[The announcement of treatment resistance in pediatric oncology: Understanding parents' experiences and influencing factors with a mixed methodology]. / L'annonce de résistance au traitement en oncologie pédiatrique : une étude avec une méthodologie mixte pour comprendre l'expérience des parents et les facteurs qui l'influencent.

OBJECTIVE: The announcement of a resistance to treatment in pediatric oncology occurs within the framework of an established parent-pediatrician relationship. The aim of this study was to understand the parents' experience of this announcement and the relational and communicational factors likely to impact it. METHOD: A mixed-methods study was conducted in a pediatric oncology department with 15 parents of a child with treatment-resistant cancer, with an average age of 40.8years. The parents completed three questionnaires to assess their anxiety and depression (HADS) and their information needs (EORTC - QLQ Info 25 and PTPQ). Semi-structured interviews were conducted and a content analysis was performed. RESULTS: The majority of parents have "suspected" or "proven" anxiety and/or depressive disorders. The experience of this announcement was influenced by the quality of the parent-pediatrician relationship, the perceived quality of the management, the anticipation of the announcement, the context of the announcement, and the experience of previous announcements. The parents interviewed were very satisfied with the informational exchanges. This satisfaction was underpinned by honest communication and by the responsiveness and availability of the pediatricians. DISCUSSION: The establishment of a relationship of trust between the family and the pediatrician throughout the course of care plays a major role in the parents' experience of the announcement of resistance to treatment.
