Quality of Life of Colorectal Cancer Survivors: Mapping the Key Indicators by Expert Consensus and Measures for Their Assessment

Quality of life (QoL) assessments are integral to cancer care, yet their effectiveness in providing essential information for supporting survivors varies. This study aimed to elucidate key indicators of QoL among colorectal cancer survivors from the perspective of healthcare professionals, and to evaluate existing QoL questionnaires in relation to these indicators. Two studies were conducted: a Delphi study to identify key QoL indicators and a scoping review of questionnaires suitable for colorectal cancer survivors. Fifty-four healthcare professionals participated in the Delphi study's first round, with 25 in the second. The study identified two primary QoL domains (physical and psychological) and 17 subdomains deemed most critical. Additionally, a review of 12 questionnaires revealed two instruments assessing the most important general domains. The findings underscored a misalignment between existing assessment tools and healthcare professionals' clinical priorities in working with colorectal cancer survivors. To enhance support for survivors' QoL, efforts are needed to develop instruments that better align with the demands of routine QoL assessment in clinical practice.

Translation and Validation of a Vietnamese Version of the Colorectal Cancer Subscale for the Functional Assessment of Cancer Therapy - Colorectal Questionnaire

Introduction

There is a need for a validated Vietnamese translation of the colorectal cancer subscale (CCS) of the functional assessment of cancer therapy-colorectal (FACT-C) questionnaire to assess colorectal cancer-specific concerns of Vietnamese persons with colorectal cancer post-surgery.

Objectives

This study aims to translate and validate the CCS of FACT-C questionnaire in Vietnamese persons with colorectal cancer post-surgery.

Methods

The nine-item CCS was translated following the functional assessment of chronic illness therapy (FACIT) translation methodology guidelines. Psychometric properties of a Vietnamese version of the CCS were evaluated with a sample of 135 participants who were randomly selected from three hospitals in Vietnam, utilizing a multistage sampling method. Construct validity was examined through confirmatory factor analysis (CFA), and reliability was assessed using Cronbach's α coefficients. These measures aimed to validate the psychometric properties of the Vietnamese nine-item CCS version. Descriptive statistics were used to analyze participant demographics with SPSS.

Results

The translated version demonstrated equivalence to the original English version. CFA results for the CCS Vietnamese version indicated that all 9 items were consistent with a unidimensional questionnaire (χ2 = 69.669, p > .05, df = 27, χ2/df = 2.58, RMSEA = .074, CFI = .917, TLI = .901, SRMR = .057). The Cronbach's α coefficient was .86, indicating high reliability. The Correlated Item-Total Correlation for the 9 items ranged from .39 to .76.

Conclusion

The nine-item CCS Vietnamese version demonstrated appropriate translation, establishing its validity and reliability in measuring colorectal cancer-related concerns within the health-related quality of life among Vietnamese persons post-surgery.

Transcultural adaptation and validation of the Serbian version of the colorectal-specific quality of life questionnaire FACT-C

OBJECTIVE

Transcultural adaptation and validation of the FACT-C questionnaire to Serbian language.

METHODS

The study included 131 patients with colorectal cancer. Translation included standard forward and backward translation from original language to Serbian and back. Pilot testing of the questionnaire was conducted on 10 patients with diagnosed colorectal cancer. The questionnaires EORTC-QLQ-C30 and DASS will be used as validated tools to evaluate validity of examined, FACT-C questionnaire.

RESULTS

The FACT-C demonstrated satisfactory construct validity using Cronbach's alpha. Satisfactory concurrent validity was demonstrated using correlations with EORTC-QLQ-C30 and DASS questionnaires. High reproducibility was demonstrated using repeated questionnaires on 30 patients two weeks after the first interview.

CONCLUSION

The Serbian version of the FACT-C was demonstrated to have satisfactory applicability, reliability and validity in Serbian patients with colorectal cancer. It can be considered as a valid colorectal cancer specific health related quality of life tool for the Serbian population.

