Comparison Between the Assessment of Anxious and Depressive Symptomology

In palliative care, anxiety and depression in advanced cancer are under evaluated, under diagnosed and therefore under treated. 5 to 30% of patients present anxious and depressive disorders. Physical symptoms are easy to assess. But in palliative care it is important to take care of moral suffering. However, evaluation and management of patient's anxiety and depressive symptoms are difficult for physicians and caregivers. The investigators would like to specifically compare the patient's evaluation of anxious and depressive symptomatology in palliative care with the evaluation by the physician, the nurse and the caregiver. Then the investigators will try to collect the caregivers's difficulties in the management of anxious and depressive symptoms.
