Can changes in health related quality of life scores predict survival in stages III and IV colorectal cancer?

Global quality of life and mortality risk in patients with cancer: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aimed to examine the impact of global quality of life (QOL) on mortality risk in patients with cancer, considering cancer type and timepoint of QOL assessment.

METHODS

A systematic search was conducted using Cumulated Index to Nursing and Allied Health Literature, PubMed/MEDLINE, and Scopus databases from inception to December 2022. Observational studies that assessed QOL and examined mortality risk in patients with cancer were extracted. Subgroup analyses were performed for cancer types and timepoints of QOL assessment.

RESULTS

Overall, global QOL was significantly associated with mortality risk (hazard ratio: 1.06, 95% confidence interval: 1.05-1.07; p < 0.00001). A subgroup analysis based on cancer type demonstrated that lung, head and neck, breast, esophagus, colon, prostate, hematologic, liver, gynecologic, stomach, brain, bladder, bone and soft tissue, and mixed type cancers were significantly associated with mortality risk; however, melanoma and pancreatic cancer were not significantly associated with mortality risk. Additionally, global QOL was associated with mortality risk at all timepoints (pretreatment, posttreatment, and palliative phase); pretreatment QOL had the largest impact, followed by posttreatment QOL.

CONCLUSION

These findings provide evidence that QOL is associated with mortality risk in patients with cancer at any timepoint. These results indicate the importance of evaluating the QOL and supportive interventions to improve QOL in any phase.

Quality of Life of Colorectal Cancer Patients and Its Association With Anxiety and Depression: Cross-Sectional Study at a Tertiary Care Hospital in Low Middle Income Country

INTRODUCTION

Colorectal cancer (CRC) and its therapy profoundly affect the quality of life (QoL) of patients. The emotional distress: anxiety and depression also negatively affect wellbeing of these patients. This study aims to evaluate the QoL, anxiety, and depression in CRC patients and their association with clinic-pathological features at a tertiary care hospital in Karachi Pakistan, a low middle income country.

METHODS

An analytical cross-sectional study was conducted on adult CRC patients. QoL was assessed using the European Organization for Research and Treatment of Cancer QoL questionnaire C30 and CR29. Hospital Anxiety and Depression Score was used to evaluate the anxiety and depression. Analyses were performed using STATA version 12, including multivariable linear and multivariate analysis of variance. A P value of < 0.05 was considered as significant.

RESULTS

A total of 127 CRC patients with mean age of 53 ± 15 y participated. Mean global QoL score was 69.08 ± 1.78. Among symptoms scales: stoma care problem and among functional scales: sexual interest (women > men) were the most significantly affected aspect. Anxiety and depression were seen in 26 (20.9%) and 24 (18.9%) patients, respectively. Lower global QoL was significantly associated with depression (-25.33 [95% confidence interval: -34.4, -16.23]), on adjuvant treatment (-15.14 [-21.84, -8.44]), and neoadjuvant treatment (-11.75 [-19.84, -3.65]).

CONCLUSIONS

This is the first study assessing the QoL in CRC patients in Pakistan. Depression was found to be significantly associated with poor QoL. Numerous factors correlated with low QoL scores indicating the need to develop local guidelines to address psychological distress in our patients.

Quality of Life in Locally Advanced Carcinoma Rectum Patients During Various Phases of NACRT: An Indian Perspective

In low- and middle-income countries (LMICs) including India, cancer patients have a poor prognosis because of late diagnosis and cases already grown to advanced stages, low cancer awareness and skewed cancer care facilities. In India, the incidence of colorectal cancer (CRC) is ranked the 4th most common (6.4%) in males and the 5th most common (3.4%) in females. The improvement in the cure rate of rectal cancer has increased life expectancy, and assessment of the quality of life (QoL) in these patients has become a fundamental requirement. Little is known about how the patients perceive these adverse effects during curatively intended radiotherapy. Although studies have investigated the various adverse effects that can occur with radiotherapy and chemotherapy in carcinoma rectum patients, these have not yet been critically appraised and synopsized to form a comprehensive review of their prevalence and effects on QoL. The study was designed to explore the QoL issues in locally advanced carcinoma rectum patients during various phases of neoadjuvant concurrent chemo-radiotherapy (NACCRT). The study was performed over a period of 2 years at a single super speciality cancer hospital in North India. Patients were selected as per the inclusion criteria and followed up with a standard questionnaire incorporating various aspects depicting QoL. The interview technique was used for collecting QoL data at four points, at baseline, midway during treatment, at the end of treatment and 4 weeks after completion of NACCRT, using EORTC QLQ C30, for QLQ CR29. Special care was taken to avoid observer bias in cases of language issues, and interpreters' services were utilised, and compared with the baseline pre-treatment scores, patients reported a statistically significant and large clinically meaningful change in the global health status, social functioning, fatigue (FACIT-F), appetite loss, anxiety, sore skin and male and female sexual function at the post-treatment time point. Statistically significant changes with moderate clinically meaningful changes were reported for the functional scales-physical, role and emotional functioning of the QLQ C30 questionnaire and body image and weight of the CR29 questionnaire. Similar moderate clinical changes were found in the symptom scales-fatigue, nausea and vomiting, insomnia, constipation and diarrhoea of QLQ C30 and stool frequency, embarrassment with bowel function, impotence and dyspareunia. These parameters returned to almost the pre-treatment values after 4 weeks of completion of NACRT. Since QoL is a relatively subjective variable, differences in human race, culture, education and social environment will have impacts on the results. International cooperation is needed to study the QoL in patients with multiple cultural backgrounds. The existing QoL questionnaire tools have been designed with Western countries in mind, and we did face multiple social issues. We suggest that many similar multicentre studies shall be required to essentially tap the accurate QoL-related issues keeping in mind the diverse social, economic, racial and educational backgrounds. As we deal with the ever-increasing cancer menace and better life expectancy, QoL issues shall be a major determinant of treatment success besides primary treatment. These factors should form an integral part of treatment modality, and adequate counselling must be performed prior to initiation of care.

Baseline functioning scales of EORTC QLQ-C30 predict overall survival in patients with gastrointestinal cancer: a meta-analysis

PURPOSE

A consensus has not been reached on the value of quality of life (QoL) as a prognostic factor for survival in gastrointestinal cancer. This meta-analysis aimed to investigate the association between functioning scales of the EORTC QoL Questionnaire Core 30 (QLQ-C30) and the overall survival (OS) in patients with gastrointestinal cancer.

METHODS

A systematic literature search was conducted in PubMed, Web of Science, and Embase databases, until February 7, 2023. The studies included were those that investigated the association between baseline QoL measured by the functioning scales of EORTC QLQ-C30 and OS in patients with gastrointestinal cancer. The prognostic capacity of QoL was calculated by pooling the adjusted hazard ratios (HR) with 95% confidence intervals (CI).

RESULTS

Twenty-four studies' analyses reported by 22 eligible articles involving 11,609 patients were included. When compared with good parameters of QoL, poor global QoL (HR 1.81; 95% CI 1.53-2.13), physical functioning (HR 1.51; 95% CI 1.31-1.74), social functioning (HR 1.67; 95% CI 1.30-2.15), and role functioning scale (HR 1.42; 95% CI 1.20-1.29) were significantly associated with decreased OS. For each 10-point increase in QLQ-C30 parameters, the pooled HR of OS was 0.87 (95% CI 0.83-0.92) for global QoL, 0.87 (95% CI 0.83-0.92) for physical functioning, and 0.93 (95% CI 0.88-0.97) for role functioning. However, each 10-point increase in social, emotional, or cognitive functioning scale did not significantly predict OS.

CONCLUSIONS

Baseline health-related QoL defined by the physical functioning or global QoL scale of EORTC QLQ-C30 significantly predicts OS in patients with gastrointestinal cancer.

Impacts of systemic treatments on health-related quality of life for patients with metastatic colorectal cancer: a systematic review and network meta-analysis

OBJECTIVE

There is limited evidence of comparative results among different treatments regarding impacts of Health-Related Quality of Life (HRQoL) for patients with metastatic colorectal cancer (mCRC). We aimed to compare efficacy of systemic treatments on HRQoL among patients with mCRC.

METHODS

We collected randomized controlled trials (RCTs) reported in English up until July 2023, from databases including PubMed, Embase, Cochrane Library, ClinicalTrials.gov, and prominent conference databases, for this Bayesian network meta-analysis. Phase 2 or 3 trials that evaluated at least two therapeutic regimens were included. Primary outcomes were short-term and long-term mean changes in EORTC QLQ-C30 global health status/quality of life (GHS/QoL) scores. Secondary outcome was mean change in EQ-5D health utility scores. Mean differences (MDs) with 95% confidence intervals (CIs) were used as effect size. Subgroup analysis was performed based on whether patients received systemic treatments before. We conducted various sensitivity analyses, including differentiating between chemotherapy types, and analyzed patient cohorts with non-specified gene expression levels as well as those with target KRAS expression statuses. The current systematic review protocol was registered on PROSPERO (CRD42023453315 and CRD42023420498).

RESULTS

Immunotherapy and targeted therapy significantly improved HRQoL over chemotherapy, with MDs of 9.27 (95% CI: 3.96 to 14.6) and 4.04 (95% CI: 0.11 to 7.94), respectively. Monotherapy significantly outperformed both combination therapy (MD 5.71, 95%CI 0.78 to 10.63) and no active treatment (MD 3.7, 95%CI 1.41 to 6.01) regarding GHS/QoL in the short-term. Combining targeted therapy with chemotherapy did not improve HRQoL. Focusing on HRQoL, cetuximab excelled when gene expression baselines were unspecified. Subgroup and sensitivity analyses upheld these robust findings, unaffected by model or patient baseline characteristics. Evidence from clinical trials without specific gene level data suggested that monotherapies, especially targeted therapies such as cetuximab, demonstrated superiority in HRQoL. For KRAS wild-type patients, no significant HRQoL differences emerged between chemotherapy, targeted therapy, or their combination..

