Disparities in lung cancer.

Lung cancer is the second most common cancer and the leading cause of cancer death among men and women in the United States. Despite a substantial decline in lung cancer incidence and mortality across all races in the last few decades, medically underserved racial and ethnic minority populations continue to carry the greatest burden of disease throughout the lung cancer continuum. Black individuals experience a higher incidence of lung cancer due to lower rates of low-dose computed tomography screening, which translate into advanced disease stage at diagnosis and poorer survival outcomes compared with White individuals. With respect to treatment, Black patients are less likely to receive gold standard surgery, have access to biomarker testing or high-quality treatment compared with White patients. The reasons for those disparities are multifactorial and include socioeconomic (eg, poverty, lack of health insurance, and inadequate education), and geographic inequalities. The objective of this article is to review the sources of racial and ethnic disparities in lung cancer, and to propose recommendations to help address them.

Cancer healthcare disparities among African Americans in the United States.

A need exists to examine racial disparities in the healthcare arena and the impact on patients with cancer. Despite ongoing efforts to increase equity in primary healthcare access, racial and socioeconomic disparities persist, thus contributing to disproportionate treatment outcomes and survivorship among minority and low-income patients. Such disparities have been revealed in treatment cohorts of patients with multiple forms of cancer, including breast, cervical, ovarian, endometrial, prostate, lung, colorectal, gastrointestinal, and hepatocellular, and have been attributed to a range of co-occurring behavioral, social determinants of health, underlying genetic factors, as well as access to educational opportunities that limit the quality of informed healthcare. These various interrelated factors widen cancer healthcare disparities synergistically throughout underserved communities, and their influence has been amplified by the coronavirus disease 2019 (COVID-19) pandemic. Fundamentally, a lack of basic and clinical research exists that fails to adequately reflect diversity and minority involvement in drug development. Although overcoming the obstacles responsible for chronic treatment disparities is a formidable task, promising means of achieving more uniform quality healthcare are becoming more clearly elucidated. To reduce disease progression, increase overall survival, and improve the health of vulnerable populations, it is necessary to identify and fully disclose environmental, biological, and ancestral factors that impact the risk for cancer; heal historical fractures within communities; and increase participation of racial and ethnic minorities in screening efforts and research studies. This requires developing a system of justice and trust based on specific, solution-oriented grassroots community efforts working in tandem with medical and pharmaceutical leaders. By fully exploring and pinpointing the underlying causes of healthcare disparities, it should be possible to define strategies and interventions most likely to transform cancer care. The ultimate goal is understanding individual, cultural, and biological vulnerabilities, including environmental and epigenetic liabilities, to optimize cancer prevention, diagnosis, and treatment.

Colorectal Cancer: In the Pursuit of Health Equity.

Colorectal cancer mortality has decreased considerably following the adoption of national screening programs, yet, within at-risk subgroups, there continue to be measurable differences in clinical outcomes from variations in screening, receipt of chemotherapy, radiation or surgery, access to clinical trials, research participation, and survivorship. These disparities are well-described and some have worsened over time. Disparities identified have included race and ethnicity, age (specifically young adults), socioeconomic status, insurance access, geography, and environmental exposures. In the context of the COVID-19 pandemic, colorectal cancer care has necessarily shifted dramatically, with broad, immediate uptake of telemedicine, transition to oral medications when feasible, and considerations for sequence of treatment. However, it has additionally marginalized patients with colorectal cancer with historically disparate cancer-specific outcomes; among them, uninsured, low-income, immigrant, and ethnic-minority patients-all of whom are more likely to become infected, be hospitalized, and die of either COVID-19 or colorectal cancer. Herein, we outline measurable disparities, review implemented solutions, and define strategies toward ensuring that all have a fair and just opportunity to be as healthy as possible.
