SLNB can be safely omitted in elderly patients with T1, HR-positive, invasive ductal carcinoma tumors, but may still provide important information affecting treatment. Adjuvant hormone therapy significantly improved overall survival. SLN-negative patients had better overall survival and less distant recurrence (both p < 0.0001). In both the overall cohort and the HR-positive subset, SLN status significantly affected the use of adjuvant chemotherapy, although no significant effect on recurrence was observed. Characteristics of the HR-positive subset were similar. Median number of SLNs obtained was 2 (range 0-12) and median number of positive SLNs was 0 (range 0-8). Most tumors were T1 (72%), N0 (69%), invasive ductal (77%), without lymphovascular invasion (88%), estrogen receptor-positive (88%) and progesterone receptor-positive (75%), and human epidermal growth factor receptor 2 (HER2)-negative (88%) treated with lumpectomy (71%). Of 500 patients, 345 (69%) were SLN-negative. Outcomes were analyzed using the Kaplan-Meier method and univariable analysis, and were compared using log-rank tests. One of the most exciting and talked about new surgical techniques in breast cancer surgery is the sentinel lymph node biopsy. Patients were compared according to SLN status with subset analysis of HR-positive patients. We collected clinicopathologic characteristics and treatment data. We examined the effect of SLNB on treatment and outcomes in this population.Ī single-institution retrospective review of consecutive cN0 women ≥ 70 years of age who received SLNB was performed. SNB rates in this cohort were lower than in non-pregnant breast cancer patients.The Society of Surgical Oncology's Choosing Wisely ® guidelines recommend against routine sentinel lymph node biopsy (SLNB) in clinically node-negative (cN0), hormone receptor (HR)-positive breast cancer patients aged ≥ 70 years. Methods We carried out a comprehensive literature review focusing on the journey of the use of sentinel lymph node biopsy (SLNB) in breast cancer from. To be accepted as a standard of care, it had to pass successfully through a long journey which started in the early 1990s. This is one of the largest reported experiences of SNB during pregnancy however, numbers remain limited. Background Sentinel lymphadenectomy has replaced axillary lymph node dissection as a staging tool in early breast cancer. SNB in pregnant breast cancer patients appears to be safe and accurate using either methylene blue or 99-Tc. Among patients who underwent SNB, there were 25 liveborn infants, of whom 24 were healthy, and 1 had cleft palate (in the setting of other maternal risk factors). At a median of 2.5 years from diagnosis, there was one locoregional recurrence, one new primary contralateral tumor, three distant recurrences, and one breast cancer death. As a result, management of patients with these cancers has been revolutionized. There were no SNB-associated complications. It has been validated that sentinel lymph node biopsy (SLNB) shows whether a patient’s breast cancer or melanoma has spread to regional lymph nodes. 99 m-Technetium (99-Tc) alone was used in 16 patients, methylene blue dye alone in 7 patients, and 2 patients had unknown mapping method. Of SNB patients, 8, 9, and 8 had SNB in the first, second, and third trimesters, respectively. Within a cohort of 81, 47 clinically node-negative patients had surgery while pregnant: 25 (53.2 %) SNB, 20 (42.6 %) upfront axillary lymph node dissection, and 2 (4.3 %) no lymph node surgery. Chart review was performed to tabulate patient/tumor characteristics, method/outcome of SNB, and short-term maternal/fetal outcomes. Patients who underwent SNB while pregnant were identified from a retrospective parent cohort of women diagnosed with breast cancer during pregnancy. This study evaluated efficacy and safety outcomes in pregnant breast cancer patients undergoing SNB. Sentinel lymph node biopsy (SNB) in pregnant women with breast cancer is uncommonly pursued given concern for fetal harm.
