Objectives: The purpose of this study was to report on the feasibility of laparoscopic sentinel lymph node (SLN) staging using indocyanine green (ICG) in the management of endometrial cancer.
Study Design: We retrospectively evaluated the charts of presumed, clinical stage I endometrial cancer patients who underwent robotic-assisted surgery that incorporated mapping with ICG and SLN dissection from January 2016 until February 2017. Patient demographics, operative characteristics (e.g., complications, lymph node counts) and pathology data were evaluated.
Results: There were 87 patients who were included in the study. A total of 370 lymph nodes were removed, of which 245 were SLNs; unilateral and bilateral mapping of the SLNs was achieved in 84 (96.5%) and 71 (81.6%) of subjects, respectively. There were 10 (11.5%) patients who had metastatic disease identified within 22 (5.9%) of the total (n = 370) lymph nodes extracted, 19 (7.7%) of which were sentinel lymph nodes. We did not observe any intraoperative complications.
Conclusion: The results from our study suggest that minimally invasive SLN staging using ICG is a feasible procedure that is potentially effective at detecting metastases, which may ultimately attenuate the incidence of surgical morbidity.

Background: Sentinel lymph node biopsy (SLNB) using radioisotope tracer plus blue dye is the gold standard after neoadjuvant chemotherapy (NAC) in initially cN1 breast cancer patients, but clinical use still has limitations. This study aims to examine diagnostic performance of dual indocyanine green (ICG) and methylene blue tracing for SLNB in patients who have completed NAC for breast cancer with initially cN1 disease.
Methods: Adult women (20-80 years of age) scheduled to undergo NAC for biopsy-proven cT0-3N1M0 primary invasive breast cancer were consecutively enrolled in this prospective, multicenter, cohort study.

Background: In patients with breast cancer staged ypN1 after neoadjuvant chemotherapy (NAC), there is limited evidence-based guidance regarding exemption from axillary lymph node dissection (ALND).
Methods: This study analyzed ypN1 breast cancer patients post-NAC from the Surveillance, Epidemiology, and End Results databases. Patients were categorized into the breast-conserving surgery (BCS) group and the total mastectomy (TM) group, and further divided by the number of positive lymph nodes (LNs).

Objective: To explore the clinical efficiency of using the sentinel lymph node (SLN) imaging agent Tc-rituximab for lymphoscintigraphy and SLN biopsy (SLNB) in oral squamous cell carcinoma (OSCC) patients.
Methods: A retrospective study was conducted on 23 patients with OSCC who underwent Tc-rituximab lymphoscintigraphy and SLNB. The cohort comprised 16 men (69.

Male breast cancer (MBC) is a rare disease, accounting for less than 1% of all breast cancer cases. Sentinel lymph node biopsy (SLNB) has emerged as a less invasive alternative to axillary lymph node dissection (ALND) for axillary staging in breast cancer, offering reduced morbidity and comparable accuracy. However, the application of SLNB in MBC remains underexplored, with limited male-specific data and treatment protocols often extrapolated from female breast cancer studies.

Purpose: The optimal method for axillary staging in patients with initially node-positive breast cancer after NACT remains unclear.
Methods: We conducted a prospective, single-center trial to investigate the diagnostic performance of sentinel lymph node biopsy (SLNB) combined with wire localized lymph node biopsy (WLNB) of the clip-marked node as an axillary staging technique in patients with node-positive breast cancer after neoadjuvant chemotherapy (NACT).
Results: A total of 233 patients were enrolled, 208 of whom were included in the analysis.
