Predicting Nonsentinel Node Status After Positive Sentinel Lymph Biopsy for Breast Cancer: Clinicians Versus Nomogram

摘要

With increasing frequency, breast cancer patients and clinicians are questioning the need for completion axillary lymph node dissection (ALND) in the setting of a positive sentinel lymph node (SLN). We previously developed a nomogram to estimate the likelihood of residual disease in the axilla after a positive SLN biopsy result. In this study, we compared the predictions of clinical experts with those generated by the nomogram and evaluated the ability of the nomogram to change clinicians’ behavior.
