ABSTRACT

BACKGROUND: Patient-reported physical function (PF) is a key endpoint in cancer clinical trials. Using complex statistical methods, common metrics have been developed to compare scores from different patient-reported outcome (PRO) measures, but such methods do not account for possible differences in questionnaire content. Therefore, the aim of our study was a content comparison of frequently used PRO measures for PF in cancer patients. METHODS: Relying on the framework of the International Classification of Functioning, Disability and Health (ICF) we categorized the item content of the physical domains of the following measures: EORTC CAT Core, EORTC QLQ-C30, SF-36, PROMIS Cancer Item Bank for Physical Function, PROMIS Short Form for Physical Function 20a, and the FACT-G. Item content was linked to ICF categories by two independent reviewers. RESULTS: The 118 items investigated were assigned to 3 components ('d - Activities and Participation', 'b - Body Functions', and 'e - Environmental Factors') and 11 first-level ICF categories. All PF items of the EORTC measures but one were assigned to the first-level ICF categories 'd4 - Mobility' and 'd5 - Self-care', all within the component 'd - Activities and Participation'. The SF-36 additionally included item content related to 'd9 - Community, social and civic life' and the PROMIS Short Form for Physical Function 20a also included content related to 'd6 - domestic life'. The PROMIS Cancer Item Bank (v1.1) covered, in addition, two first-level categories within the component 'b - Body Functions'. The FACT-G Physical Well-being scale was found to be the most diverse scale with item content partly not covered by the ICF framework. DISCUSSION: Our results provide information about conceptual differences between common PRO measures for the assessment of PF in cancer patients. Our results complement quantitative information on psychometric characteristics of these measures and provide a better understanding of the possibilities of establishing common metrics.

ABSTRACT

BACKGROUND: The European Organization for Research and Treatment of Cancer (EORTC) QLQ-BR23 was one of the first disease-specific questionnaires developed in 1996 to assess quality of life (QoL) in patients with breast cancer (BC). However, since 1996 major changes in BC treatment have occurred, requiring an update of the EORTC BC module. This study presents the results of the phase I-III update of the QLQ-BR23 questionnaire. PATIENTS AND METHODS: The update of the EORTC QLQ-BR23 module followed standard EORTC guidelines. A systematic literature review revealed 83 potential relevant QoL issues during phases I and II. After shortening the issues list and following interviews with patients and health care providers, 15 relevant issues were transformed into 27 items. The preliminary module was pretested in an international, multicentre phase III study to identify and solve potential problems with wording comprehensibility and acceptability of the items. Descriptive statistics are provided. Analyses were qualitative and quantitative. We provide a psychometric structure of the items. RESULTS: The phase I and II results indicated the need to supplement the original QLQ-BR23 with additional items related to newer therapeutic options. The phase III study recruited a total of 250 patients (from 12 countries). The final updated phase III module contains a total of 45 items: 23 items from the QLQ-BR23 and 22 new items. The new items contain two multi-item scales: a target symptom scale and a satisfaction scale. The target symptom scale can be divided into three subscales: endocrine therapy, endocrine sexual and skin/mucosa scale. CONCLUSION: Our work has led to the development of a new EORTC QLQ-BR45 module that provides a more accurate and comprehensive assessment of the impact of new and scalable treatments on patients' QoL. The final version of the EORTC QLQ-BR45 is currently available for use in clinical practice. The final phase IV study is underway to confirm psychometric properties of the module.

ABSTRACT

BACKGROUND: Communication between health care provider and patients in oncology presents challenges. Communication skills training have been frequently developed to address those. Given the complexity of communication training, the choice of outcomes and outcome measures to assess its effectiveness is important. The aim of this paper is to 1) perform a systematic review on outcomes and outcome measures used in evaluations of communication training, 2) discuss specific challenges and 3) provide recommendations for the selection of outcomes in future studies. METHODS: To identify studies and reviews reporting on the evaluation of communication training for health care professionals in oncology, we searched seven databases (Ovid MEDLINE, CENTRAL, CINAHL, EMBASE, PsychINFO, PsychARTICLES and Web of Science). We extracted outcomes assessed and the respective assessment methods. We held a two-day workshop with experts (n = 16) in communication theory, development and evaluation of generic or cancer-specific communication training and/or outcome measure development to identify and address challenges in the evaluation of communication training in oncology. After the workshop, participants contributed to the development of recommendations addressing those challenges. RESULTS: Out of 2181 references, we included 96 publications (33 RCTs, 2 RCT protocols, 4 controlled trials, 36 uncontrolled studies, 21 reviews) in the review. Most frequently used outcomes were participants' training evaluation, their communication confidence, observed communication skills and patients' overall satisfaction and anxiety. Outcomes were assessed using questionnaires for participants (57.3%), patients (36.0%) and observations of real (34.7%) and simulated (30.7%) patient encounters. Outcomes and outcome measures varied widely across studies. Experts agreed that outcomes need to be precisely defined and linked with explicit learning objectives of the training. Furthermore, outcomes should be assessed as broadly as possible on different levels (health care professional, patient and interaction level). CONCLUSIONS: Measuring the effects of training programmes aimed at improving health care professionals' communication skills presents considerable challenges. Outcomes as well as outcome measures differ widely across studies. We recommended to link outcome assessment to specific learning objectives and to assess outcomes as broadly as possible.

