Further imaging findings regarded as suggestive for malignant lymph node disease were a spherical lymph node shape [ 14], nodal necrosis [ 15] and irregular lymph node borders [ 16].
The abovementioned reshaping of mediastinal lymph-node borders will result in an increase in so-called 'minimal N2', limited to a single station.
Lymph node dissection along the upper border of the pancreas is essential for radical gastric cancer surgery.
The literature shows that the diagnostic accuracy of MRI is 67 95%, its sensitivity is 37 90%, and its specificity is 71 100%[211, 32, 46, 47, 48, 49, 50, 51, 52, 53, 54], even when other signs of metastatic disease, such as loss of normal lymph node architecture, rounder form, irregular borders and heterogeneous signal intensity, are considered.
The distal end of the caudal mediastinal lymph node was ligated and the borders of the diaphragm and posterior right hemithorax were cauterised to eliminate contamination of the caudal mediastinal lymph node by systemic afferent lymphatics.
Thus, the topic of peripheral T cell activation and differentiation is well-trodden ground at this point, but discussions of these events often stop at the border of the lymph node, where priming occurs.
Loss of membranous CD166 was linked to more advanced T classification (P=0.002), lymph node metastasis (P=0.004), an infiltrating tumour border configuration (P<0.001), and worse overall survival compared with patients with CD166 overexpression (P=0.015; Figure 2A).
However, proven metastatic lymph nodes with unsharp borders indicate extracapsular spread (Fig. 3), suggesting poor patient prognosis.
The superior field border extended ∼5 cm cranial to the tumour, and the inferior border extended caudally to include the coeliac lymph node (LN) region.
Forty-four senodesl nodes were collected from the axilla, 76 sentinel nodes from cervical lymph node basins and one sentinel node from the lateral border of the left scapula (Figs. 1, 2).
