Psychometric characteristics of the Functional Assessment of Cancer Therapy-General when applied to Brazilian cancer patients: a cross-cultural adaptation and validation

Effects of different nutritional support methods on nutritional status and immune function in patients undergoing radiotherapy for head and neck cancer

OBJECTIVE

This study aimed to analyze the effects of different nutritional support methods on nutritional status and immune function of patients undergoing radiotherapy for head and neck cancer (HNC).

METHODS

Patients with HNC were divided into the control (nutritional counseling and routine dietary guidance), parenteral nutrition (PN) (PN support on top of the control group), enteral nutrition (EN) (EN support on top of the control group), and EN + PN (EN combined with PN and routine dietary guidance) groups. After nutrition evaluation, the four groups were subjected to radiotherapy and nutritional support. Body mass index (BMI), serum albumin (ALB), prealbumin (PA), transferrin (TRF), hemoglobin (Hb), CD3+, CD4+, CD8+, CD4+/CD8+, natural killer (NK) and quality of life were compared among the four groups before radiotherapy and after radiotherapy dose irradiation completion. The incidence of adverse reactions was assessed and recorded at 2 weeks, 4 weeks and the end of radiotherapy.

RESULTS

The four groups experienced some degree of malnutrition during radiotherapy and the EN + PN group possessed the lowest degree of malnutrition. After radiotherapy dose irradiation completion (T1), the PN, EN, and EN + PN groups possessed improved BMI (21.42 ± 1.62, 21.40 ± 1.68, 22.98 ± 1.87 vs. 20.18 ± 1.32), serum ALB (31.59 ± 3.49, 32.24 ± 4.23, 37.58 ± 3.23 vs. 26.67 ± 3.03), PA (182.63 ± 13.57, 183.43 ± 14.19, 201.59 ± 10.53 vs. 165.36 ± 20.13), TRF (162.46 ± 24.34, 157.36 ± 18.58, 182.36 ± 20.37 vs. 137.56 ± 23.19), and Hb (128.54 ± 9.21, 125.36 ± 10.23, 140.26 ± 7.23 vs. 103.24 ± 9.47) levels, higher CD3+ (63.59 ± 2.88, 63.25 ± 3.17, 66.54 ± 1.32 vs. 59.36 ± 3.24), CD4+ (39.92 ± 3.16, 39.87 ± 3.23, 43.36 ± 2.87 vs. 37.12 ± 4.29), CD4+/CD8+ (1.80 ± 0.06, 1.78 ± 0.06, 2.07 ± 0.03 vs. 1.54 ± 0.10) and NK-cells (33.87 ± 3.62, 33.26 ± 3.59, 36.82 ± 3.19 vs. 27.36 ± 4.21) levels, lower CD8+ (22.18 ± 1.07, 22.36 ± 1.04, 20.46 ± 1.09 vs. 24.09 ± 1.21) levels, and improved quality of life (79.97 ± 7.96, 80.13 ± 7.98, 91.78 ± 7.38 vs. 71.53 ± 11.70) versus the control group, and the EN + PN group possessed the most pronounced effects (All P < 0.05). During radiotherapy, the incidence of radiotherapy adverse reactions was increased with time (P < 0.05).

CONCLUSION

PN and EN, alone or in combination, can improve the nutritional status, immune function and quality of life of patients undergoing radiotherapy for HNC, and PN combined with EN has the best improvement effect.

The Accuracy of PUMA Questionnaire in Combination With Peak Expiratory Flow Rate to Identify At-risk, Undiagnosed COPD Patients

INTRODUCTION

The English PUMA questionnaire emerges as an effective COPD case-finding tool. We aimed to use the PUMA questionnaire in combination with peak expiratory flow rate (PEFR) to improve case-finding efficacy in Chinese population.