[Evaluation of quality of life: Clinical relevance for patient]

The quality of life of patients and its evaluation remains one of the primordial objectives in oncology. Different methods and tools of evaluation of quality of life have been developed with the objective of having a global evaluation, throughout different aspects, be it physical, emotional, psychological or social. The quality of life questionnaires improve and simplify the reevaluation and follow-up of patients during clinical trials. Patient reported outcome measures (PROMs) are an evaluation of the quality of life as experienced by the patients (patient-reported-outcomes [PROs]) and allow for physicians a personalized treatment approach. In radiotherapy, PROMs are a useful tool for the follow-up of patients during or after treatment. The technological advances, notably in data collecting, but also in their integration and treatment with regard to artificial intelligence will allow integrating these evaluation tools in the management of patients in oncology.

Assessment of sexual dysfunction in patients with perianal Crohn's disease

AIM

Over the past 10 years, several studies have focused on sexuality in patients with Crohn's disease. Very few of them specifically focused on perianal disease (PD). This study aimed to compare the prevalence of sexual dysfunction (SD) in Crohn's disease patients with active PD versus controls without active PD.

METHOD

Patients from 14 French centres with active PD, defined by the presence of symptomatic ulceration, fistula or stenosis, were arbitrarily included. They were compared with controls from the existing SEXIA cohort. Men completed the International Index of Erectile Function (IIEF) and women the Female Sexual Function Index (FSFI). The primary end-point was SD defined by FSFI < 26.55 in women and IIEF < 42.9 in men.

RESULTS

Ninety-seven patients (64 women, 33 men) and 238 controls (131 women, 107 men) were included. SD was found in 66% of the female patients versus 50% of the controls (P = 0.04). In the male population, SD was found in 30% of the cases versus 16% of the controls (P = 0.06). Erectile dysfunction affected 46% of the male patients and 43% of the controls (P = 0.8). On multivariate analysis, the predictive factor most strongly associated with SD in women was severely active anal PD defined by a perineal disease activity index > 4 [OR = 13.05 (2.32-73.44)].

CONCLUSION

Women with active PD had an increased prevalence of SD compared with controls without active PD. In the male population, the study was unable to determine whether there was a difference as it was underpowered.

How health-related quality of life assessment should be used in advanced colorectal cancer clinical trials

Traditionally, the efficacy of cancer treatment in patients with advance or metastatic disease in clinical studies has been studied using overall survival and more recently tumor-based end points such as progression-free survival, measurements of response to treatment. However, these seem not to be the relevant clinical end points in current situation if such end points were no validated as surrogate of overall survival to demonstrate the clinical efficacy. Appropriate, meaningful, primary patient-oriented and patient-reported end points that adequately measure the effects of new therapeutic interventions are then crucial for the advancement of clinical research in metastatic colorectal cancer to complement the results of tumor-based end points. Health-related quality of life (HRQoL) is effectively an evaluation of quality of life and its relationship with health over time. HRQoL includes the patient report at least of the way a disease or its treatment affects its physical, emotional and social well-being. Over the past few years, several phase III trials in a variety of solid cancers have assessed the incremental value of HRQoL in addition to the traditional end points of tumor response and survival results. HRQoL could provide not only complementary clinical data to the primary outcomes, but also more precise predictive and prognostic value. This end point is useful for both clinicians and patients in order to achieve the dogma of precision medicine. The present article examines the use of HRQoL in phase III metastatic colorectal cancer clinical trials, outlines the importance of HRQoL assessment methods, analysis, and results presentation. Moreover, it discusses the relevance of including HRQoL as a primary/co-primary end point to support the progression-free survival results and to assess efficacy of treatment in the advanced disease setting.

The internal and external responsiveness of Functional Assessment of Cancer Therapy-Prostate (FACT-P) and Short Form-12 Health Survey version 2 (SF-12 v2) in patients with prostate cancer

PURPOSE

To examine the responsiveness of Functional Assessment of Cancer Therapy-Prostate (FACT-P) and Short Form-12 Health Survey version 2 (SF-12 v2) in prostate cancer patients because there is a lack of evidence to support their responsiveness in this patient population.

