Purpose: Side-specific systematic lymphadenectomy is suggested if sentinel lymph node (SLN) mapping failed in early stages endometrial cancer. This study aimed to evaluate the risk factors associated with failed mapping which may lead to modify SLN mapping technique, increase the success of SLN mapping and reduce the necessity of systematic lymphadenectomy.
Methods: Patients with early stage endometrial cancer were included in this study. All patients underwent SLN mapping with indocyanine green/near-infrared compatible surgical platforms. Indocyanine green was injected intracervical. "Bilateral mapping" and "failed bilateral SLN mapping (unilateral or bilateral failed mapping)" groups were compared for demographic, clinical, surgical, and pathological features.
Results: 101 cases were analyzed. The overall, unilateral, and bilateral SLN detection rates were 94.1%, 19.8%, and 74.3%, respectively. The failed (unilateral or no mapping) bilateral detection rate was 25.7%. Failed bilateral mapping rates were higher in patients with longer cervical and uterine longitudinal lengths, deep myometrial invasion and larger tumor size without statistical significance. Body mass index and operation type were not related with failed mapping. Increasing number of operations or injection of larger volume of indocyanine green (4 mL vs. 2 mL) did not improve mapping rate significantly.
Conclusion: Cervical indocyanine green injection may overcome the negative effect of obesity on bilateral mapping. Although there was a negative correlation trend between the longitudinal cervical and uterine lengths and bilateral mapping, this possible relation needs to be confirmed in further studies.

Sentinel lymph node (SLN) detection has been widely investigated in recent years as a part of the surgical staging of women with endometrial cancer (EC), gradually overtaking lymphadenectomy (LND) in this respect. In this study, thirty EC patients, assumed as stage I, were investigated using superparamagnetic iron oxide (SPIO) as a tracer for SLN detection followed by LND. The endpoints of this research were the proportion of successful SLN detection, the average number of SLNs per patient, the percentage of bilaterally detected SLNs, and the proportion of metastatic SLNs.

The aim was to evaluate the cost-effectiveness of sentinel lymph node (SLN) mapping in comparison to routine pelvic lymphadenectomy for lymph node assessment in patients with high-risk endometrial cancer (EC). A decision-analytic model was developed to compare SLN mapping with pelvic lymphadenectomy for guiding adjuvant therapy in patients with high-risk endometrioid and non-endometrioid EC, focusing on costs and health outcomes. The input data were obtained from systematic literature searches and expert consensus.

Objective: Treatment approaches for endometrial cancer became more personalized in the last decade, mainly due to two key advancements - sentinel lymph node (SLN) mapping and molecular classification. However, their prognostic interaction remains relatively unexplored.
Methods: This retrospective cohort study included patients with endometrial cancer, who underwent surgical treatment including SLN mapping at the Bern University Hospital, Switzerland.

Intro: Breast cancer is the leading cause of morbidity and mortality worldwide. Accurate sentinel lymph node (SLN) mapping is crucial for staging and treatment planning in early-stage breast cancer. Indocyanine green (ICG) has emerged as a promising agent for fluorescence imaging in SLN mapping.

Introduction: This study examined factors that affected sentinel lymph node (SLN) identification of patients with endometrial cancer having a preoperative estimation of low recurrent risk.
Methods: This study included 97 patients with endometrial cancer who attempted to identify SLN using a uterine cervical injection of technetium-99 m phytate under laparoscopic or robotic-assisted surgery at our institute. A preoperative single photon emission computed tomography (SPECT) and intraoperative gamma probe were used to detect hot nodes.