METHODS

This cross-sectional, observational study included two stages: translating English to Chinese PUMA (C-PUMA) questionnaire with linguistic validation and psychometric evaluation, followed by clinical validation. Eligible participants (with age ≥40 years, respiratory symptoms, smoking history ≥10 pack-years) were enrolled and subjected to three questionnaires (C-PUMA, COPD assessment test [CAT], and generic health survey [SF-12V2]), PEFR measurement, and confirmatory spirometry. The C-PUMA score and PEFR were incorporated into a PUMA-PEFR prediction model applying binary logistic regression coefficients to estimate the probability of COPD (PCOPD).

RESULTS

C-PUMA was finalized through standard forward-backward translation processes and confirmation of good readability, comprehensibility, and reliability. In clinical validation, 240 participants completed the study. 78/240 (32.5%) were diagnosed with COPD. C-PUMA exhibited significant validity (correlated with CAT or physical component scores of SF-12V2, both P<0.05, respectively). PUMA-PEFR model had higher diagnostic accuracy than C-PUMA alone (area under ROC curve, 0.893 vs. 0.749, P<0.05). The best cutoff values of C-PUMA and PUMA-PEFR model (PCOPD) were ≥6 and ≥0.39, accounting for a sensitivity/specificity/numbers needed to screen of 77%/64%/3 and 79%/88%/2, respectively. C-PUMA ≥5 detected more underdiagnosed patients, up to 11.5% (vs. C-PUMA ≥6).

CONCLUSION

C-PUMA is well-validated. The PUMA-PEFR model provides more accurate and cost-effective case-finding efficacy than C-PUMA alone in at-risk, undiagnosed COPD patients. These tools can be useful to detect COPD early.

Psychometric Properties of the Functional Assessment of Cancer Therapy-General for Evaluating Quality of Life in Patients With Life-Limiting Illness in the Emergency Department

Background: The Functional Assessment of Cancer Therapy-General (FACT-G) is a widely used quality-of-life measure. However, no studies have examined the FACT-G among patients with life-limiting illnesses who present to emergency departments (EDs). Objective: The goal of this study was to examine the psychometric properties of the FACT-G among patients with life-limiting illnesses who present to EDs in the United States. Methods: This cross-sectional study pooled data from 12 EDs between April 2018 and January 2020 (n = 453). Patients enrolled in the study were adults with one or more of the four life-limiting illnesses: advanced cancer, Congestive Heart Failure, Chronic Obstructive Pulmonary Disease, or End-Stage Renal Disease. We conducted item, exploratory, and confirmatory analyses (exploratory factor analysis [EFA] and confirmatory factor analysis [CFA]) to determine the psychometric properties of the FACT-G. Results: The FACT-G had good internal consistency (Cronbach's alpha α = 0.88). The simplest EFA model was a six-factor structure. The CFA supported the six-factor structure, evidenced by the adequate fit indices (comparative fit index = 0.93, Tucker-Lewis index = 0.92, root-mean-square error of approximation = 0.05; 90% confidence interval: 0.04 - 0.06). The six-factor structure comprised the physical, emotional, work and daily activities-related functional well-being, and the family and friends-related social well-being domains. Conclusions: The FACT-G is a reliable measure of health-related quality of life among patients with life-limiting illnesses who present to the ED. Clinical Trial Registration: NCT03325985.

Music therapy, quality of life and efficacy of immunotherapy for NSCLC

OBJECTIVE

Our study examines how non-small cell lung cancer (NSCLC) survivors undergoing immunotherapy can experience reduced anxiety and psychological distress, improved quality of life (QOL) and increased immunotherapy efficacy.

METHODS

133 men and 20 women with NSCLCs were enrolled. In a randomised controlled trial involving a care as usual group (CG) and a music therapy group (MTG), the researchers employed various tools such as the Self-Rating Anxiety Scale, Symptom Distress Thermometer, Functional Assessment of Cancer Therapy-General version 4 and Response Evaluation Criteria in Solid Tumours. These measures were used to evaluate anxiety, psychological distress, QOL and immunotherapy efficacy in patients undergoing immunotherapy before and after patients' completion.

