Patients with advanced cancer experience multiorgan failure, with many physical and psychological symptoms. Patients seek relief of suffering at the end stage of their lives.1 Consequently, the essential component of palliative cancer care is to provide them with symptom relief and better quality of life.2, 3 This may be challenging, and health care providers may have difficulty in developing symptom management strategies that can be applied across acute and home care settings.4 A lack of sufficient knowledge regarding effective therapeutic strategies is one of numerous factors that could interfere with adequate management of pain, depression and fatigue, and other symptoms.5 Thus, how to alleviate patients' symptoms is still a core issue in palliative care.
