23.3%), and combined breast and lymphatic reconstruction (10.7%). While VLNT was the most published procedure, preventive surgery has been the most published topic since 2020, with 11.7 articles per year since. Similarly, there has been an increase in studies on combined lymphatic surgery and breast reconstruction in the last five years, with 16 articles published. Conclusions: The role of lymphatic surgery in breast cancer patients is evolving, with an increasing emphasis on preventive procedures and combined reconstructive approaches. However, our study shows that the current literature is predominantly based on lower-level evidence, highlighting the need for more randomized controlled trials to establish stronger clinical recommendations.
