Pain and the choice to hasten death in patients with painful metastatic cancer.

Unrelieved pain has been cited as an important reason why cancer patients may seek to hasten their deaths. We interviewed 48 patients with painful metastatic cancer to ascertain their interest in various active and passive modes of hastening death. Ninety percent of these patients supported the general right of terminally ill patients to passive modes of hastening death and 80% supported the right to active modes such as assisted suicide and euthanasia. If they developed severe pain that could not be relieved, 80% would instruct their physician write a "do not attempt resuscitation" order, 40%-50% would want to receive suicide information or a lethal prescription from their physician, and 34% would request a lethal injection from their physician. Current pain and depression levels were not associated with interest in hastening death, but current somatic symptom burden was significantly associated with this interest.
