When is a SLNB required?

When is a SLNB required?

SLNB should be recommended to patients with a clinically negative nodal basin and intermediate thickness primary melanomas (T2 or T3; >1 mm to 4 mm). SLNB should be considered for thick melanomas (T4; >4 mm) and clinically negative nodes. SLNB may be considered for melanoma that exhibits regression (controversial).

How deep is a wide local excision for melanoma?

Surgery (wide local excision) The recommended margin is usually between 5 mm and 10 mm, depending on the type, thickness and site of the melanoma. For thicker tumours, a wider margin of up to 20 mm may be advised.

When is a lymph node biopsy necessary for melanoma?

Sentinel lymph node biopsy should be considered for all patients with melanoma greater than 1 mm in thickness and for patients with melanoma greater than 0.75 mm with other high risk pathological features to provide optimal staging and prognostic information and to maximise management options for patients who are node …

How do you use SLNB?

To do so, a surgeon injects a radioactive substance, a blue dye, or both near the tumor. The surgeon then uses a device to detect lymph nodes that contain the radioactive substance or looks for lymph nodes that are stained with the blue dye.

How long does it take melanoma to spread to lymph nodes?

How fast does melanoma spread and grow to local lymph nodes and other organs? “Melanoma can grow extremely quickly and can become life-threatening in as little as six weeks,” noted Dr. Duncanson.

What is the survival rate for melanoma in the lymph nodes?

If a sentinel node biopsy yields findings of melanoma in the lymph nodes, the 5-year survival is approximately 65%. Stage IIB: The 5-year relative survival rate is approximately 72-75%. If a sentinel node biopsy yields findings of melanoma in the lymph nodes, the 5-year survival is 50-60%.
