During recent years, an increasing number of patients with ipsilateral breast tumor recurrence (IBTR) and previous axillary surgery have undergone repeat sentinel lymph node biopsy (rSLNB). The influence of axillary nodal status on prognosis for IBTR patients remains unclear. This study aimed to evaluate the technical success rate, follow-up assessment, and prognostic value of rSLNB for patients with IBTR. ⋯ The prognostic impact of rSLN-positive versus rSLN-negative IBTR remains unclear. Further studies are needed to fill in the gap in the management of lymph nodes for patients with IBTR. However, based on the current evidence, rSLNB is feasible for 64% of patients, especially after previous SLNB. With a negative predictive value of 96.5%, rSLNB appears to be highly specific, with substantial advantages over ipsilateral ALND in IBTR.

Repeat sentinel lymph node biopsy (rSLNB) has increasingly been used in patients with ipsilateral breast tumor recurrence (IBTR). The safety in terms of regional disease control after this procedure remains unclear. This study evaluates occurrence of regional recurrence as first event in patients with IBTR and negative rSLNB, treated without additional lymph node dissection. ⋯ The risk of developing regional recurrence after negative rSLNB is low. The low relapse rate supports the safety of rSLNB as primary nodal staging tool in IBTR. The time has come for clinical guidelines to adopt rSLNB as axillary staging tool in patients with IBTR.

Although major cancer surgery at a high-volume hospital is associated with lower postoperative mortality, the use of such hospitals may not be equally distributed. ⋯ Differences in the use of CoC-accredited high-volume hospitals for major cancer surgery were seen nationwide and persisted over the duration of the study. Strategies to increase referrals and/or access to high-volume hospitals for African American and socioeconomically disadvantaged patients should be explored.
