Disparities in Thoracic Oncology Patients

Area of Science:

• Oncology
• Public Health
• Health Disparities

Background:

• Lung cancer remains a leading cause of global mortality.
• Significant disparities exist in lung cancer outcomes across different populations.
• Advances in lung cancer care have not been equitably distributed.

Purpose of the Study:

• To examine lung cancer disparities in epidemiology, risk factors, screening, diagnosis, treatment, and survival.
• To identify the primary causes of these lung cancer discrepancies.
• To synthesize evidence on lung cancer disparities by race, ethnicity, socioeconomic status, sex, geography, and healthcare access.

Main Methods:

• Conducted a narrative review of peer-reviewed literature.
• Analyzed national cancer surveillance reports and large population-based studies.
• Synthesized evidence on disparities in prevention, early detection, treatment, and outcomes.

Main Results:

• Persistent differences observed in lung cancer incidence, stage, treatment, and survival.
• Minority groups, low-income, uninsured, and rural populations face a higher burden and worse outcomes.
• Unequal access to low-dose computed tomography (LDCT) screening, diagnostics, treatments, and clinical trials was noted.

Conclusions:

• Lung cancer disparities are primarily driven by structural, social, and healthcare system factors, not biological differences.
• Equitable screening, prompt high-quality treatment, and inclusive research are essential.
• Policy-driven, culturally sensitive actions are needed to improve lung cancer outcomes for all populations.
