Introduction: False-negative sentinel lymph node biopsy (SLNB) rates following neoadjuvant chemotherapy (NACT) in initially node-positive (cN1/2) breast cancer patients are high, but decrease when lymph nodes are clipped, ≥3 sentinel lymph nodes (SLN) are removed or dual-tracer localization (radioisotope and blue dye) is used. Radiotracer, however, is often unavailable and outcomes with blue dye alone are unknown.

Materials And Methods: Initially cT1-4, cN1/2 patients treated with NACT in 2013-2023 who underwent SLNB using blue dye alone were evaluated regarding SLN identification, axillary recurrence, disease-free and overall survival rates.

Introduction: Despite the lack of randomised evidence, there is a current trend towards omitting axillary surgery in cases of positive sentinel lymph node (SLN) following neoadjuvant chemotherapy (NACT). This study evaluated practice patterns of Brazilian breast surgeons when managing positive SLN following NACT.

Methods: This was a nationwide electronic survey of breast surgeons affiliated with the Brazilian Society of Mastology.

The 17th edition of the St Gallen International Breast Cancer Conference was held in March 2021 in an entirely virtual mode. More than 3,300 participants took part in this important bi-annual critical review of the 'state of the art' in the multidisciplinary care of early-stage breast cancer (BC). Seventy-four experts from all continents discussed and commented on the previously elaborated consensus questions as well as numerous interrogations on early-BC diagnosis and treatment asked by the audience.

Breast cancer is a complex disease, and accurate systemic staging is an essential aspect of the evaluation of a patient with newly diagnosed breast cancer. Considering that the chance of having metastatic disease at breast cancer diagnosis is different in each patient and depends on a variety of anatomic and biologic factors, it is crucial to understand that some populations may benefit from more intensive staging because their pretest probability of metastatic disease is higher than that of the average patient. Identifying these patients with de novo stage IV breast cancer is associated with substantial prognostic and therapeutic implications.

Article Synopsis
  • Neoadjuvant endocrine therapy (NET) has shown effectiveness in treating ER-positive/HER2-negative breast cancer in clinical trials, but its real-world adoption remains low; this study aimed to provide insights from actual practice.
  • A cohort of 146 postmenopausal women undergoing NET was evaluated, with findings indicating a median age of 67 and a majority having early-stage disease, treated predominantly with aromatase inhibitors for about 21 weeks without any tumor progression.
  • The study found that NET is both effective and safe, suggesting that factors like postmenopausal status and low-risk tumor characteristics should be considered when selecting patients for this therapy.

The aim of this study was to evaluate 10-year local control and overall survival of IORT for early breast cancer treatment. We analyzed 68 patients submitted to breast conservative surgery and IORT, in the accelerator room of the Radiotherapy Service in South Brazil. In the long-term follow-up, we had 17.
