PubMed, EMBASE, the Cochrane library, and online registers were searched for articles comparing SLNB alone vs. ALND for metastasis-positive SLN. Articles were evaluated for risk of bias using Cochrane\u2019s revised tool (RoB). The main summary measures using the random effects model were hazard ratio and risk ratio.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Seven RCTs were included in the meta-analysis. Overall survival and DFS were superior in the SLNB group compared to the ALND group. Locoregional recurrence and mortality were comparable between both the groups.

However, the inclusion of studies that did not differentiate between micrometastases and macrometastases may introduce bias, particularly when assessing the impact of RNI. The role of RNI remains debated specially in those with macrometastases, and future research should focus on stratified analyses to clarify this. While SLNB represents a viable alternative to ALND, further trials are needed to define the optimal role in subgroups with high-risk tumor biology.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11782234251335409","type":"journal-article","created":{"date-parts":[[2025,5,8]],"date-time":"2025-05-08T05:03:59Z","timestamp":1746680639000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Sentinel Lymph Node Biopsy vs. Axillary Lymph Node Dissection for Early-Stage Breast Cancer and Sentinel Lymph Node Metastasis: An Updated Systematic Review and Meta-Analysis With Special Focus on Locoregional Recurrence and Regional Node Irradiation"],"prefix":"10.1177","volume":"19","author":[{"given":"Sanjit Kumar","family":"Agrawal","sequence":"first","affiliation":[{"name":"Breast Surgical Oncology, Tata Medical Center, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
