Background And Objectives: The objective of this study is to establish the detection rate of sentinel lymph node (SLN) biopsies and to determine the sensitivity and false-negative rate of SLN biopsies compared with those of systematic pelvic and para-aortic lymphadenectomies in endometrial cancer.
Methods: This prospective cohort study enrolled patients with endometrial cancer who were scheduled for surgical staging. Patients with a history of chemotherapy or radiotherapy, an abnormal liver function test, or an allergy to indocyanine green (ICG) were excluded. All patients underwent surgical staging with an ICG injection at the cervix. SLNs were identified by a near-infrared fluorescent camera. All SLNs were sent to a pathologist for ultrastaging.
Results: From November 2019 to June 2023, 142 patients underwent SLN mapping and surgical staging. SLNs were not detected bilaterally in 8 patients. The detection rate of the SLN biopsies in this study was 91.2%. Thus, the accuracy of the SLN biopsies was 97.6%. The sensitivity for finding metastatic SLNs was 84.2%, with a negative predictive value of 97.22%.
Conclusions: A SLN biopsy in endometrial cancer has a high detection rate and high accuracy. However, surgical expertise and a learning curve are required.

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.

Objective: This retrospective study aimed to evaluate the predictive value of the preoperative dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion-weighted imaging (DWI) findings of mass lesions for predicting sentinel lymph node (SLN) metastasis in early breast cancer.
Methods: A total of 310 patients with suspicious mass lesions detected in preoperative MRI who subsequently underwent surgery and SLN biopsy (SLNB) between September 2015 and September 2022 were analyzed. The relationship between DCE-MRI and DWI findings and SLNB positivity was analyzed.

Parkinson's disease (PD) is a debilitating neurodegenerative disorder characterized by motor and non-motor symptoms, with limited effective treatment options. This study proposes a novel approach utilizing intranasal delivery of carbenoxolone (CBX) via chitosan-coated solid lipid nanoparticles (CS-coated SLNs) to manage PD symptoms by enhancing CBX delivery and brain targeting. Formulated CS-coated SLNs exhibited favorable quality attributes including particle size (164 ± 0.

: In this paper, we investigate the association of glycoprotein 96 (GP96) and androgen receptor (AR) expression with clinicopathological factors, additional axillary lymph node burden, and their potential role in predicting 5-year overall survival (OS) and disease-free survival (DFS) in breast cancer (BC) patients with sentinel lymph node (SLN) involvement. We also explore the prognostic value of the presence of extranodal extension (ENE) in SLN. : We retrospectively enrolled 107 female patients with cT1-T2 invasive BC and positive SLN biopsy.

The pretherapeutic assessment of axillary lymph node status is crucial in staging early breast cancer patients, significantly influencing their further treatment and prognosis. According to current guidelines, patients with clinically unsuspicious axillary status regularly undergo a biopsy of sentinel lymph nodes (SLNs), whereby metastasis is detected in up to 20% of cases. In recent years, the use of shear wave elastography (SWE) has been studied as an additional ultrasound tool for the non-invasive assessment of tumors in the breast parenchyma and axillary lymph nodes.
