Factors Associated with Health-Related Quality of Life Among Breast Cancer Survivors in Saudi Arabia: Cross-Sectional Study.

BACKGROUND: Assessment of health-related quality of life (HRQOL) is a major concern among breast cancer survivors. Little is known about HRQO and its determinants in Saudi women with breast cancer (BC). This study aimed to describe the HRQOL of Saudi women with breast cancer and the association between HRQO and sociodemographic and clinical variables. METHODS: This cross-sectional study involved 147 BC participants who completed the 36-item Short Form Health Survey (SF-36). Multivariable linear logistic regression analysis was conducted to determine factors associated with HRQOL. RESULTS: For the physical component scale, general health scored the highest (55.41±17.99) while, role physical function scored the lowest (48.61±22.51). The mean scores in the mental component were higher for social function (56.91±20.84), while the lowest score was observed for energy and vitality (49.62±20.84). Significant differences were observed in many SF-36 domains across the sociodemographic and clinical variables. Older age, having had a mastectomy as well as comorbid conditions, and receiving chemotherapy and hormonal therapy were associated with decreased HRQOL. However, being physically active, employed, and having more education were associated with higher HRQOL. CONCLUSION: HRQOL is generally poor among breast cancer survivors in Saudi Arabia, depending on a variety of factors. These findings highlight the need for routine QOL assessment. Furthermore, recognizing these predictors may play a key role in maximizing HRQOL for breast cancer participants.

Psychometric Properties and Factorial Analysis of the Arabic McGill-QoL Questionnaire in Breast Cancer.

Purpose: This study aimed to assess the psychometric properties of the Arabic McGill Quality of Life Questionnaire-Revised (MQOL-R) in breast cancer survivors. Patients and Methods: One-hundred-forty breast cancer survivors were recruited and completed the questionnaire. The construct validity was assessed using confirmatory factor analysis (CFA). MQOL-R scores were correlated with Global Health Status/QoL and functional subscales of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) for convergent validity. Reliability was estimated using Cronbach's alpha and intraclass correlation coefficients (ICC). Results: CFA reproduced a four-factor model (ie, physical, psychological, existential, and social) with good fit indices (comparative fitting index = 0.980; root mean square error of approximation = 0.091), with all items significantly loading on their respective subscales. The total MQOL-R scores were correlated with the global health status/QoL and functional subscales of the EORTC QLQ-C30 (r = -0.172, P < 0.01). Known-group validity was proven by different MQOL-R scores according to functional status (50.62 ± 6.35 vs 45.98 ± 7.19, P < 0.01). Reliability was supported by good internal consistency and high test-retest correlation coefficients for the Arabic MQOL-R and its subscales (ICC range, 0.83-0.95). Conclusion: The Arabic MQOL-R demonstrated adequate construct validity, factor structure, excellent test-retest reliability, and good internal consistency. This tool is valuable for assessing the quality of life in research and physical therapy rehabilitation settings among Arabic-speaking breast cancer survivors.

Measurement properties of the Arabic version of the pediatric functional assessment of chronic illness therapy-fatigue in children with cancer.

BACKGROUND: The pediatric Functional Assessment of Chronic Illness Therapy-Fatigue (PedsFACIT-F) measures fatigue in various clinical settings. OBJECTIVE: To verify the measurement properties of the Arabic version (PedsFACIT-F-Ar) in patients with cancer. METHODS: In this cross-sectional validation study, the PedsFACIT-F and the Pediatric Quality of Life Multidimensional Fatigue Scale (PedsQL-MFS) were administered to 114 participants (74 boys and 40 girls) aged 8-18. Exploratory factor analysis was used to test the structural validity of PedsFACIT-F-Ar. Its construct validity was investigated using the hypothesis testing method to predict a moderate correlation (rho ⩾ 0.4) with the PedsQL-MFS domains and the total score. Its reliability was also tested. RESULTS: The PedsFACIT-F-Ar is a two-factor model that explains 67.38% of the total variance. It is significantly correlated with PedsQL-MFS (rho > 0.84). It displayed excellent internal consistency (Cronbach's α= 0.93) and test-retest reliability (ICC2.1= 0.99; 95% CI: 0.96-0.99). Bland-Altman's analysis revealed the absence of a systematic error between the two test sessions. The standard error of measurement, minimal detectable change (MDC95), and MDC% were 0.92, 2.56 points, and 2.88%, respectively, with no floor or ceiling effects. CONCLUSIONS: The PedsFACIT-F-Ar demonstrated excellent psychometric properties. The findings suggest the clinical usefulness of this scale.

Psychometric performance of the Arabic versions of the Functional Assessment of Cancer Therapy-Breast plus Arm morbidity (FACT-B + 4) in patients with breast cancer related lymphedema: cross-sectional study.