METHODS

One hundred sixty-eight subjects with prostate cancer were surveyed at baseline and at 6 months using the SF-12 v2 and FACT-P version 4. Internal responsiveness was assessed using paired t test and generalized estimating equation. External responsiveness was evaluated using receiver operating characteristic curve analysis.

RESULTS

The internal responsiveness of the FACT-P and SF-12 v2 to detect positive change was satisfactory. The FACT-P and SF-12 v2 could not detect negative change. The FACT-P and the SF-12 v2 performed the best in distinguishing between improved general health and worsened general health. The FACT-P performed better in distinguishing between unchanged general health and worsened general health. The SF-12 v2 performed better in distinguishing between unchanged general health and improved general health.

CONCLUSIONS

Positive change detected by these measures should be interpreted with caution as they might be too responsive to detect "noise," which is not clinically significant. The ability of the FACT-P and the SF-12 v2 to detect negative change was disappointing. The internal and external responsiveness of the social well-being of the FACT-P cannot be supported, suggesting that it is not suitable to longitudinally monitor the social component of HRQOL in prostate cancer patients. The study suggested that generic and disease-specific measures should be used together to complement each other.

Psychometric Validation of the Bahasa Malaysia Version of the EORTC QLQ-CR29

BACKGROUND

This study examined the psychometric properties of the Bahasa Malaysia (BM) version of the European Organization for Research and Treatment of Cancer (EORTC) Colorectal Cancer-specific Quality Of Life Questionnaire (QLQ-CR29).

MATERIALS AND METHODS

We studied 93 patients recruited from University Malaya and Universiti Kebangsaan Medical Centers, Kuala Lumpur, Malaysia using a self-administered method. Tools included QLQ-C30, QLQ-CR29 and Karnofsky Performance Scales (KPS). Statistical analyses included Cronbach's alpha, test-retest correlations, multi-traits scaling and known-groups comparisons. A p value ≤ 0.05 was considered significant.

RESULTS

The internal consistency coefficients for body image, urinary frequency, blood and mucus and stool frequency scales were acceptable (Cronbach's alpha α ≥ 0.65). However, the coefficients were low for the blood and mucus and stool frequency scales in patients with a stoma bag (α = 0.46). Test-retest correlation coefficients were moderate to high (range: r = 0.51 to 1.00) for most of the scales except anxiety, urinary frequency, buttock pain, hair loss, stoma care related problems, and dyspareunia (r ≤ 0.49). Convergent and discriminant validities were achieved in all scales. Patients with a stoma reported significantly higher symptoms of blood and mucus in the stool, flatulence, faecal incontinence, sore skin, and embarrassment due to the frequent need to change the stoma bag (p < 0.05) compared to patients without stoma. None of the scales distinguished between patients based on the KPS scores. There were no overlaps between scales in the QLQ-C30 and QLQ-CR29 (r < 0.40).

CONCLUSIONS

the BM version of the QLQ-CR29 indicated acceptable psychometric properties in most of the scales similar to original validation study. This questionnaire could be used to complement the QLQ-C30 in assessing HRQOL among BM speaking population with colorectal cancer.

Cultural adaptation and validation of the Korean version of the EORTC QLQ-CR29 in patients with colorectal cancer

PURPOSE

We aimed to evaluate the psychometric properties of the Korean version of the European Organization for Research and Treatment of Cancer (EORTC) Colorectal Cancer-Specific Quality of Life Questionnaire (QLQ-CR29), based on a sample of patients with colorectal cancer.

METHODS

A total of 123 patients treated for colorectal cancer participated in the validation study. Test-retest reliability was assessed using intra-class correlations from a random sample. Internal consistency reliability was estimated using Cronbach's α coefficient. Convergent and discriminant validity was analyzed with multi-trait scaling. Clinical validity was assessed in terms of clinical differences using known-group comparisons. Concurrent validity was determined by correlations with the EORTC QLQ-C30, which was a generic core questionnaire to evaluate issues common to different cancer sites and treatments.

