Cross-Cultural Adaptation of the Functional Assessment of Cancer Therapy-Breast (FACT-B) in Malaysian Breast Cancer Survivors

The EORTC QLQ breast modules and the FACT-B for assessing quality of life in breast cancer patients - an updated literature review

PURPOSE OF REVIEW

Two commonly used quality of life questionnaires in breast cancer are EORTC QLQ-BR23, the FACT-B, and the extended FACT-B + 4. More recently, the EORTC EORTC QLQ-BR42 was developed. This systematic review compares the various versions of the EORTC QLQ and FACT tools for breast cancer in terms of their content, validity, and psychometric properties.

RECENT FINDINGS

Thirty-six studies met the inclusion criteria. All questionnaires have been proven to be valid, reliable and responsive. The provisional EORTC QLQ-BR45 transitioned to the EORTC QLQ-BR42 in Phase IV of its development, which encompasses the side effects associated with the latest breast cancer treatments. Both the EORTC and FACT measures assess physical and mental dimensions of quality of life, with the EORTC measure placing relatively more emphasis on physical content and FACT placing relatively more emphasis on mental (social and emotional) content. The four additional items in the FACT-B + 4 were developed to address arm lymphoedema following axillary surgery.

SUMMARY

The development and uptake of quality of life tools are essential in the evaluation of breast cancer treatments. The EORTC QLQ-BR42 and FACT-B are both valid, reliable, and responsive QoL questionnaires.

Evaluating the effect of upper-body morbidity on quality of life following primary breast cancer treatment: a systematic review and meta-analysis

PURPOSE

Improvements in breast cancer management continue to increase survival and life expectancy after treatment. Yet the adverse effects of treatment may persist long term, threatening physical, psychological, and social wellbeing, leading to impaired quality of life (QOL). Upper-body morbidity (UBM) such as pain, lymphoedema, restricted shoulder range of motion (ROM), and impaired function are widely reported after breast cancer treatment, but evidence demonstrating its impact on QOL is inconsistent. Therefore, the aim of the study was to conduct a systematic review and meta-analysis evaluating the effect of UBM on QOL following primary breast cancer treatment.

METHODS

The study was prospectively registered on PROSPERO (CRD42020203445). CINAHL, Embase, Emcare, PsycInfo, PubMed/Medline, and SPORTDiscus databases were searched for studies reporting QOL in individuals with and without UBM following primary breast cancer treatment. Primary analysis determined the standardised mean difference (SMD) in physical, psychological, and social wellbeing scores between UBM + /UBM - groups. Secondary analyses identified differences in QOL scores between groups, according to questionnaire.

RESULTS

Fifty-eight studies were included, with 39 conducive to meta-analysis. Types of UBM included pain, lymphoedema, restricted shoulder ROM, impaired upper-body function, and upper-body symptoms. UBM + groups reported poorer physical (SMD =  - 0.99; 95%CI =  - 1.26, - 0.71; p < 0.00001), psychological (SMD =  - 0.43; 95%CI =  - 0.60, - 0.27; p < 0.00001), and social wellbeing (SMD =  - 0.62; 95%CI =  - 0.83, - 0.40; p < 0.00001) than UBM - groups. Secondary analyses according to questionnaire showed that UBM + groups rated their QOL poorer or at equal to, UBM - groups across all domains.

CONCLUSIONS

Findings demonstrate the significant, negative impact of UBM on QOL, pervading physical, psychological, and social domains.

IMPLICATIONS FOR CANCER SURVIVORS

Efforts to assess and minimise the multidimensional impact of UBM are warranted to mitigate impaired QOL after breast cancer.

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.

Association of psychological distress with arm morbidity symptoms in breast cancer survivors: outcomes from the use of PHQ-9 and GAD-7 questionnaires

BACKGROUND

Although higher survival rates of breast cancer are achieved these days, breast cancer survivors are challenged with unwanted side effects from treatment or management that affect physical, functional, and psychological well-being of an individual. This study aimed to assess psychological distress status in Malaysian breast cancer survivors and factors that affected the condition.

METHODS

A cross-sectional study design was conducted on 162 breast cancer survivors from various breast cancer support groups in Malaysia. Psychological distress status was assessed based on depression and anxiety scores by applying the Malay version of Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder (GAD-7). Both instruments were self-administered along with a set of questionnaires comprising demographic, medical history, quality of life, and upper extremity function assessment. Outcomes from the PHQ-9 and GAD-7 were analyzed for severity level of psychological distress, and its association with relevant variables, arm morbidity symptoms, as well as the duration of cancer survivorship.

RESULTS

The univariate analysis showed that breast cancer survivors with arm morbidities after breast surgery had a higher score of depression (5.0 vs 4.0, p = 0.011) and anxiety (3.0 vs 1.0, p = 0.026) than those who did not. Besides that, receiving fewer post-rehabilitation treatments (p = 0.049) and having a family history of cancer (p = 0.022) were correlated with higher anxiety level. The level of depression and anxiety was inversely proportionate with quality of life and positively correlated with greater disability of the arm function (p < 0.05). Subsequent analysis showed that arm morbidity symptoms including difficulties in finding a t-shirt that fits and pain in the arm area after breast cancer surgery were positively associated with a higher level of psychological distress.

CONCLUSION

Our study demonstrated the association between psychological distress with arm morbidities in breast cancer survivors. Given that arm morbidities can affect not only physical, but psychological well-being, continuous or serial assessment on both aspects during cancer treatment may effectively help to address mental health issue experienced by this cancer population.

