أهمية: Most patients who present with primary cutaneous melanomas have thin tumors (≤1.0 mm in Breslow thickness, ie, pT1a and pT1b). Although their prognosis is generally considered to be excellent, there is limited precise information on the association of risk of death with specific Breslow measurements in thin lesions.
الهدف: To assess the relative effect of a 0.8-mm Breslow thickness threshold with respect to the incidence of both melanoma-related and nonmelanoma-related death.
التصميم والإعداد والمشاركين: Registry data for all Australians diagnosed with thin invasive primary melanomas between 1982 and 2014 were analyzed. Data were extracted from all 8 Australian state and territory population-based cancer registries. Dates and causes of death were obtained from the Australian National Death Index. Adults diagnosed with a first invasive primary melanoma of 1.0 mm or smaller in thickness were included.
مكشف: First invasive primary melanoma between 1982 and 2014.
