UNLABELLED Preoperative injection of radiocolloid for axillary sentinel node biopsy in breast cancer is uncomfortable for patients. This study evaluated the reliability of radiocolloid injection as determined by sentinel node identification rate and positive sentinel node biopsy rate, after the patient has been anesthetized in the operating room as compared with preoperative injection. METHOD...

This paper introduces a method for speculative execution, sentinel scheduling with recovery blocks, which is an improvement upon sentinel scheduling. This method is compared against speculative models that have been proposed previously. The hardware and compiler support needed for sentinel scheduling with recovery blocks is fully described. Quantitative results of speedup and code growth are pr...

Sentinel lymph nodes are mapped using (99m)Technetium, injected on day of surgery (1-day protocol) or day before (2-day protocol). This retrospective cohort study compares efficacy between the two protocols. Histopathology for all unilateral sentinel lymph node biopsies (March 2012-March 2013) in a single centre were reviewed. Number of sentinel lymph nodes, non-sentinel lymph nodes and patholo...

PURPOSE To investigate the safety and clinical utility of the sentinel node procedure in early-stage vulvar cancer patients. PATIENTS AND METHODS A multicenter observational study on sentinel node detection using radioactive tracer and blue dye was performed in patients with T1/2 (< 4 cm) squamous cell cancer of the vulva. When the sentinel node was found to be negative at pathologic ultrasta...

BACKGROUND The aim of this study was to evaluate whether MRI at 3 T with superparamagnetic iron oxide (SPIO) enhancement is an accurate and useful method for detecting metastases in sentinel nodes identified by CT-lymphography (CT-LG) in patients with breast cancer. The results were compared with those obtained using CT-LG alone and diagnosing metastasis according to size criteria. METHODS Pa...

BACKGROUND Any sentinel lymph node that receives lymph drainage directly from a primary melanoma site, regardless of its location, may contain metastatic disease. This is true even if the sentinel node does not lie in a recognized node field. Interval (in-transit) nodes that lie along the course of a lymphatic vessel between a primary melanoma site and a recognized node field are sometimes seen...

Sentinel-1B is the second of two C-Band Synthetic Aperture Radar (SAR) satellites of the Sentinel-1 mission, launched in April 2016—two years after the launch of the first satellite, Sentinel-1A. In addition to the commissioning of Sentinel-1B executed by the European Space Agency (ESA), an independent system calibration was performed by the German Aerospace Center (DLR) on behalf of ESA. Based...

The concept of sentinel lymph node biopsy in breast cancer surgery relates to the fact that the tumor drains in a logical way through the lymphatic system, from the first to upper levels. Therefore, the first lymph node met (the sentinel node) will most likely be the first to be affected by metastasis, and a negative sentinel node makes it highly unlikely that other nodes are affected. Because ...

Lymphatic mapping and sentinel lymphadenectomy is becoming an important surgical technique for assessing axillary status in breast cancer. In experienced hands, it can be successfully performed in >90% of cases. The morbidity of sentinel lymphadenectomy is minimal, considerably less than the 15%-20% rate of complications associated with axillary lymph node dissection. Moreover, excision of the ...

The prognostic value of the sentinel lymph node in Merkel cell carcinoma (MCC) has been examined previously in heterogeneous retrospective studies. The current retrospective study included a homogeneous population of patients with a localized MCC, all staged with sentinel lymph node biopsy. Factors associated with 3-year progression-free survival were analysed using logistic regression. The sen...
