To determine whether a lymph node is benign or malignant, it's important to first understand what kind of ultrasound description indicates a malignant lymph node: The lymph node is spherical, for example, 3×3 cm (30×30 mm) in size, with unclear boundaries, disordered internal structure, di...
Enlargement of a lymph node of the neck may appear as a manifestation of a variety of diseases, such as specific or nonspecific inflammation of head and neck organs, metastases, and hemoblastoses. The principle ultrasound signs of lymph node differentiation are the size, shape, structure, and ...
One thousand three hundred and thirty-two paired clinical and nonblinded sonographic tests of the locoregional lymph node areas were performed. Lesions suspicious of metastases were examined histopathologically. Of note, sensitivity [0.9394 (95% confidence interval: 0.7977-0.9926)] and specificity [...
Sentinel lymph node (SLN) biopsy has become the standard of care in axillary staging of breast cancer patients who are clinically node negative as it reduc... NK Saidha,R Aggarwal,A Sen - 《Indian Journal of Surgical Oncology》 被引量: 5发表: 2017年 Comparison of microvascular flow imaging...
Influence of Frozen-Section Analysis of Sentinel Lymph Node and Lumpectomy Margin Status on Reoperation Rates in Patients Undergoing Breast-Conservation Th... Background Frozen-section analysis (FS) of the sentinel lymph node (SLN) is performed to avoid reoperation for axillary lymph node dissection...
This study was conducted to see whether the size (measured by maximal short axis diameter), shape (expressed in terms of ratio dividing long axis diameter of the node by short axis diameter or L/S ratio), marginal clarity (regular or irregular margin), internal echo-pattern (homogeneous hypoe...
Therefore we prospectively investigated the number and size of lymph nodes (LN) expressed as the total lymph node volume (tLNV) within the hepatoduodenal ligament (HDL) in 48 consecutive patients with PBC and in 43 healthy controls (hc).Methods: In the present study the LN in the liver ...
The shortest diameter, the short/long diameter ratio (S/L ratio), margins and internal echo structure of the lymph node were evaluated by US. The internal echo structure was divided into six patterns: homogeneous hypoechoic, homogeneous hyperechoic, heterogeneous, eccentric hyperechoic, centric ...
Sentinel lymph nodes (SLNs) are the first station of lymph nodes that extend from the breast tumor to the axillary lymphatic drainage. The pathological status of these LNs can predict that of the entire axillary lymph node. Therefore, the accurate identification of SLNs is necessary for sentinel...
Abstract 186: RHOA, RAC1 and PAK1 evaluation in paired stromal fibroblasts of breast cancer primary and of lymph node metastasis: Importance of these biomarkers in lymph node invasion The importance of tumor-stromal cells interactions in breast tumor progression and invasion has been recognized; ther...