CONCLUSIONS

Targeted therapies and immunotherapy demonstrate superior HRQoL benefits, monotherapy such as cetuximab is associated with significant improvements as compared to combination therapy. However, tailoring these results to individual gene expression profiles requires more evidence.

Reliability and validity of the Turkish version of the New Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire

PURPOSE

This study aims to adapt and validate the Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire (CCF-CaQL) in Turkish, addressing the significant need for reliable, language-specific QoL measures for colorectal cancer (CRC) in Turkiye. This effort fills a critical gap in CRC patient care, enhancing both patient-provider communication and disease-specific QoL assessment.

METHODS

The CCF-CaQL was translated into Turkish, verified for accuracy, and reviewed for clarity and relevance. Eligible patients who underwent colorectal surgery for cancer between July 2021 and July 2022 from six hospitals completed the CCF-CaQL and SF-36 questionnaires. For analysis, confirmatory factor analysis using Smart PLS 4 and descriptive statistics were employed. The questionnaire's reliability and validity were assessed using Cronbach alpha, composite reliability, and the heterotrait-monotrait (HTMT) ratio, along with multicollinearity checks and factor loadings. Nonparametric resampling was used for precise error and confidence interval calculations, and the Spearman coefficient and split-half method were applied for reliability testing.

RESULTS

In the study involving 244 colorectal cancer patients, confirmatory factor analysis of the CCF-CaQL indicated effective item performance, with one item removed due to lower factor loading. The questionnaire exhibited high internal consistency, evidenced by a Cronbach alpha value of 0.909. Convergent validity was strong, with all average variance extracted (AVE) values exceeding 0.4. Discriminant validity was confirmed with HTMT coefficients below 0.9, and no significant multicollinearity issues were observed (VIF values < 10). Parallel testing with the SF-36 scale demonstrated moderate to very strong correlations, affirming the CCF-CaQL's comparability in measuring quality of life.

CONCLUSION

The Turkish version of the CCF-CaQL was validated for assessing quality of life in colorectal cancer patients. This validation confirms its reliability and cultural appropriateness for use in Turkiye. The disease-specific nature of the CCF-CaQL makes it a useful tool in clinical and research settings, enhancing patient care by accurately monitoring treatment effects and interventions in the Turkish colorectal cancer patient population.

Time to deterioration of patient-reported outcomes as a surrogate of overall survival: a meta-analysis

BACKGROUND

Overall survival is the optimal marker of treatment efficacy in randomized clinical trials (RCTs) but can take considerable time to mature. Progression-free survival (PFS) has served as an early surrogate of overall survival but is imperfect. Time to deterioration in quality of life (QOL) measures could be a surrogate for overall survival.

METHODS

Phase 3 RCTs in solid malignancies that reported overall survival, PFS, and time to deterioration in QOL or physical function published between January 1, 2010, and June 30, 2022, were evaluated. Weighted regression analysis was used to assess the relationship between PFS, time to deterioration in QOL, and time to deterioration in physical function with overall survival. The coefficient of determination (R2) was used to quantify surrogacy.

RESULTS

In total, 138 phase 3 RCTs were included. Of these, 47 trials evaluated immune checkpoint inhibitors and 91 investigated non-immune checkpoint inhibitor agents. Time to deterioration in QOL (137 RCTs) and time to deterioration in physical function (75 RCTs) performed similarly to PFS as surrogates for overall survival (R2 = 0.18 vs R2 = 0.19 and R2 = 0.10 vs R2 = 0.09, respectively). For immune checkpoint inhibitor studies, time to deterioration in physical function had a higher association with overall survival than with PFS (R2 = 0.38 vs R2 = 0.19), and PFS and time to deterioration in physical function did not correlate with each other (R2 = 0). When time to deterioration in physical function and PFS are used together, the coefficient of determination increased (R2 = 0.57).

CONCLUSIONS

Time to deterioration in physical function appears to be an overall survival surrogate measure of particular importance for immune checkpoint inhibitor treatment efficacy. The combination of time to deterioration in physical function with PFS may enable better prediction of overall survival treatment benefit in RCTs of immune checkpoint inhibitors than either PFS or time to deterioration in physical function alone.

Swallowing disorders and mortality in adults with advanced cancer outside the head and neck and upper gastrointestinal tract: a systematic review

BACKGROUND

Although oncological palliative care is increasingly being offered by multidisciplinary teams, there is still a lack of data about some symptoms handled by these teams, such as dysphagia, in patients with advanced cancer outside swallow regions. This study aimed to estimate the occurrence of dysphagia in prognosis studies of adults with advanced cancer outside the head, neck, and upper gastrointestinal tract, and to determine if there is an association with mortality.

METHODS

A systematic review of studies that evaluated dysphagia and mortality was conducted (PROSPERO: CRD42021257172).

DATA SOURCES

BVS, PubMed, CINAHL, Web of Science, and Scopus. Data between 2011 and 2023 were selected.

RESULTS

Among the 608 articles screened, only 14 were included, which covered different types of cancer, primarily Lung, and Genitourinary, Skin, Hematological, and Central Nervous System as well. Dysphagia demonstrated a variable frequency, and almost half of the studies found a percentage of dysphagia above 60%, appearing most as a symptom that affects health-related quality of life and prove to be a toxicity of treatment. The association between dysphagia and mortality was only evaluated in three articles that studied advanced lung cancer, in which, after controlling for covariates, swallowing disorders were associated with worse survival, with prevalences of dysphagia and hazard ratios of 78.5% (1.12 [1.04-1.20]), 4% (1.34 [1.28-1.35]), and 3% (1.40 [1.07-1.81]), respectively.

CONCLUSIONS

The occurrence of dysphagia in advanced cancer outside the head, neck, and upper GI tract is common, and there seems to be an association with significantly decreased survival in patients with advanced lung cancer.

The Impact of Bevacizumab and Chemotherapy on Quality of Life in Metastatic Colorectal Cancer Patients

Health-related quality is of life of great importance in cancer care. This prospective study aimed to evaluate the impact of chemotherapy and bevacizumab on the activities of daily living, cancer symptoms, and general well-being in 59 metastatic colorectal cancer patients. We gathered information using the EORTC QLQ-C30 and QLQ-CR29 questionnaires. The paired sample t-test, MANOVA test, and Pearson's correlation test were used to analyze the presence of significant differences in mean scores before and after 6 months of treatment. The results revealed significant differences in the functioning and symptoms that influence patients' quality of life after 6 months of treatment: increased pain (p = 0.003), nausea and vomiting (p = 0.003), diarrhea (p = 0.021) and decreased appetite (p = 0.003). At the same time, there were several aspects that improved the quality of life. Increases in emotional function (p = 0.009), cognitive function (p = 0.033), and perception of body image (p = 0.026) were observed after 6 months of treatment. Elderly patients reported a higher frequency of stools (p = 0.028), and young patients had increased concerns about body perception (p = 0.047). Assessing the quality of life of metastatic colorectal cancer patients is an important way to identify and treat symptoms related to both cancer and therapy by establishing a holistic care plan and implementing measures to increase the quality of life.

Racial and Ethnic Disparity in Preference-Weighted Quality of Life: Findings from the Selenium and Vitamin E Cancer Prevention Trial

Differences in preference-weighted health-related quality of life (HRQOL) scores by race/ethnicity may be due to social factors. Here, Short-Form Six-Dimension (SF-6D) scores are analyzed among men in a prostate cancer prevention trial to explore such differences. Selenium and vitamin E cancer prevention trial participants who completed the SF-6D at baseline, and in at least 1 of follow-up years 1, 3, and 5 were included. This study compared mean SF-6D scores across race/ethnicity at each point using a linear mixed model controlling for demographic and clinical characteristics. At baseline, 9691 men were eligible for analysis, of whom 7556 (78%) were non-Hispanic White, 1592 (16.4%) were non-Hispanic Black, and 543 (5.6%) were Hispanic. Hispanic and White participants had higher unadjusted mean SF-6D scores than Black participants at every time point (P < 0.05), while white participants had lower mean scores than Hispanic participants at every time point after baseline (P < 0.05). After adjusting for covariates, statistically significant differences in HRQOL among the 3 groups persisted. Hispanic participants had higher preference scores than White participants by 0.073 (P < 0.001), 0.075 (P < 0.001), and 0.040 (P < 0.001) in follow-up years 1, 3, and 5, respectively. Black participants had lower scores than White participants by 0.009 (P = 0.004) and 0.008 (P = 0.02) in follow-up years 1 and 3, respectively. The results suggest there is a preference-weighted HRQOL difference by race/ethnicity that cannot be explained by social and clinical variables alone. Understanding how individuals belonging to different racial/ethnic categories view their own HRQOL is necessary for culturally competent care and cost-effectiveness analyses.

Different effects between the current capability of and changes in self-management strategies on improving health behavior and psychological health after 6 months: evidence from a prospective cohort study of patients with cancer

PURPOSE

We aimed to examine different effects of the current capability of and changes in self-management strategies on improving health behavior and psychological health (satisfaction of life, depression, and anxiety) after 6 months in cancer patients.

