PURPOSE The European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) is a well-validated instrument that assesses health-related quality of life (HRQOL) in cancer patients. It is used in cancer clinical trials in Europe, Canada, and the United States, and has demonstrated high reliability and validity in different groups of cancer patients. Despite thorough testing of reliability and validity, we have not identified any reports on its test/retest reliability; thus, a test/retest study was performed at the Norwegian Radium Hospital (NRH). MATERIALS AND METHODS Cancer patients from the outpatient clinic who were off treatment for > or = 3 months were eligible for the study. The EORTC QLQ-C30 was given to the patients when they presented for their visit. The second questionnaire was received by the patients 4 days later. Of 291 eligible patients, 270 (93%) agreed to participate and 190 (73%) completed both questionnaires. RESULTS The test/retest reliability measured by Pearson's correlation coefficient was high for all functional scales, with a range from .82 for cognitive and role function to .91 for physical function. The r value for global HRQOL was .85. For the symptom scales--nausea/vomiting, fatigue, and pain--the coefficients were .63, .83, and .86, respectively. The single-item coefficients ranged from .72 for diarrhea to .84 for financial impact. The Spearman rank correlation was in the same range for all dimensions. CONCLUSION The EORTC QLQ-C30 seems to yield high test/retest reliability in patients with various cancer diagnoses whose condition is not expected to change during the time of measurement.

Objective: Recent years have shown an increase in the use of questionnaires measuring health-related quality of life to verify the quality of treatment in the field of oncology. An often used cancer-specific questionnaire is the “Quality of Life Core Questionnaire of the European Organization for the Research and Treatment of Cancer” (EORTC QLQ-C30). The purpose of this study is to analyze the psychometric properties of the EORTC QLQ-C30 (version 1) in order to determine the feasibility and appropriateness for its use in inpatient cancer rehabilitation in Germany with heterogeneous diagnoses.Methods: The questionnaire was administrated to a sample of 972 cancer patients at the beginning of treatment and to 892 patients after treatment. Besides descriptive analysis, the statistical analyses include confirmatory analysis and the multitrait/multimethod approach to test the questionnaire's postulated scale structure (factorial validity) and its reliability (internal consistencies). The analysis also includes a comparison of responsiveness indices (effect size, reliable change index) to test the sensitivity of the instrument.Results: The EORTC QLQ-C30 showed satisfactory levels of reliability and sensitivity, but the postulated scale structure could not be confirmed. The results illustrate that the varimax-rotated solution of a principal component analysis does not confirm the scale structure postulated by the authors. Correspondingly, the selected fit indices within the scope of the confirmatory factor analysis do not show satisfactory results either.Significance of results: We therefore consider version 1 of the EORTC QLQ-C30 to be only limitedly useful for the routine assessment of changes in the quality of life of cancer patients in inpatient rehabilitation in Germany, especially because of the instrument's length and possible redundancies. For this reason, a scoring procedure limited to a subset of items is suggested, revealing satisfactory to good psychometric indices. However, further psychometric tests are necessary, especially with regard to validity and sensitivity.

Abstract Purpose Cancer is of increasing prevalence in less-developed countries. However, research on the patients’ quality of life (QoL) in these countries is very limited. The aim of this study was to examine QoL of cancer patients in Africa. Method A sample of 256 cancer patients treated in an Ethiopian hospital was examined with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire EORTC QLQ-C30, the Multidimensional Fatigue Inventory, and the Hospital Anxiety and Depression Scale. A group of 1664 German cancer patients served as a comparison group. Results Most of the scales of the EORTC QLQ-C30 showed acceptable reliability in the Ethiopian sample. Compared with the German cancer patients, the Ethiopian patients showed lower QoL in most dimensions, especially in financial difficulties, physical functioning, pain, and appetite loss (effect sizes between 0.52 and 0.75). Illiteracy, tumor stage, and treatment (surgery and chemotherapy) were associated with QoL in the Ethiopian sample. QoL was strongly correlated with fatigue, anxiety, and depression. Conclusion The EORTC QLQ-C30 is a suitable instrument for measuring QoL in Ethiopia. The detriments in QoL in the Ethiopian patients indicate specific cancer care needs for the patients in a developing country.

AbstractPalliative care aims at improving the patient’s quality of life. The assessment of this quality of life (QoL) is crucial for the evaluation of palliative care outcome. Many patients require hospital admissions for symptom control during their cancer journey and most of them die in hospitals, although they would like to stay at home until the end of their lives. In 1986, the European Organization for Research and Treatment (EORTC) initiated a research programme to develop an integrated, modular approach for evaluating the quality of life of patients participating in international clinical trials. This questionnaire measures cancer patients’ physical, psychological and social functions and was used in a wide range of clinical cancer trials with large numbers of research groups and also in various other non-trial studies. The aim of this study was to evaluate the psychometric properties, especially the reliability, validity and applicability of the EORTC QLQ-C30 in a German sample of terminally ill cancer patients receiving palliative care in different settings. The questionnaire was well accepted in the present patient population. Scale reliability was good (pre-treatment 0.80) especially for the functional scale. The results support the reliability and validity of the QLQ-C30 (version 3.0) as a measure of the health-related quality of life in German cancer patients receiving palliative care treatment.

