Background: International guidelines are increasingly advocating for sentinel lymph node (SLN) omission in early breast cancer patients over 70 years. Studies examining such omission in patients with more aggressive phenotypes lobular subtype/grade 3/lymphovascular invasion (LVI) are lacking. The aim was to assess the rate of nodal positivity in these subgroups.
