At least 25% of eligible patients agree to participate.

At least 80% of patients complete the study to the end. The study completion rate is calculated based on the difference between the number of patients enrolled in T0 and those who completed the study in T2.

At least 70% of patients complete all sessions regardless of the intervention arm. The weekly call includes a question asking participants whether they attended the week's session. Answer with Yes or No. If yes: go through all of the following questions. If no: investigate further to see if anything has been done."

At least 70% of patients complete all assigned between-session exercises. The weekly call includes a question asking participants if they have done their exercises throughout the week.

At least 70% of data are collected for the ecological momentary assessments.

At least 80% of patients rate the intervention as satisfactory. This percentage is calculated based on the response to one of the questions in the satisfaction questionnaire, which is 1-item, 6-point self-report questionnaire (0 = Not at all, 6 = Absolutely). The question investigates whether, overall, participants were satisfied with the intervention. Mean score is ≥ 4 in the satisfaction questionnaire. Satisfaction will also be assessed through a qualitative analysis (thematic analysis) of the transcript of the exit interview. The questionnaires were developed for this study.

At least 80% of patients would recommend the intervention to other patients. This percentage is calculated based on the response to one of the questions in the satisfaction questionnaire, which is 1-item, 6-point self-report questionnaire (0 = Not at all, 6 = Absolutely). The question investigates the extent to which participants would recommend this intervention to other patients in their situation. Mean score is ≥ 4 in the satisfaction questionnaire. The questionnaire was developed for this study.

No more than 10% of patients discontinue participation due to emotional distress or perceived burden linked to the intervention, as assessed by one question of the drop-out questionnaire which is: 'The reasons for this decision are related to: A.

Self-reported emotion impact will also be based on responses from the exit interviews (which is a semi-structured interview), assessed through a qualitative analysis (thematic analysis). The questionnaires were developed for this study.

The preliminary efficacy and interventions differences will be assessed using self-report questionnaires. The GAD-7, which is a validated 7-item, 4-point self-report questionnaire assessing anxiety symptoms. A higher score indicates higher levels of anxiety.

The preliminary efficacy and interventions differences will be assessed using self-report questionnaires. The PHQ-9 which is a validated 10-item, 4-point self-report questionnaire assessing depressive symptoms. A higher score indicates higher levels of depression.

The preliminary efficacy and interventions differences will be assessed using self-report questionnaires. The PSWQ which is a validated 16-item, 5-point self-report questionnaire assessing worry. A higher score indicates higher levels of worry.

The preliminary efficacy and interventions differences will be assessed using self-report questionnaires. The FCRI (Fear of cancer progression modified Fear of Cancer Recurrence Inventory) : which is a validated 42-item, 5-point self-report questionnaire assessing seven dimensions of fear of cancer recurrence (0 = Never, 4 = All the time): triggers, severity, psychological distress, coping strategies, functioning impairments, insight, and reassurance. This scale has been validated in patients with metastatic cancer. However, to simplify the understanding of the items, the investigators have adapted it by substituting "fear of cancer recurrence" by "fear of cancer progression". Higher score indicates higher levels of fear of cancer progression.

The preliminary efficacy and interventions differences will be assessed using self-report questionnaires.