AbstractQuality of life (QoL) is an important outcome criterion in cancer research and practice. Multiple studies have been performed to test the short-term temporal stability (1 day–2 weeks) of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire EORTC QLQ-C30, but its stability over longer periods of time is largely unknown. The EORTC QLQ-C30 was administered at two time points between 3 and 12 months apart in six samples of cancer patients with varying characteristics (N between 298 and 923). Averaged across the six samples, the coefficients of temporal stability (intra-class correlation coefficients ICC) were between 0.31 and 0.59 for the single scales. The 2-item global health/QoL scale showed a mean coefficient of 0.44. When the stability coefficients were calculated separately for males and females and for younger vs. older patients, no systematic gender or age differences were found in the temporal stability of the QoL scales, though the stability was slightly higher in males (vs. females) and in older subgroups (vs. younger subgroups). It is nearly impossible to predict the course a cancer patients’ QoL will take over a several month period. Repeated measurements are necessary to track QoL developments.

Introdução: A qualidade de vida de pacientes oncológicos tem sido objeto de estudo em muitos trabalhos brasileiros. Contudo, apesar da alta prevalência de indivíduos submetidos a radioterapia, poucos estudos com ênfase nesse grupo de pacientes foram identificados. Objetivo: Avaliar a qualidade de vida e a prevalência de sintomas depressivos em pacientes com neoplasias malignas durante o tratamento radioterápico. Método: Estudo transversal quantitativo realizado com 153 pacientes oncológicos em vigência de tratamento radioterápico em um centro especializado em oncologia e radioterapia, localizado no Noroeste do Estado do Parana. Os dados foram coletados entre marco e setembro de 2018. O European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) e o Inventario de Depressão de Beck foram utilizados para avaliar a qualidade de vida e os sintomas depressivos, respectivamente. Resultados: Os domínios “qualidade de vida”, “função cognitiva” e “função social” foram os que menos se mostraram prejudicados na amostra estudada, enquanto “insônia”, “perda de apetite” e “dificuldades financeiras” destacaram-se entre os maiores preditores de baixa qualidade de vida. Ademais, contatou-se que 22% dos indivíduos avaliados apresentaram algum grau de transtorno de humor, sendo 11% diagnosticados com depressão. Conclusão: O declínio na qualidade de vida e a prevalência de sintomas depressivos em pacientes oncológicos, mesmo os em vigência de radioterapia, enaltecem a importância de intervenções precoces que visem a restabelecer a funcionalidade e o bem-estar.

Introdução: O câncer de mama pode alterar a qualidade de vida relacionada à saúde das pacientes. Objetivo: Compreender o impacto da quimioterapia para câncer de mama na qualidade de vida relacionada à saúde de pacientes. Método: Trata-se de uma revisão integrativa da literatura, compreendendo artigos publicados entre 2007 e 2019, disponíveis nas bases de dados PubMed, LILACS e SciELO. Analisaram-se 25 artigos na íntegra. Resultados: Os questionários mais frequentemente utilizados nos estudos foram o European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) e o módulo complementar European Organization for Research and Treatment of Cancer Breast Cancer-specific Quality of Life Questionnaire (EORTC QLQ-BR23). Em relação às alterações da qualidade de vida, a saúde global diminui durante a quimioterapia, mas pode melhorar após o término do tratamento. O aumento dos sintomas é relatado em diversos estudos e prejudicou a qualidade de vida relacionada à saúde das pacientes. Entretanto, os sintomas diminuem após o término da quimioterapia, exceto para algumas escalas. As escalas de imagem corporal, função sexual e funcionamento físico pioram ao longo do tratamento. A qualidade de vida mental/psicológica tem oscilações durante o tratamento, assim como a escala sobre as relações sociais. Conclusão: A qualidade de vida relacionada à saúde de mulheres com câncer de mama é afetada negativamente pelo tratamento quimioterápico, expressando maior impacto nas escalas de sintomas.

Purpose: To evaluate the effect of a standardized group psychosocial intervention on health-related quality of life (HrQOL) in women with metastatic breast cancer and to explore the effect of missing data in HrQOL analyses. Patients and Methods: Between 1993 and 1998, seven Canadian centers randomly assigned 235 eligible women to participate in a weekly, 90-minute, therapist-led support group that adhered to principles of supportive-expressive (SE) therapy or to a control arm (no SE). All women received educational material and any type of medical or psychosocial care deemed necessary. HrQOL data were prospectively collected using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) at baseline, 4, 8, and 12 months. The primary HrQOL analyses compared scores in the two study arms. Analyses were limited to women with appropriate baseline HrQOL information (n = 215). Results: Baseline EORTC QLQ-C30 scores were not different between the two study arms (all P > .05). Primary analysis of all subscales failed to show a significant influence of the intervention on HrQOL (all P > .05). There was a significant deterioration over time in several functional scales of the EORTC QLQ-C30: global (P = .03), physical (P = .0002), role (P = .01), and cognitive functioning (P = .04); and in symptom scales: dyspnea (P = .007), appetite loss (P = .04), and fatigue (P = .003); these changes were independent of randomization allocation. Results were similar in additional analyses of overall HrQOL using a variety of approaches to handling missing data. Conclusion: Supportive-expressive group therapy in patients with metastatic breast cancer does not appear to influence HrQOL, as measured by the EORTC QLQ-C30.
