Cancer has become a chronic disease, often requiring long-term, chronic oncological drug treatment. As a result, the oncological treatment is exposed to a large number of patients who may be on concurrent treatments for other health conditions and/or who may suffer from concomitant illnesses, both of which may affect the efficacy and safety of the oncological treatment by contributing to the increased incidence of adverse events and/or loss of efficacy.