METHODS

A prospective cohort study was conducted, including 540 cancer patients. We measured cancer patients' self-management strategies' capability with Smart Management Strategies for Health (SMASH) Assessment Tool (SAT) baseline scores and changes with SMASH change scores based on a clinically meaningful 10% change of the scores. We conducted adjusted multivariate multiple logistic regression analyses using the stepwise selection method between SMASH baseline and health behavior, satisfaction with life (SWL), depression, and anxiety and between SMASH changes and health behavior, SWL, depression, and anxiety.

RESULTS

256 cancer patients completed both the first and second surveys. While various SMASH capabilities positively affected each health behavior, SWL, depression, and anxiety, the positive-reframing strategy at baseline only affected all health behavior, SWL, and depression. However, based on SMASH changes, using the positive-reframing strategy a lot for 6 months adversely affected some physical health behaviors' practice (balanced diet and stop smoking and drinking). Changes in the life value pursuing strategy only positively affected HB (proactive living) and anxiety.

CONCLUSION

SMASH baseline and change scores were generally associated with practicing cancer patients' health behaviors, lower depression, and anxiety. However, it is necessary to consider that excessively using the positive-reframing strategy would interfere with practicing a balanced diet and stopping smoking and drinking behaviors.

Evaluating the Safety and Quality of Life of Colorectal Cancer Patients Treated by Autologous Immune Enhancement Therapy (AIET) in Vinmec International Hospitals

(1) Colorectal cancer (CRC) is an increasingly prevalent disease with a high mortality rate in recent years. Immune cell-based therapies have received massive attention among scientists, as they have been proven effective as low-toxicity treatments. This study evaluated the safety and effectiveness of autologous immune enhancement therapy (AIET) for CRC. (2) An open-label, single-group study, including twelve patients diagnosed with stages III and IV CRC, was conducted from January 2016 to December 2021. Twelve CRC patients received one to seven infusions of natural killer (NK)-cell and cytotoxic T-lymphocyte (CTL). Multivariate modelling was used to identify factors associated with health-related quality-of-life (HRQoL) scores. (3) After 20−21 days of culture, the NK cells increased 3535-fold, accounting for 85% of the cultured cell population. Likewise, CTLs accounted for 62.4% of the cultured cell population, which was a 1220-fold increase. Furthermore, the QoL improved with increased EORTC QLQ-C30 scores, decreased symptom severity, and reduced impairment in daily living caused by these symptoms (MDASI-GI report). Finally, a 14.3 ± 14.1-month increase in mean survival time was observed at study completion. (4) AIET demonstrated safety and improved survival time and HRQoL for CRC patients in Vietnam.

Health-Related Quality of Life, Functioning, and Physical Symptoms of Adult Omani Colorectal Cancer Survivors

BACKGROUND

Colorectal (CRC) survivors often experience physical and psychological symptoms affecting their health-related quality of life (HRQoL). This study aimed to identify factors impacting HRQoL-related functioning and physical symptoms among adult Omani CRC survivors.

METHODS

A cross-sectional study of 124 adult CRC survivors was conducted at the two main oncology referral hospitals in Oman. A validated Arabic version of the European Organization for Research and Treatment of Cancer-Quality of Life Questionnaire 30 was used to collect data.

RESULTS

A total of 118 CRC survivors participated in the study (response rate: 95.2%). The mean age was 52 years and there were an equal number of male and female participants (n = 59 each; 50.0%). A total of 62 survivors (52.5%) had been diagnosed with CRC at stages III or IV. The overall score for global health was high (81.7). With regards to functioning, high mean scores were observed for domains of role (91.0) and social (90.7) functioning. In terms of symptoms, high mean scores were reported for constipation (25.4), insomnia (25.1), pain (20.1), and fatigue (18.9). Survivors under 60 years old (β=15.5, p=.004) and those with no comorbidities (β=16.0, p=.001) demonstrated better functional HRQoL. Being male was predictive of better functional HRQoL in the emotional (β=13.9, p<0.008), cognitive functioning (β=12.5, p=.013), role functioning (β=14.0, p=0.006) and physical functioning (β=17.8, p<0.001) domains.

CONCLUSIONS

Healthcare professionals in Oman should implement measures to enhance the HRQoL of CRC survivors, particularly women and those with coexisting morbidities.

Quality of life with encorafenib plus cetuximab with or without binimetinib treatment in patients with BRAF V600E-mutant metastatic colorectal cancer: patient-reported outcomes from BEACON CRC

Background

In the BEACON CRC study (NCT02928224), encorafenib plus cetuximab with binimetinib {9.3 versus 5.9 months; hazard ratio (HR) [95% confidence interval (CI)]: 0.60 [0.47-0.75]} or without binimetinib [9.3 versus 5.9 months; HR (95% CI): 0.61 (0.48-0.77)] significantly improved overall survival (OS) compared with the previous standard of care (control) in patients with BRAF V600E metastatic colorectal cancer (mCRC). Quality of life (QoL) was a secondary endpoint, assessed using validated instruments.

Patients and methods

BEACON CRC was a randomized, open-label, phase III study comparing encorafenib plus cetuximab with or without binimetinib and the investigator’s choice of irinotecan plus cetuximab or FOLFIRI plus cetuximab (chemotherapy control) in patients with previously treated BRAF V600E mCRC. Patient-reported QoL assessments included the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC) and Functional Assessment of Cancer Therapy—Colorectal (FACT-C). The primary outcome for these tools was time to definitive 10% deterioration.

Results

Encorafenib plus cetuximab, both with and without binimetinib, was associated with longer median times to definitive 10% deterioration versus the control group in the EORTC Global Health Status scale [HR (95% CI): 0.65 (0.52-0.80) versus 0.61 (0.49-0.75), respectively] and the FACT-C functional well-being subscale [HR (95% CI): 0.62 (0.50-0.76) versus 0.58 (0.47-0.72), respectively]. Consistent results were observed across all subscales of the EORTC and FACT-C instruments. QoL was generally maintained during treatment for the global EORTC and FACT-C scales.

Conclusions

In addition to improving OS, encorafenib plus cetuximab with or without binimetinib delays QoL decline in previously treated patients with BRAF V600E-mutant mCRC.

•

BEACON CRC compares encorafenib + cetuximab ± binimetinib to chemotherapy in previously treated BRAF V600E mCRC.

•

Encorafenib + cetuximab had longer time to 10% deterioration versus control in QoL and functional well-being scales.

•

Encorafenib + cetuximab ± binimetinib delays QoL decline in previously treated patients with BRAF V600E mCRC.

Hakami A. Assessment of Quality of Life (QoL) of Colorectal Cancer Patients using QLQ-30 and QLQ-CR 29 at King Abdulaziz Medical City, Jeddah, Saudi Arabia

Objective

We aimed to assess the quality of life (QoL) and its predictors in colorectal cancer (CRC) patients at King Abdulaziz Medical City, Jeddah.

Methods

A total of 118 CRC patients at King Abdulaziz Medical City, a tertiary hospital in Jeddah, participated in this study. The participants were provided with the online questionnaire via WhatsApp by trained researchers and data collectors in February 2021. All participants were required to answer the three-section questionnaire comprising of (a) demographic data and a validated Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaires, (b) a general version (QLQ-30), and (c) a CRC-specific version (QLQ-CR29).

Results

Statistical analysis revealed that the most common comorbidity among the participants was diabetes mellitus (42.4%). In addition, the mean global health status was 63.91 ± 24.75. For the global health tool QLQ-C30, results exhibited that physical functioning [62.94 (30.04)] and social functioning [63.56 (31.95)] scored below the threshold, while the cognitive functioning scale scored the highest [74.86 (25.11)]. In addition, on the QLQ-C30 scales, fatigue and insomnia were distressing, with fatigue scoring the highest. For the disease-specific tool QLQ-CR29, it was found that for the symptom scale, urinary frequency and embarrassment scored the highest. Conclusion. The participants reported high global quality of life on both the EORTC QLQ-30 and QLQ-CR29 scales. This study identifies the factors and predictors that affect the quality of life of CRC patients in Saudi Arabia. Recognizing these factors and predictors may empower those patients to maintain positive perception towards the impact of colorectal cancer and improve their survival.

Quality of Life as a Mediator between Cancer Stage and Long-Term Mortality in Nasopharyngeal Cancer Patients Treated with Intensity-Modulated Radiotherapy

Simple Summary

Even after the implementation of intensity-modulated radiotherapy (IMRT), nasopharyngeal cancer (NPC) survivors may continue to exhibit several physical symptoms that negatively affect long-term quality of life (QoL). An NPC patient cohort study (n = 682) was conducted to examine the potential mediating effect of QoL (evaluated at multiple treatment-related time points) on the cancer stage–mortality association. Patients with advanced NPC exhibited low global health QoL and high QoL-HN35 symptom pre-IMRT, 3 months post-IMRT, and 2 years post-IMRT. Global health QoL and QoL-HN35 symptom scores 2 years after IMRT explained 49.4% and 39.4% of the excessive effect of advanced NPC on mortality risk. Our findings indicate that global health QoL and QoL-HN35 symptom 2 years after IMRT are key mediators of the relationship between advanced NPC and high mortality. These findings emphasize the significance of QoL-HN35 symptom and global health QoL-associated medical support and care for patients with NPC who received IMRT.

