This is a prospective observational study done on 3 patient populations (cancer, chronic pulmonary and renal disease). All patients will be treated and monitored according to the local clinical practice. No additional procedures/patient visits in comparison with the usual clinical practice are planned for the study. The primary objective is to analyze appropriateness and timeliness of progressive palliative care approach (initially simultaneously with ongoing disease-oriented treatment and subsequently possibly as the only modality of care to avoid aggressiveness of care) in patients with:
* First diagnosis of advanced metastatic non-small cell lung cancer, or advanced gastric cancer or advanced pancreatic adenocarcinoma
* advanced chronic respiratory failure, caused by chronic obstructive pulmonary disease (COPD) or idiopathic pulmonary fibrosis (IPF).
* advanced chronic renal failure
