2. 1. Sentinel Node in Clinical Practice : Implications for Breast Cancer Treatment and Prognosis

   Author : Yvette Andersson; Leif Bergkvist; Jan Frisell; Jana de Boniface; Robert Mansel; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breast cancer; sentinel node; micrometastases; survival; non-sentinel node metastases;

   Abstract : The introduction of sentinel lymph node biopsy (SLNB) has conveyed several new issues, such as the risk of false negativity, long-term consequences, the prognostic significance of micrometastases and whether ALND can be omitted in sentinel lymph node- (SLN) positive patients.Archived SLN specimens from 50 false negative patients and 107 true negative controls were serially sectioned and stained with immunohistochemistry.

   Abstract : Earth Observation (EO) satellites have great potential in wildfire detection and assessment at fine spatial, temporal, and spectral resolutions. For a long time, satellite data have been employed to systematically monitor wildfire dynamics and assess wildfire impacts, including (i) to detect the location of actively burning spots, (ii) to map the spatial extent of the burn scars, (iii) to assess the wildfire damage levels.

   Abstract : Wildfires have coexisted with human societies for more than 350 million years, always playing an important role in affecting the Earth's surface and climate. Across the globe, wildfires are becoming larger, more frequent, and longer-duration, and tend to be more destructive both in lives lost and economic costs, because of climate change and human activities.

6. 4. Sentinel Node Biopsy in Breast Cancer : Clinical and Immunological Aspects

   Author : Jana de Boniface; Leif Bergkvist; Annika Håkansson; Omgo Nieweg; Uppsala universitet; []
   Keywords : Surgery; breast cancer; tumour immunology; sentinel node biopsy; CD3-zeta; CD28; Kirurgi;

   Abstract : The most important prognostic factor in breast cancer is the axillary lymph node status. The sentinel node biopsy (SNB) is reported to stage the axilla with an accuracy > 95 % in early breast cancer. Tumour-related perturbation of T-cell function has been observed in patients with malignancies, including breast cancer. READ MORE

7. 5. Sentinel Node Biopsy for Breast Cancer : Aspects and evolution

   Author : Andreas Karakatsanis; Fredrik Wärnberg; Peter Stålberg; Helena Olofsson; Lisa Rydén; Uppsala universitet; []
   Keywords : Breast Cancer; Sentinel Node Biopsy; Superparamagnetic Iron Oxide;

   Abstract : Sentinel Node Biopsy (SNB) in clinical practice was pivotal to the shaping of modern diagnosis, staging and treatment of patients with breast cancer. The use of radioisotope (RI) and blue dye (BD) has led to high detection rates with low false negatives, but delivery-of-care limitations connected to these tracers as well as the need for methods addressing new clinical conundrums delineates the urge for new tracers with comparable performance, easier logistics and, ideally expanded implementations.
