Fig. 2From: Outcomes of sentinel node biopsy according to MRI response in an association with the subtypes in cN1–3 breast cancer after neoadjuvant systemic therapy, multicenter cohort studyThe rates of complete MRI response. In the GSH-YCC cohort, 207 patients had HR+ HER2− breast cancer and 181 patients had HER2+ breast cancer (n = 181). Of the 388 patients, 55 (14.2%) were complete MRI responders, 25 (12.1%) of 207 patients in HR+ HER2−, and 30 (16.6%) of 181 patients in HER2+ or TNBC. In the validation cohort (AMC-SMC) consisting of 288 patients with HER2+ or TNBC, 47 (17.7%) patients achieved complete MRI response after NAST.