Abstract

Background: Quality of life (QoL) attained before, during, or after treatments is recognized as a vital factor associated with therapeutic benefits in cancer patients. This nasopharyngeal cancer (NPC) patient longitudinal study assessed the relationship among QoL, cancer stage, and long-term mortality in patients with nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiotherapy (IMRT). Patients and Methods: The European Organization for Research and Treatment of Cancer (EORTC) core QoL questionnaire (QLQ-C30) and the head and neck cancer-specific QoL questionnaire module (QLQ-HN35) were employed to evaluate four-dimensional QoL outcomes at five time points: pre- (n = 682), during (around 40 Gy) (n = 675), 3 months (n = 640), 1 year (n = 578) and 2 years post-IMRT (n = 505), respectively, for 682 newly diagnosed NPC patients treated between 2003 and 2017 at a single institute. The median followed-up time was 7.5 years, ranging from 0.3 to 16.1 years. Generalized estimating equations, multivariable proportional hazards models, and Baron and Kenny’s method were used to assess the investigated effects. Results: Advanced AJCC stage (III–IV) patients revealed a 2.26-fold (95% CI—1.56 to 3.27) higher covariate-adjusted mortality risk than early-stage (I–II) patients. Compared with during IMRT, advanced-stage patients had a significantly low global health QoL and a significantly high QoL-HN35 symptom by a large magnitude at pre-, 3 months, and 2 years post-IMRT. QoL scales at pre-IMRT, 1 year, and 2 years post-IMRT were significantly associated with mortality. The effect changes of mortality risk explained by global health QoL, QoL-C30, and QoL-HN35 symptom were 5.8–9.8% at pre-IMRT but at 2 years post-IMRT were 39.4–49.4% by global health QoL and QoL-HN35 symptoms. Conclusions: We concluded advanced cancer stage correlates with a long-term high mortality in NPC patients treated with IMRT and the association is partially intermediated by QoL at pre-IMRT and 2 years post-IMRT. Therefore, QoL-HN35 symptom and global health QoL-dependent medical support and care should be focused and tailored at 2 years post-IMRT.

A Principal Component of Quality of Life Measures Is Associated with Survival for Head and Neck Cancer Patients Treated with Radiation Therapy

Simple Summary

Health-related quality of life (HRQOL) surveys describe the patient experience of disease and treatment. The relationship between post-treatment recovery of HRQOL and outcome in head and neck cancer is not well characterized. Impaired recovery of numerous individual components of HRQOL were associated with increased mortality. To obtain a better understanding how HRQOL (as a whole) impacts survival, we utilized a statistical technique called principal component analysis (PCA). PCA generated a total score of several HRQOL domains, named principal component 1 (PC1), to more accurately describe the cumulative impact of poor HRQOL recovery on outcome. PC1 was associated with survival and may be a useful tool in future studies to identify at-risk patients.

Abstract

Background: Health-related quality of life (HRQOL) metrics can be associated with survival in head and neck cancer (HNC); however, the impact of HRQOL recovery and the relevant HRQOL domains regarding outcome are unclear. Methods: Using a single-institution database, we retrospectively reviewed HNC patients treated with definitive or postoperative radiation therapy between 2013 and 2018. The recovery of individual HRQOL domains were determined by the ratio of the post-treatment to baseline scores. Univariate and Multivariate Cox regression were used to analyze survival outcomes. Principal component analysis was used to adjust for multicollinearity of HRQOL domains. Results: In 218 HNC patients who received radiation therapy, median follow-up was 24.8 months (interquartile range (IQR) 14.5–32.0). Principal component analysis evaluating the recovery of HRQOL domains revealed two independent principal components (PC), PC1 and PC2. PC1, which received contributions from the functional domains; physical (PF), role (RF), emotional (EF), cognitive (CF), and global health status (GQOL) was significantly associated with disease-free (HR = 0.77, 95% CI 0.61–0.98, p = 0.034) and overall survival (HR = 0.76, 95% CI 0.65–0.91, p = 0.004) on multivariate analysis and PC2, had no correlation with outcome and was mainly represented by social functioning. Unplanned hospitalization was significantly associated with lower PC1 scores (β = −0.997, Std. Error = 0.244, p < 0.001). Conclusion: Our study provides evidence that post-treatment recovery of HRQOL domains were associated with overall survival (OS) in HNC. PC1 is an attractive clinical tool to assess the recovery across multiple different HRQOL and the relationship with survival. Future prospective studies may identify patients who could benefit from additional rehabilitation based on PC1 score.

Differences in and Prognostic Value of Quality of Life Data in Rectal Cancer Patients with and without Distant Metastases

(1) Background: Individualization of treatment is a major challenge in oncology and requires a variety of predictive and prognostic parameters. In addition to tumor biology analyses, baseline health-related quality of life might be a valid tool to predict overall survival. This study was conducted to evaluate the prognostic relevance of baseline quality of life data in patients with rectal cancer. In this context, differences between patients with and without distant metastases were of particular interest. (2) Methods: Our cohort included 258 patients with rectal cancer treated in the radiotherapy department of the University Hospital Erlangen. Patients completed the European Organisation for Research and Treatment of Cancer (EORTC) core quality of life questionnaire (QLQ C30) and colorectal cancer questionnaire (CR38). Clinical and survival data were provided by the Gießener Tumor Documentation System (GTDS) of the Comprehensive Cancer Center Erlangen-EMN (CCC, Friedrich-Alexander University Erlangen-Nuremberg, Erlangen, Germany). Statistical analyses were performed using Kaplan–Meier analyses and univariate and multivariate Cox regression. (3) Results: A cohort of 258 patients with rectal adenocarcinoma was analyzed including 50 patients (19.4%) with metastatic disease. No differences were observed between patients with and without distant metastases in most areas of quality of life studied, with the exception of physical function, loss of appetite, chemotherapy side effects and weight loss. Gender, baseline physical function, sexual function, diarrhea, and weight loss over time had a prognostic value in the entire cohort. Appetite loss was an additional prognostic parameter in patients with distant metastases. (4) Conclusions: The quality of life of patients with metastatic disease differed only slightly from non-metastatic patients. Health-related quality of life data provide prognostic information for patients with rectal cancer.

Highlighting the Potential for Chronic Stress to Minimize Therapeutic Responses to Radiotherapy through Increased Immunosuppression and Radiation Resistance

Ionizing radiation has been used in the treatment of cancer for more than 100 years. While often very effective, there is still a great effort in place to improve the efficacy of radiation therapy for controlling the progression and recurrence of tumors. Recent research has revealed the close interaction between nerves and tumor progression, especially nerves of the autonomic nervous system that are activated by a variety of stressful stimuli including anxiety, pain, sleep loss or depression, each of which is likely to be increased in cancer patients. A growing literature now points to a negative effect of chronic stressful stimuli in tumor progression. In this review article, we present data on the potential for adrenergic stress to influence the efficacy of radiation and in particular, its potential to influence the anti-tumor immune response, and the frequency of an "abscopal effect" or the shrinkage of tumors which are outside an irradiated field. We conclude that chronic stress can be a major impediment to more effective radiation therapy through mechanisms involving immunosuppression and increased resistance to radiation-induced tumor cell death. Overall, these data highlight the potential value of stress reduction strategies to improve the outcome of radiation therapy. At the same time, objective biomarkers that can accurately and objectively reflect the degree of stress in patients over prolonged periods of time, and whether it is influencing immunosuppression and radiation resistance, are also critically needed.

Deterioration of Health-Related Quality of Life Scores under Treatment Predicts Longer Survival

Objectives

Baseline health-related quality of life (HRQoL) scores predict survival, which has already been demonstrated in various studies. However, we were interested in whether changes in baseline scores during treatment are also significant predictors of survival.

Methods and Materials

We analysed the data of 400 consecutive cancer patients receiving radiochemotherapy. Leading diagnoses were head and neck cancer (34.5%), rectal cancer (24.5%), and lung cancer (13%). HRQoL was studied at baseline, six weeks after therapy and after each completed year after the start of therapy until drop out of the study using the EORTC QLQ-C30 questionnaire. The change score was calculated as the baseline score subtracted from the score after therapy. Statistics included Kaplan-Meier estimates and Cox regression.

Results

High global health status (p = 0.005) and low pain scores (p = 0.040) at baseline were related to favourable overall survival. Change scores of role functioning (p = 0.027), global health status (p < 0.018), and pain (p < 0.001) were predictive of overall survival. Pain was the superior predictor of survival (p = 0.001) among all variables and QoL scores studied by multivariate analysis. A deterioration in pain was associated with a 2.8 times higher chance of survival (HR 0.36).

Conclusions

Deterioration of HRQoL baseline pain score by cancer treatment is a favourable and superior prognostic factor for survival.

Patterns of racial/ethnic disparities in baseline health-related quality of life and relationship with overall survival in patients with colorectal cancer

PURPOSE

Racial disparities are evident in colorectal cancer (CRC) prognosis with black patients experiencing worse outcomes than Hispanics and whites, yet mediators of these disparities are not fully known. The aim of this study is to identify variables that contribute to racial/ethnic disparities in health-related quality of life (HR-QoL) and overall survival in CRC.

METHODS

Using SF-12 questionnaires, we assessed HR-QoL in 1132 CRC patients by calculating their physical (PCS) and mental composite summary (MCS) scores. Associations between poor PCS/MCS and sociodemographic factors were estimated and survival differences were identified by race/ethnicity.

RESULTS

Hispanic patients who never married were at greater risk of poor PCS (OR 2.69; 95% CI 1.11-6.49; P = 0.028) than were currently married patients. College education was associated with a decreased risk of poor PCS in Hispanic and white, but not black, patients. Gender was significantly associated with poor MCS among white patients only. CRC patients who reported a poor PCS or MCS had poor survival, with differences in median survival times (MSTs) by race. The effect of PCS was strongest in white CRC patients with a difference in overall MST of > 116 months between those with favorable versus poor physical HR-QoL. Black patients who reported poor Physical and Mental HR-QoL showed significant risk of a poor outcome.