ABSTRACT

PURPOSE: In this paper we study the quality of life (QoL) of elderly breast cancer patients receiving endocrine treatment (ET). More QoL data on elderly patients treated with ET are needed. Our aims are to study QoL in early-stage breast cancer patients throughout the treatment period and compare the QoL of ET groups. METHODS: 148 patients > 65 years who began ET with either tamoxifen or aromatase inhibitor (AI) completed the EORTC QLQ-C30 and QLQ-BR23 and the Interview for Deterioration in Daily Living Activities in Dementia (IDDD) questionnaires three times over 3 years of ET. Linear mixed-effect models were used to evaluate longitudinal QoL changes. ET group comparisons were conducted after 3 years of treatment via ANCOVA adjusted by basal QoL. RESULTS: QoL scores were high (> 80/100 points) in most QoL areas, with moderate limitations (> 30) in sexual functioning and enjoyment and in future perspective. After 3 years of ET, four QoL areas improved (< 6 points) compared to baseline and 3-month assessments. Hot flushes worsened (8 points) at the 3-month assessment but by 3 years had recovered. AI patients showed more hot flushes, pain and diarrhea and less sexual enjoyment than tamoxifen patients after 3 years of ET (differences 3-12 points). CONCLUSIONS: Results indicate that elderly early-stage breast cancer patients adapted well to their disease and ET treatment over the 3 years. Few QoL differences were observed between ET groups.

ABSTRACT

Advances in cancer care delivery require revision and further development of questionnaires assessing patients' perceived quality of care. This study pre-tested the revised EORTC satisfaction with cancer care core questionnaire applicable in both the cancer inpatient and outpatient settings, and its new, outpatient-specific complementary module. The process of revision, development of the extended application, and pre-testing of these questionnaires was based on phases I to III of the "EORTC Quality of Life Group Module Development Guidelines." In phase III, patients in 11 countries in four European regions, South America and Asia completed provisional versions of the questionnaires. Fifty-seven relevant issues selected from literature reviews and input from experts were operationalized into provisional items, and subsequently translated into ten languages. Assessment of understanding, acceptability, redundancy and relevance by patients (n = 151) from oncology inpatient wards, and outpatient chemotherapy, radiotherapy and consultation settings, led to retention of, deletion of and merging of 40, 14 and 6 items respectively. Cronbach's alpha coefficients for hypothesized questionnaire scales were above 0.80. Our results provide preliminary support for the 33-item EORTC Satisfaction with cancer care core questionnaire and the 7-item complementary module specific for the outpatient care setting. A large scale phase IV cross-cultural psychometric study is now underway.

ABSTRACT

BACKGROUND: The European Organization for Research and Treatment of Cancer (EORTC) QLQ-LC13 was the first module to be used in conjunction with the core questionnaire, the QLQ-C30. Since the publication of the LC13 in 1994, major advances have occurred in the treatment of lung cancer. Given this, an update of the EORTC QLQ-LC13 was undertaken. METHODS: The study followed phases I to III of the EORTC Module Development Guidelines. Phase I generated relevant quality-of-life issues using a mix of sources including the involvement of 108 lung cancer patients. Phase II transformed issues into questionnaire items. In an international multicenter study (phase III), patients completed both the EORTC QLQ-C30 and the 48-item provisional lung cancer module generated in phases I and II. Patients rated each of the items regarding relevance, comprehensibility, and acceptance. Patient ratings were assessed against a set of prespecified statistical criteria. Descriptive statistics and basic psychometric analyses were carried out. RESULTS: The phase III study enrolled 200 patients with histologically confirmed lung cancer from 12 centers in nine countries (Cyprus, Germany, Italy, Israel, Spain, Norway, Poland, Taiwan, and the UK). Mean age was 64 years (39 - 91), 59% of the patients were male, 82% had non-small-cell lung cancer, and 56% were treated with palliative intent. Twenty-nine of the 48 questions met the criteria for inclusion. CONCLUSIONS: The resulting module with 29 questions, thus currently named EORTC QLQ-LC29, retained 12 of the 13 original items, supplemented with 17 items that primarily assess treatment side-effects of traditional and newer therapies.

