NR4A1 and breast cancer: Furthermore, after PSM of the pN1 stage patients, SLNB was associated with a significantly worse BCSS in hormone receptor negative (HR-) patients (HR = 1.536, 95%CI = 1.213-1.946, <i>p <</i> 0.001), but not in the hormone receptor positive (HR+) group (HR = 1.150, 95%CI = 0.986-1.340, <i>p</i> = 0.075).<h4>Conclusion</h4>In our study, ALND does not yield superior survival compared with SLNB for elderly patients with pN1 stage HR+ breast cancer.
