Quality of life of acute myeloid leukemia patients in a real-world setting.

e18525 Background: There is currently limited data on the quality-of-life (QoL) of patients with acute myeloid leukemia (AML) in the real-world setting. The objective of this analysis was to understand the impact of AML on patients receiving first-line treatment vs those who were relapsed/refractory to first-line treatment and therefore on later lines of therapy. Methods: The Adelphi AML Disease-Specific Programme, a real-world, cross-sectional survey involving 61 US hematologists/hemato-oncologists and their consulting AML patients, was conducted between February–May 2015. Physicians provided details on patient demographics and clinical information. Each patient was asked to complete both the EQ-5D-3L and Functional Assessment of Cancer Therapy Leukemia (FACT-Leu). Scores range from −1.09–1 (EQ-5D-3L) and 0–176 (FACT-Leu), where a higher score indicates a better QoL. Data from physician-completed record forms and corresponding patient self-completion forms on a matched sample of 75 patients were analyzed. Results: Of the patients who took part in the survey, 75% (n = 56) were receiving first-line treatment for AML and 25% (n = 19) were relapsed/refractory to first-line treatment and had progressed to later lines of therapy. The first-line patients had a mean age of 56.6 years and an average of 2.1 symptoms whereas the relapsed/refractory patients had a mean age of 56.9 years and an average of 2.4 symptoms, according to the physician. First-line patients may have a directionally better QoL scores than those on later lines of therapy, according to both the EQ-5D (0.75 and 0.71 respectively, P= .51) and the FACT-Leu (103.7 and 92.5 respectively, P= .098) measures. Results from the FACT-Leu-Physical Well-Being sub-domain show that relapsed/refractory patients were significantly more likely than first-line patients to be affected physically by their AML condition (13.0 and 17.6 respectively, P= .005). Conclusions: AML patients who have relapsed or become refractory to first-line treatment report worse QoL than those still on first-line treatments. These observational data shows a need for effective and tolerable treatments that can maintain or improve patients’ QoL, especially for patients with relapsed or refractory disease.
