Feigelson HS, et al. - Through this population-based retrospective cohort study of 1,931 cases of invasive melanoma in the United States, the researchers investigated melanoma incidence, recurrence, and mortality among members of Kaiser Permanente Colorado (KPCO) between January 1, 2000, and December 31, 2015. This is the first population-based study in the United States to assess patient features linked to recurrence risk. Stage, male gender, older age at diagnosis, lower socioeconomic status, and comorbidity index were factors linked with all-cause mortality. Results were the same, with the exception of age, for melanoma-specific mortality. Hence, data from an insured patient population, such as KPCO, have the tendency to improve our understanding of emerging trends in melanoma. Also, an increased risk of both recurrence and death was observed in men vs women, and they could profit from a more intensive follow-up.