CONCLUSION

These findings suggest that racial/ethnic disparities in CRC survival may be related to differences in HR-QoL. Identified mediators of HR-QoL could supplement current CRC management strategies to improve patients' survival.

Improvements in Clinical Outcomes for BRAFV600E -Mutant Metastatic Colorectal Cancer

Although the last two decades have seen a broad improvement in overall survival, colorectal cancer is still the second leading cause of cancer deaths worldwide. Patient populations continue to face poor disease prognoses due to the challenges of early detection and the molecular subtypes driving their colorectal cancer. Consequently, many patients present with metastatic colorectal cancer, which often limits options and shifts treatment focus away from curative interventions. BRAF^V600E mutations are present in approximately 10% of colorectal cancer tumors and are associated with uninhibited cell proliferation, reduced apoptosis, and resistance to standard therapeutic options. In colorectal cancer, BRAF^V600E mutations are associated with decreased overall survival, poor treatment responses, and different patterns of metastatic spread compared with tumors with wild-type BRAF Success in treating other BRAF^V600E -mutant cancers with BRAF inhibitors as monotherapy has not translated into efficacious treatment of metastatic colorectal cancer. Consequently, combination therapy with inhibitors of BRAF, MEK, and EGFR, which overcomes the innate treatment-resistant characteristics of BRAF ^V600E-mutant colorectal cancer, is now recommended by treatment guidelines.

Reducing Patient Burden and Improving Data Quality With the New Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire

BACKGROUND

The Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire was developed in response to the need for a new, fast, and comprehensive tool for evaluating quality of life in patients who have colorectal cancer. Available surveys such as the SF-12, SF-36, Functional Assessment of Cancer Therapy-Colorectal, and European Organization for Research and Treatment of Cancer are either too general to be informative or too lengthy to complete.

OBJECTIVE

The aim was to validate the Cleveland Clinic Foundation Colorectal Quality of Life Questionnaire.

DESIGN

Data were obtained as part of a prospective randomized controlled trial.

SETTINGS

This was a worldwide multicenter study with 2 domestic and 5 international locations.

PATIENTS

This study randomly assigned 190 patients between the ages of 18 and 80 undergoing surgery for low rectal cancer. Of those randomly assigned, 142 with partially complete surveys were analyzed for selection bias and acceptability, and 95 with complete surveys were analyzed for survey validity.

INTERVENTIONS

Patients received either a J-pouch, side-to-end anastomosis, or straight anastomosis.

MAIN OUTCOME MEASURE

The study evaluated survey validity measures such as standardized Cronbach α for internal consistency and Spearman correlation coefficients for construct validity, convergent validity, and responsiveness. Univariate analyses were used to assess discriminative validity.

RESULTS

Sufficient acceptability, construct, and convergent validity and responsiveness were achieved. All scores showed great internal consistency (Cronbach α >0.8). Superior discriminative ability was demonstrated by significant differences (p < 0.05) in 2 of 7 scores between neoadjuvant treatment groups, and in 6 of 7 scores between complication groups, none of which were detected by the SF-12 or Functional Assessment of Cancer Therapy-Colorectal surveys.

LIMITATIONS

Limitations included a small sample size, cultural differences, and failure to assess test-retest ability of the questionnaire.

CONCLUSIONS

The Cleveland Clinic Colorectal Cancer Quality of Life Questionnaire is an efficient and reliable quality-of-life measure that better incorporates factors specific to colorectal cancer surgery.

Patient-reported symptom burden as a prognostic factor in treatment with first-line cetuximab plus chemotherapy for unresectable metastatic colorectal cancer: Results of Phase II QUACK trial

Background

It remains unclear whether patients’ self‐perceptions of symptoms at baseline clinically impact the prognostic relevance, treatment efficacy, or toxicity profiles in metastatic colorectal cancer (mCRC) patients treated with the first‐line cetuximab and standard chemotherapy.

Methods

The data were collected from a prospective trial that assessed the relationships between quality of life (QOL), treatment efficacy, and adverse events (AEs).

Results

The analysis of 137 mCRC patients revealed a significant association between the presence of baseline tumor‐related symptoms and a lower overall survival (OS) compared to the absence of symptoms (HR, 2.49; 95% CI, 1.37‐4.62; P = .003). The asymptomatic responders had favorable outcomes compared to the symptomatic nonresponders (2‐year OS rates: 83.6% and 35.9%, respectively), while the symptomatic responders had similar outcomes to the asymptomatic nonresponders. The median postprogression survival differed significantly: 10.2 months for the symptomatic patients and 15.9 months for the asymptomatic patients (HR, 2.29; 95% CI, 1.25‐4.29, P = .008). The objective response rates and patient toxicity profiles were similar irrespective of the severity of baseline symptoms.

Conclusion

Baseline symptoms were associated with worse OS but not with impaired treatment efficacy or more frequent AEs in mCRC patients treated with cetuximab in addition to chemotherapy.

Factors related to the quality of life in liver cancer patients during treatment phase: A follow-up study

OBJECTIVE

This study aims to explore the predictive value of demographic and clinical factors in changes in quality of life (QoL) in liver cancer (LC) patients over time.

METHODS

We performed a prospective cohort study in 128 patients who had 4 time point data newly diagnosed with LC at two hospitals in Taiwan. Different functional QoL was measured by QLQ-C30. Specific characteristics were predictors for distinct functional QoL, estimated by a generalised estimating equation (GEE).

RESULTS

Patients who received liver resection or radiofrequency ablation therapy (RFA) versus transarterial chemoembolisation (TACE) or transcatheter arterial embolisation (TAE) experienced a decrease in physical function from baseline to 1 month. In addition, patients who underwent liver resection versus RFA experienced a significant recovery in cognitive functioning from baseline to 6 months. Patients with advanced stage compared to those in early stage had a reduction in physical functioning from baseline to 1 month. The alcohol intake, hepatitis C infection and the job also affected the changes in physical and cognitive functioning.

CONCLUSION

Healthcare professionals should pay attention to changes after treatment in the short term; additionally, they need to provide health education to modifiable factors such as alcohol intake attributed to the deterioration in QoL.

Consensus and controversies regarding follow-up after treatment with curative intent of nonmetastatic colorectal cancer: a synopsis of guidelines used in countries represented in the European Society of Coloproctology

AIM

It is common clinical practice to follow patients for a period of years after treatment with curative intent of nonmetastatic colorectal cancer, but follow-up strategies vary widely. The aim of this systematic review was to provide an overview of recommendations on this topic in guidelines from member countries of the European Society of Coloproctology, with supporting evidence.

METHOD

A systematic search of Medline, Embase and the guideline databases Trip database, BMJ Best Practice and Guidelines International Network was performed. Quality assessment included use of the AGREE-II tool. All topics with recommendations from included guidelines were identified and categorized. For each subtopic, a conclusion was made followed by the degree of consensus and the highest level of evidence.

RESULTS

Twenty-one guidelines were included. The majority recommended that structured follow-up should be offered, except for patients in whom treatment of recurrence would be inappropriate. It was generally agreed that clinical visits, measurement of carcinoembryoinc antigen and liver imaging should be part of follow-up, based on a high level of evidence, although the frequency is controversial. There was also consensus on imaging of the chest and pelvis in rectal cancer, as well as endoscopy, based on lower levels of evidence and with a level of intensity that was contradictory.

CONCLUSION

In available guidelines, multimodal follow-up after treatment with curative intent of colorectal cancer is widely recommended, but the exact content and intensity are highly controversial. International agreement on the optimal follow-up schedule is unlikely to be achieved on current evidence, and further research should refocus on individualized 'patient-driven' follow-up and new biomarkers.

Validation of Quality of Life Instruments for Cancer Patients - Colorectal Cancer (QLICP-CR) in patients with colorectal cancer in Northeast China

BACKGROUND

Measuring quality of life is important for cancer patients, but there are regional differences in age-standardized colorectal cancer incidence and mortality rates which may affect measurement. This study aimed to evaluate the reliability, validity and responsiveness of Quality of Life Instruments for Cancer Patients - Colorectal Cancer (QLICP-CR) in colorectal cancer patients in Northeast China, and assess its usefulness for evaluation of quality of life in these patients.

METHODS

From November 2016 to January 2017, 152 patients with colorectal cancer from Liaoning Cancer Hospital & Institute were surveyed three times using QLICP-CR and the Functional Assessment of Cancer Therapy - Colorectal (FACT-C) to measure their quality of life (on admission, 2-3 days later and at discharge). Reliability was evaluated by internal consistency and test-retest reliability. Validity was examined by item-domain correlation, criterion-related validity and factor construct validity analysis. Responsiveness was assessed using paired Student's t tests and calculating standardized response mean.

RESULTS

Cronbach's α coefficient for QLICP-CR ranged from 0.62 to 0.93. Pearson correlation and intra-class correlation coefficients for QLICP-GM, the five domains and the total scale of QLICP-CR ranged from 0.74 to 0.91 and 0.74 to 0.90. The item-domain correlation analysis showed good convergent validity and discriminant validity. Correlation analysis of domain scores between FACT-C and QLICP-CR showed good criterion-related validity. Exploratory factor analysis revealed that nine and three principal components were extracted from items in the two modules of QLICP-CR, and the contribution rate of cumulative variance was 70.21 and 72.26%. There were significant differences in quality of life between the first and the third measurements, with standardized response mean values ranging from 0.30 to 0.81.

