Sentinel node dissection as definitive treatment for node negative breast cancer patients

European Journal of Surgical Oncology (EJSO), 2003
Negative sentinel node may predict tumour-free axillary nodes in breast cancer. We report the performance of sentinel node dissection at our Institution.We analysed data from 212 consecutive women with primary invasive breast tumours less than 3 cm in diameter and no axillary lymphadenopathy who underwent radioguided sentinel node dissection by means ...

A simplified CT-based definition of the lymph node levels in the node negative neck

Radiotherapy and Oncology, 1999
Using three dimensional (3D) conformal radiotherapy (CRT) techniques for elective neck irradiation (ENI) may allow for local disease control to be maintained while diminishing xerostomia by eliminating major salivary glands (or parts thereof) from the treatment portals.

Network Defensive Strategy Definition Based on Node Criticality

2019 IEEE International Conference on Systems, Man and Cybernetics (SMC), 2019
In this paper we develop a novel approach to identify the best policy to allocate protection resources to raise the overall network robustness to node disruption. The proposed methodology is based on the identification of the most critical elements of the network in terms of their connectivity contribution to the entire system.

Updated definition of level VI lymph node classification in the neck

Acta Oto-Laryngologica, 2007
This update will enable us to precisely address the involvement pattern of level VI and to standardize treatment procedures in order to refine their indications and eventually improve their results and avoid treatment morbidity.The neck level classification is being used worldwide to describe the lymph nodes status of the neck. It provides standardized

The Violated Neck: Cervical Node Biopsy Prior to Definitive Treatment

Otolaryngology–Head and Neck Surgery, 1986
The intent of this study was to determine whether open neck biopsy for patients with squamous cell carcinoma metastatic to the neck influenced the biologic course of the disease or the response to treatment. One hundred ninety‐two patients, treated over a 10‐year period at M.D.

Anatomic definition of a vulnerable extranodal site in AV node reentry

The Annals of Thoracic Surgery, 1994
The success of methods that ablate atrioventricular (AV) node reentry demonstrates that extranodal tissue is part of the reentry circuit. The hypothesis of this study is that atrial tissue approaching the posterior AV node is part of the AV node reentry circuit and is especially suitable for complete division with sparing of AV conduction.

The definition of the sentinel lymph node in melanoma based on radioactive counts

Annals of Surgical Oncology, 2002
There is no consensus on the definition of a hot, nonblue sentinel lymph node (SLN), despite the widespread use of radiocolloid in SLN mapping.A retrospective review of 592 patients with malignant melanoma who underwent SLN mapping was performed. Ex vivo SLN counts and nodal bed counts were obtained by using a gamma probe.

Comparison and definition of spleen and lymph node: A phylogenetic analysis

Journal of Theoretical Biology, 1985
The hitherto largely unsolved problem with a biological definition of spleen versus lymph node seems possible to solve from a phylogenetic point of view. Thus, it is suggested that the spleen be defined as a hemopoietic organ which is able to filter blood with sinusoids. In contradistinction, a lymph node is defined as a hemopoietic organ which is able

Meshless nodes definition analysis for electromagnetic numerical computation

2017 IEEE 5th International Symposium on Electromagnetic Compatibility (EMC-Beijing), 2017
In this paper, the nodal placement of radial point interpolation meshless technique for finite difference time domain method is investigated. The first widely applied placement is a manner similar to the point-matched time-domain finite-element method, which is convenient for the regular node distribution. Another one is the Voronoi decomposition which

Significance of Node Biopsy Before Definitive Treatment of Cervical Metastatic Carcinoma

The Laryngoscope, 1978
A survey was made of 714 radical neck dissections done alone or in combination with resection of a primary malignancy. Sixty‐four (8.9%) of the patients had had a cervical node biopsy before diagnosis and definitive treatment. The complications of wound necrosis, local cervical recurrence, and distant metastasis were significantly higher in those ...
