Lymphadenectomy, or lymph node dissection, is the surgical removal of one or more groups of lymph nodes. [1] It is almost always performed as part of the surgical management of cancer . In a regional lymph node dissection , some of the lymph nodes in the tumor area are removed; in a radical lymph node dissection , most or all of the lymph nodes ...
The neck dissection is a surgical procedure for control of neck lymph node metastasis from squamous cell carcinoma (SCC) of the head and neck. [1] The aim of the procedure is to remove lymph nodes from one side of the neck into which cancer cells may have migrated.
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.
Head and neck cancers are staged according to the TNM classification system, where T is the size and configuration of the tumor, N is the presence or absence of lymph node metastases, and M is the presence or absence of distant metastases. The T, N, and M characteristics are combined to produce a "stage" of the cancer, from I to IVB.
Lymph nodes may become enlarged in malignant disease. This cervical lymphadenopathy may be reactive or metastatic. [1] Alternatively, enlarged lymph nodes may represent a primary malignancy of the lymphatic system itself, such as lymphoma (both Hodgkin's and non-Hodgkin's), [6] lymphocytic leukemia, [1] Lymphadenopathy that lasts less than two weeks or more than one year with no progressive ...
During the surgery they will also do a sentinel lymphoid biopsy. Because with a PET scan they can’t see if it’s spread to lymph nodes.” ... cancer cells and comes with side effects such as ...
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.
Involvement of the cervical lymph nodes with metastatic cancer is the single most important prognostic factor in head and neck squamous cell carcinoma and may be associated with a halving of survival. Where the cancer has penetrated the capsule of the lymph gland (extracapsular extension) survival may be decreased by a further 50%.
