This paper elaborates the Sentinel-2 image processing approaches used for the estimation of the population of an area of interest at Image CLEF Remote 2017 lab by the FabSpace 2.0 Darmstadt team. The task is introduced by Image CLEF Lab as a new pilot task in 2017 (Remote) which aims at exploring Copernicus Earth Observation data (i.e. Sentinel-2 satellite imagery) in order to estimate the popu...
Axillary node status is a major prognostic factor in early-stage disease. Traditional staging needs levels I and II axillary lymph node dissection. Axillary involvement is found in 10%-30% of patients with T1 (<2 cm) tumours. Sentinel lymph node biopsy is a minimal invasive method of checking the potential nodal involvement. It is based on the assumption of an orderly progression of lymph node ...
OBJECTIVE A significant morbidity risk is associated with axillary nodal dissections for breast cancer. Many treatment decisions are based on axillary nodal status. Lymphatic mapping and sentinel node biopsy have been investigated to determine if the histology of the sentinel node reflects the remaining lymph node basin. We describe the technical aspects of sentinel node lymphoscintigraphy for ...
OBJECTIVE Our objective was to determine the identification and the percentage of false negatives in sentinel node biopsies in patients with early breast cancer at the Hospital La Línea (Spain), during the period between November 2007 and September 2010. METHODS We collected 50 patients with early breast cancer, without clinical and ultrasonographic involvement of axillary nodes, from Novembe...
An essential prerequisite for a successful sentinel lymph node biopsy (SLNB) procedure is an accurate map of the pattern of lymphatic drainage from the primary tumor site in each patient. In melanoma patients, mapping requires high-quality lymphoscintigraphy, which can identify the actual lymphatic collecting vessels as they drain into the sentinel lymph nodes. Small-particle radiocolloids are ...
PURPOSE To evaluate and present our initial results of a new marker (hemosiderin) for mammary sentinel lymph node identification in an experimental model. METHODS Skins mapped like a lymphatic duct draining to the axilla in patients submitted to breast biopsy, in our mastology service, stimulated us to try it in an animal model (female dogs). Our theory was that some blood derivate (hemosider...
OBJECTIVES This paper discusses the influence of a para-areolar incision in the upper outer quadrant of the breast on the location of the sentinel lymph node in a canine model. METHODS The sentinel lymph node was marked with technetium-99, which was injected into the subareolar skin of the cranial breast. After the marker had migrated to the axilla, an arcuate para-areolar incision was perfor...
Background: The indocyanine green (ICG) fluorescence method is a newly developed technology to facilitate the sentinel node biopsy with the guidance of ICG fluorescence images. However, the surgical technique is still difficult, since the sentinel node cannot be indentified before skin incision and careful dissection of the subcutaneous lymphatic vessels is necessary. In this paper, an axillary...
BACKGROUND Sentinel node biopsy predicts accurate pathological nodal staging. The survival of node-negative breast cancer patients should be evaluated between the patients treated with sentinel node biopsy alone and those treated with axillary lymph node dissection. METHODS Ninety-seven patients with negative axillary nodes underwent sentinel node biopsy immediately followed by axillary lymph...
To evaluate the transmission of Mycoplasma hyopneumoniae and porcine reproductive and respiratory syndrome virus (PRRSV) by aerosol as either a single or mixed infection, 28 pigs were inoculated intratracheally with M hyopneumoniae on day 0 and infected intranasally with PRRSV on day 35; they were housed together in a barn. To assess the aerosol transmission of M hyopneumoniae as a single infec...