RESULTS

After the intervention, patients in the MTG demonstrated a noteworthy reduction in anxiety (t=6.272, p≤0.001) and distress (t=10.111, p≤0.001), as well as an increase in QOL (t=-7.649, p≤0.001). Moreover, compared with patients in the CG, those in the MTG demonstrated a remarkable drop in anxiety (t=-4.72, p≤0.001) and distress (t=-7.29, p≤0.001), a significant increase in QOL (t=5.363, p≤0.001) and a significant improvement in immunotherapy efficacy (z=-2.18, p≤0.05) after the intervention.

CONCLUSIONS

The use of individual music therapy sessions appears to be effective in reducing anxiety and distress, while also increasing QOL and immunotherapy efficacy in patients with NSCLCs undergoing immunotherapy.

The early predictive value of frailty for health-related quality of life among elderly patients with cancer receiving curative chemotherapy

Changes in health-related quality of life (HRQOL) among elderly patients with cancer before and after receiving curative treatment, such as chemotherapy, have always been an important consideration in physician-patient treatment decision-making. Although frailty assessment can help predict the effects of chemotherapy, there is a lack of relevant literature on its effectiveness in predicting post-chemotherapy HRQOL. Therefore, this study investigated the early predictive value of pre-chemotherapy frailty assessment for post-chemotherapy HRQOL among elderly patients with cancer receiving curative chemotherapy. From September 2016 to November 2018, this study enrolled elderly patients with cancer aged ≥ 65 years (N = 178), who were expected to receive chemotherapy at three hospitals in Taiwan. The mean age of patients was 71.70 years (SD = 5.46 years) and half of them were female (n = 96, 53.9%). A comprehensive geriatric assessment was performed to measure frailty in 178 participants one week before receiving chemotherapy (T0). Further, the HRQOL of the elderly patients with cancer was assessed again, four weeks after chemotherapy (T1). After controlling for demographic variables, this study evaluated the predictive value of frailty for HRQOL using a hierarchical regression analysis. A total of 103 (57.9%) participants met the frailty criteria. The results showed that 31.1%-56.7% of the variance in the seven domains of HRQOL could be explained by demographic variables and the presence or absence of frailty. This suggests that the presence or absence of frailty is an important predictor of the illness burden domain (β = 9.5; p < .05) of HRQOL. Frailty affects the illness burden domain of HRQOL in elderly patients with cancer. Finally, the administration of frailty assessments before treatment is recommended as a reference for patient treatment decision-making.

Cross-cultural translation and adaptation of Functional Assessment of Cancer Therapy – Multiple Myeloma tool – MM1 and LEU3 – for Portuguese

Objective

To describe of the translation from English to Portuguese and adaption process of subitems of the Functional Assessment of Cancer Therapy – Multiple Myeloma.

Methods

In the first phase, translations from English into Portuguese of two subitems of Functional Assessment of Cancer Therapy – Multiple Myeloma were performed. Subsequently, a consensus and back translation were conducted, and, finally, translation and back translations were reviewed by four independent bilingual experts. In the second phase, the translated subitems were applied, along with a questionnaire, to 10 native Portuguese speakers patients with multiple myeloma.

Results

There was a recognition of the translation process in its first version applied to 10 patients with multiple myeloma, whose reported no difficult to understand the translated and validated instrument. Patients also did not find the content irrelevant or offensive, and they did not suggested changes.

Conclusion

The subitems of the Functional Assessment of Cancer Therapy – Multiple Myeloma were translated from English into Portuguese following the proposed methodology and there was not need of readjustments. This process allowed this instrument of quality of life, which is widely known to be beneficial in the management of patients with multiple myeloma, to be used among our population.

Psychometric Properties of the Arabic Version of the Functional Assessment of Chronic Illnesses Therapy-Fatigue in Arabic Cancer Patients

BACKGROUND

The Functional Assessment of Chronic Illness Therapy (FACIT) is a measurement system that was developed to assess the health-related quality of life among patients with cancer and other chronic illnesses. The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) is a 40-item questionnaire, and it is one of the most frequently used instruments to assess fatigue in cancer populations. The aim of this study was to evaluate the psychometric properties of the Arabic FACIT-F among patients diagnosed with cancer.

