Social and Biological Determinants in Lung Cancer Disparity

Area of Science:

• Oncology
• Public Health
• Health Disparities

Background:

• Lung cancer is a leading global cause of death, with persistent challenges in long-term patient survival.
• Significant racial disparities exist in lung cancer incidence, treatment, and survival, particularly affecting African American (AA) men compared to European American (EA) men.

Purpose of the Study:

• To review and synthesize the multifaceted factors contributing to racial disparities in lung cancer outcomes.
• To highlight the interplay of social, biological, and environmental influences on lung cancer susceptibility and prognosis in African Americans.

Main Methods:

• Literature review focusing on smoking patterns, screening, early detection, tumor biology, immunity, and comorbid conditions.
• Analysis of social determinants of health, including socioeconomic status and systemic racism.

Main Results:

• Differences in smoking patterns, screening, and early detection contribute to disparities.
• Variations in tumor biology, immune responses, and comorbid conditions play a role in poorer outcomes for African Americans.
• Social factors like socioeconomic status and systemic racism are significant contributors to these disparities.

Conclusions:

• The higher susceptibility and poorer outcomes of African Americans with lung cancer result from an intricate combination of social, biological, and environmental factors.
• Addressing these disparities requires a comprehensive approach that considers the unique challenges faced by this population.
