A meta-analysis of nevus-associated melanoma: Prevalence and practical implications

The reported prevalence of nevus-associated melanoma varies substantially. We performed a systematic review and meta-analysis to determine the incidence and prevalence of this disease; we also performed subanalyses considering age, tumor thickness, and nevus-type classification. In 38 observational cohort and case–control studies, 29.1% of melanomas likely arose from a preexisting nevus and 70.9% de novo. Any given melanoma was 64% less likely to be nevus-associated than de novo (risk ratio 0.36, 95% confidence interval [CI] 0.29-0.44; P < .001; I2 = 99%); nevus-associated melanomas had a lower mean Breslow thickness than de novo melanomas (mean difference –0.39 mm; 95% CI –0.60 to –0.18; P = .0003; I2 = 66%).