BACKGROUND: Burden of breast cancer it continues to increase largely because of the aging and growth of the world population and assessment of quality of life is an important outcome measure to facilitate and improved care among breast cancer survivors, the aim of this study was to evaluate evidence of reliability, validity, and responsiveness of the Arabic version of the FACT-B + 4 questionnaire among participants with breast cancer related lymphedema (BCRL) in Saudi Arabia. METHODS: A prospective cross-sectional study, 51 participants with BCRL completed the Arabic version of FACT-B + 4. Internal consistency and test-retest-reliability were assessed using Cronbach's alpha, intraclass correlation-coefficient (ICC), and limits of agreement according to the Bland Altman method, respectively. The validation studies were carried-out by examining predefined hypotheses (n = 14) for both construct and Known-groups validity. To investigate the responsiveness, the Arabic version of FACT-B + 4 questionnaire was administrated preoperative and 4 weeks postoperatively among the participants with breast cancer (n = 34). RESULTS: The Cronbach alpha of the Arabic FACT-B + 4 total score was 0.90 and for the different subscales ranged from 0.74 to 0.89. Test-retest reliability for FACT-B + 4 total score and different subscales was found to be moderate to very strong (ICC 0.51-0.94). The Bland-Altman plot was adequate - 19.24 and 22.10 points. Measurement variability was acceptable for Arabic FACT-B + 4 and ARM subscale (standard error of measurement = 5.34, and 1.34). Moderate correlations (r = 0.42-0.62) were found between the subscale of the FACTB + 4 and the corresponding domains of SF-36. For known group validity, 72% (10 of 14) hypotheses on known group validity were accepted. CONCLUSION: FACT-B + 4 has adequate psychometric properties, thus making it useful for assessing QOL quality of life in Arabic speaking women with BCRL.

Lymphedema rehabilitation: Provision and practice patterns among service providers: National survey.

Information on the current practices and quantification of lymphedema service may be beneficial to promote and improve the current health care system. Therefore, this study aimed to describe the characteristics of lymphedema practitioners, and lymphedema patients' profiles, and provide a comprehensive picture of lymphedema service provision in Saudi Arabia. A cross-sectional study design used an online survey to gather data. The survey included information about demographic and professional characteristics of lymphedema practitioners, lymphedema profiles, questions on the services provided, and perceived barriers in providing services. Eighteen lymphedema practitioners (38%) responded to the survey. Most of the respondents were physical therapists (94%), who had completed 135 hours of basic training course, and were certified as lymphedema therapists (89%). Most of these practitioners were in Riyadh (58%), Jeddah (25%), and Dammam (17%). About 75% of patients seen by practitioners had secondary lymphedema, predominately breast cancer-related lymphedema (47%). The average number of lymphedema practitioners per service is three. The perceived barriers reported included an inadequate number of certified therapists (100%), difficulties with transportation and lack of financial support (each; 72%), and limited space for lymphedema practice/management (89%). The results suggest lymphedema practitioners provide reasonable services for lymphedema patients; however, services are still limited and needs are unmet. Therefore, more staffing is required to promote awareness of the condition and related services, to develop and implement appropriate educational strategies, and improve geographical and multidisciplinary coordination of the services in Saudi Arabia.

Low-Intensity Resistance Training and Compression Garment in the Management of Breast Cancer-Related Lymphedema: Single-Blinded Randomized Controlled Trial.

There is limited evidence regarding the combined effect of exercise and compression garment on breast cancer-related lymphedema (BCRL). Therefore, we investigate the effect of low-intensity resistance training alone or in combination with a compression garment on lymphedema volume, self-reported lymphedema symptoms, and shoulder mobility and function. A total of 60 women with unilateral BCRL were randomly assigned to low-intensity resistance exercises (Rex group, n = 30) or exercises and compression garment (Rex-Com-group, n = 30). Both groups take part in exercises program consisted of 10-12 repetitions at 50 to 60% of one repetition maximum (IRM), three times weekly, for 8 weeks. The primary outcome was lymphedema volume determined by percentage reduction of excess limb volume (ELV). Secondary outcomes were lymphedema symptoms (pain, heaviness, and tightness) and shoulder mobility and function using the disabilities of the arm, shoulder, and hand (DASH) questionnaire. All measurements were standardized and performed before (week 0, W0), after the intervention (week 8, W8), and at follow-up (week 12, W12). A significant reduction in percentage of ELV (p < 0.01), pain severity (p < 0.05), a sensation of heaviness (p < 0.05) and tightness (p < 0.001), and improvement in shoulder range of motion (p < 0.05) and function on DASH scores (p < 0.05) were observed at W8 and W12 in both groups. However, no between-group differences were observed over time. These findings suggest that low-intensity resistance training, irrespective of garment use, can effectively reduce limb volume and lymphedema symptoms, and increase shoulder mobility and function.
