Communicating With Patients on Cancer Resistance to Treatment: the Development of a Communication Tool. (HECTOR)

Study Overview
=================
Brief Summary
-----------------
Resistance to treatment is one of the major themes in cancer research. Despite this, the definition and clinical implications of resistance to treatment remain under-explored, and patient-physician communication in this context still constitutes a challenge. When resistance to cancer treatments occurs, physicians not only have to explain to the patient the phenomenon of resistance, often based on complex results (biological results, genomic tests, imaging, etc.), but also need to offer alternative therapies, whilst fostering shared medical decision-making. These different tasks are particularly challenging for clinicians, especially since there are large individual differences at patient level. Indeed, each patient has his or her own unique information needs, capacity for understanding, and level of desire to participate in treatment decisions.

Detailed Description
-----------------
Although a challenge, better communicating around resistance to treatment carries many potential benefits. Indeed, in similar contexts of announcement of bad news and choice of care, Parker and collaborators (1) have highlighted the positive impact of individualized care, respecting the needs, quality of care, and quality of life of patients. Given the clinical stake, and the lack of scientific knowledge devoted to communication in the context of resistance to treatment, it appears necessary to better understand its modalities. In this perspective, research has proven the value of tools for supporting communication, including the issue of question booklets for patients. These tools provide patients with a list of questions submitted to them before the medical consultation, and which they can ask during the consultation, and throughout the treatment. This tool fosters communication by helping the patient obtain a level of information that is adapted to his or her needs and experience, and thus, to be better prepared for care. Despite significant interest for these booklets in the field of oncology, none has yet been developed in the specific context of resistance to treatment.

Design Details

Primary Purpose: Other
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Interventional Model Description: To meet our objectives, the research team has developed a cross-sectional and mixed exploratory research according to three successive steps : Step 1: Questionnaires and semi-structured individual interviews will : (a) to identify patients' needs and (b) to build the initial contents of the tool, items and issues. Four patients' populations will be recruited in this step : metastatic uveal melanoma, triple negative breast cancer, luminal B breast cancer, and pediatric cancer. This step will be conducted in parallel with these populations. Step 2 : Focus groups : to evaluate the acceptability and applicability of the tool in this clinical context with expert patients, researchers and clinicians. Step 3 : The DELPHI consensus method : to validate the contents of the booklet for patients with expert patients, researchers and clinicians.
Masking: None (Open Label)
