To study the clinical presentation of lung cancer patients at our palliative care unit (PCU).,We examined the clinical presentation of lung cancer patients at our PCU and compared it with the clinical presentation of patients with malignant tumors besides those indicative of lung cancer.,The PCU occupancy ratio of lung cancer patients to inpatients was 24%, which was dependent on the type of carcinoma. Lung cancer patients in need of oxygen inhalation and/or terminal sedation were more in number than those with other types of malignant tumors. On the other hand, few patients needed treatment. Dyspnea is the major reason for the terminal sedation of lung cancer patients.,Severe dyspnea appeared to be the typical clinical presentation of terminal-phase lung cancer patients.