RESULTS

The test-retest, administered to 35 patients, showed acceptable reproducibility (0.62-1.00) except the constipation scale of the QLQ-C30 (0.43). Cronbach's α coefficient (0.70-0.87) exceeded the 0.7 criterion. Multi-trait scaling analysis showed that multi-item scales met standards of convergent and discriminant validity. The known-group comparisons showed quality of life (QOL) differences between groups of patients based on tumor location, receipt of neoadjuvant therapy, and with/without a stoma. Correlations between the scales of the QLQ-CR29 and QLQ-C30 were low in most areas, whereas correlations in several areas with related content were higher.

CONCLUSION

This study shows that the Korean version of the EORTC QLQ-CR29 is a reliable and valid tool for measuring QOL, as determined by application to a sample of Korean colorectal cancer patients.

Systematic review of health-related quality of life issues in locally recurrent rectal cancer

The standardization of surgical techniques supplemented with appropriate neoadjuvant chemoradiation has led to the decline in local recurrence rates of rectal cancer (LRRC) from 25-50% to 5-10%. The outcomes reported for surgical intervention in LRRC is encouraging, however, a number of controversies exist especially in the ultra-advanced and palliative setting. Incorporating health-related quality of life (HRQoL) outcomes in this field could supplement traditional clinical endpoints in assessing the effectiveness of surgical intervention in this cohort. This review aimed to identify the HRQOL themes that might be relevant to patients with LRRC. A systematic review was undertaken to identify all studies reporting HRQoL in LRRC. Each study was evaluated with regards to its design and statistical methodology. A meta-synthesis of qualitative and quantitative studies was undertaken to identify relevant HRQoL themes. A total of 14 studies were identified, with 501 patients, with 80% of patients undergoing surgery. HRQoL was the primary endpoint in eight studies. Eight themes were identified: physical, psychological and social impact, symptoms, financial and occupational impact, relationships with others, communication with healthcare professionals and sexual function. The impact on HRQoL is multifactorial and wide ranging, with a number of issues identified that are not included in current measures. These issues must be incorporated into the assessment of HRQoL in LRRC through the development of a validated, disease-specific tool.

Systematic review recommends the European Organization for Research and Treatment of Cancer colorectal cancer-specific module for measuring quality of life in colorectal cancer patients

OBJECTIVES

To critically appraise the measurement properties of standardized health-related quality of life (HRQOL) instruments for colorectal cancer (CRC) patients and to provide recommendations on the choice of HRQOL instruments.

STUDY DESIGN AND SETTING

Systematic review of English language literature published between January 1985 and May 2014 identified through a database search of PubMed, Web of Science, Embase, and Ovid MEDLINE. HRQOL instruments were rated on methodological quality and overall levels of evidence using a Consensus-based Standards for the selection of health Measurement Instrument checklist.

RESULTS

Internal consistency and hypothesis testing were evaluated most frequently in 63 studies identified. The Functional Assessment of Cancer Therapy-Colorectal (FACT-C) was the most extensively evaluated. The highest number of positive ratings in the overall level of evidence was found in the CRC-specific quality of life questionnaire module (QLQ-CR38) in European Organization for Research and Treatment of Cancer (EORTC) module, followed by the Memorial Sloan Kettering Cancer Center Bowel instrument, FACT-C, and Quick-FLIC. The EORTC QLQ-CR38 had the most positive ratings on measurement property and was recommended.

CONCLUSION

The EORTC QLQ-CR38 was recommended to assess HRQOL in patients with CRC, regardless of disease stage and primary tumor site.

Health related quality of life in colorectal cancer patients: state of the art

Background

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in males and the second in females with a progressive increase in prevalence in industrialized countries. The loss of health due to the cancer and/or the consequence of the treatment may result in psychophysical, functional and social impairment; all of these affect health-related quality of life (QoL).

Description

The most frequently CRC-specific QoL questionnaires is the FACT-C. QoL is not only important for the well-being of cancer patient but it also influences survival and response to therapy. Many studies investigated various determinants involved in the assessment of QoL in CRC, suggesting that symptoms, surgical procedures and the number of comorbidity significantly affected QoL.

