QOL-02. SOCIAL NETWORKS CAN BE QUANTITATIVELY MEASURED AND NETWORKS WITH GREATER STRUCTURAL DIVERSITY ARE ASSOCIATED WITH HIGHER HUMAN FLOURISHING

Abstract BACKGROUND In patients with glioblastoma, the predicted progressive deterioration in physical and cognitive abilities leads to decreased quality of life for patients and their caregivers. Research has shown that one’s social environment is a major contributor to health outcomes. However, in this population, study of the social environment is a gap in the literature. METHODS We examined the personal social networks of 25 adult glioblastoma patients at one time between initial diagnosis and first cycle of adjuvant chemotherapy from March to September 2023. We additionally collected demographic, tumor measures, and the European Organization for Research and Treatment of Cancer Quality-of-Life for Patients with Brain Tumors (EORTC QLQ-BN20) and the Harvard Human Flourishing Index (HFI) measures. RESULTS The average age was 64.5 years old, 56% were female, and 84% had a Karnofsky Performance Status (KPS) of 70 or higher. Patients had large network sizes (mean of 8.8). Patients reported high levels of flourishing despite the challenging diagnosis. Flourishing was statistically significantly associated with lower network constraint (networks in which alters are less likely to be connected to each other) in a patient’s social network (p=0.046) and less lower extremity weakness (p=0.025), controlling for age, gender, income, tumor at size of diagnosis, and KPS. CONCLUSION Our study indicates personal social networks with more contacts who are not connected to each other are associated with greater flourishing. Quantifying the social networks of patients with glioblastoma has implications as an objective measure for supportive care trials. Moreover, standard quality-of-life measures may not adequately capture what it means to meaningfully live and flourish. Therefore, future studies should include how social networks and flourishing change over the course of illness and how this may also impact overall survival.
