Unraveling Desmoid-Type Fibromatosis-Specific Health-Related Quality of Life: Who Is at Risk for Poor Outcomes

Simple Summary

Desmoid-type fibromatosis (DTF) is an uncommon, non-metastasising soft-tissue tumour. Patients can experience a wide variety of disease-specific issues related to the unpredictable clinical course and aggressiveness of DTF, negatively impacting their health-related quality of life (HRQoL). Little is known about which DTF patients are particularly affected by an impaired HRQoL. In the current study, HRQoL was evaluated among different groups of DTF patients, using the EORTC QLQ-C30 and the DTF-QoL, a DTF-specific HRQoL questionnaire. Age, sex, presence of comorbidities, and type of treatment were found to be most strongly associated with DTF-specific HRQoL outcomes. In general, socio-demographic factors had the greatest impact on generic HRQoL, whereas the influence of clinical factors was mainly seen on the DTF-QoL, underlining the importance of a disease-specific questionnaire. Knowledge of the differences in DTF-specific HRQoL between subgroups can be used to individualize the HRQoL-measurement strategy for research and clinical practice.

Abstract

Desmoid-type fibromatosis (DTF) is a rare, soft-tissue tumour. These tumours do not metastasize, but their local aggressive tumour growth and unpredictable behaviour can have a significant impact on health-related quality of life (HRQoL). Little is known about which DTF patients are particularly affected by an impaired HRQoL. The objectives of this study were to assess HRQoL among different groups of DTF patients and to investigate which socio-demographic and clinical characteristics were associated with DTF-specific HRQoL. A cross-sectional study was conducted among DTF patients from the United Kingdom and the Netherlands. HRQoL was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), accompanied by the DTF-QoL to assess DTF-specific HRQoL. The scores were compared amongst subgroups, based on the socio-demographic and clinical characteristics of DTF patients. Multiple linear regression analyses with a backward elimination were conducted to identify the factors associated with DTF-specific HRQoL. A total of 235 DTF patients completed the questionnaires. Female patients, patients with more than two comorbidities, or patients who received treatment other than only active surveillance (AS) or surgery scored significantly worse on the subscales of both the EORTC QLQ-C30 and DTF-QoL. Patients that were ≥ 40 years scored significantly worse on the physical functioning scale of the EORTC QLQ-C30, while younger patients (18–39 years) scored significantly worse on several DTF-QoL subscales. Differences in the DTF-QoL subscales were found for tumour location, time since diagnosis and the presence of recurrent disease. Furthermore, treatments other than AS or surgery only, female sex, younger age and the presence of comorbidities were most frequently associated with worse scores on the DTF-QoL subscales. This study showed that (DTF-specific) HRQoL differs between groups of DTF patients. Awareness of these HRQoL differences could help to provide better, personalised care that is tailored to the needs of a specific subgroup.

The Evaluation of Health-Related Quality of Life Issues Experienced by Patients with Desmoid-Type Fibromatosis (The QUALIFIED Study)-A Protocol for an International Cohort Study

Sporadic desmoid-type fibromatosis (DTF) is a rare soft tissue tumour with an unpredictable clinical course. These tumours are incapable of metastasising, but their local aggressive tumour growth and tendency to recur locally can result in a substantial symptom burden. Measuring the impact of DTF on health-related quality of life (HRQoL) can be challenging due to the variable clinical presentation of the disease. Therefore, a HRQoL instrument assessing DTF-specific issues is needed. The QUALIFIED study aims to (1) pre-test a previously developed DTF-specific HRQoL tool (the DTF-QoL); (2) evaluate prevalence of HRQoL issues in adult DTF patients; and (3) identify subgroups at risk of impaired HRQoL. This study (NCT04289077) is an international, multicentre, cross-sectional, observational cohort study. Patients ≥ 18 years with sporadic DTF from the Netherlands and the United Kingdom will be invited to complete a set of questionnaires specifically composed for this patient group. Questionnaires will be completed using PROFILES (Patient Reported Outcomes Following Initial treatment and Long-term Evaluation of Survivorship). Analyses will include testing the psychometric properties of the DTF-QoL and evaluating the prevalence of HRQoL issues using the DTF-QoL, EORTC QOL-C30 and EQ-5D-5L, among other questionnaires. This study will provide insight into HRQoL issues experienced by patients with DTF. Awareness of these issues and the implementation of the DTF-QoL in research and clinical practice can help to improve overall HRQoL and to provide personalised care.