Conclusion

Despite that CRC patients have a relatively good QoL compared with the general population, a wide range of intervention could be undertaken to improve their QoL. The finding of this review may be useful for cancer clinicians in taking therapy and surveillance-related decisions. However, future research should be directed to large-scale prospective studies using well validated QoL instruments to facilitate comparison of results.

Validation of the Danish version of the disease specific instrument EORTC QLQ-CR38 to assess health-related quality of life in patients with colorectal cancer

Background

The European Organisation for Research and Treatment of Cancer (EORTC) quality of life colorectal questionnaire module (QLQ-CR38) was developed in 1999, and an update, the QLQ CR29 was published recently. To date the Danish version of the questionnaire has not been validated. The aim of this study was to examine the psychometric properties of the Danish version of EORTC QLQ-CR38.

Methods

EORTC QLQ-CR38 was administered to 190 patients with colorectal cancer in two Danish hospitals, one month after their operation. A psychometric evaluation of the questionnaire’s structure, reliability, convergent, divergent and known-groups validity was performed.

Results

Data from 164 (86.3%) patients were available for analysis. The Danish version of EORTC QLQ-CR38 showed satisfactory psychometric properties for the scales: body image, sexual functioning, male sexual problems and defecations problems. Suboptimal psychometric performances were found for the scales: micturition problems, symptoms of the gastrointestinal tract and weight loss. Evaluation of the psychometric properties of the scale chemotherapy side effects was limited by the low number of patients receiving chemotherapy. It was not possible to assess the psychometric properties of the scale female sexual problems and the single item sexual enjoyment due to a high number of missing values. The homogeneity of the study population made the evaluation of known-group validity difficult.

Conclusions

The results of this study suggest that the validity of the Danish version of EORTC QLQ-CR38 is acceptable. Furthermore, the results support the appropriateness of the updated version, the EORTC QLQ-CR29.

Validity and reliability study on traditional Chinese FACT-C in Chinese patients with colorectal neoplasm

OBJECTIVE

To establish the validity and reliability of traditional Chinese version of the Functional Assessment of Cancer Therapy-Colorectal (FACT-C).

METHODS

A total of 536 subjects self-administered (n = 331) or interviewer-administered (n = 205) FACT-C (version 4), EORTC QLQ-C30/CR38 and SF-12v2 instruments for health-related quality of life assessment. Construct validity was examined by item-scale correlation, scaling success and concurrent validity. Reliability was evaluated by test-retest reliability and internal consistency. Sensitivity was assessed by known-groups comparisons.

RESULTS

The completion rates for FACT-C were almost perfect (>98%). The FACT-C demonstrated item-internal consistency and item discriminant validity through item-scale correlation. Scaling success and concurrent validity were satisfactory to support the construct validity. The five subscales of the FACT-C showed good internal consistency with Cronbach alpha coefficient and substantial reproducibility, demonstrating good reliability. Sensitivity was supported when there were significant differences in scores related to physical condition between patients who were receiving treatment and those who were not.

CONCLUSION

Traditional Chinese version of the FACT-C was demonstrated to have satisfactory psychometric properties in terms of applicability, reliability, validity and sensitivity in Chinese patients with colorectal neoplasm. The FACT-C was valid colorectal-specific health-related quality of life tool for the Chinese population.

Measurement invariance of the Functional Assessment of Cancer Therapy-Colorectal quality-of-life instrument among modes of administration

OBJECTIVES

To test for the measurement invariance of the Functional Assessment of Cancer Therapy-Colorectal (FACT-C) in patients with colorectal neoplasms between two modes of administration (self- and interviewer administrations). It is important to establish the measurement invariance of the FACT-C across different modes of administration to ascertain whether it is valid to pool FACT-C data collected by different modes or to assess each group separately.

METHODS

A cross-sectional sample of 391 Chinese patients with colorectal neoplasms was recruited from specialist outpatient clinics between September 2009 and July 2010. Confirmatory factor analysis (CFA) was used to test the original five-factor model of the FACT-C on data collected by self- and interviewer administrations in single-group analysis. Multiple-group CFA was then used to compare the factor structure between the two modes of administration using chi-square tests and other goodness-of-fit statistics.

