Is preoperative imaging of sentinel lymph node in breast cancer necessary? A retrospective case control study.
Breast
December 2024
University Hospital for Gynecology, Pius Hospital, University Medicine Oldenburg, Carl von Ossietzky University Oldenburg, 26121, Germany.
Objective: The necessity of preoperative lymphoscintigraphy before intraoperative sentinel lymph node (SLN) identification is still unclear. The aim of the present study was to evaluate the impact of SLN imaging on intraoperative SLN detection in breast cancer patients.
Methods: Retrospective, comparative, single center study of patients with breast cancer stage pT1 and pT2 who underwent axillary staging.
Relevance of Sentinel Nodes in Atypical Territories in Surgically Treated Patients With T1-2N0 Oral Squamous Cell Carcinoma.

Service of Oral and Maxillofacial Surgery, Hospital Universitari Vall d'Hebron, Universitat Autònoma de Barcelona, Barcelona, Spain.
Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).
Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.

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.
Sentinel Lymph Node Detection in Early-Stage Oral Squamous Cell Carcinoma Using Magnetic Resonance Lymphography: A Pilot Study.

To assess the efficacy of magnetic resonance (MR) lymphography with gadobutrol contrast for sentinel lymph node (SLN) mapping in early-stage oral squamous cell carcinoma (OSCC). This pilot study compared the identification of SLNs by MR lymphography using a gadolinium-based contrast agent (gadobutrol) to conventional [Tc]Tc-nanocolloid lymphoscintigraphy (including single-photon emission computed tomography/computed tomography (SPECT/CT)) in 10 early-stage OSCC patients undergoing SLN biopsy. The patients initially underwent conventional lymphoscintigraphy following the peritumoral administration of indocyanine green [Tc]Tc-nanocolloid (120 megabecquerel; ~0.

Background: Sentinel lymph node biopsy (SNB) using radioisotopes is a standard method for assessing axillary lymph node status in patients with breast cancer. Although preoperative lymphoscintigraphy can estimate the number of sentinel lymph nodes (SNs), multiple radioactive SNs are often identified, even when lymphoscintigraphy reveals only one SN. Importantly, metastases are not always observed in the most radioactive SN (hottest SN).
