The average 5-year survival rate for patients diagnosed with cancer in France is estimated at 53%. Nearly half of all patients diagnosed with cancer are not alive 5 years after diagnosis Discontinuation of anti-tumor treatments is therefore a major issue in their care. Discussing the discontinuation of specific treatments requires scientific oncological skills but also communication skills. The difficulties encountered by oncologists concerning communication about the end of life are linked to the doctors' personal discomfort with death, their fear of the responsibility of stopping chemotherapy, and their distrust of their colleagues. On the other hand, they may also come from patients who are supposedly reluctant to talk about the end of life, a reluctance that is heightened in the case of language barriers, young age or pressure from families. Finally, the place of practice could explain some of the difficulties in talking about the end of life, notably because of a lack of training in delivering bad news or a stigma attached to palliative care.

This exploratory work should make it possible to describe the characteristics of the announcement of the cessation of anti-tumor treatments in ambulatory patients, to evaluate distress, anxiety, depressive symptomatology, as well as the satisfaction of the patients concerning the management received.

In this pilot study, we will describe for the first time the discontinuation of anti-tumour treatments in outpatients with advanced cancer and evaluate the psychological impact on patients following this announcement.

In outpatients patients, these announcements of treatment cessation will be made in a conventional oncology consultation or in Palliative Care Day Hospital.

This exploratory work should make it possible to describe the characteristics of the announcement of the cessation of anti-tumour treatments in ambulatory patients, to assess distress, anxiety, and the depressive symptomatology, as well as patient satisfaction with the treatment received.

The 2 hypotheses of this research work are the following:

1. the announcement of the cessation of specific treatments can generate distress, anxiety and depressive symptoms for the patient, and may be a source of dissatisfaction with the quality of care received.
2. the existence of an improvement in the quality of the announcement when it is made in HDJ SP in comparison with an announcement made in a conventional oncology consultation; reduction of the psychological impact for the patient, reduction in markers of aggressiveness of care at the end of end of life care. The doctors involved in this project have received training in listening to and supporting patients with advanced cancer in a palliative situation.
