Abstract
BACKGROUND: We describe patient-reported outcomes (PROs) in adults with CNS tumors and evaluate their correlation with physician-reported functional status. METHODS: We completed a retrospective cohort study of patients managed at a high-volume CNS tumor institute between September 2013 and September 2014. PROs were measured using 6 domains from the PROs Measurement Information System (PROMIS): anxiety, physical function, pain interference, sleep disturbance, fatigue, and satisfaction with social roles. Physician-reported outcomes were measured using the Eastern Cooperative Oncology Group Scale of Performance Status (ECOG). We compared differences in PROMIS scores across tumor types using analysis of variance and measured the correlation between PROMIS scores and ECOG scores using spearman correlations. Finally, we compared the range of PROMIS physical function scores within each ECOG level. RESULTS: In a cohort of 2,828 patients, 1,284 (45.4%) completed all 6 PROMIS domains. There were significant differences in PROMIS scores across tumor types for all domains except anxiety. The strength of the correlation between PROMIS and ECOG scores was weak to moderate for all PROMIS domains (all p < 0.001). The correlation was the strongest between the physical function domain and ECOG score (ρ = -0.54), although there was a broad distribution of physical function scores within ECOG level, with scores spanning nearly 5 SDs within most ECOG levels. CONCLUSIONS: Symptom burden was associated with tumor type. There were only weak to moderate correlations between PROMIS and ECOG scores, underscoring the importance of integrating PROs into clinical practice for patients with CNS tumors.
