ABSTRACT
OBJECTIVES: The aim of this study is to describe determinants of quality of life (QOL) quoted by vulnerable older patients with cancer and compare them with domains included in cancer-specific QOL questionnaires. MATERIAL AND METHODS: This prospective, monocenter, observational study was performed in a French university hospital. Cancer patients Patients with cancer aged over 74 years were recruited when referred for an out-patient geriatric evaluation (n = 102). After geriatric assessment, they were invited to respond to open-ended questions, Q1: "For you, what is most important to have a good QOL?" Q2: "What could improve your QOL?" Q3: "What could worsen your QOL?" A Delphi process was conducted to categorize patient responses according to content analysis. RESULTS: The most frequently patient-reported determinants for high quality of life were maintaining close ties with family/friends or social relations, autonomy for decision and mobility without depending on others, being in good health, not suffering from pain and the absence of problems concerning relatives. Global health status, physical functioning/mobility, social functioning and worries about others were the more frequently mentioned QOL domains related to the EORTC QLQ-C30 and ELD14 questionnaires. Some determinants of QOL were not linked to pre-defined domains, some others without a 100% consensus after the Delphi process, illustrating the subjectivity of QOL analysis by a single practitioner. CONCLUSION: Patient interview with open-ended questions provides valuable supplementary information to QOL questionnaires, in order to personalize health related (cancer treatment, pain management ) and global (maintenance of autonomy and family/social relations ) assessment and intervention.
