Long-COVID and long-term cancer survivorship-Shared lessons and opportunities.

As of 2022, close to 90 million persons in the United States, 243 million persons in Europe and 585 million worldwide have been infected with the novel SARS-CoV-2 (COVID-19) virus and survived. Estimates vary but suggest that up to 50% may experience long-term sequelae, termed 'Long-COVID'. While Long-COVID is a new condition, the phenomenon of disabling long-term effects following an illness requiring ongoing surveillance and management is not. In this commentary, we discuss how Long-COVID parallels the experiences of long-term cancer survivors, highlight shared challenges and offer opportunities to improve research and clinical care for both growing populations of patients as well as other long-term chronic, disabling conditions.
