PURPOSE Hand-held gamma-probes are used for the identification of the sentinel node location during intra-operative radio-guided surgeries. Various gamma-probes, which use different detectors, collimation and electronics, are available on the market. Spatial resolution, sensitivity and angular resolution of the probes are believed to be determinant for the success of the identification of the s...

This paper proposes the concept of sentinel rules for multi-dimensional data that warns users when measure data concerning the external environment changes. For instance, a surge in negative blogging about a company could trigger a sentinel rule warning that revenue will decrease within two months, so a new course of action can be taken. Hereby, we expand the window of opportunity for organizat...

BACKGROUND The prognostic value and clinical implication of micrometastases and isolated tumor cells (ITCs) in sentinel lymph nodes are still not clearly defined. This study was designed to collect clinical pathological data in our Institution. PATIENTS AND METHODS Twenty-five cases of micrometastases and nine cases of ITCs were identified among 1,000 sentinel lymph node biopsies performed at...

The main factor that affects the prognosis of patients with head and neck cancer (HNC) is regional lymph node metastases. For this reason, the accurate evaluation of neck metastases is required for neck management. This study investigates the sentinel lymph node identification and the accuracy of the histopathology of the sentinel lymph node in patients with HNC. Eleven patients with histologic...

BACKGROUND To report our experience with sentinel lymph node biopsy for staging patients with conjunctival melanoma. METHODS A prospective review of patients with conjunctival melanoma who underwent sentinel lymph node biopsy at St Bartholomew's Hospital from May 2008 to May 2012. The selection criterion for sentinel node biopsy depended on the tumour thickness (≥2 mm) and location of the con...

BACKGROUND For accurate nodal staging, all blue and radioactive lymph nodes should be sampled during the sentinel lymph node biopsy for breast cancer. We report a case of anomalous drainage in which one of the sentinel lymph nodes was unexpectedly found in the level III axillary space. CASE PRESENTATION A 40-year-old female underwent mastectomy for extensive high-grade ductal carcinoma in-sit...

Fraud, waste and abuse are significant problems in major industries such as healthcare and manufacturing, particularly when third party payers such as Medicare are involved. Current practices for auditing fraudulent activity are based on scoring models used to select practitioners or claims that are likely to be fraudulent. These models ignore the “sentinel effect” that arises from the behavior...

List of Papers This thesis is based on the following papers, which are referred to in the text by their Roman numerals. Serial sectioning of breast cancer sentinel nodes does not significantly improve false negativity rate.

The arboviral surveillance program in California depends in part on sentinel chickens to detect western equine encephalomyelitis virus, St. Louis encephalitis virus, and West Nile virus activity. From 2000 through 2002, 1,578 serum specimens from 34 sentinel flocks in northern and southern California were tested for antibodies to Culex tarsalis salivary gland antigens. Sentinel chickens that we...

PURPOSE We aimed to develop and translate a CD20-antigen-targeted radiopharmaceutical, Technetium-99 m-labeled (99mTc) rituximab, for sentinel lymph node (SLN) detection. METHODS 99mTc-rituximab was synthesized and tested for stability in human serum. The binding affinity to CD20 was evaluated in Raji cells by flow cytometric analysis. Biodistribution and sentinel node mapping were carried ou...
