What is the Definition of Cure in Non-small Cell Lung Cancer?

The concept of cure from cancer is important to patients, but can be difficult to communicate in terms that are meaningful. This is because there are a number of definitions of cure that are applied by clinicians, patients and the public, and by policymakers that have a different meaning and significance. In this article, we provide a narrative review of the evidence concerning cure in lung cancer and show how the different definitions may apply in different settings. A better understanding of the various concepts of cure will improve communication with patients on this important topic. This article is based on previously conducted studies and does not contain any new studies with human participants or animals performed by any of the authors.
