Disparities in melanoma-specific mortality by race/ethnicity, socioeconomic status, and health care systems.

BACKGROUND: Despite encouraging trends in survival, sociodemographic inequalities persist among patients with melanoma. OBJECTIVE: We sought to quantify the effect of race/ethnicity, socioeconomic status, and health care systems on melanoma-specific mortality within an insured population of patients. METHODS: Using a retrospective cohort study, we identified insured adults diagnosed with Stage I to IV melanoma from January 1, 2009, to December 31, 2014, followed through 2017, from the California Cancer Registry. We compared melanoma-specific mortality between insured patients diagnosed within the largest vertically integrated health care system in California, Kaiser Permanente Southern California, and insured patients with other private insurance (OPI). RESULTS: Our cohort included 14,614 adults diagnosed with melanoma. Multivariable analyses demonstrated that race/ethnicity was not associated with survival disparities, while socioeconomic status was a strong predictor of melanoma-specific mortality, particularly for those with OPI. For example, hazard ratios demonstrate that the poorest patients with OPI have a 70% increased risk of dying from their melanoma compared to their wealthiest counterparts, while the poorest patients in Kaiser Permanente Southern California have no increased risk. LIMITATIONS: Our main limitation includes inadequate data for certain racial/ethnic groups, such as Native Americans. CONCLUSIONS: Our findings underscore the persistence of socioeconomic disparities within an insured population, specifically among those in non-integrated health care systems.

Management of acute radiation dermatitis: A review of the literature and proposal for treatment algorithm.

Radiation dermatitis is a common sequela of radiation therapy; up to 95% of patients will develop moderate-to-severe skin reactions. No criterion standard currently exists for the treatment of acute radiation-induced skin toxicity. It is therefore imperative to develop a greater understanding of management options available to allow clinicians to make informed decisions when managing radiation oncology patients. This literature review discusses the topical agents that have been studied for the treatment of acute radiation dermatitis, reviews their mechanisms of action, and presents a treatment algorithm for clinicians managing patients experiencing radiation dermatitis.
