Short pharmaceutical interviews from D15 to M12 will be replaced by long pharmaceutical consultations of 30 to 60 minutes. The latter consisting in a full clinical medication review and incorporating the pedagogic aspects addressed in the short pharmaceutical interviews but for all therapeutic drugs taken by the patient. Additional consultations are possible on the request of the oncologist and/or patient. The consultations carried out at the request of the oncologist and/or the patient will be counted.