RESULTS

The hypothesized five-factor model of FACT-C demonstrated good fit in each group. Configural invariance and metric invariance were fully supported in multiple-group CFA. Some item intercepts and their corresponding error variances were not identical between administration groups, suggesting evidence of partial strict factorial invariance.

CONCLUSIONS

Our results confirmed that the five-factor structure of FACT-C was invariant in Chinese patients using both self- and interviewer administrations. It is appropriate to pool or compare data in the emotional well-being and colorectal cancer subscale scores collected by both administrations. Measurement invariance in three items, one from each of the other subscales, may be contaminated by response bias between modes of administration.

Quality-of-life and surgical treatments for rectal cancer--a longitudinal analysis using the California Cancer Registry

BACKGROUND

Heterogeneous results for research investigating health-related quality of life (HRQL) in patients undergoing sphincter-ablating procedures for rectal cancer are likely due to single institution experiences and measurement of HRQL. To address this heterogeneity, we evaluated HRQL in patients with rectal cancer by type of surgery, location of tumor, and receipt of adjuvant therapy using an HRQL instrument that has not been used to address rectal cancer patients in a population-based sample over time.

METHODS

The Functional Assessment of Cancer Therapy-Colorectal instrument was administered at 9 and 19 months after diagnosis to a consecutive sample of 160 patients in Northern California identified by the California Cancer Registry. A broad multidimensional interpretation of HRQL was used to examine the impact of tumor location and treatment status, stage of disease, age, and gender.

RESULTS

In general, men had lower social well-being scores, and younger patients had lower physical and emotional well-being scores and colorectal concerns scores. We found no differences in HRQL by either tumor location or type of surgery, at either 9 or 19 months after diagnosis. Lower physical well-being and greater adverse colorectal concerns were reported at 9 months among patients who received adjuvant therapy; however, only adverse colorectal concerns persisted over time.

CONCLUSIONS

This study provides additional evidence that sphincter-ablating procedures do not necessarily reduce quality of life in patients with rectal cancer. Distinctive features of this study include a broad multidimensional interpretation of HRQL, the 19 months of longitudinal follow-up, and a prospective population-based study design.

Quality-of-life findings from a randomised phase-III study of XELOX vs FOLFOX-6 in metastatic colorectal cancer

BACKGROUND

A phase-III trial showed the non-inferiority of oral capecitabine plus oxaliplatin (XELOX) vs 5-fluorouracil/leucovorin plus oxaliplatin (FOLFOX-6) in terms of efficacy in first-line treatment of metastatic colorectal cancer. A secondary objective was to compare the quality of life (QoL) and health-care satisfaction of patients.

METHODS

Patients were randomised to receive XELOX (n=156) or FOLFOX-6 (n=150) for 6 months. Quality of life and satisfaction were assessed by the Quality of Life Questionnaire-C30 (QLQ-C30) and Functional Assessment of Chronic Illness Therapy Chemotherapy Convenience and Satisfaction Questionnaire (FACIT-CCSQ), respectively. Patients completed questionnaires at baseline, at Cycle3 (C3) and Cycle (C6) (XELOX) or at C4 and C8 visits (FOLFOX-6) and at their final visit.

RESULTS

A total of 245 and 225 patients were assessed using QLQ-C30 and FACIT-CCSQ, respectively. The completion rates were >80%. Global QoL scores did not differ significantly between groups during the study. According to FACIT-CCSQ, XELOX seemed more convenient (C3/C4, P<0.001; C6/C8, P=0.009) and satisfactory to patients (C6/C8, P=0.003) than FOLFOX-6. At the final visit, XELOX patients spent fewer days on hospital visits (3.3 vs 5.3 days, P=0.045) and lost fewer hours of work/daily activities (10.2 vs 37.1 h lost, P=0.007).

CONCLUSION

XELOX has a similar QoL profile, but seemed to be more convenient in terms of administration at certain time points and reduced time lost for work or other activities compared with FOLFOX-6.
