Lymph node metastasis is the spread of cancer cells into a lymph node.. Lymph node metastasis is different from malignant lymphoma.Lymphoma is a cancer of lymph node, rather than cancer in the lymph node, because lymphoma originates from the lymph node itself, instead of originating elsewhere (e.g., the breast or colon) and spreading to the lymph nodes.
Lymphovascular invasion, especially in carcinomas, usually precedes spread to the lymph nodes that drain the tissue in which the tumour arose. Conversely, cancers with lymph node spread (known as a lymph node metastases), usually have lymphovascular invasion. Lymph node metastases usually precede secondary tumours, i.e. distant metastases.
Lymph node enlargement may be localized to an area, which might suggest a local source of infection or a tumour in that area that has spread to the lymph node. [29] It may also be generalized, which might suggest infection, connective tissue or autoimmune disease, or a malignancy of blood cells such as a lymphoma or leukemia . [ 29 ]
Metastasis is a pathogenic agent's spreading from an initial or primary site to a different or secondary site within the host's body; [1] the term is typically used when referring to metastasis by a cancerous tumor. [2] The newly pathological sites, then, are metastases (mets).
N: degree of spread to regional lymph nodes. Nx: lymph nodes cannot be assessed; N0: no regional lymph nodes metastasis; N1: regional lymph node metastasis present; at some sites, tumor spread to closest or small number of regional lymph nodes; N2: tumor spread to an extent between N1 and N3 (N2 is not used at all sites)
The concept of the sentinel lymph node is important because of the advent of the sentinel lymph node biopsy technique, also known as a sentinel node procedure.This technique is used in the staging of certain types of cancer to see if they have spread to any lymph nodes, since lymph node metastasis is one of the most important prognostic signs.
When there is lymphadenopathy, a biopsy from a lymph node is generally undertaken surgically. In general, a bone marrow biopsy is part of the "work up" for the analysis of these diseases. All specimens are examined microscopically to determine the nature of the malignancy.
However, inguinal lymph nodes of up to 15 mm and cervical lymph nodes of up to 20 mm are generally normal in children up to age 8–12. [ 38 ] Lymphadenopathy of more than 1.5–2 cm increases the risk of cancer or granulomatous disease as the cause rather than only inflammation or infection .
