Abstract
Purpose: Because of cancer's high symptom burden and specific disease course, patients with cancer are more likely than other patients to face end-of-life decisions that have possible or certain life-shortening effects (ELDs). This study examines the incidence of ELDs in patients with cancer compared with patients without cancer and the trends in ELD incidence from 1998-2007. Patients and Methods: A nationwide death certificate study in Flanders, Belgium, was conducted in 2007, analogous to one completed in 1998. Physicians who had signed selected death certificates (n = 6,927) were sent a questionnaire. Results: The response rate was 58.4%. Nonsudden deaths were studied. Intensified symptom alleviation occurred more in patients with cancer than in those without (53.8% v 31.7%; P < .001) as did euthanasia (6.8% v 0.9%; P < .001). There was no difference between groups in nontreatment decisions and life-ending acts without patient's explicit request. Patients with cancer were less involved in the end-of-life decision-making process than patients without cancer (69.7% v 83.5%; P = .001). From 1998 to 2007, ELD incidence has increased in patients with cancer (+6.7%) and even more in patients without cancer (+14.9%) because of an increase in intensified symptom alleviation. In patients with cancer, euthanasia rates increased strongly and life-ending acts without the patient's explicit request decreased. Conclusion: The higher ELD incidence in patients with cancer compared with those without is probably related to differences in disease trajectories and access to end-of-life care. During the period from 1998 to 2007, when euthanasia was legalized and palliative care intensified, overall ELDs increased, including those as a result of symptom alleviation and euthanasia, with a decrease in life-ending acts without explicit request.