CONCLUSIONS

The QLICP-CR was a reliable, valid and sensitive instrument to measure quality of life in colorectal cancer patients in Northeast China.

Health-related quality of life in long-term survivors of colorectal cancer and its association with all-cause mortality: a German cohort study

Background

The group of colorectal cancer (CRC) survivors continues to grow worldwide. Understanding health-related quality of life (HRQOL) determinants and consequences of HRQOL impairments in long-term CRC survivors may help to individualize survivorship care plans. We aimed to i) examine the HRQOL status of CRC long-term survivors, ii) identify cross-sectional sociodemographic and clinical correlates of HRQOL, and iii) investigate the prospective association of HRQOL after CRC diagnosis with all-cause mortality.

Methods

We assessed HRQOL within a Northern German cohort of 1294 CRC survivors at a median of 6 years after CRC diagnosis using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). Cross-sectional correlates of different HRQOL dimensions were analyzed using multivariable-adjusted logistic regression models with HRQOL as a binary variable. With multivariable-adjusted Cox proportional hazards regression models, hazard ratios (HR) of all-cause mortality were estimated per 10-point-increments of an HRQOL summary score, a global quality of life scale, and HRQOL functioning and symptom domains.

Results

The median HRQOL summary score was 87 (interquartile range: 75–94). Sex, age, education, tumor location, metastases, other cancers, type of therapy, and current stoma were identified as correlates of different HRQOL scales. After a median follow-up time of 7 years after HRQOL assessment, 175 participants had died. Nearly all HRQOL domains, except for cognitive functioning and diarrhea, were significantly associated with all-cause mortality. A 10-point-increment in the summary score decreased the risk of death by 24% (HR: 0.76; 95% CI: 0.70–0.82).

Conclusions

HRQOL in CRC survivors appeared to be relatively high in the long term. Various clinical and sociodemographic factors were cross-sectionally associated with HRQOL in long-term CRC survivors. Lower HRQOL was associated with increased all-cause mortality. Individualized healthcare programs for CRC survivors (including psychosocial screening and interventions) are needed to detect decreased HRQOL and to further improve long-term HRQOL and survival.

Evaluation of the Impact of Cancer Treatment on the Adoption and Consolidation of Pro-Health Attitudes in the Field of Cancer in Treated Patients with Colon Cancer

Colorectal cancer is the second most common cause of cancer deaths worldwide. Although progress in the development of new drugs over the last two decades has expanded treatment options for this disease, many significant problems relating to their optimization remain to be solved. Data on the cancer knowledge and the healthy behavior and lifestyle in patients with colorectal cancer in Poland is missing. We analyzed the course and results of treatment of first-line chemotherapy in 165 patients diagnosed with colorectal cancer treated between May 2010 and December 2013. The respondent's knowledge in the field of cancer and their lifestyle before and after the treatment were rated. The results were compared with a control group. Mean age was 60.89 ± 8.69 years, median 59 years. The general knowledge about cancer and the level of healthy lifestyle before treatment were low. After treatment, both the knowledge about cancer and the level of healthy lifestyle increased compared to the control group. There was a clear relationship between the level of knowledge about cancer and the willingness to adopt attitudes and healthy behavior by patients. In our analysis, the overall quality of life in patients treated with first-line palliative chemotherapy of colorectal cancer did not change during treatment. Our results indicate the need to implement an educational program on cancer prevention in treated patients, and the analysis of quality of life and other factors than treatment effect remains controversial.

Moving Beyond Conventional Clinical Trial End Points in Treatment-refractory Metastatic Colorectal Cancer: A Composite Quality-of-life and Symptom Control End Point

PURPOSE

This review highlights the evidence supporting symptom control and quality-of-life (QOL) measures as predictors of survival in treatment-refractory metastatic colorectal cancer (mCRC) and describes a composite symptom control and QOL end point recently reported in a Phase III trial that may serve as a more reasonable end point of efficacy in this population.

METHODS

A literature search was conducted using MEDLINE to identify clinical studies (including case series and observational, retrospective, and prospective studies) that reported the predictive value of QOL measures for survival in mCRC. The search was limited by the following key words: quality of life, survival, and colorectal cancer. We then performed a second search limited to studies of randomized and Phase III design in mCRC to identify studies that used QOL assessments as their primary end points. A manual search was also performed to include additional studies of potential relevance.

FINDINGS

There is increasing evidence to support that symptom control and QOL measures are predictors of survival in treatment-refractory mCRC and can serve as an alternative but equally as important end point to survival in this population. A recent large, randomized Phase III trial using a composite primary end point of lean body mass, pain, anorexia, and fatigue reported the feasibility in evaluating benefit in mCRC beyond conventional clinical trial end points.

IMPLICATIONS

Future studies in treatment-refractory mCRC may be better served by evaluating improvement in symptom control and QOL, which may otherwise serve as the best predictor of survival in last-line treatment settings.

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.

Improving Outcomes in Patients with CRC: The Role of Patient Reported Outcomes-An ESDO Report

Colorectal cancer is one of the most commonly diagnosed cancers worldwide and nearly half of patients will develop metastatic disease at some point during the course of their disease. The goal of anticancer therapy in this context is to extend survival, while trying to maximise the patient’s health-related quality of life. To this end, we need to understand how to incorporate patient-reported outcomes into clinical trials and routine practice to accurately assess if treatment strategies are providing clinical benefit for the patient. This review reflects the proceedings of a 2016 European Society of Digestive Oncology workshop, where the authors discussed the use of patient-reported outcomes to measure health-related quality of life when evaluating treatment during the management of colorectal cancer. A summary of the challenges associated with implementing patient-reported outcomes in clinical trials is provided, as well as a review of the current clinical evidence surrounding patient-reported outcomes in metastatic colorectal cancer.

The utility of abbreviated patient-reported outcomes for predicting survival in early stage colorectal cancer

BACKGROUND

Patient-reported outcomes (PROs) are increasingly used in clinical settings. Prior research suggests that PROs collected at baseline may be associated with cancer survival, but most of those studies were conducted in patients with breast or lung cancer. The objective of this study was to determine the correlation between prospectively collected PROs and cancer-specific outcomes in patients with early stage colorectal cancer.

METHODS

Patients who had newly diagnosed stage II or III colorectal cancer from 2009 to 2010 and had a consultation at the British Columbia Cancer Agency completed the brief Psychosocial Screen for Cancer (PSSCAN) questionnaire, which collects data on patients' perceived social supports, quality of life (QOL), anxiety and depression, and general health. PROs from the PSSCAN were linked with the Gastrointestinal Cancers Outcomes Database, which contains information on patient and tumor characteristics, treatment details, and cancer outcomes. Cox regression models were constructed for overall survival (OS), and Fine and Gray regression models were developed for disease-specific survival (DSS).

RESULTS

In total, 692 patients were included. The median patient age was 67 years (range, 26-95 years), and the majority had colon cancer (61%), were diagnosed with stage III disease (54%), and received chemotherapy (58%). In general, patients felt well supported and reported good overall health and QOL. On multivariate analysis, increased fatigue was associated with worse OS (hazard ratio [HR], 1.99; P = .00007) and DSS (HR, 1.63; P = .03), as was lack of emotional support (OS: HR, 4.36; P = .0003; DSS: HR, 1.92; P = .02).

CONCLUSIONS

Although most patients described good overall health and QOL and indicated that they were generally well supported, patients who experienced more pronounced fatigue or lacked emotional support had a higher likelihood of worse OS and DSS. These findings suggest that abbreviated PROs can inform and assist clinicians to identify patients who have a worse prognosis and may need more vigilant follow-up.

The Relationship Between Health-Related Quality of Life and Survival in Metastatic Colorectal Cancer Patients Treated With Korean Medicine

OBJECTIVES

This study aimed to identify the relationship between health-related quality of life (HRQoL) measured by the Functional Assessment Cancer Therapy-General (FACT-G) and survival in metastatic colorectal cancer (mCRC) patients.

METHODS

The clinical characteristics and FACT-G scores were retrospectively reviewed in mCRC patients who visited the Cancer Center of Korean Medicine. The overall survival (OS) was calculated and compared using the Kaplan-Meier method and log-rank test. Univariate and multivariate Cox regression analyses were performed based on clinical characteristics and FACT-G scores. To identify significant differences in answer frequency, χ² tests and Fisher's exact tests were used.

RESULTS

A total of 58 patients were reviewed. The proportion of patients who had an Eastern Cooperative Oncology Group-Performance Status ≥ 2 was 43.1%, multiple distant metastatic sites was 77.6%, liver metastases was 43.1%, been previously treated was 89.7%, and received more than the second-line chemotherapy was 75.5%. The mean total FACT-G score was 65.3 (median 65.6). The median OS was 7 months. There was no significant difference in OS between the 2 groups divided by the median values of FACT-G total and subscores. In univariate analyses, functional well-being (FWB) score had a significant impact on survival. In multivariate analyses, presence of liver metastasis, FACT-G total score, and FWB score were significant prognostic predictors of survival. No statistically different answer frequency was observed for any question regarding FWB.

CONCLUSIONS

This study found that FACT-G total and FWB scores were potential prognostic factors for predicting OS in relapsed or refractory mCRC patients treated with Korean Medicine.

Longitudinal alterations in health-related quality of life and its impact on the clinical course of patients with advanced hepatocellular carcinoma receiving sorafenib treatment

Background

This study aimed to identify the health-related quality of life (HRQOL) domains associated with prognosis by assessing longitudinal alterations in HRQOL in patients with advanced hepatocellular carcinoma receiving sorafenib.

