Comprehension and Decision-Making Capacity Questionnaire About Palliative Care and Advance Care Planning: A Delphi Study.

Objective(s): To develop a questionnaire that assesses the level of comprehension and decision-making capacity of patients with breast cancer about palliative care and advance care planning. Methods: Questionnaire items were based on the scientific literature. Delphi Consensus, a three-round survey with experts (n = 14), evaluated the relevance, clarity, and redundancies of the items. A pretest with breast cancer patients (n = 15) evaluated whether they comprehended each item and identified doubts or discomforts. Results: The initial questionnaire was composed of 38 items. After the Delphi, 18 items were restructured, six were added, and 16 were removed. In the pretest phase, all items with the survey header, guidelines, and Likert model were evaluated. All items accomplished ≥80% cut-off score and were kept as in the original version. The final version of the questionnaire have 28 itens and five domains: determination, responsibility, independence, self-knowledge, and knowledge of reality. Conclusions: This study represents the first step in the development of a questionnaire that may be used in oncology clinical practice. The main findings revealed that Delphi and pretesting increased the quality of the questionnaire, making it compelling to assess breast cancer patients' comprehension and decision-making capacity about PC and ACP.

Impact of AferBio® on quality of life and chemotherapy toxicity in advanced lung cancer patients (AFERBIO study): protocol study for a phase II randomized controlled trial.

BACKGROUND: Lung cancer patients undergoing palliative chemotherapy exhibit many symptoms related to the disease, such as adverse events and infectious complications during treatment, which impacts directly their health-related quality of life (HRQOL). Nutritional status is a relevant aspect among advanced cancer patients under palliative care and food supplementation has the potential to reduce treatment-related adverse effects and improve the nutritional status. The product named AferBio® is a fermented supplement that has been described as able to provide some benefits, including the capacity to potentiate the effects of anticancer drugs, by promoting the reduction of side effects and ultimately improving HRQOL. METHODS/DESIGN: A Phase II double-blind placebo-controlled randomized clinical trial to assess the use of food supplementation with AferBio® in Stage IIIB or IV non-small cell lung cancer (NSCLC) patients beginning a second-line palliative mono-chemotherapy. The primary goal is to compare HRQOL scores between the arms of the study over time. The ten first patients included in the present study will undergo an AferBio®toxicity-testing (non-randomized phase). If no significant toxicity is found, the study will move on to the randomized phase. All patients will be randomized in blocks at a 1:1 ratio using the online tool REDCap. ECOG-PS (0-1 versus 2) criteria will be used for stratification. All patients included in the trial will be evaluated at baseline and at each chemotherapy cycle. Each evaluation will include the following: HRQOL (EORTC QLQ-C30, LC13 and IQualiV-Lung), ECOG-PS, anthropometric measurements, clinical and laboratory toxicity assessment and response evaluation. DISCUSSION: During palliative systemic therapy in advanced cancer patients, one of the main goals is the improvement and maintenance of HRQOL, which can be negatively affected by cancer symptoms, cancer- or treatment-related psychosocial difficulties, and chemotherapy toxicity. Thus, much research has been dedicated to the development of new and more effective and/or less toxic cancer therapies. The present study is justified by the testing of a novel food supplement that may reduce some toxicities, thus, having a potential positive impact on the HRQOL of lung cancer patients. The product in question (AferBio®) is already available for sale in Brazil, but has not yet been fully tested in cancer patients. TRIAL REGISTRATION: This Trial was registered on March 19, 2018 with ClinicalTrials.gov , NCT03469063. Protocol version: 2.0 from March 26, 2018. Trial status: Patient enrollment in the study began in April, 2018.