METHODS

Following a translated and cross-cultural evaluation procedure of the FACIT-F Arabic version, a cross-sectional and descriptive correlational design was conducted. A total of 369 patients with cancer completed the FACIT-F, which consists of the 27-item Functional Assessment of Cancer Therapy-General (FACT-G) and the 13-item Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). The scale was assessed in terms of acceptability, internal consistency, and validity. Construct validity was explored through confirmatory factor analysis.

RESULTS

The FACT-G had acceptable fit in the four-factor model, whereas the FACIT-Fatigue was found to be acceptable for the one-factor model in Arabic patients diagnosed with cancer. The Cronbach's alpha coefficient for the Arabic FACIT-Fatigue was 0.92, whereas the total score for FACT-G was 0.92, which showed good reliability. There was evidence that discriminated validity analysis was generally very good for the FACIT-Fatigue and FACT-G Arabic versions.

CONCLUSION

The Arabic versions of the FACIT-Fatigue and FACT-G demonstrated good reliability and validity for assessing fatigue and quality of life in patients diagnosed with cancer.

Long-term outcome of spiral ileal neobladder with orthotopic ureteral reimplantation

PURPOSE

The purpose of this study was to analyze long-term complications, urodynamics, and quality of life (QoL) of patients after orthotopic ileal neobladder with orthotopic ureteral reimplantation to enrich clinical data and provide a basis for clinical use of this surgery.

METHODS

Between January 2007 and January 2013, 72 consecutive patients who underwent spiral ileal neobladder following radical cystectomy were enrolled. The neobladder was created using a modified Camey-II technique. Complications were reviewed and staged according to Clavien-Dindo classification and evaluated in long-term follow-up. Urodynamics were performed, and QoL was assessed by the Functional Assessment of Cancer Therapy for Bladder Cancer (FACT-BL) instrument.

RESULTS

The total follow-up time was 60 months, and the total survival rates at 3 and 5 years after surgery were 76.4% (55/72) and 65.3% (47/72), respectively. There were 34 (47.2%) early complications in 23 (31.9%) patients and 42 (58.3%) late complications in 35 (48.6%) patients. The total satisfactory control rates were 69.1% and 66.0% at 3 and 5 years after the surgery, respectively. Urodynamic studies were performed in some patients, and the receiver operating characteristic curve analysis showed that pressure at maximum capacity, compliance, and post void residual urine had predictive value for mortality (P < 0.05). The total FACT-BL scores of patients at 1, 3, and 5 years postoperation were 125.0 ± 15.2, 127.0 ± 16.2, and 120.6 ± 13.5, respectively, and it decreased at 5 years postoperation (P < 0.05).

CONCLUSION

Spiral ileal neobladder with orthotopic ureteral reimplantation offers satisfactory long-term results, and urodynamic monitoring might have prognostic value.

Measuring the Quality of Life among Head-and/or-Neck Cancer Patients with Oral Mucositis Using the Functional Assessment of Cancer Therapy-General in Jordan

Objective:

Quality of life (QOL) in cancer patients can be influenced by the presence of medical conditions, such as oral mucositis (OM). There is still limited knowledge about this issue among patients in Jordan, and this could be related to the absence of research instruments testing QOL among cancer patients with OM. This study measured the QOL among cancer patients using the Functional Assessment of Cancer Therapy-General (FACT-G), Arabic version.

Methods:

This was a cross-sectional study on 118 head-and/or-neck cancer patients with OM in Jordan. Data were submitted to measures of normality, reliability, and validity using exploratory factor analysis. The study also measured QOL among the study sample.

Results:

FACT-G demonstrated good internal consistency reliability and validity. Factor analysis indicated the presence of four factors explained by 24 items representing a valid FACT-G, Arabic version. Scores reflected low QOL compared to reported normative values in the literature. The values used to compare findings from this study were extracted from international literature; no similar values were present in published literature.

Conclusions:

FACT-G, Arabic version, is valid and reliable when applied to this study population. Further testing is recommended, which would include the establishment of normative values.

