In order to improve the care pathway of patients on anticancer oral therapies, the investigators suggest in this research project to integrate into the medical care a "Clinical Pharmacy follow-up" for the patient at the hospital in the form of "pharmaceutical consultations". These pharmaceutical consultations carried out in coordination with the hospital clinical teams also aim to make the link between the hospital and community pharmacists. These pharmaceutical consultations were initiated in Marseille and Grenoble University Hospitals in order to know the special needs of patients under oral chemotherapies. However, the impact of these pharmaceutical consultations in a population of patients receiving ambulatory oral therapy remains unknown and needs to be evaluated using objective criteria such as the rate of adverse events which the consequences are considerable both for the patient and the society.
