The aim of this study is to demonstrate the efficacy of a proactive intervention to approach death thoughts among people with advanced cancer compared to usual care (the reactive approach) via a feasible approach with previous indicators of efficacy: Go-TAD (Give the Opportunity to Talk about Death). The benefits of the intervention will be evaluated in terms of: reduction of emotional distress and hopelessness and improvement the doctor-patient relationship, as well as improvement of quality of life for the patient. A Phase II randomized controlled mixed methods clinical trial (RCT) will be carried out within 4 Palliative Care units of tertiary care hospitals in Catalonia. Participants will be persons with advanced cancer defined according to the criteria of the American Society of Clinical Oncology. Participants will be randomly assigned to an intervention group or control group. In the intervention group, the participants will receive a medical visit that will include the 4 open-ended questions comprising the Go-TAD intervention, while the control group will receive usual care. Between 24 and 96 hours later, a researcher from outside the center will assess study outcome measures. To strengthen the study conclusions, a qualitative study will be carried out in which the experiences of the participants in the intervention group and of their professionals who administered the Go-TAD will be explored in depth.

The inclusion criteria will be:

1. patients with advanced cancer defined according to ASCO (American Society of Clinical Oncology) criteria referred for the initial palliative care (PC) consultation.
2. age over 18 years
3. ECOG 0-3 (functionality status)
4. outpatients and inpatients
5. patients who can sign the informed consent
6. patients with the ability to maintain a conversation

The exclusion criteria will be:

1. patients with acute symptoms that may affect their consciousness.
2. patients with any uncontrolled symptoms that prevent collaboration in the study assessed according to clinical judgment
3. moderate or severe cognitive impairment assessed according to clinical judgment
4. patients included in another incompatible clinical trial

This study proposes a randomized controlled clinical trial (RCT) with a stepped-wedge design, in which 6 palliative care units from second and third level hospitals in Spain will collaborate. The six units will contribute with both experimental and control participants, starting with the recruitment of the control group participants and subsequently starting the intervention group. The time at which they will transition to the intervention will be chosen at random. The centers will be randomized to know at what point in the study they should begin the intervention and each center will be informed of the number of patients they should include in each of the groups. The clusters correspond to the different palliative care units that participate in the study. Six sequences will be carried out, seven periods with 4 patients in each period. Patients will be different in each of the periods.
