The decision to limit or discontinue treatment is a difficult issue, which all physicians will face. Timely communication with information on treatment possibilities and limitations, respectful listening to patients' and informal caregivers' wishes and early palliation is recommended in a stable phase. In some situations, it is better to stop life-prolonging treatment and optimise quality of life in patients with benign pulmonary diseases. Decision on treatment limitations or discontinuation is best taken at a conference and should be based on the patient's wishes, the disease stage and progression and potential reversible components.