Impact of Pharmaceutical Care Interventions on Health-Related Quality-of-Life Outcomes: A Systematic Review and Meta-analysis

OBJECTIVE

To evaluate the impact of pharmaceutical care (PC) interventions on health-related quality of life (HRQoL) and determine sensitivity of HRQoL measures to PC services.

DATA SOURCES

MEDLINE, EMBASE, International Pharmaceutical Abstracts, PubMed, Global Health, PsychINFO, CINAHL, and Web of Science (January 2005 to September 2015) were searched.

STUDY SELECTION AND DATA EXTRACTION

Original English-language articles were included if PC impact on HRQoL was evaluated and reported using validated HRQoL measures.

DATA SYNTHESIS

A total of 31 randomized controlled trials, 9 nonrandomized studies with comparison groups, and 8 before-after studies were included. PC interventions resulted in significant improvement in 1 domain and ≥3 domains of HRQoL measures in 66.7% and 27.1% of the studies, respectively. There was a significant improvement in at least 1 domain in 18 of 32 studies using generic and 16 of 21 studies using disease-specific measures. When the Short Form 36 Items Health Survey (SF-36) measure was used, PC interventions had a moderate impact on social functioning (standardized mean difference [SMD] = 0.59; 95% CI = 0.14, 1.04), general health (SMD = 0.36; 95% CI = 0.12, 0.59), and physical functioning (SMD = 0.30; 95% CI = 0.11, 0.48). The pooled data on heart failure-specific (SMD = -0.17; 95% CI = -0.43, 0.09), asthma-specific (SMD = 0.17; 95% CI = -0.03, 0.36), and chronic obstructive pulmonary disease-specific (SMD = -0.09; 95% CI = -0.37, 0.19) measures indicated no significant impact of PC on HRQoL.

CONCLUSIONS

PC interventions can significantly improve at least 1 domain of HRQoL. Existing measures may have minimal to moderate sensitivity to PC interventions, with evidence pointing more toward social functioning, general health, and physical functioning of the SF-36 measure. However, evidence generated from current non-PC-specific HRQoL measures is insufficient to judge the impact of PC interventions on HRQoL. The development of a suitable HRQoL measure for PC interventions may help generate better evidence for the contribution of pharmacist services to improving HRQoL.

Psychometric comparisons of four disease-specific health-related quality of life measures for stroke survivors

OBJECTIVE

To examine psychometric properties of four stroke-specific health-related quality of life (HRQoL) measures, including original Stroke-Specific Quality of Life Scale (12-domain SSQoL), modified 8-domain SSQoL, Stroke Impact Scale (SIS 3.0), and modified SIS-16 focused on physical domains.

DESIGN AND SETTING

Prospective repeated measures study conducted in rehabilitation and wards in hospitals.

SUBJECTS

Study cohort was recruited with 263 patients in the first administration and 121 in the second administration, an average of two weeks later. To investigate discriminant validity, the same number of patients (i.e., 52) was grouped for each of 3 levels of stroke severity.

MAIN MEASURES

Outcome measures, including National Institutes of Health Stroke Scale, Mini-Mental State Examination, and Barthel Index. Patients completed HRQoL self-reports.

RESULTS

Domains of four measures showed (1) good reliability, except 12-domainSSQoL family roles (Cronbach's α = 0.68) and personality domains (Cronbach's α = 0.65) and SIS 3.0 social participation (ICC=0.67) domain; (2) acceptable precision, except 12-domain SSQoL family role domain and SIS 3.0 social participation domain; (3) good convergent validity, except 12-domain SSQoL/8-domain SSQoL vision domain (r = 0.19), (4) good discriminant validity, except 12-domain SSQoL and 8-domain SSQoL thinking domains (P = 0.365); and (5) acceptable floor effects and strong ceiling effects. The 12-domain SSQoL and 8-domain SSQoL met scaling assumptions better than SIS 3.0 and SIS-16.

CONCLUSIONS

Four measures showed acceptable psychometric properties with some domains slightly less satisfactory. Overall, use of 8-domain SSQoL and SIS 3.0 are feasible for clinical practice to monitor HRQoL of stroke survivors.
