The use of lymphoscintigraphy to localise the sentinel lymph node
Sentinel lymph node (SLN) biopsy is being used increasingly for staging early breast carcinoma in place of complete axillary lymph node dissection. The optimal method to identify the SLN and has not been clearly elucidated in the literature. A number of techniques have been proposed for identifying …

Sentinel Lymph Node Biopsy in a Resource Limited Setting: A Retrospective Comparison of Sentinel Lymph Node Biopsy before and after the introduction of SentiMag at an Academic Breast Unit
Background: Sentinel lymph node biopsy (SLNB) is performed for the staging and prognostication of breast cancer in cases with a clinically and radiologically negative axilla. Using blue dye and a radioactive colloid injection is considered the gold standard for SLNB. This study aims to evaluate the …

Experience using a small field of view gamma camera for intraoperative sentinel lymph node procedures
Staging is critical in the management of cancer. Sentinel lymph node (SLN) biopsy is one method used in the assessment of cancer spread. SLN procedures are standard practice in the management of some cancers although; these procedures have only recently been developed and refined. SLN procedures …

Completion Lymph Node Dissection or Observation for Melanoma Sentinel Lymph Node Metastases: A Decision Analysis
… To determine whether melanoma patients with sentinel lymph node (SLN) metastases should undergo completion lymph node dissection (CLND). Background: Randomized trial results comparing CLND with observation for patients with SLN metastases are not available. Methods: We developed a Markov …

Analysis of clinical and pathological outcomes of sentinel lymph node biopsy in the SNAC Trial.
Sentinel Lymph Node Biopsy (SLNB) has become the standard procedure to assess the status of the lymphatic drainage in early stages of breast cancer. Currently, SLNB has replaced Complete Axillary Dissection (CAD) when the lymph nodes are clinically negative. The detection of a Sentinel Lymph Node …

Sentinel lymph-node radiodetection in breast cancer : results of a clinical study and development of a quantitative approach
… Studie wertet die Anwendung eines Wächterlymphknotenkonzepts bei der Behandlung von Brustkrebs (bis T 2) bei 142 Patientinnen aus. Bei allen erfolgte eine präoperative Sonographie sowie eine planare Lymphszintigraphie mit Markierung der Lokalisation des Wächterlymphknotens auf der Haut und …

Sentinel node biopsy for the clinically N₊ & N₀ neck in squamous carcinoma of the head and neck
… of the study were to determine the accuracy of Sentinel Lymph Node Biopsy (SLNB) in head and neck squamous cell carcinoma (SCC); to determine its role in the approach to the clinically N+ neck in a Developing World setting; and its accuracy as an indicator of regional lymph node status in the …

Goggle Augmented Imaging and Navigation System for Fluorescence-Guided Surgery
… usually involves tumor resection and sentinel lymph node biopsy for cancer staging. Surgeons rely on their vision and touch to distinguish healthy from cancer tissue during surgery, often leading to incomplete tumor resection that necessitates repeat surgery. Sentinel lymph node biopsy …

Dual-modality thermoacoustic and photoacoustic imaging
… showed the feasibility of noninvasive in vivo sentinel lymph node imaging in a rat model. We have also developed and demonstrated molecular photoacoustic imaging using unique "soft-type" colloidal gold nanobeacons: GNBs) in the near-infrared region. GNBs represent a novel class of stable, …

Lymph node metastasis in auricular squamous cell carcinoma
… of the auricle has an unusually high rate of lymph node metastases when compared to similar tumours at other sites. The lymph nodes affected are close to the base of the skull and in the neck. Development of metastasis carries a poor prognosis and most patients will subsequently die of failure …

Innovating surgery for oral squamous cell carcinoma with targeted fluorescent and magnetic tracers
… its high propensity to metastasise to regional lymph nodes (LN)s. It is well-established that margin status and the presence of LN metastases are two of the most important factors affecting prognosis. While patient and tumour factors cannot be changed after presentation, margin control during …

Semiconductor nanocrystals : synthesis, mechanisms of formation, and applications in biology
… in biological systems from cellular labeling to sentinel lymph node mapping are demonstrated. In addition, we present new methods for doping InAs QDs in order to control carrier type through the introduction of acceptor defects such as cadmium. The synthesis and characterization of n and p type …

Statistical aspects of elastic scattering spectroscopy with applications to cancer diagnosis
… For the application of ESS to diagnosis of sentinel lymph node metastases in breast cancer, an automated ESS scanner was developed to take measurements from a larger area of tissue to produce ESS images for cancer diagnosis. Problems arise due to the existence of background area in the image …

Texaphyrin Architectures for Biomedical Applications
… a VX-2 head and neck tumour bearing rabbit for sentinel lymph node (SNL) mapping suggest Mn-nanotexaphyrin may serve as a contrast agent in lymphoscintigraphy procedures. Finally, the photophysical properties of texaphyrins were analyzed by creating a large library of metallotexaphyrin-antenna …

Periocular malignancy.
… from interventions such as strict regional node surveillance or sentinel lymph node biopsy. Once surgical excision is performed, the primary goal of eyelid reconstruction is ocular protection. Due to the unique structure of the eyelid, reconstruction of significant defects must replace both …

Novel Plasmonic Nanostructures for Applications in Sensing, Imaging, and Controlled Release
… a novel class of optical tracers for noninvasive sentinel lymph node: SLN) imaging by photoacoustic: PA) tomography. The transport kinetics of Au nanocages in a lymphatic system was evaluated by PA imaging on the axillary region of a rat. Several experimental parameters, including the injection …

Tissue Oxygen Imaging for Non-invasive Metastasis Detection
… treatment plans and improving survival rates. Sentinel lymph node biopsy is the gold standard for metastasis detection for many cancers. It involves injecting a blue dye called methylene blue and/or a radiocolloid at the primary tumor site and identifying the lymph nodes to which it drains. …
