2. Melanoma - Wikipedia

   en.wikipedia.org/wiki/Melanoma

   Although controversial, sentinel lymph node biopsies and examination of the lymph nodes are also performed in patients to assess spread to the lymph nodes. A diagnosis of melanoma is supported by the presence of the S-100 protein marker. HMB-45 is a monoclonal antibody that reacts against an antigen present in melanocytic tumors such as ...

3. Sentinel lymph node - Wikipedia

   en.wikipedia.org/wiki/Sentinel_lymph_node

   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.

4. Breslow's depth - Wikipedia

   en.wikipedia.org/wiki/Breslow's_depth

   A large study validated the importance of tumor depth (but not Breslow's original description) as one of the three most important prognostic factors in melanoma (the others being T stage and ulceration). [4] Breslow's depth also accurately predicted the risk for lymph node metastasis, with deeper tumors being more likely to involve the nodes. [5]

5. TNM staging system - Wikipedia

   en.wikipedia.org/wiki/TNM_staging_system

   The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the anatomical extent of the spread of malignant tumours (cancer). It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia or tumors of the central nervous system. Most common tumors have their ...

6. Acral lentiginous melanoma - Wikipedia

   en.wikipedia.org/wiki/Acral_lentiginous_melanoma

   In the event that the melanoma spreads to other sites such as the lymph nodes, another biopsy called the Sentinel lymph node biopsy may provide more information in terms of outcomes. [21] More extensive melanomas may require wider excision (margins of 0.5 cm or more), digital amputation, lymphangiogram with lymph node dissection, or ...

7. Metastasis - Wikipedia

   en.wikipedia.org/wiki/Metastasis

   "Positive nodes" is a term that would be used by medical specialists to describe regional lymph nodes that tested positive for malignancy. It is common medical practice to test by biopsy at least one lymph node near a tumor site when carrying out surgery to examine or remove a tumor. This lymph node is then called a sentinel lymph node.
