Symptom clusters during palliative chemotherapy and their influence on functioning and quality of life

Breaking the code: Using the Precision Health Model to guide research and clinical care

BACKGROUND

Precision health is a person-centered approach to health and well-being that is operationalized through evaluating omics-level profiles and their associations with the exposome. A precision health approach addresses the challenge that "one size does not fit all" in the management of an individual's health.

PURPOSE

The purpose of this white paper is to introduce a Precision Health Model and its application in research and clinical care.

METHODS

An expert panel reviewed and synthesized the extant literature related to precision health, the current state of omics' science, and common exposome factors that influence the health/illness continuum. A case study provides the framework for the application of the Precision Health Model.

DISCUSSION

Precision health and key domains are defined and serve as the platform for the development of the Precision Health Model.

CONCLUSION

Application of the Precision Health Model will provide inclusive, equitable, person-centered research and clinical care.

The Prevalence and Factors of Dyspnea Among Advanced Cancer Survivors: A Systematic Review and Meta-analysis

BACKGROUND

Dyspnea is a significant symptom in advanced cancer patients, yet comprehensive evidence on its prevalence and related factors is lacking.

OBJECTIVE

This review aims to summarize the prevalence of dyspnea among advanced cancer survivors and identify associated factors.

METHODS

MEDLINE, EMBASE, Cochrane Library, PsycINFO, CINAHL Plus, and Web of Science were searched from inception to May 2024. Observational studies focusing on advanced cancer patients reporting dyspnea were included. Two reviewers performed data extraction and quality assessment independently using the Newcastle-Ottawa Scale. Prevalence estimates were pooled using a random-effects model. Subgroup analyses and metaregression were performed to explore heterogeneity.

RESULTS

A total of 67 studies involving 78 409 advanced cancer survivors were included, revealing a pooled prevalence of dyspnea of 43% (95% prediction interval, 0.07, 0.84). Significant variations were observed based on cancer types, with lung cancer showing a prevalence of 55%. Factors associated with dyspnea were categorized using the Breathing, Thinking, Functioning clinical model: (1) breathing: physical (eg, fatigue), medical (eg, lung disease), and treatment-related (eg, palliative sedation) factors; (2) thinking: psychological (eg, anxiety) factors; and (3) functioning: performance (eg, Karnofsky Performance Status) and demographic characteristics (eg, age).

CONCLUSIONS

The findings highlight a high prevalence of dyspnea among advanced cancer survivors and identify several associated factors, stressing the need for early detection and comprehensive management strategies.

IMPLICATIONS FOR PRACTICE

Health providers can improve the quality of life for patients by effectively managing dyspnea, thereby reducing symptom burden, and alleviating psychological distress, leading to better overall well-being for patients and caregivers.

Structural equation modeling of hope, psychological distress, quality of life, and influencing factors in advanced cancer patients undergoing cancer pharmacotherapy in Japan

OBJECTIVE

The purpose of this study was to clarify the relationship between hope, psychological distress, and quality of life (QOL) of patients with advanced cancer undergoing cancer pharmacotherapy and their related factors.

METHODS

Participants were patients with advanced lung, colorectal, and breast cancer undergoing outpatient pharmacotherapy. The Herth Hope Index, Hospital Anxiety and Depression Scale, and Functional Assessment of Cancer Therapy-General were used as measurement tools in a cross-sectional survey. Data were analyzed using descriptive statistics, correlation analysis, t-test, one-way analysis of variance (ANOVA), and Structural Equation Modeling (SEM).

RESULTS

The number of valid responses to the questionnaire survey was 200 (91.7%). SEM included hope, psychological distress, QOL, social support, economic deprivation, physical symptoms, and performance status. The goodness of fit index for SEM was 0.989, adjusted goodness of fit index was 0.960, comparative fit index was 1.000, and root mean square error of approximation was 0.001. Hope had a negative impact on psychological distress (β = - 0.46) and a positive impact on QOL (β = .19).

CONCLUSION

Hope was shown to be a predictor of psychological distress and QOL in patients with advanced cancer receiving pharmacotherapy. Predictors of hope were social support and economic deprivation. The results suggest that early intervention for patients with characteristics that tend to lower levels of hope is effective in reducing patient anxiety and depression and improving QOL.

Temporal relationship between symptom cluster and quality of life in rectal cancer patients after laparoscopic anus-preserving surgery

