Racial-Ethnic, Education, and Socioeconomic Differences in the Treatment of Head and Neck Melanoma in situ: A Surveillance Epidemiology and End Results Population-Based Analysis.

BACKGROUND

Incidence and treatment disparities for cutaneous melanomas have been documented among racial and sociodemographic minorities. However, the association between treatment types, race, and socioeconomic status remains unknown.

OBJECTIVE

To characterize treatment differences for head and neck melanoma in situ (MIS) and lentigo maligna (LM) based on race and sociodemographic variables.

MATERIALS AND

METHODS

A population-based retrospective cohort study of the Surveillance Epidemiology and End Results database (1998-2016) was performed. Univariate and multivariate logistic regression modeling evaluated the association of race and US census-reported sociodemographic factors with Mohs micrographic surgery (MMS) utilization.

RESULTS

A total of 76,328 adult patients with head and neck MIS/LM were included. MMS accounted for 11.8% of total cases, with increased utilization observed since 1998-2002. Compared with areas with greater percentages of individuals completing high school (first quartile), patients living in the second (Odds ratio [OR] 0.71; 95% confidence interval [CI] 0.64-0.80; p < .001), third (OR 0.74; 95% CI 0.63-0.86; p < .001), and fourth quartiles (OR 0.44; 95% CI 0.35-0.55; p < .001) were less likely to undergo MMS for their MIS/LM.

CONCLUSION

Educational efforts and awareness can bridge the knowledge gaps of appropriate treatment in patients with head and neck MIS/LM.
