Cancer fatigue has been defined and described as an important problem. However, few studies have assessed the relative importance of fatigue compared with other patient symptoms and concerns. To explore this issue, the authors surveyed 534 patients and 91 physician experts from 5 NCCN member institutions and community support agencies. Specifically, they asked patients with advanced bladder, brain, breast, colorectal, head and neck, hepatobiliary/pancreatic, kidney, lung, ovarian, or prostate cancer or lymphoma about their “most important symptoms or concerns to monitor.” Across the entire sample, and individually for patients with 9 cancer types, fatigue emerged as the top-ranked symptom. Fatigue was also ranked most important among patients with 10 of 11 cancer types when asked to rank lists of common concerns. Patient fatigue ratings were most strongly associated with malaise (r = 0.50) and difficulties with activities of daily living, pain, and quality of life. Expert ratings of how much fatigue is attributable to disease versus treatment mostly suggested that both play an important role, with disease-related factors predominant in hepatobiliary and lung cancer, and treatment-related factors playing a stronger role in head and neck cancer.

Recent guidance from the FDA discusses patient-reported outcomes as end points in clinical trials. Using methods consistent with this guidance, the authors developed symptom indexes for patients with advanced cancer. Input on the most important symptoms was obtained from 533 patients recruited from NCCN Member Institutions and 4 nonprofit social service organizations. Diagnoses included bladder, brain, breast, colorectal, head and neck, hepatobiliary/pancreatic, kidney, lung, ovarian, and prostate cancers and lymphoma. Physician experts in each of these diseases were also surveyed to differentiate symptoms that were predominantly disease-based from those that were predominantly treatment-induced. Results are evaluated alongside previously published indexes for 9 of these 11 advanced cancers that were created based on expert provider surveys, also implemented at NCCN Member Institutions. Final results are 11 symptom indexes that reflect the highest priorities of people affected by these 11 advanced cancers and the experienced perspective of the people who provide their medical treatment. Beyond the clinical value of such indexes, they may also contribute significantly to satisfying regulatory requirements for a standardized tool to evaluate drug efficacy with respect to symptomatology.