Methods

We prospectively assessed HRQOL by administering the SF-36 questionnaire 3-monthly to consecutive patients with advanced hepatocellular carcinoma receiving sorafenib. We evaluated the impact of HRQOL on their overall survival and duration of treatment with sorafenib using Cox's proportional hazards model.

Results

There were 54 participants: 42 (78 %) were male, the median age was 71 years, 24 (44 %) had hepatitis C virus infection, 33 (61 %) had Child-Pugh scores of 5, and 30 (56 %) had TNM stage IV hepatocellular carcinoma. The median overall survival and treatment duration were 9 and 5 months, respectively, and 40 patients (74 %) died. Thirteen patients receiving sorafenib over a 1-year period maintained all domain scores >40, without a significant decline during the treatment period. In contrast, physical functioning, physical role, and vitality scores declined continuously and significantly in the year before death (in the 40 patients who died). Previous curative treatment and physical functioning scores ≥40 at baseline were significantly associated with longer overall survival by multivariate analysis. Social functioning scores ≥40, absence of vascular invasion, and lower DCP value were significant predictors of longer treatment duration.

Conclusions

HRQOL was not significantly impaired in those patients who were able to complete a 1-year course of sorafenib treatment. Baseline physical functioning scores ≥40 and social functioning scores ≥40 were significantly associated with longer overall survival and longer treatment duration, respectively. Thus, HRQOL could be a valuable marker to predict the clinical course of patients with advanced hepatocellular carcinoma receiving sorafenib.

Quality of life of early stage colorectal cancer patients in Morocco

Background

A multicentre cohort study was held in Morocco, designed to evaluate the quality of life of cancer patients. The aim of this paper is to report the assessment of the quality of life of early colorectal cancer patients, before and after cancer treatment, to identify other factors which are related to this quality of life.

Methods

We used the third version of the QLQ-C30 questionnaire of the European organization for Research and treatment of Cancer (EORTC) after a transcultural validation. The Data collection was done at inclusion and then every twelve weeks to achieve one year of follow up.

Results

Overall 294 patients presented with early colorectal cancer, the median age was 56 years (range: 21–88). The male–female sex ratio was 1.17. At inclusion, the global health status was the most affected functional dimension. For symptoms: financial difficulties and fatigue scores were the highest ones. Emotional and social functions were significantly worse in rectal cancer. Most symptoms were more present in rectal cancer. At inclusion, global health status score was significantly worse in stage III. Anorexia was significantly more important among colorectal female patients. For Patients over 70 years-old, the difference was statistically significant for the physical function item which was lower. Overall, Functional dimensions scores were improved after chemotherapy. The symptoms scores did not differ significantly for patients treated by radiotherapy, between inclusion and at one year.

Conclusion

Our EORTC QLQ C30 scores are overall comparable to the reference values. Neither chemotherapy, nor radiotherapy worsened the quality of life at one year.

Prognostic value of health-related quality of life in patients with metastatic pancreatic adenocarcinoma: a random forest methodology

PURPOSE

Eastern Cooperative Oncology Group Performance Status (ECOG-PS) is currently an important parameter in the choice of treatment strategy for metastatic pancreatic adenocarcinoma (mPA) patients. However, previous research has shown that patients' self-reported health-related quality of life (HRQOL) scales provided additional prognostic information in homogeneous groups of patients with respect to ECOG-PS. The aim of this study was to identify HRQOL scales with independent prognostic value in mPA and to propose prognostic groups for these patients.

METHODS

We analysed data from 98 chemotherapy-naive patients with histologically proven mPA recruited from 2007 to 2011 in the FIRGEM phase II study which aimed to compare the effectiveness of two chemotherapy regimen. HRQOL data were assessed with the European Organization for Research and Treatment of Cancer QLQ-C30 questionnaire. A random survival forest methodology was used to impute missing data and to identify major prognostic factors for overall survival.

RESULTS

Baseline HRQOL assessment was completed by 60 % of patients (59/98). Twelve prognostic variables were identified. The three most important prognostic variables were fatigue, appetite loss, and role functioning, followed by three laboratory variables. The model's discriminative power assessed by Harrell's C statistic was 0.65. Fatigue score explained almost all the survival variability.

CONCLUSION

HRQOL scores have prognostic value for mPA patients with good ECOG-PS. Moreover, the patient's fatigue, appetite loss, and self-perception of daily activities were more reliable prognostic indicators than clinical and laboratory variables. These HRQOL scores, especially the fatigue symptom, should be urgently included for prognostic assessment of mPA patients (with good ECOG-PS).

Quality of life and satisfaction with care among palliative cancer patients in Saudi Arabia

OBJECTIVE

This study aimed to determine the relationship between quality of life and satisfaction with care among cancer patients in palliative care in Saudi Arabia.

METHODS

A total of 130 palliative cancer patients were invited to participate in our cross-sectional study. Patients were recruited from a large tertiary hospital within the Ministry of Health in Saudi Arabia. All eligible participants answered a three-part questionnaire that included demographic data and the validated European Organization for Research and Treatment of Cancer (EORTC QLQ-C15-PAL) and (EORTC IN-PATSAT32) questionnaires.

RESULTS

Participants were mostly female (103/130, 79%) and married (93/130, 71%), and more than half had breast cancer (69/130, 53%). They were between 17 and 86 years of age (mean = 46.7, SD = 16.50). The correlation test showed that the relationship with physical function was weak, while emotional function and global health status had a moderate relationship with general satisfaction (r = 0.21, p < 0.01; r = 0.32, p < 0.001; r = 0.26, p < 0.01, respectively). Our results suggest that emotional function is the more important factor in predicting satisfaction with care among palliative cancer patients. An increase in emotional function leads to increased general satisfaction.

SIGNIFICANCE OF RESULTS

The emotional function of palliative cancer patients was more closely associated with overall satisfaction with care than physical function or global health status. All palliative care team members are thus required to provide adequate psychosocial support. It is recommended that interdisciplinary and collaborative approaches be integrated in palliative care of cancer patients.

Prognostic value of health-related quality of life for death risk stratification in patients with unresectable glioblastoma

Glioblastoma is the most common malignant brain tumor in adults. Baseline health‐related quality of life (HRQoL) is a major subject of concern for these patients. We aimed to assess the independent prognostic value of HRQoL in unresectable glioblastoma (UGB) patients for death risk stratification. One hundred and thirty‐four patients with UGB were enrolled from the TEMAVIR trial. HRQoL was evaluated at baseline using the EORTC QLQ‐C30 and BN20 brain cancer module. Clinical and HRQoL parameters were evaluated in univariable and multivariable Cox analysis as prognostic factors for overall survival (OS). Performance assessment and internal validation of the final model were evaluated with Harrel's C‐index, calibration plot, and bootstrap sample procedure. Two OS independent predictors were identified: future uncertainty and sensitivity deficit. The final model exhibited good calibration and acceptable discrimination (C statistic = 0.63). The internal validity of the model was verified with robust uncertainties around the hazard ratio. The prognostic score identified three groups of patients with distinctly different risk profiles with median OS estimated at 16.2, 9.2, and 4.5 months. We demonstrated the additional prognostic value of HRQoL in UGB for death risk stratification and provided a score that may help to guide clinical management and stratification in future clinical trials.

Health-related quality of life is a prognostic factor for survival in older patients after colorectal cancer diagnosis: A population-based study

BACKGROUND

Studies carried out in the context of clinical trials have shown a relationship between survival and health-related quality of life in colorectal cancer patients.

AIMS

We assessed the prognostic value of health-related quality of life at diagnosis and of its longitudinal evolution on survival in older colorectal cancer patients.

METHODS

All patients aged ≥65 years, diagnosed with new colorectal cancer between 2003 and 2005 and registered in the Digestive Cancer Registry of Burgundy were eligible. Patients were asked to complete the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at inclusion, three, six and twelve months after. Multivariate regression models were used to evaluate the prognostic value of health-related quality of life scores at diagnosis and their deterioration on relative survival.

RESULTS

In multivariate analysis, a role functioning dimension lower than median was predictive of lower survival (hazard ratio=3.1, p=0.015). After three and six months of follow-up, patients with greater appetite loss were more likely to die, with hazard ratios of 4.7 (p=0.013) and 3.7 (p=0.002), respectively.

CONCLUSIONS

Health-related quality of life assessments at diagnosis are independently associated with older colorectal cancer patients' survival. Its preservation should be a major management goal for older cancer patients.

A cross-sectional assessment of quality of life of colorectal cancer patients in Saudi Arabia

OBJECTIVE

In this cross-sectional study, we aimed to describe the quality of life of Saudi colorectal cancer (CRC) patients and identify the factors that may further improve health care for CRC survivors in Saudi Arabia (KSA).

METHODS

A total of 106 CRC patients from five different private and public tertiary level hospitals in Saudi Arabia participated in this study. CRC patient was interviewed by a trained researcher between September and December 2014. All respondents answered a three-part questionnaire which includes demographic data and a validated Arabic version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life.

RESULTS

Participants had a mean score for global health of 67.1 (95 % CI 62.55-71.71). Among the five scales of quality of life, social functioning and functional scales of CRC patients scored the highest [Mean 83.49 (95 % CI 78.64-86.33)] while the lowest scored was emotional scales [66.9 (95 % CI 61.81-71.98)]. Insomnia was considered the most distressing symptom on the symptom scales. Using the disease-specific tool, it was found that sexual interest scored the highest. On the symptom scale, dissatisfaction with stoma care problems scored the highest.

