biostudies-literatureUnknown103Ahimbisibwe ALittle is known about if and how nevi and pigmentation are associated with melanoma-specific mortality. However, increased melanoma awareness in people with lighter pigmentation and many nevi may result in earlier diagnosis of thinner less-lethal tumors. The aim of this study was to investigate associations between nevus count (asymmetrical > 5 mm and small symmetrical), pigmentary characteristics (hair colour, eye colour, skin colour, freckling, pigmentary score), and melanoma-specific mortality in subjects with melanomas > 1 mm. Data from the Norwegian Women and Cancer cohort, established in 1991, with complete follow-up of melanoma patients until 2018 through the Cancer Registry of Norway, were used to estimate hazard ratios with 95% confidence intervals for the associations between nevActa dermato-venereologicaadv4403https://www.ebi.ac.uk/biostudies/studies/S-EPMC10108620biostudies-literatureNevus Count, Pigmentary Characteristics, and Melanoma-specific Mortality among Norwegian Women with Melanoma >1.0 mm Thick.PMC10108620Weiderpass ERueegg CSGhiasvand RSandanger TMVeierod MBValberg MGreen ACRimal RRobsahm TEAhimbisibwe AfalseNevus Count, Pigmentary Characteristics, and Melanoma-specific Mortality among Norwegian Women with Melanoma >1.0 mm Thick.Little is known about if and how nevi and pigmentation are associated with melanoma-specific mortality.
