Is shared decision-making vanishing at the end-of-life? A descriptive and qualitative study of advanced cancer patients' involvement in specific therapies decision-making.

BACKGROUND: Little is known about what is at stake at a subjective level for the oncologists and the advanced cancer patients when they face the question whether to continue, limit or stop specific therapies. We studied (1) the frequency of such questioning, and (2) subjective determinants of the decision-making process from the physicians' and the patients' perspectives. METHODS: (1) All hospitalized patients were screened during 1 week in oncology and/or hematology units of five institutions. We included those with advanced cancer for whom a questioning about the pursuit, the limitation or the withholding of specific therapies (QST) was raised. (2) Qualitative design was based on in-depth interviews. RESULTS: In conventional units, 12.8 % of cancer patients (26 out of 202) were concerned by a QST during the study period. Interviews were conducted with all physicians and 21 advanced cancer patients. The timing of this questioning occurred most frequently as physicians estimated life expectancy between 15 days and 3 months. Faced with the most frequent dilemma (uncertain risk-benefit balance), physicians showed different ways of involving patients. The first two were called the "no choice" models: 1) trying to resolve the dilemma via a technical answer or a "wait-and-see" posture, instead of involving the patients in the questioning and the thinking; and 2), giving a "last minute" choice to the patients, leaving to them the responsibility of the decision. In a third model, they engaged early in shared reflections and dialogue about uncertainties and limits with patients, proxies and care teams. These schematic trends influenced patients' attitudes towards uncertainty and limits, as they were influenced by these ones. Individual and systemic barriers to a shared questioning were pointed out by physicians and patients. CONCLUSIONS: This study indicate to what extent these difficult decisions are related to physicians' and patients' respective and mutually influenced abilities to deal with and share about uncertainties and limits, throughout the disease trajectory. These insights may help physicians, patients and policy makers to enrich their understanding of underestimated and sensitive key issues of the decision-making process.

Parenteral nutrition at the palliative phase of advanced cancer: the ALIM-K study protocol for a randomized controlled trial.

BACKGROUND: Malnutrition is a common complication in patients at the palliative stage of cancer. During the curative phase of cancer, optimal enteral or parenteral nutrition intake can reduce morbidity and mortality, and improve quality of life. When the main goal of treatment becomes palliative, introduction of artificial nutrition is controversial. Although scientific societies do not recommend the introduction of artificial nutrition in all cases of malnutrition, especially in hypophagic patients if their life expectancy is shorter than 2 months, considerable differences in the use of parenteral nutrition in nonsurgical oncology practice are noted around the world. One explanation is a paucity of well-conducted randomized controlled trials in these situations, and consequently, the risk/benefit ratio of parenteral nutrition and its impact on quality of life in palliative care remains uncertain. METHODS/DESIGN: The ALIM-K study is a French national multicenter randomized controlled trial designed to evaluate the effectiveness of parenteral nutrition, versus an exclusive oral-feeding supply, on the quality of life of malnourished patients who have a functional digestive tube and who are at the palliative phase of advanced cancer with a life expectancy of more than 2 months. DISCUSSION: This article presents the methodologic options chosen for our study, and in particular, the choice of the Zelen method of randomization, the definition of the main end point (quality of life), the choice of comparator (oral feeding), and the inclusion criteria (life expectancy of more than 2 months), which are all critical points in building a randomized controlled trial in the setting of palliative care. TRIAL REGISTRATION: This study was registered with the clinical trials database ClinicalTrials.gov on May 27, 2014, under the number NCT02151214.
