Observational Study to Assess Adherence Oral Anticancer Therapies

Oral anticancer treatments are increasingly numerous. They represent an additional alternative in the therapeutic arsenal of the clinician, and appear to satisfy patients who prefer this route of administration over intravenous treatment. The objective of oral therapies is twofold: to remove the constraints and risks associated with infusions and to allow the patient to follow his treatment at home. However, they have significant adverse effects that may affect patients, who are sometimes at a disadvantage compared to how they are treated, and potentially lead to non-compliance with the consequences. This study will identify the factors associated with non-adherence and determine the impact of this non-adherence in terms of treatment efficacy and tolerance. The aim of this routine care study is to evaluate the adherence to oral anticancer therapies during 3 months.
