Qolp-15. Longitudinal Perception of Prognosis of Patients With High Grade Glioma Compared to Their Caregivers and Clinicians

Abstract

BACKGROUND Treatment options and prognosis are limited for patients with high grade glioma (pwHGG), underscoring the importance of patient and caregiver understanding to prioritize goals of care and quality of life (QOL). Although addressed by multiple providers, patients and caregivers may experience discordance in understanding the prognosis. This may be related to patient/caregiver perception, cognitive decline as a result of the tumor and/or treatment, or failure by the clinician to clearly articulate this information under emotional circumstances. AIMS: To evaluate the longitudinal perception of prognosis of patients compared to their caregivers and their providers during the adjuvant treatment of newly diagnosed HGG. METHODS After IRB approval, 16 pwHGG, their caregivers and their providers reported an overall survival estimate at each monthly visit during adjuvant treatment, as part of a larger survey. Options included “weeks,” “weeks to several months,” “several months to years,” “indefinite number of years”, or “I do not wish to answer.” RESULTS Seven of the sixteen patient/caregiver clusters have completed the appropriate duration of the study with the remaining completing in November. The perception of the patient differs from the caregiver at almost each visit. Regardless of the counseling provided by provider, the perception of both tends to change at each visit and can vary from dismal to overtly optimistic. There does not appear to be discrepancy between the neuro-oncology and palliative care provider’s perception of prognosis. CONCLUSION Newly diagnosed pwHGG and caregivers vary in their perception of prognosis, deviating not only from each other but also differing at each visit throughout the course of their illness. The providers’ perception appeared to remain consistent but often varied from that of the patient and caregiver. Providers need to be aware that prognostic understanding appears to fluctuate throughout the course of illness and cannot be clarified via a single discussion.

Overview of prognostic factors in adult gliomas

“…This prognostic discord can be very significant and may have implications at the end of life in terms of the distress it may cause as well as conflict in shared decision making. A small prospective pilot study of HGG patients and their caregivers noted that prognostic understanding fluctuated every month during adjuvant treatment, and varied widely from each other and from their providers (which remained quite static) (59).…”