Psychometric Properties of the Death Anxiety Scale-Extended among Patients with End-Stage Renal Disease

This study aimed to evaluate the validity and reliability of the Persian version of Death Anxiety Scale-Extended (DAS-E). A total of 507 patients with end-stage renal disease completed the DAS-E. The factor structure of the scale was evaluated using exploratory factor analysis with an oblique rotation and confirmatory factor analysis. The content and construct validity of the DAS-E were assessed. Average variance extracted, maximum shared squared variance, and average shared squared variance were estimated to assess discriminant and convergent validity. Reliability was assessed using Cronbach’s alpha coefficient (α = .839 and .831), composite reliability (CR = .845 and .832), Theta (θ = .893 and .867), and McDonald Omega (Ω = .796 and .743). The analysis indicated a two-factor solution. Reliability and discriminant validity of the factors was established. Findings revealed that the present scale was a valid and reliable instrument that can be used in assessment of death anxiety in Iranian patients with end-stage renal disease.

Cross-cultural adaptation and measurement properties of generic and cancer-related patient-reported outcome measures (PROMs) for use with cancer patients in Brazil: a systematic review

Purpose

This systematic review (1) identifies the current generic and cancer-related patient-reported outcome measures (PROMs) that have been cross-culturally adapted to Brazilian Portuguese and applied to cancer patients and (2) critically evaluates their cross-cultural adaptation (CCA) and measurement properties.

Methods

Seven databases were searched for articles regarding the translation and evaluation of measurement properties of generic and cancer-related PROMs cross-culturally adapted to Brazilian Portuguese that are applied in adult (≥18 years old) cancer patients. The methodological quality of included studies was assessed using the COSMIN checklist.

Results

The bibliographic search retrieved 1674 hits, of which seven studies analysing eight instruments were included in this review. Data on the interpretability of scores were poorly reported. Overall, the quality of the CCA process was inconsistent throughout the studies. None of the included studies performed a cross-cultural validation. The evidence concerning the quality of measurement properties is limited by poor or fair methodological quality. Moreover, limited information regarding measurement properties was provided within the included papers.

Conclusions

This review aids the selection process of Brazilian Portuguese PROMs for use in cancer patients. After acknowledging the methodological caveats and strengths of each tool, our opinion is that for quality of life and symptoms assessment the adapted FACT-G version and the ESAS could be recommended, respectively. Future research should rely on the already accepted standards of CCA and validation studies.

Cross-cultural measurement invariance in the satisfaction with food-related life scale in older adults from two developing countries

BACKGROUND

Nutrition is one of the major determinants of successful aging. The Satisfaction with Food-related Life (SWFL) scale measures a person's overall assessment regarding their food and eating habits. The SWFL scale has been used in older adult samples across different countries in Europe, Asia and America, however, there are no studies that have evaluated the cross-cultural measurement invariance of the scale in older adult samples. Therefore, we evaluated the measurement invariance of the SWFL scale across older adults from Chile and Ecuador.

METHODS

Stratified random sampling was used to recruit a sample of older adults of both genders from Chile (mean age = 71.38, SD = 6.48, range = 60-92) and from Ecuador (mean age = 73.70, SD = 7.45, range = 60-101). Participants reported their levels of satisfaction with food-related life by completing the SWFL scale, which consists of five items grouped into a single dimension. Confirmatory factor analysis (CFA) was used to examine cross-cultural measurement invariance of the SWFL scale.

RESULTS

Results showed that the SWFL scale exhibited partial measurement invariance, with invariance of all factor loadings, invariance in all but one item's threshold (item 1) and invariance in all items' uniqueness (residuals), which leads us to conclude that there is a reasonable level of partial measurement invariance for the CFA model of the SWFL scale, when comparing the Chilean and Ecuadorian older adult samples. The lack of invariance in item 1 confirms previous studies with adults and emerging adults in Chile that suggest this item is culture-sensitive. We recommend revising the wording of the first item of the SWFL in order to relate the statement with the person's life.

CONCLUSIONS

The SWFL scale shows partial measurement invariance across older adults from Chile and Ecuador. A 4-item version of the scale (excluding item 1) provides the basis for international comparisons of satisfaction with food-related life in older adults from developing countries in South America.
