9 Background: We examined patient-reported fatigue scores and overall survival (OS) in patients with esophageal cancer (EC) enrolled in the Mayo Clinic Esophageal Adenocarcinoma and Barrett's Esophagus Registry (EABE). Methods: 1,481 patients enrolled in the EABE between September 2001 and January 2009 returned a baseline quality of life questionnaire including a Linear Analog Self Assessment (LASA) fatigue score which was scored on a 0-10 scale, with 0 as the most extreme fatigue. Patients were categorized as having clinically deficient fatigue (DF) if they reported a score of ≤ 5 and clinically non-deficient fatigue (nDF) if they reported a score of > 5. Kaplan-Meier methodology and Cox models explored OS in relation to fatigue scores in patients with EC. Results: A total of 667 patients with EC were included in the EABE, of which 659 returned a registry questionnaire with a valid LASA fatigue score recorded. Median age at the time of registry entry was 65 years (range 23-92). A total of 392 (59%) and 267 patients (41%) reported DF and nDF, respectively. On univariate analysis, patients with nDF had improved 5-year survival compared to patients with DF. In patients having esophagectomy prior to LASA, those reporting nDF had improved survival compared to patients with DF. Similarly, in patients having no esophagectomy prior to LASA, those with nDF had improved survival compared to those with DF. Among the 368 patients with locally advanced EC (LAEC), those reporting nDF had improved 5-year overall survival compared to patients with DF (28% vs 17%, HR = 0.67, p = 0.003). This remained significant on multivariate analysis (HR = 0.71, p = 0.015). Conclusions: Patient-reported fatigue is associated with overall survival in patients with LAEC. As a result, fatigue scores should be considered as a stratification factor in future clinical trial design. [Table: see text] No significant financial relationships to disclose.
