Background: Sentinel lymph node biopsy (SLNB) should be performed in patients with ductal carcinoma in situ (DCIS) undergoing mastectomy. Yet, the same logic is controversial in the setting of prophylactic mastectomy.
Methods: Surgeons were surveyed as to their practices. Statistical analyses were performed to identify associated factors.
Results: 238 surgeons responded to the survey. 73.1% of respondents stated they would always perform SLNB in the setting of mastectomy for DCIS, but only 6.6% would always do so in the prophylactic setting. While generally perceived that the rate of SLN positivity in the setting of pure DCIS and prophylactic mastectomy was <5% (96.9% and 99.5%, respectively), 61.8% of surgeons who reported "always" performing SLNB in the setting of DCIS treated with mastectomy stated they "never" performed a SLNB for prophylactic mastectomy.
Conclusion: SLNB practice patterns for these low risk settings are disparate. Consensus is required to rationalize practice.

The use of dual-tracer contrast agents in clinical applications, such as sentinel lymph node (SLN) identification, offers significant advantages including enhanced accuracy, sensitivity, as well as comprehensive and multimodal visualization. In the current clinical practice, SLNs are typically marked prior to surgical resection by multiple and sequential injections of two tracers, the radioactive tracer and methylene blue (MB) dye. This imposes physical and psychological burden on patients and medical staff.

Purpose: The purpose of this study was to evaluate the feasibility and safety of indocyanine green (ICG) fluorescence as an alternative to traditional sentinel lymph node biopsy (SLNB) techniques in breast cancer (BC) patients undergoing neoadjuvant chemotherapy (NAC). Specifically, the study aimed to assess sentinel node identification rates and the effectiveness of ICG in axillary staging without the use of radioactive tracers.
Methods: This retrospective study included 71 BC patients treated with NAC, who underwent SLNB using ICG fluorescence between 2020 and 2024.

Rhabdomyosarcoma (RMS) tumors arise from mesenchymal tissue and represent half of pediatric sarcomas, which in turn make up 7% of pediatric tumors. Advances in local control therapy of RMS have improved outcomes after surgical resection of the primary tumor, either before or after induction chemotherapy, even in the setting of metastatic disease. The utilization of diagnostic core needle and sentinel node biopsy techniques for lymph node staging are becoming more widely used.

Introduction: The management of malignant melanomas often involves performing a sentinel lymph node biopsy (SLNB) aided by imaging with lymphoscintigraphy. Whether lymphoscintigraphy should be performed on the same day as the SLNB operation (SD) or the day before (DB) surgery remains debated. This study aims to summarise existing evidence regarding the impact of the relative timings of lymphoscintigraphy and SLNB on clinical outcomes in melanoma.
