    Notizen: Mit dem Einsatz moderner Therapiestrategien gelingt es, die Mehrzahl der Patienten mit Morbus Hodgkin zu heilen. Nachdem auch in den fortgeschrittenen Stadien die Prognose deutlich verbessert werden konnte, können 85% der Patienten auf eine Heilung hoffen. Dieses wirft die Frage auf: “Was erwartet den geheilten Patienten?”. Hierbei ist zu unterscheiden zwischen den objektiven Ereignissen, die wir als Spätfolgen der Erkrankung und der Therapie kennen, und den Ereignissen, die sich vornehmlich im subjektiven Erleben der Patienten widerspiegeln. In den letzten Jahren ist es uns gelungen, gerade auf diesem Gebiet erhebliche Fortschritte zu erzielen. So ist es heute selbstverständlich, zur Beurteilung der allgemeinen Lebensqualität des Patienten dessen subjektive Einschätzung reproduzierbar zur Grundlage zu machen. Schon 1988 hat Murphy in einem Beitrag darauf hingewiesen, dass Lebensqualität (LQ) operationalisierbar und damit zuverlässig messbar ist. Hier gilt es allgemein, die immer noch vorherrschende Skepsis gegenüber der LQ-Forschung auszuräumen und gleichzeitig die Bedeutung der LQ-Einbußen, die den Patienten erwarten, anschaulich zu erklären. Im folgenden Artikel soll versucht werden, die als Therapiekomplikationen bekannten frühen und vor allem späten Folgen der Erkrankung und ihrer Therapie zusammenzufassen und die neuesten Erkenntnisse der LQ-Forschung wiederzugegeben.

    Notizen: Abstract Previous reports from available trials have dealt with negative long-term sequelae in Hodgkin's disease (HD) survivors. There is, however, a lack of longitudinal data showing the correlation between outcome and various treatment-related variables and the process of re-adaptation into normal life after the end of treatment. In order to investigate the quality of life (QoL) of patients with HD in different dimensions during active treatment and follow-up and to identify longitudinal patterns of QoL dimensions during re-adaptation to normal life within the EORTC Lymphoma Cooperative Group and Groupe D'Etude des Lymphomes de L'Adulte (EORTC/GELA) and the German Hodgkin Study Group (GHSG), QoL assessment strategies were put into use over the last three to five years. Furthermore, the efforts aimed at obtaining cross-cultural comparisons between the participating countries and study groups (EORTC/GELA and GHSG). Within the randomised EORTC/GELA Trial 'H8' for clinical stage I-II HD which started in September 1993, patients receive a QoL questionnaire for completion at each follow-up visit during the first 10 years after the end of active therapy. The corresponding 'HD8' study of the GHSG employs the assessment of QoL during and after active treatment periods. Within both studies, the EORTC QLQ C30 is used for QoL assessment incorporated in the QLQ-S (quality of life questionnaire for survivors), which additionally addresses the aspects of fatigue/malaise, sexuality, specific side effects, and retrospective evaluation of treatment. In total the QLQ-S includes 45 questions on 14 functional, symptom, and fatigue scales, 15 additional single items, and 3 open questions. In addition to the longitudinal QoL assessment, the GHSG carried out cross-sectional QoL trials with all cured surviving patients from the past HD1-6 studies and a matched normal control sample employing the QLQ-S and the life situation questionnaire (LSQ), an instrument covering objective data from 45 domains of life. To date, within the trials H8 and HD8 over 3000 QoL questionnaires from more than 800 patients from ten countries are available for analysis. Replication of the psychometric properties of the scales revealed satisfactory results using factor analyses and reliability testing across languages for the QLQ-S. A feasibility analysis showed generally a good acceptance of the questionnaire by the patients and physicians. QoL assessment within international multicentre trials in HD proved feasible within the two differently organised study groups of EORTC/GELA and GHSG. The use of subjective QoL data (QLQ-S) together with objective data (LSQ) in a combined cross-sectional and longitudinal trial system will give the most comprehensive insight into the problems of the re-integration process into normal life after cure. This information will provide the basis for the development of remedies/help measures and possible modifications of treatment strategies. The current approach will be further developed in close collaboration between both trial groups, and next steps will include translation of the LSQ into other languages and adaptation to various cultural circumstances.

