Acta Dermato-Venereologica, 95 (8), 940-942.00015555http://hdl.handle.net/11441/62887Age and sex have been identified as predictors of outcome in malignant melanoma (MM). The aim of this multicentre, cross-sectional study was to analyse the role of age and sex as explanatory variables for the diagnosis of thin MM. A total of 2,430 patients with MM were recruited. Cases of in situ (Tis) and T1 MM were more frequent than T2–T4 MM (56.26% vs. 43.74%). Breslow thickness increased throughout decades of life (analysis of variance (ANOVA) p < 0.001), with a weak correlation between Breslow thickness and patient's age (r = 0.202, p < 0.001). Breslow thickness was significantly less in women (1.79 vs. 2.38 mm, p = 0.0001). Binary logistic regression showed a significant (p < 0.001) odds ratio for age 0–29 years (1.18), and 30–59 years (1.16), and for women (1.09). Age and sex explained 3.64% of the variation observed in Tis–T1 frequency (R2 = 0.0364). Age and sex appear to explain a low percentage of the variation in the early detection of MM.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Agemalignant melanomaPrognostic predictorsSexThin Melanomainfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.2340/00015555-2115