Although it is generally recognized that symptom clusters and quality of life are related, major ambiguity arises from the difficulty in determining their causal relationship. The present study aimed to investigate longitudinal causal relationships between symptom clusters and quality of life. 128 patients with rectal cancer from Nanchong City, Sichuan Province who underwent laparoscopic anus-preserving surgery completed 4 follow-up visits, and the survey time point are 2 weeks after surgery (T1), 1 month after surgery (T2), 3 months after surgery (T3), and 6 months after surgery (T4). We used the Anderson Gastrointestinal Cancer Symptom Assessment Scale and the Colorectal Cancer Quality of Life Measurement Scale to evaluate the patient's symptom incidence, symptom severity, and quality of life at four time points respectively. After extracting symptom clusters by symptom, we constructed A four-wave cross-lagged model analyzed the causal relationship between symptom clusters and quality of life. Our research results show that the patients with rectal cancer treated by laparoscopic anus-preserving surgery have four symptom clusters during the 6 months after surgery, which are named sickness symptom cluster, gastrointestinal symptom cluster, psychological-sleep symptom cluster and Psycho-therapy related symptom clusters. Pearson correlation analysis showed that symptom clusters and quality of life were negatively correlated. The cross-lagged path effect coefficient shows that the impact of quality of life on symptom clusters is stronger than the impact of symptom clusters on quality of life (β = - 0.164 to - 0.713, P<0.05). The four-wave cross-lagged model showed that quality of life can significantly negatively predict the sickness symptom cluster and gastrointestinal symptom cluster, but this relationship is not bidirectional. Only T3 quality of life significantly negatively predicted the psycho-sleep symptom cluster, and the reverse path was also not observed. These findings provide evidence that decreases in quality of life levels precede increases in symptom cluster severity. There is a one-way temporal correlation between symptom clusters and quality of life. The decrease in quality of life leads to an increase in the severity of symptom clusters. The improvement in overall quality of life is expected to alleviate the distress of symptom clusters.

Application of Artificial Intelligence in Oncology Nursing: A Scoping Review

BACKGROUND

Artificial intelligence (AI) has been increasingly used in healthcare during the last decade, and recent applications in oncology nursing have shown great potential in improving care for patients with cancer. It is timely to comprehensively synthesize knowledge about the progress of AI technologies in oncology nursing.

OBJECTIVE

The aims of this study were to synthesize and evaluate the existing evidence of AI technologies applied in oncology nursing.

METHODS

A scoping review was conducted based on the methodological framework proposed by Arksey and O'Malley and later improved by the Joanna Briggs Institute. Six English databases and 3 Chinese databases were searched dating from January 2010 to November 2022.

RESULTS

A total of 28 articles were included in this review-26 in English and 2 in Chinese. Half of the studies used a descriptive design (level VI). The most widely used AI technologies were hybrid AI methods (28.6%) and machine learning (25.0%), which were primarily used for risk identification/prediction (28.6%). Almost half of the studies (46.4%) explored developmental stages of AI technologies. Ethical concerns were rarely addressed.

CONCLUSIONS

The applicability and prospect of AI in oncology nursing are promising, although there is a lack of evidence on the efficacy of these technologies in practice. More randomized controlled trials in real-life oncology nursing settings are still needed.

IMPLICATIONS FOR PRACTICE

This scoping review presents comprehensive findings for consideration of translation into practice and may provide guidance for future AI education, research, and clinical implementation in oncology nursing.

Self-report of symptom cluster experiences in cancer patient-caregiver dyads

PURPOSE

Symptom clusters have important health implications in the context of cancer, but the symptom cluster experiences of cancer caregivers and patient-caregiver dyads are not well studied. To date, most studies report statistically derived symptom clusters among patients and fail to consider the caregivers' experience. This study aimed to assess and characterize self-reported symptom cluster experiences in cancer patient-caregiver dyads.

METHODS

We recruited 30 patient-caregiver dyads from the outpatient oncology clinics at a Comprehensive Cancer Center in the Midwestern U.S. Participants completed web-based surveys reporting their symptom clusters at weekly intervals over 8 weeks of cancer treatment.

RESULTS

Among 48 eligible dyads, 30 (63%) agreed to participate, 29 provided data, and ≥ 80% (24 patients, 26 caregivers) completed the study. Twenty-eight patients (97%) and twenty-two caregivers (76%) reported experiencing symptoms in clusters. There was substantial variability in the symptoms reported, perceived causality, and directional relationships among symptoms, however both patients' and caregivers' frequently described symptom clusters with psychoneurologic components (co-occurring pain, fatigue, sleep disturbance, anxiety, depression, lack of appetite and/or cognitive disturbance). Symptom clusters were perceived to have a moderate impact on patients' daily lives and a mild-to-moderate impact on caregivers' daily lives.

CONCLUSION

Dyad members experienced and successfully self-reported symptom clusters, with psychoneurologic symptom clusters prevalent among both patients and their caregivers. Self-report of symptom cluster experiences provides unique insight relevant to clinical management. Findings provide foundational support for development and testing of dyad-based interventions to mitigate symptom clusters and their negative impact on daily life among cancer-patient caregiver dyads.