ABSTRACT

The EORTC Quality of Life Group has just completed the final phase (field-testing and validation) of an international project to develop a stand-alone measure of spiritual well-being (SWB) for palliative cancer patients. Participants (n = 451)-from 14 countries on four continents; 54% female; 188 Christian; 50 Muslim; 156 with no religion-completed a provisional 36-item measure of SWB plus the EORTC QLQ-C15-PAL (PAL), then took part in a structured debriefing interview. All items showed good score distribution across response categories. We assessed scale structure using principal component analysis and Rasch analysis, and explored construct validity, and convergent/divergent validity with the PAL. Twenty-two items in four scoring scales (Relationship with Self, Relationships with Others, Relationship with Someone or Something Greater, and Existential) explained 53% of the variance. The measure also includes a global SWB item and nine other items. Scores on the PAL global quality-of-life item and Emotional Functioning scale weakly-moderately correlated with scores on the global SWB item and two of the four SWB scales. This new validated 32-item SWB measure addresses a distinct aspect of quality-of-life, and is now available for use in research and clinical practice, with a role as both a measurement and an intervention tool.

ABSTRACT

BACKGROUND: The objective of the study is to determine the correlations among the variables of dose and the sphincter function (SF) in patients with locally advanced rectal cancer treated with preoperative capecitabine/radiotherapy followed by low anterior resection (LAR) + TME. METHODS: We retrospectively reviewed 92 consecutive patients with LARC treated at our center with LAR from 2006 and more than 2 years free from disease. We re-contoured the anal sphincters (AS) of patients with the help of the radiologist. SF was assessed with the Wexner scale (0-20 points, being punctuation inversely proportional to annal sphincter functionality). All questionnaires were filled out between January 2010 and December 2012. Dosimetric parameters that have been studied include V 20, V 30, V 40, V 50, mean dose (D mean), minimum dose (D min), D 90 (dose received by 90% of the sphincter) and D 98. STATISTICAL ANALYSIS: The correlations among the variables of dose and SF were studied by the Spearman correlation coefficient. Differences in SF relating to maximum doses to the sphincter were assessed by the Mann-Whitney test. RESULTS: Mean Wexner score was 5.5 points higher in those patients with V 20 > 0 compared to those for which V 20 = 0 (p = 0.008). In a multivariate regression model, results suggest that the effect of V 20 on poor anal sphincter control is independent of the effect of distance, with an adjusted OR of 3.42. CONCLUSIONS: In order to improve the SF in rectal cancer treated with preoperative radiotherapy/capecitabine followed by conservative surgery, the maximum radiation dose to the AS should be limited, when possible, to <20 Gy.

ABSTRACT

BACKGROUND: Older people represent the majority of cancer patients but their specific needs are often ignored in the development of health-related quality of life (HRQOL) instruments. The European Organisation for Research and Treatment of Cancer (EORTC) QLQ-ELD15 was developed to supplement the EORTC's core questionnaire, the QLQ-C30, for measuring HRQOL in patients aged >70 years in oncology studies. METHODS: Patients (n=518) from 10 countries completed the QLQ-C30, QLQ-ELD15 and a debriefing interview. Eighty two clinically stable patients repeated the questionnaires 1 week later (test-retest analysis) and 107 others, with an expected change in clinical status, repeated the questionnaires 3 months later (response to change analysis, RCA). RESULTS: Information from the debriefing interview, factor analysis and item response theory analysis resulted in the removal of one item (QLQ-ELD15QLQ-ELD14) and revision of the proposed scale structure to five scales (mobility, worries about others, future worries, maintaining purpose and illness burden) and two single items (joint stiffness and family support). Convergent validity was good. In known-group comparisons, the QLQ-ELD14 differentiated between patients with different disease stage, treatment intention, number of comorbidities, performance status and geriatric screening scores. Test-retest and RCA analyses were equivocal. CONCLUSION: The QLQ-ELD14 is a validated HRQOL questionnaire for cancer patients aged 70 years. Changes in elderly patients' self-reported HRQOL may be related to both cancer evolution and non-clinical events.

ABSTRACT

Visceral regeneration in sea cucumbers has been studied since early last century; however, it is only within the last 15 years that real progress has been made in understanding the cellular and molecular events involved. In the present review, we bring together these recent studies, providing readers with basic information on the anatomy and histology of the normal gut and detailing the changes in tissue organization and gene expression that occur during the regenerative process. We discuss the nature and possible sources of cells involved in the formation of the intestinal regenerate as well as the role of cell death and proliferation in this process. In addition, we compare gut formation during regeneration and during embryogenesis. Finally, we describe the molecular studies that have helped advance regenerative studies in holothurians and integrate the gene expression information with data on cellular events. Studies on visceral regeneration in these echinoderms provide a unique view that complements regeneration studies in other animal phyla, which are mainly focused on whole-animal regeneration or appendage regeneration.

