Racial Disparities in Nasopharyngeal Carcinoma Characteristics and Survival

Area of Science:

• Oncology
• Epidemiology
• Genetics

Background:

• Nasopharyngeal carcinoma (NPC) exhibits significant global and ethnic variations.
• Understanding disparities in NPC presentation and outcomes across racial groups is crucial for targeted interventions.

Purpose of the Study:

• To compare histological subtypes, disease stage, and survival rates of nasopharyngeal carcinoma (NPC) among Chinese American, Non-Hispanic White, and African American patients.
• To identify racial disparities in NPC diagnosis and prognosis.

Main Methods:

• Retrospective analysis of 1646 NPC patients diagnosed between 2010-2017.
• Statistical methods included chi-square tests, propensity score matching, Kaplan-Meier analysis, and Cox proportional hazards models.

Main Results:

• Chinese Americans had a higher prevalence of undifferentiated non-keratinizing squamous cell carcinoma.
• African American patients presented with more advanced stage III-IV disease.
• Non-Hispanic White and African American patients experienced significantly worse overall survival compared to Chinese American patients.

Conclusions:

• Racial background is a significant determinant of histological subtype, stage at diagnosis, and overall survival in nasopharyngeal carcinoma (NPC).
• These findings highlight the need for race-specific approaches in NPC management and research.
