[The decision to withdraw specific treatments in oncology].

Shared medical decision-making is a complex process, especially with regard to the withdrawal of specific treatments in oncology. On the one hand, patients, particularly vulnerable due to their advanced disease, and their family, apprehend this withdrawal. On the other hand, oncologists have more and more treatment options available to them thanks to the medical advances made over recent years. An observational prospective study was carried out in oncology. It focused on the motives which led to the question of treatment withdrawal being raised, to the degree of agreement between the different parties (palliative care team, oncologist, patients and families) and on the final decision.
