Impact of Micrometastases in the Sentinel Node of Patients With Invasive Breast Cancer

Abstract

Patients with micrometastatic tumor deposits, pN0(i+) or pN1mi, do not seem to have a worse 8-year DFS or OS compared with SN-negative patients. As expected, there was a significant decrease in 8-year DFS and OS in patients with pN1 disease in the SN.
