Tragic Triad of Tobacco Dependence, Cancer, and COVID-19 Pandemic: An Urgent Call for Attention by Health Care Systems and Professionals.

Tobacco smoke is a well-known carcinogen associated with multiple malignancies. Patients with cancer, as well as survivors, who continue to smoke are at a greater risk for poor cancer treatment outcomes. With the emergence of the COVID-19 pandemic, there is increased frequency and severity of the infection in patients with cancer. Furthermore, smoking and/or vaping increases incidence or likelihood of progression of COVID-19. Cigarette smoking, cancer, and COVID-19 each impose disproportionate burden of illness and death among racial and ethnic minorities. Geographic and population-specific analyses reveal that neighborhoods with lower income and higher minority populations have more tobacco/vape shops and face increased risk associated with tobacco marketing. Referral to tobacco cessation has been reduced during the pandemic. To reduce the adverse health effects of tobacco dependence among patients with cancer during the pandemic, urgent evidence-based solutions are described for health systems and professionals to prioritize tobacco cessation for patients with cancer in the midst of the COVID-19 pandemic, on the basis of cessation implementation at City of Hope Medical Center.
