Background Tumor-positive sentinel node biopsy (SNB) suggests a risk of nonsentinel node
metastases in breast cancer. This risk is lower after micrometastasis or isolated tumor cells …

BACKGROUND: The accurate prediction of nonsentinel node (NSN) metastasis in breast
cancer patients remains uncertain. METHODS: The medical records of 574 breast cancer …

Background In this multi-institutional prospective study, we evaluated whether we could
identify risk factors predictive for non-sentinel lymph node (non-SN) metastases in breast …

Background We have developed a new nomogram to predict the probability of a patient with
1–2 metastatic sentinel lymph nodes (SLNs) to present further axillary disease. Methods …

PURPOSE: Predictive factors of non-sentinel lymph node (NSN) involvement at axillary
lymph node dissection (ALND) have been studied in the case of sentinel node (SN) …

Background The usefulness of axillary lymph node dissection (ALND) in patients with
positive sentinel nodes (SN) is still an ongoing debate. Several nomograms have been …

Introduction Nomograms are used to predict the involvement of non-sentinel nodes (nSN) in
breast cancer. This study attempts to externally validate two of the more commonly used …

Background Axillary lymph node dissection (ALND) may not be necessary in women with
breast cancer who have micrometastasis in a sentinel node (SN), owing to the low risk of …

Hypothesis The presence of nonsentinel lymph node (NSLN) metastasis after having a
positive sentinel lymph node dissection finding is associated with tumor size and stage, the …

Axillary lymph node dissection (ALND) in breast cancer patients with positive sentinel nodes
is under debate. We aimed to establish two models to predict non‐sentinel node (NSN) …
