Abstract
The objective of this study was to use survival-weighted psychometric scores (SWPS) to construct a 'health profile' for long-term survivors of acute myelogenous leukemia (AML). The study cohort included all patients who had been diagnosed and treated in our institution from 1985 to 1999 and achieved complete remission after standard chemotherapy (n = 259). One hundred and four patients were interviewed by the European Organization for the Research and Treatment of Cancer (EORTC)-QLQ-C30 questionnaire and the brief form of World Health Organization quality of life questionnaire (WHOQOL-BREF) to estimate the quality of life (QOL) function of the cohort. Forty-one patients underwent bone marrow transplantation (BMT) as consolidation or salvage therapy; 63 received chemotherapy alone. SWPS for every functioning domain and symptom item was obtained by direct integration of the mean QOL function with the survival function of the cohort. A Monte Carlo method was used to extrapolate the life-long SWPS beyond the follow-up limit. The mean scores of EORTC-QLQ-C30 and WHOQOL-BREF did not differ significantly between patients who received BMT or those who received chemotherapy only (p > 0.01). In mean SWPS, patients who received BMT had significantly (p < 0.01) better SWPS in all of the functioning domains and symptom items of EORTC-QLQ-C30 and all four domains of WHOQOL-BREF. However, when the life-long extrapolation of SWPS was made, these differences diminished in global health and several symptom items of EORTC-QLQ-C30 as well as in the social and environmental domains of WHOQOL-BREF. Patients' perspective on QOL may be domain-specific and may evolve over time. SWPS may be useful to evaluate the efficacy of different treatment strategies for AML. Confirmation of the relative merit of BMT vs. chemotherapy alone from prospective studies is needed.