ABSTRACT

INTRODUCTION: The EORTC QLQ-INFO25 evaluates the information received by cancer patients. This study assesses the psychometric properties of the QLQ-INFO25 when applied to a sample of Spanish patients. MATERIALS AND METHODS: A total of 169 patients with different cancers and stages of disease completed the EORTC QLQINFO25, the EORTC QLQ-C30 and the information scales of the inpatient satisfaction module EORTC IN-PATSAT32 on two occasions during the patients' treatment and follow- up period. Psychometric evaluation of the structure, reliability, validity and responsiveness to changes was conducted. Patient acceptability was assessed with a debriefing questionnaire. RESULTS: Multi-trait scaling confirmed the 4 multi-item scales (information about disease, medical tests, treatment and other services) and eight single items. All items met the standards for convergent validity and all except one met the standards of item discriminant validity. Internal consistency for all scales (α>0.70) and the whole questionnaire (α>0.90) was adequate in the three measurements, except information about the disease (0.67) and other services (0.68) in the first measurement, as was test-retest reliability (intraclass correlations >0.70). Correlations with related areas of IN-PATSAT32 (r>0.40) supported convergent validity. Divergent validity was confirmed through low correlations with EORTC QLQ-C30 scales (r<0.30). The EORTC QLQ-INFO-25 discriminated among groups based on gender, age, education, levels of anxiety and depression, treatment line, wish for information and satisfaction. One scale and an item showed changes over time. CONCLUSIONS: The EORTC QLQ-INFO 25 is a reliable and valid instrument when applied to a sample of Spanish cancer patients. These results are in line with those of the EORTC validation study (AU)

ABSTRACT

Quality of life assessment is one of the key elements of the care that is offered to cancer patients. The aim of this work is to present the research line on quality of life that has been carried out since 1992 in the Oncology Departments of the Hospital de Navarra. These departments actively collaborate with the European Organisation of Research and Treatment of Cancer - EORTC - Quality of Life Group in creating questionnaires and also in other projects of this group. Our institution has coordinated the development process of the EORTC information module. Different EORTC questionnaires have been validated for use in our country. Quality of life studies have been carried out in the main tumour sites and in other areas, such as patients' satisfaction with care. This research line has a direct benefit on the attention that patients receive.

ABSTRACT

INTRODUCTION: The EORTC Quality of Life (QL) Group has developed a questionnaire -the EORTC QLQ-CR29- for evaluating QL in colorectal cancer. The aim of this study is to assess the psychometric properties of the EORTC QLQCR29 when applied to a sample of Spanish patients. MATERIALS AND METHODS: Eighty-four locally advanced rectal cancer patients in the treatment follow-up period after receiving surgery and neoadjuvant chemoradiotherapy were included in the study. Seventy subjects also had adjuvant chemotherapy. Patients completed both the EORTC QLQC30 and the QLQ-CR29 once. The psychometric evaluation of the questionnaire's structure, reliability, and convergent, divergent and known-groups validity was performed. RESULTS: Multitrait scaling analysis showed that three of the multi-item scales met the standards of convergent and discriminant validity. These same scales reached the 0.7 Cronbach's coefficient criterion or were close to it. In both analyses exceptions were observed in the blood and mucus in stool scale. Correlations between the scales of the QLQC30 and the module were low (r<0.02) in most cases. A few areas with more related content had higher correlations (r<0.05). Group comparison analyses showed differences in QL between groups of patients based on age, comorbidity, performance status, receipt of adjuvant chemotherapy and surgery modality. CONCLUSIONS: The EORTC QLQ-CR29 is a reliable and valid instrument when applied to a sample of Spanish rectal cancer patients. These results are in line with those of the EORTC validation study (AU)

ABSTRACT

This international study aimed to test the measurement properties of the updated European Organisation for Research and Treatment of Cancer (EORTC) questionnaire module for colorectal cancer, the QLQ-CR29. The QLQ-CR29 was administered with the QLQ-C30, core questionnaire, to 351 patients from seven countries. Questionnaire scaling and reliability were established and clinical and psychometric validity examined. Patient acceptability and understanding were assessed with a debriefing questionnaire. Multi-trait scaling analyses and face validity refined the module to four scales assessing urinary frequency, faecal seepage, stool consistency and body image and single items assessing other common problems following treatment for colorectal cancer. Scales distinguished between clinically distinct groups of patients and did not correlate with QLQ-C30 scales, demonstrating construct validity. The QLQ-CR29 scores were reproducible over time in stable health. The EORTC QLQ-CR29 demonstrates sufficient validity and reliability to support its use to supplement the EORTC QLQ-C30 to assess patient-reported outcomes during treatment for colorectal cancer in clinical trials and other settings.