CONCLUSION

Factors associated with a major reduction in all domains of quality of life included employment status and tumor location. This study identifies the factors and issues that affect the quality of life of CRC patients in KSA. Addressing these factors and issues may lessen the burden of cancer survivors in the KSA or may prolong their survival.

The longitudinal relationship between quality of life and survival in advanced stage cancer

OBJECTIVES

Quality of Life (QoL) at baseline is frequently found to be a prognostic factor in cancer studies. However, little is known about the relationship of the trajectory of QoL and survival in patients with advanced cancer. This study evaluates the effects of both level and change of QoL on survival to explore the potential of utilizing longitudinal information of QoL for prognosis.

METHODS

A series of joint models were used in a sample (N = 512) of patients diagnosed with advanced cancer (sample consisted of nine different cancer sites) with assessments of QoL across six time points and with survival information recorded up to 28 months after diagnosis. We used FACT-G as the QoL measure, and we evaluated the effects of change in QoL controlling for the time-dependent effects of chemotherapy and radiation.

RESULTS

The median survival for patients was 14.2 months, and 10% of the sample had survived beyond 28 months after the diagnosis of advanced cancer. The effect of change of QoL on survival was significant (hazard ratio = 0.98; p < 0.001) controlling for time-dependent treatment effects. Also, the slope of the trajectory in QoL was found to be a significant predictor of survival (hazard ratio = 0.18; p < 0.001).

CONCLUSION

These preliminary findings suggest that the patient's longitudinal experience in QoL may be a significant prognostic factor of survival, a novel finding with potentially important implications in medical decision making. Longitudinal information on QoL can be used for updating the patient's prognosis of survival.

MS-20, a chemotherapeutical adjuvant, reduces chemo-associated fatigue and appetite loss in cancer patients

A small pilot study of the fermented soybean extract MicrSoy-20(MS-20) demonstrated its ability to restore chemotherapy-induced immunosuppression and improve quality of life (QoL). This randomized, cross-over, comparative trial was conducted to confirm the effects of MS-20 on QoL and to understand its underlying mechanism when used in conjunction with chemotherapy. One hundred forty-three patients undergoing cancer chemotherapy were randomly assigned to 2 groups. Group 1 was administered MS-20 for 1 wk followed by 3 wk of concomitant MS-20 plus chemotherapy. Group 2 was administered chemotherapy for 3 wk. QoL was assessed by the EORTC/QLQ-C30 questionnaire and visual analogue scales (VAS). Changes in immunological parameters and antioxidant profiles were also examined. Significant increases were observed in EORTC/QLQ-C30 scores for physical (4.45, P = 0.023) and social (3.99, P = 0.023) functioning in Group 1 patients compared to Group 2 patients. VAS scores for fatigue and appetite loss significantly improved with MS-20 treatment (P < 0.001). Group 1 patients exhibited smaller decreases in peripheral blood mononuclear cells compared to Group 2 patients (P = 0.026). Other immunological parameters, antioxidant, and safety profiles were not significantly different between treatment groups. Addition of MS-20 as an adjuvant to chemotherapy can be effective in improving QoL for cancer patients.

Health-related quality of life and risk of colorectal cancer recurrence and All-cause death among advanced stages of colorectal cancer 1-year after diagnosis

Background

The study aimed to examine the association between health-related quality of life (HRQOL) assessed with overall survival (OS) and recurrence after diagnosis of colorectal cancer (CRC).

Methods

Overall 160 patients with advanced stage CRC were recruited in an observational study and completed the generic and condition-specific HRQOL questionnaires at the colorectal specialist outpatient clinic in Hong Kong, between 10/2009 and 07/2010. Socio-demographic and clinical characteristics including duration since diagnosis, primary tumor location and treatment modality, were collected to serve as predictor variables in regression models. All-cause death or CRC recurrence was the event of interest. Association between HRQOL with OS was assessed using Cox regression. Association between HRQOL and CRC recurrence was further modeled by competing-risks regression adjusted for the competing-risks of death from any cause.

Results

After a median follow-up of 23 months, there were 22 (16.1%) incidents of CRC recurrence and 15 (9.4%) deaths. Decreased physical functioning (hazard ratios, HR = 0.917, 95% CI:0.889-0.981) and general health of domains in SF-12 (HR = 0.846, 95% CI:0.746-0.958) or SF-6D scores (HR = 0.010, 95% CI:0.000-0.573) were associated with an increased risk of death, with adjustment of patients’ characteristics. Increased vitality (HR = 1.151, 95% CI:1.027-1.289) and mental health (HR = 1.128, 95% CI:1.005-1.265) were associated with an increased likelihood of death. In models adjusted for competing-risk of death, those with worse HRQOL was not associated with increased risk of CRC recurrence.

Conclusions

Although self-reported HRQOL was not a significant prognostic factor for CRC recurrence, the HRQOL provided independent prognostic value about mortality in patients with advanced stage of CRC.

Could baseline health-related quality of life (QoL) predict overall survival in metastatic colorectal cancer? The results of the GERCOR OPTIMOX 1 study

Background

Health-related quality of life (QoL) has prognostic value in many cancers. A recent study found that the performance of prognostic systems for metastatic colorectal cancer (mCRC) were improvable. We evaluated the independent prognostic value of QoL for overall survival (OS) and its ability to improve two prognostic systems’performance (Köhne and GERCOR models) for patients with mCRC.

Methods

The EQ-5D questionnaire was self-completed before randomization in the OPTIMOX1, a phase III trial comparing two strategies of FOLFOX chemotherapy which included 620 previously untreated mCRC patients recruited from January 2000 to June 2002 from 56 institutions in five countries. The improvement in models’ performance (after addition of QoL) was studied with Harrell’s C-index and the net reclassification improvement.

Results

Of the 620 patients, 249 (40%) completed QoL datasets. The Köhne model could be improved by LDH, mobility and pain/discomfort; the C-index rose from 0.54 to 0.67. The associated NRI for 12-month death was 0.23 [0.05; 0.46]. Mobility and pain/discomfort could be added to the GERCOR model: the C-index varied from 0.63 to 0.68. The NRI for 12 months death was 0.35 [0.12; 0.44].

Conclusions

Mobility and pain dimensions of EQ5D are independent prognostic factors and could be useful for staging and treatment assignment of mCRC patients. Presented at the 2011 ASCO Annual Meeting (#3632).

Does change in health-related quality of life score predict survival? Analysis of EORTC 08975 lung cancer trial

BACKGROUND

Little is known about whether changes in health-related quality of life (HRQoL) scores from baseline during treatment also predict survival, which we aim to investigate in this study.

METHODS

We analysed data from 391 advanced non-small-cell lung cancer (NSCLC) patients enrolled in the EORTC 08975 study, which compared palliative chemotherapy regimens. HRQoL was assessed at baseline and after each chemotherapy cycle using the EORTC QLQ-C30 and QLQ-LC13. The prognostic significance of HRQoL scores at baseline and their changes over time was assessed with Cox regression, after adjusting for clinical and socio-demographic variables.

RESULTS

After controlling for covariates, every 10-point increase in baseline pain and dysphagia was associated with 11% and 12% increased risk of death with hazard ratios (HRs) of 1.11 and 1.12, respectively. Every 10-point improvement of physical function at baseline (HR=0.93) was associated with 7% lower risk of death. Every 10-point increase in pain (HR=1.08) was associated with 8% increased risk of death at cycle 1. Every 10-point increase in social function (HR=0.91) at cycle 2 was associated with 9% lower risk of death.

CONCLUSIONS

Our findings suggest that changes in HRQoL scores from baseline during treatment, as measured on subscales of the EORTC QLQ-C30 and QLQ-LC13, are significant prognostic factors for survival.

EORTC QLQ-C15-PAL quality of life score as a prognostic indicator of survival in patients with far advanced cancer

PURPOSE

Quality of life (QoL) and performance status predict survival in advanced cancer patients; these relationships have not been explored in the hospice palliative care setting. The aim of this study was to examine the survival predictability of patient-reported QoL using the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C15-PAL questionnaire in far advanced cancer inpatients at the very end of life.

METHODS

This is a retrospective cohort study. Patients reported QoL using the EORTC QLQ-C15-PAL. One hundred sixty-two inpatients in hospice palliative wards of six hospitals in South Korea were followed until death or the end of the study. Additional symptoms and performance status were assessed by the MD Anderson Symptom Inventory-Korean (MDASI-K), Palliative Performance Scale (PPS) and Eastern Cooperative Oncology Group (ECOG) performance status. Correlations between EORTC QLQ-C15-PAL, MDASI-K, PPS, and ECOG were assessed. Survival analyses were performed using Cox proportional hazard models.

RESULTS

Patients' median survival was less than 1 month. Physician-reported PPS significantly predicted survival (hazard ratio [HR] 0.493; p<0.001). From the EORTC QLQ-C15-PAL, patient-reported physical functioning predicted survival (HR=0.65; p<0.001). Other six domains of EORTC QLQ-C15-PAL were significantly related to survival after adjustment. Those domains were global health status, emotional functioning, fatigue, nausea/vomiting, appetite loss, and constipation.

CONCLUSIONS

EORTC QLQ-C15-PAL can be an independent prognostic factor in inpatients with far advanced cancer. Patient-reported physical functioning showed survival predictability as good as physician-reported performance status. It is notable that the QLQ instrument is useful even for patients in their final month of life. Cancer anorexia-cachexia syndrome-related symptoms may be independent prognostic symptoms. Prospective study is warranted.
