Prospective study found that peripheral lymph node sampling reduced the false-negative rate of sentinel lymph node biopsy for breast cancer.

CONCLUSIONS: The FNR of SLNB was associated with the number of SLNs. For patients with ≤3 detected SLNs, PLN sampling can reduce the FNR of SLNB to an acceptable level of less than 5%. Because of the existence of the "skip metastasis" and distinct metastasis patterns, the FNR of SLNB cannot be completely eliminated. PMID: 27044285 [PubMed - in process]
