Thickness-Specific Incidence of Cutaneous Melanoma in the United States

Source: The ASCO Post, April 2022

In a population-based cohort study reported in JAMA Oncology, Chen et al found that the incidence of overall cutaneous melanoma and thinner tumors was stable in the United States from 2010 to 2018, with an increased incidence of the thickest (T4) melanomas being observed. Lower socioeconomic status and race/ethnicity were associated with an increased risk of diagnosis of the thickest melanomas.

Study Details
The study involved data on 187,487 patients with a new diagnosis of invasive cutaneous melanoma from the Surveillance, Epidemiology, and End Results Registry from January 2010 to December 2018. Age-adjusted incidence rates of melanoma were calculated by tumor thickness (Breslow thickness) and annual percentage change in incidence rates. The associations of tumor thickness with socioeconomic status were evaluated in 134,359 patients diagnosed with melanoma from 2010 to 2016.
