thin melanoma

thin melanoma

Stage I cutaneous melanoma A melanoma measuring < 1 cm in diameter, characterized by virtually 100% survival; the prognosis is less favorable if the lesion is > 0.73 mm in thickness–73% 5-yr survival or > 1.5 mm–63% 5-yr survival. See Melanoma.

The finding that patients with histologic regression have half the risk for micrometastases in sentinel lymph node biopsy, compared with patients without regression gives a clear answer to the question of whether patients with thin melanoma and regression should undergo SLNB, and that answer is "No."

At present, the decision regarding whether to recommend SLNB in a patient with a thin melanoma is based upon a general gestalt, said Dr.
Even though patients with early-stage disease (thin melanoma, Breslow depth <1.0 mm) are thought to have an excellent clinical outcome (>85% survival during a 10-year period) (6) and can be treated effectively, 15% of melanoma deaths result from metastases of thin lesions.
However, in thin melanomas, thickness does not necessarily discriminate between radial and vertical growth phase.
Finally, David Elder, MB, ChB, FRCPA, reviews the literature and work from his laboratory on prognostic modeling in thin melanoma, which is defined as melanoma invasive to less than 1 mm according to Breslow.