    Beschreibung: Background We examined if cancer patients' health-related quality of life (HRQoL) scores on the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 are affected by the specific time point, before or during treatment, at which the questionnaire is completed, and whether this could bias the overall treatment comparison analyses. Patients and methods A ‘completion-time window’ variable was created on three closed EORTC randomised control trials in lung (non-small cell lung cancer, NSCLC) and colorectal cancer (CRC) to indicate when the QLQ-30 was completed relative to chemotherapy cycle dates, defined as ‘before’, ‘on’ and ‘after’. HRQoL mean scores were calculated using a linear mixed model. Results Statistically significant differences ( P  〈 0.05) were observed on 6 and 5 scales for ‘on’ and ‘after’ comparisons in the NSCLC and two-group CRC trial, respectively. As for the three-group CRC trial, several statistical differences were observed in the ‘before’ to ‘on’ and the ‘on’ to ‘after’ comparisons. For all three trials, including the ‘completion-time window’ variable in the model resulted in a better fit, but no substantial changes in the treatment effects were noted. Conclusions We showed that considering the exact timing of completion within specified windows resulted in statistical and potentially clinically significant differences, but it did not alter the conclusions of treatment comparison in these studies.

    Beschreibung: Introduction As patient assessment of health-related quality of life (HRQOL) in cancer clinical trials has increased over the years, so has the need to attach meaningful interpretations to differences in HRQOL scores between groups and changes within groups. Determining what represents a minimally important difference (MID) in HRQOL scores is useful to clinicians, patients and researchers, and can be used as a benchmark for assessing the success of a healthcare intervention. Our objective is to provide an evidence-based protocol to determine MIDs for the European Organisation for Research and Treatment for Cancer Quality of life Questionnaire core 30 (EORTC QLQ-C30). We will mainly focus on MID estimation for group-level comparisons. Responder thresholds for individual-level change will also be estimated. Methods and analysis Data will be derived from published phase II and III EORTC trials that used the QLQ-C30 instrument, covering several cancer sites. We will use individual patient data to estimate MIDs for different cancer sites separately. Focus is on anchor-based methods. Anchors will be selected per disease site from available data. A disease-oriented and methodological panel will provide independent guidance on anchor selection. We aim to construct multiple clinical anchors per QLQ-C30 scale and also to compare with several anchor-based methods. The effects of covariates, for example, gender, age, disease stage and so on, will also be investigated. We will examine how our estimated MIDs compare with previously published guidelines, hence further contributing to robust MID guidelines for the EORTC QLQ-C30. Ethics and dissemination All patient data originate from completed clinical trials with mandatory written informed consent, approved by local ethical committees. Our findings will be presented at scientific conferences, disseminated via peer-reviewed publications and also compiled in a MID ‘blue book’ which will be made available online on the EORTC Quality of Life Group website as a free guideline document.

    Beschreibung: Background: The European Organisation for Research and Treatment of Cancer (EORTC) Patient-Reported Outcomes and Behavioural Evidence (PROBE) initiative was established to investigate critical topics to better understand health-related quality of life (HRQOL) of cancer patients and to educate clinicians, policy makers, and healthcare providers. Methods: The aim of this paper is to review the major research outcomes of the pooled analysis of HRQOL data along with the clinical data. We identified 30 pooled EORTC randomized controlled trials (RCTs), 18 NCIC-Clinical Trials Group RCTs, and two German Ovarian Cancer Study Group RCTs, all using the EORTC QLQ-C30. All statistical tests were two-sided. Results: Evidence was found that HRQOL data can offer prognostic information beyond clinical measures and improve prognostic accuracy in cancer RCTs (by 5.9%-8.3%). Moreover, models that considered both patient- and clinician-reported scores gained more prognostic overall survival accuracy for fatigue ( P 〈 .001), vomiting ( P = .01), nausea ( P 〈 .001), and constipation ( P = .01). Greater understanding of the association between symptom and/or functioning scales was developed by identifying physical, psychological, and gastrointestinal clusters. Additionally, minimally important differences in interpreting HRQOL changes for improvement and deterioration were found to vary across different patient populations and disease stages. Finally, HRQOL scores are statistically significantly affected by deviations from the intended time point at which the questionnaire is completed. Conclusions: The use of existing pooled data shows that it is possible to learn about general aspects of cancer HRQOL and methodology. Our work shows that setting up international pooled datasets holds great promise for understanding patients’ unmet psychosocial needs and calls for additional empirical investigation to improve clinical care and understand cancer through retrospective HRQOL analyses.
