Purpose: To assess the safety and potential equivalence of the use of hemosiderin compared to the Technetium-99 in sentinel lymph node biopsy in human breast cancer.
Methods: Non-random sample of 14 volunteer women diagnosed with breast cancer with primary tumors (T1/T2) and clinically tumor-free axilla were submitted to the identification of sentinel lymph node using hemosiderin obtained from autologous blood injected in the periareolar region 24h before surgery on an outpatient basis. Patients received preoperative subareolar intradermal injection of Technetium-99 in the immediate preoperative period. Patients were submitted to sentinel lymph node biopsy, with incision in the axillary fold guided by Gamma-Probe, dissection by planes until the identification of the point of maximum uptake of Technetium-99, identifying the marked nodes and their colors. All surgical specimens were sent for pathological and immunohistochemical study.
Results: The results showed no evidence of side effects and/or allergic and non-allergic reactions in patients submitted to SLNB with hemosiderin. The SLN identification rate per patient was 100%. SLNB identification rate per patient with hemosiderin was the same as that of Technetium, with a concordance rate of 100% between the methods.
Conclusion: Hemosiderin is a safe dye that is equivalent to Technetium in breast sentinel lymph node biopsy.

Purpose: The use of neoadjuvant systemic therapy for primary breast cancer can achieve tumor shrinkage, enabling less invasive surgical treatments, such as breast-conserving surgery instead of mastectomy, and sentinel node biopsy instead of axillary dissection. In recent years, an increasing number of studies have explored the use of primary systemic therapy for occult breast cancer with axillary presentation. These studies suggest that a more conservative approach, involving targeted axillary surgery could be cautiously proposed for occult breast cancer after neoadjuvant chemotherapy in selected patients.

Purpose: Sentinel lymph node biopsy (SLNB) is a staging procedure used to guide treatment for patients with breast cancer. Multiple variations in the SLNB technique have been described. We questioned how technique impacts the number of sentinel lymph nodes (SLNs) removed and associated complications.

Importance: The goal of surgical deescalation is to minimize tissue damage, enhance patient outcomes, and reduce the adverse effects often associated with extensive or traditional surgical procedures. This shift toward less invasive techniques has the potential to revolutionize surgical practices, profoundly impacting the methods and training of future surgeons.
Objective: To evaluate adoption of surgical deescalation within the field of gynecologic oncology using The National Cancer Database.

: In this paper, we investigate the association of glycoprotein 96 (GP96) and androgen receptor (AR) expression with clinicopathological factors, additional axillary lymph node burden, and their potential role in predicting 5-year overall survival (OS) and disease-free survival (DFS) in breast cancer (BC) patients with sentinel lymph node (SLN) involvement. We also explore the prognostic value of the presence of extranodal extension (ENE) in SLN. : We retrospectively enrolled 107 female patients with cT1-T2 invasive BC and positive SLN biopsy.
