For terminal-phase cancer patients, being discharged from a palliative care unit(PCU)is often challenging. To explore this reason, we compared patients who went home alive from the PCU with patients who died in the same unit. Among the survival cases, the average duration from their diagnosis to admission into the PCU was longer. Their slow progressions might allow them to leave the PCU. Patients with head and neck cancer were more often among those who died in the PCU, and the ratio of patient with endometrial cancer was higher in the survival cases. These ratios were relevant to the duration before their admission and variety of their symptoms.
