Editor—Kell and Kerin wrote about sentinel lymph node biopsy in breast cancer and melanoma. This is a staging procedure with a well established role in breast cancer, reducing the need for dissection of the axillary node. The indications and advantages for sentinel lymph node biopsy in melanoma are not confirmed, and it is certainly not the established treatment implied in the editorial. Sentin...

The sentinel lymph node was defined as the first lymph node to receive drainage from a primary cancer. The aims of this study were to investigate the efficacy of radiocolloid lymphoscintigraphy and of the hand-held gamma probe procedure for sentinel lymph node biopsy in papillary thyroid carcinoma and to evaluate these results in clinical staging. A total of 99 consecutive papillary thyroid car...

BACKGROUND The development of sentinel lymph node biopsy in breast cancer disease and the increasing of using adjuvant systemic therapy provide a rational reduction of axillary dissection in patients with Sentinel Lymph Nodes free from breast cancer cells. The aim of our study was to assess the state of the perisentinel lymph nodes removed and how these nodes can provide further information abo...

Lymphatic mapping and sentinel node biopsy were initially developed for nodal staging in the malignant melanoma population. Morton and colleagues developed a procedure that permits intraoperative identification of the sentinel lymph node, the first node in the lymphatic basin from which the primary tumor drains. If that sentinel node is negative for metastatic disease, the remaining nodes in th...

ESA's upcoming satellite Sentinel-2 will provide Earth images of high spatial, spectral and temporal resolution and aims to ensure continuity for Landsat and SPOT observations. In comparison to the latter sensors, Sentinel-2 incorporates three new spectral bands in the red-edge region, which are centered at 705, 740 and 783 nm. This study addresses the importance of these new bands for the retr...

BACKGROUND Experience on sentinel node mapping in ovarian tumors is very limited. We evaluated the sentinel node concept in ovarian tumors using intra-operativeTc-99m-Phytate injection and lymphoscintigraphy imaging. METHODS Thirty-five patients with a pelvic mass due to an ovarian pathology were included in the study. The radiotracer was injected just after laparotomy and before removal of t...

OBJECTIVE In the previous report, to simplify the synthesis and labelling procedures and to improve the biological properties, we developed a novel mannose receptor-binding agent, technetium-99m human serum albumin (99mTc-MSA), for sentinel lymph node detection. This study is the first clinical trial designed to test the reliability and feasibility of sentinel node detection using this new radi...

A pulley-block system for elevating sentinel chicken coops was designed to conduct mosquito-borne virus surveillance in the forest canopy. This modified design allows traditional captive sentinel bird cages to be hoisted easily to the desired height and lowered at regular intervals for routine maintenance and sampling of the flocks. The design specifications of this canopy system are modificati...

The objective of this research was to investigate the impact of seasonality on urban land-cover mapping and to explore better classification accuracy by using multi-season Sentinel-1A and GF-1 wide field view (WFV) images, and the combinations of both types of images in subtropical monsoon-climate regions in Southeast China. We obtained multi-season Sentinel-1A and GF-1 WFV images, as well as t...

Breast cancer is the most common type of cancer in women. The 5-year survival rate in patients with breast cancer ranges from 74 to 82 %. Sentinel lymph node biopsy has become an alternative to axillary lymph node dissection for nodal staging. We evaluated the detection of the sentinel lymph node and metastasis of the lymph node using contrast enhanced ultrasonography with Sonazoid. Between Dec...
