Impact of socioeconomic and sociodemographic factors on melanoma–analysis of survival outcomes
摘要
Melanoma incidence is rising, underscoring the importance of early detection to enhance patient survival status. However, notable disparities influenced by socioeconomic status (SES) and race continue to affect diagnosis timing and treatment outcomes. This study analyzed data from 55,644 melanoma cases from the Surveillance, Epidemiology, and End Results (SEER) database spanning 2004 to 2020. Statistical methods included Kaplan-Meier survival analyses, t-tests, Chi-Squared tests, and ANOVA, with significance defined at p < 0.05. Results showed significant associations between SES and age at melanoma diagnosis, as well as survival outcomes. Hispanic Whites and Asian/Pacific Islanders were generally diagnosed at younger ages compared to Non-Hispanic Whites, while no significant age differences were observed among Black and American Indian/Alaskan Native populations. Higher income was strongly linked to earlier diagnosis and improved survival, particularly among females earning over $50,000 annually. Patients who underwent lymph node evaluations demonstrated better survival outcomes, although these associations may reflect underlying differences in disease characteristics or access to care rather than a direct effect of the procedure. Biopsy rates did not vary significantly across income groups; however, White patients were notably more likely to receive indicated lymph node biopsies than patients from other racial groups. Study limitations included smaller subgroup sizes, restricting detailed analyses of income ranges outside the $35,000-$75,000 bracket. Additionally, the use of combined staging categories might obscure nuanced disease progression distinctions. In conclusion, lymph node evaluations were associated with improved survival in several groups, though causality cannot be determined from these data. A range of factors related to access, diagnosis timing, and treatment pathways may contribute to observed disparities. Yet, disparities in lymph node biopsy performance linked to socioeconomic and racial factors persist. Addressing these disparities through targeted educational programs and policy initiatives aimed at healthcare providers and patients of lower SES is critical. Increasing awareness and promoting equitable healthcare practices can substantially reduce these disparities and improve melanoma outcomes across diverse patient populations.
