Dehydration is a common symptom in terminally ill cancer patients, a suffering not only to the patients, but also to the families. Is there appropriate guideline of artificial nutrition and hydration in terminally ill cancer patients at the end of life? Patients and families should be allowed to make decisions about artificial nutrition and hydration in an informed consent process that is guided under well-established principles. Health providers must ensure the decision and patient’s preference are respected. We hope terminally ill cancer patients can receive high-quality, compassionate care near the end of life.