[Validity and reliability of DASH questionnaire in women who suffer from lymphedema as a side effect of a breast cancer treatment]

INTRODUCTION

DASH questionnaire was designed to assess upper limb function in musculoskeletal pathologies. The aim of this manuscript is to study the reliability and validity of this questionnaire, to determine if is adequate to use in women with lymphedema due to breast cancer treatment.

METHODS

Prospective study in 65 women with lymphedema due to breast cancer treatment was done, in which the reliability of DASH score with internal consistency (Cronbach's alpha) and test-retest reproducibility 15 days' interval (interclass correlation coefficient) and validity by correlation with SF-36v2 and FACT-B+4 (r or Kendall's τ b) scores was investigated.

RESULTS

The internal consistency and the test-retest were Cronbach's alpha 0.969 and interclass correlation coefficient 0.861, respectively. There was correlation between the DASH score with the SF-36v2 score, mainly in the areas of physical function, body pain and physical role (r 0.800, 0.738, and 0.682, respectively; p<0.001), and lowest with the emotional and social wellbeing. The DASH score had correlation with FACT-B+4 (0.836; p<0.001) and the subscales the upper limb score (r=0.816; p<0.001), and there was no correlation with the social/familiar subscale (r=0.193; p=0.216).

CONCLUSION

The DASH questionnaire is a reliable and valid tool to assess upper limb functionality in Spanish women with breast cancer related lymphedema.

Evaluation of Circulating MicroRNAs and Adipokines in Breast Cancer Survivors with Arm Lymphedema

Breast cancer-related lymphedema (BCRL) is a form of secondary lymphedema that is characterized by abnormal swelling of one or both arms due to the accumulation of lymph fluid in the interstitial tissue spaces, resulting from obstruction of the lymphatic vessels due to surgery insults, radiotherapy, or chemotherapy. Due to the multifactorial nature of this condition, the pathogenesis of secondary lymphedema remains unclear and the search for molecular factors associated with the condition is ongoing. This study aimed to identify serum microRNAs and adipokines associated with BCRL. Blood was collected from 113 breast cancer survivors and processed to obtain serum for small RNA-sequencing (BCRL vs. non-BCRL, n = 7 per group). MicroRNAs that were differentially expressed (fold change >1.5, p < 0.05) between lymphedema cases and those without lymphedema were further quantified in a validation cohort through quantitative reverse transcription PCR (BCRL n = 16, non-BCRL, n = 83). Leptin and adiponectin levels were measured in a combined cohort (BCRL n = 23, non-BCRL n = 90) using enzyme-linked immunosorbent assays. Two of the most significantly upregulated microRNAs, miR-199a-3p and miR-151a-3p, were strongly correlated with the onset of lymphedema and diabetes mellitus in the BCRL group. Leptin levels were higher in the BCRL cohort compared to the non-BCRL cohort (p < 0.05). A metabolic syndrome biomarker, the adiponectin/leptin ratio, was found to be lower in the BCRL group than in the non-BCRL group (median: 0.28 vs. 0.41, p < 0.05). Extensive studies on the mechanisms of the identified microRNAs and association of leptin with arm lymphedema may provide new insights on the potential biomarkers for lymphedema that should be followed up in a prospective cohort study.

Assessment of Potential Risk Factors and Skin Ultrasound Presentation Associated with Breast Cancer-Related Lymphedema in Long-Term Breast Cancer Survivors

Breast cancer has been reported to have the highest survival rate among various cancers. However, breast cancer survivors face several challenges following breast cancer treatment including breast cancer-related lymphedema (BCRL), sexual dysfunction, and psychological distress. This study aimed to investigate the potential risk factors of BCRL in long term breast cancer survivors. A total of 160 female breast cancer subjects were recruited on a voluntary basis and arm lymphedema was assessed through self-reporting of diagnosis, arm circumference measurement, and ultrasound examination. A total of 33/160 or 20.5% of the women developed BCRL with significantly higher scores for upper extremity disability (37.14 ± 18.90 vs. 20.08 ± 15.29, p < 0.001) and a lower score for quality of life (103.91 ± 21.80 vs. 115.49 ± 16.80, p = 0.009) as compared to non-lymphedema cases. Univariate analysis revealed that multiple surgeries (OR = 5.70, 95% CI: 1.21–26.8, p < 0.001), axillary lymph nodes excision (>10) (OR = 2.83, 95% CI: 0.94–8.11, p = 0.047), being overweight (≥25 kg/m²) (OR = 2.57, 95% CI: 1.04 – 6.38, p = 0.036), received fewer post-surgery rehabilitation treatment (OR = 2.37, 95% CI: 1.05–5.39, p = 0.036) and hypertension (OR = 2.38, 95% CI: 1.01–5.62, p = 0.043) were associated with an increased risk of BCRL. Meanwhile, multivariate analysis showed that multiple surgeries remained significant and elevated the likelihood of BCRL (OR = 5.83, 95% CI: 1.14–29.78, p = 0.034). Arm swelling was more prominent in the forearm area demonstrated by the highest difference of arm circumference measurement when compared to the upper arm (2.07 ± 2.48 vs. 1.34 ± 1.91 cm, p < 0.001). The total of skinfold thickness of the affected forearm was also significantly higher than the unaffected arms (p < 0.05) as evidenced by the ultrasound examination. The continuous search for risk factors in specific populations may facilitate the development of a standardized method to reduce the occurrence of BCRL and provide better management for breast cancer patients.
