Lung cancer patients from both the intervention and the control group will complete validated questionnaires at baseline and then after 3, 6, 9, 12, 15 and 18 months (or until death for those with a survival of less than 18months) to assess their perceived collaboration between their FP and the oncology team (from an adaptation of Nielsen et al.'s validated questionnaire (2003)), their quality of life (from the EORTC-QLQ-C30), pain and other symptom relief (from the EORTC-QLQ-LC13), their level of distress, anxiety and depression (from the HADS), their self-efficacy (from an adaptation of Lorig et al.'s validated questionnaire (1996)). Several processes of care will also be measured at the same intervals: number of exchanges of information, number of visits to FP, number of answered/unanswered calls from FP, delay to return patients' calls, responsibility for care by FP at the terminal phase of cancer, service utilization (ER visits, hospitalization, community health services). The investigators will also measure in patients' principal family caregivers, their perceived collaboration between FP and the oncology team (same questionnaire than the one used for patients but adapted to family caregivers), their distress (from the IDPESQ), psychological burden (from the CBS-EOLC) and self-efficacy (same questionnaire than the one used for patients but adapted to family caregivers . Finally, measures related to FP will include their perceived collaboration with the oncology team (same questionnaire than the one used for patients and family caregivers but adapted to FPs).
