摘要

Purpose: Evaluate reliability and validity of the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire and its derivative FACT Hepatobiliary Symptom Indexes (FHSI-18 and FHSI-8) in people with metastatic pancreatic cancer. Methods: Self-reported questionnaire data from a randomized controlled Phase II study evaluating the efficacy and safety of conatumumab (AMG 655), ganitumab (AMG 479) or placebo combined with gemcitabine were evaluated. The following were assessed: internal consistency, using Cronbach's α; discriminant validity, comparing baseline patient-reported outcomes (PRO) scores across Eastern Cooperative Oncology Group (ECOG) performance status (PS) levels; and ability to detect change, comparing change from baseline PRO score at each cycle across PS and tumour response groups. Results: The analysis included 96 patients. All scale scores demonstrated good internal consistency (Cronbach's α > 0.7) and discriminant validity. Baseline scores were significantly poorer among patients with PS = 1 versus patients with PS = 0 (e.g. difference in FACT-Hep total score -17.27; p < 0.001). Ability to detect change was established for Cycles 2/3 versus baseline; PRO scores reduced in the PS-worsened group versus the PS-stable group (e.g. difference in FACT-Hep total score -24.29; p < 0.001). All PRO scale scores showed significant decline for progressive disease versus stable disease (e.g. difference in FACT-Hep total score -12.58; p = 0.004). Changes on the FHSI-18 and FHSI-8 scales were similar in magnitude whether ECOG improved or worsened. Conclusions: FACT-Hep detects change and is a reliable and valid instrument for measuring health-related quality of life in patients with metastatic pancreatic cancer.
