A T1a melanoma generally is not considered appropriate for staging of the regional lymph nodes with sentinel lymph node biopsy (with exceptions noted in the guideline), whereas a T1b melanoma may be considered for SLNB staging --though rates of SLN positivity remain relatively low in the T1b group."
Malignant melanoma often metastasizes through lymphatic channels to the skin or subcutaneous tissues, as well as to regional lymph nodes. Skin and subcutaneous lesions that occur within 2 cm of the primary tumor are known as satellite lesions, while those that occur beyond 2 cm are considered in-transit metastases.
Hypothesis of sentinel node(SLN) biopsy is that, if these nodes are negative for malignancy, the remaining regional lymph nodes will also be negative.
Gastric and esophageal cancer commonly metastasizes to liver, regional lymph nodes, lung and bone2.
