[Current developments in measuring quality of life with instruments of the European organisation for research and treatment of cancer (EORTC)]. / Aktuelle Entwicklungen bei der Erfassung der Lebensqualität mit Instrumenten der European Organisation for Research and Treatment of Cancer (EORTC).

Since many years, the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Group develops and validates measures for the assessment of quality of life in cancer patients, using high standards of methodology. These questionnaires are meant to be used primarily in clinical trials.As treatment strategies are changing and because of some -methodological criticism, the head and neck module EORTC QLQ-H&N35 is currently being revised and updated.In this paper, we will present the current state of work and other recent developments regarding the EORTC Quality of Life questionnaire development.

Age- and sex-standardised prevalence rates of fatigue in a large hospital-based sample of cancer patients.

BACKGROUND: The aim of this longitudinal study was to determine age- and sex-standardised prevalence rates of cancer-related fatigue in different groups of patients. METHODS: This was a prospective study in a cohort of N=1494 cancer patients investigating fatigue at three time points t1-t3 (t1: admission to hospital, t2: discharge, t3: half a year after t1). Fatigue was measured with the Multidimensional Fatigue Inventory. Age- and sex-adjusted norms were derived from a representative community sample of N=2037, using a cutoff at the 75th percentile. RESULTS: At admission to the hospital, 32% of the patients were classified as fatigued. At discharge, the overall prevalence rate was 40%, and at half a year after t1, prevalence was 34%. Fatigue prevalence rates differed according to tumour stage, site, age, and sex of the patients. CONCLUSION: The prevalence rates provided by this study can be used for the planning of research and clinical routine.
