[Overtreatment at the End of Life in Oncology]

Overtreatment at the End of Life in Oncology Abstract. The term overtreatment refers to situations, in which we evaluate the use of diagnostic or therapeutic measures negatively. On the one hand, these negative judgments refer to questionable scientific foundations of using respective measures. On the other hand, we challenge the adequacy of using medical measures in the context of overtreatment with reference to principle of beneficence. To determine the indication of medical measurements in a medically and ethically reflected way may serve as one starting point for avoiding overtreatment. Over the last two decades numerous studies, mainly in the United States of America and Europe, have shown that the use of anticancer treatments at the end of life has increased considerably. Moreover, the overuse of chemotherapy or targeted therapeutic agents as well as radiotherapy in terminally ill cancer patients in the last months of life was associated with an increased risk of undergoing cardiopulmonary resuscitation, mechanical ventilation or both and of dying in an intensive care unit. More recently, early provision of palliative care for patients with incurable cancer has gained increased attention as a feasible and efficacious approach for improving quality of life. Therefore, the doctor-patient communication is central for the avoidance of overtreatment. It should clarify not only the patient's wishes and priorities, but also his or her understanding of the approaching end of life. In spite of this, both is not the norm in everyday clinical practice; the reasons are to be found in a lack of training, structural obstacles, but also projections and assumptions on both sides. An early and structured approach, if necessary with the help of palliative medicine, can reduce these deficiencies.
