Investigating Differences in Melanoma Mortality Based on Demographic Information from 1999-2022 Using CDC Wonder
Source: AVAHO, September 2024
Background
Melanoma is a malignant type of skin cancer and is the fifth most common type of cancer in the United States. The purpose of this study is to determine how demographic information such as race and gender may influence mortality rates in melanoma patients. To date, no previous studies have analyzed epidemiological trends in melanoma mortality using the CDC Wonder database. However, previous literature has suggested that non-Hispanic Whites have the highest mortality rate.
Methods
CDC Wonder is a database that contains mortality and demographic information for various pathologies. Melanoma cases were specified using the ICD-10 code C43. Patients over the age of 35 were considered for this study. Mortality rates were generated based on gender, race, and a combination of both variables. Data analysis involved finding the rates and 95% confidence intervals for the crude and age-adjusted mortality rate (AAMR) per 100,000. Joinpoint regression analysis was also used.
Results
Several differences in the age-adjusted mortality rate were observed. In every year from 1999 to 2022, the non-Hispanic White group (NH White) had the highest mortality rate, whereas all other races had similar rates. Meanwhile, when stratifying by both race and gender, it appears that NH White males have the highest rate in mortality. In 2022, the mortality rate for NH White males was 8.8 per 100,000, whereas the second highest rate belonged to the NH White female group (4 per 100,000). All other racial and gender combinations had similar mortality rates. The trends in mortality rates did not fluctuate much from the years 1999-2022. No significant deviation in mortality trends were seen after the start of the COVID-19 pandemic.
