Repeat Sentinel Lymph Node Biopsy in Ipsilateral Breast Tumor Recurrence

According to the standard treatment guidelines established until recently, in the case of ipsilateral breast tumor recurrence without systemic metastasis, salvage mastectomy or lumpectomy can be performed when either partial or whole breast radiation therapy is possible. On the other hand, there are currently no standard treatment guidelines for axillary treatment, and the evidence for this is limited. Axillary lymph node metastasis was reported to occur in about 26% of breast cancer patients who had negative sentinel lymph nodes from previous surgery for primary breast cancer and only local recurrence occurred. It is still important in the decision of treatment or adjuvant radiation therapy. However, it is known that most of the patients with ipsilateral breast recurrence do not have axillary lymph node metastasis. Therefore, performing axillary axillary surgery in all of these patients does not help the patient's survival in many cases, but rather can lead to complications such as lymphedema and seroma and postoperative wound infection. A question about the implementation of axillary lymph node resection has been raised and for this reason, it is necessary to study whether surveillance lymph node biopsy is still effective in patients with recurrence in the ipsilateral breast. Most of the studies on ipsilateral breast tumor recurrence without systemic metastasis reported to date are case reports or small retrospective studies. In addition, the combined meta-analysis also ha…
