Viewpoints on the Social Representations and Rationale Concerning the Choices of Patients, Doctors and Caregivers With Regard to the Management of Patients With Non-resectable Metastatic Cancer of the Colon, Stomach, Bile Ducts, Rectum, Pancreas or Lung, or Gastrointestinal Neuroendocrine Tumours

Study Overview
=================
Brief Summary
-----------------
Reflexion on the therapeutic strategies to implement in patients at the end of life is advancing rapidly in France. However, beyond the choices presented to patients, sometimes even the decision to carry on, to limit or to stop treatments is also questioned. This decision is subjective; it is influenced by the patient's representation system (emotions, beliefs, values, practices, etc). In addition, even though he or she is the focus of the decision, the patient is not alone; other actors, accompanying the patient, play an important role in the final decision making. These actors, namely the doctors and close relatives, are also influenced in their decision making. This coexistence of representation systems may interfere with objective indicators that help in decision making (functional, clinical and biological) or with the knowledge acquired by doctors in their training and may complicate the decision-making process.