Factors influencing parental fatigue in children with retinoblastoma based on the unpleasant symptoms theory

Parents of children with retinoblastoma, the most common primary ocular malignant tumour in childhood, bear a heavy caregiving burden and are very susceptible to fatigue. However, little is known about their current status of fatigue and factors influencing fatigue; therefore,this study, based on the theory of unpleasant symptoms, and included 317 parents of children with retinoblastoma in China, whose general demographic data were collected, and on whom the fatigue severity scale (FSS), the generalized anxiety disorder (GAD-7) and 2-item patient health questionnaire (PHQ-2) were administered, from 9 March to 1 June 2020. The parents' FSS score and fatigue incidence were 4.41 ± 1.14 and 67.19%, respectively. The fatigue level was positively correlated with anxiety, depression, education, times of hospitalisations, and treatment types (r = 0.125-0.468, P < 0.05) and negatively correlated with health status, sleep quality, economic status, and family economic situation (r =  - 0.120 to - 0.322, P < 0.05). Parent's anxiety level, being an only child and female sex of child influenced parents' fatigue. Healthcare personnel need to focus their attention on this high-risk fatigue group and implement appropriate interventions to reduce their fatigue level, promote their physical and mental health, and facilitate better care for children.

Do All Patients Benefit From the Soothing Properties of a Conversational Nursing Intervention to Reduce Symptom Burden During Outpatient Chemotherapy?: A Multimethod Secondary Analysis

BACKGROUND

Soothing conversation (SC) is particularly promising for symptom management during outpatient chemotherapy. However, we know little about the profile of patients who are most likely to benefit from this intervention.

OBJECTIVE

To gain a better understanding of the profile of patients most likely to benefit from SC to reduce symptom burden during outpatient chemotherapy.

METHODS

We performed a multimethod secondary analysis of 2 data sets: the first gathered during a quantitative pilot trial investigating the impact of SC on patients' symptom fluctuations during chemotherapy perfusion (n = 24); the second derived from qualitative interviews about nurses' experiences with SC in this context (n = 6).

RESULTS

Secondary quantitative analysis suggests that symptom control with SC is more effective in older patients, reporting lower education, widowed status, work incapacity, advanced cancer, and undergoing chemotherapy perfusion for less than 1 hour. According to nurses' interviews, SC could best benefit patients (1) prone to anxiety and fear, (2) with unalleviated pain, (3) who are unaccompanied during treatment, and contrary to what was shown with quantitative data, (4) undergoing longer perfusion duration.

CONCLUSION

Although this study provides valuable insights, much work remains to be done to fully understand the factors that predispose patients to respond positively to SC during outpatient chemotherapy.

IMPLICATIONS FOR PRACTICE

This study extends previous research on the effectiveness of SC for symptom management during outpatient chemotherapy by comparing nurses' experience with the intervention to patients' results. Results could be used to inform the assignment and delivery of supportive communication-based interventions during chemotherapy protocols.

Symptom clusters and their impact on quality of life among Chinese patients with lung cancer: A cross-sectional study

PURPOSE

To investigate the symptom clusters of Chinese patients with lung cancer, and explore their impact on quality of life (QoL) and each of its functioning.

METHOD

A cross-sectional study was conducted between October 2022 and April 2023 among 219 lung cancer patients at a general hospital in Sichuan Province. Data were collected using a general information questionnaire, the MD Anderson Symptom Inventory, and the EORTC QLQ-C30. R within the RStudio platform was used to conduct descriptive statistics, exploratory factor analysis and multiple regression analysis.

RESULTS

Psychoneurological, respiratory, gastrointestinal and fatigue-related symptom clusters were identified, each of which was significantly negatively correlated with overall QoL, global health status/QoL and each functioning. The respiratory (β = -0.60, P = 0.02) and fatigue-related symptom cluster (β = -0.86, P = 0.02) were predictors of global health status/QoL; the fatigue-related symptom cluster predicted physical (β = -1.68, P < 0.01), role (β = -1.63, P < 0.01) and cognitive functioning (β = -1.45, P < 0.01); the psychoneurological symptom cluster was a predictor of patients' emotional functioning (β = -1.26, P < 0.01); and the psychoneurological (β = -0.81, P < 0.01) and gastrointestinal symptom cluster (β = -0.60, P = 0.05) predicted social functioning.

CONCLUSIONS

Respiratory and fatigue-related symptom clusters were strong predictors of global health status/QoL; fatigue-related, psychoneurological and gastrointestinal symptom clusters had a negative impact on patients' functioning. Nurse practitioners should pay more attention to monitoring respiratory and fatigue-related symptom clusters to identify high-risk populations in time, and tailored interventions based on symptom clusters are needed to synergistically reduce the symptom burden, thereby improving patients' QoL.

Impact of systemic cancer treatment on quality of life and mental well-being: a comparative analysis of patients with localized and advanced cancer

INTRODUCTION

This study investigated the impact of systemic cancer therapy on the quality of life, mental well-being, and life satisfaction of cancer patients.

METHODS

This prospective study was promoted by the Spanish Society of Medical Oncology (SEOM) and enrolled patients with localized, resected, or unresectable advanced cancer from 15 Spanish medical oncology departments. Patients completed surveys on quality of life (EORTC-QoL-QLQ-C30), psychological distress (BSI-18) and life satisfaction (SWLS) before and after systemic cancer treatment.

RESULTS

The study involved 1807 patients, 944 (52%) having resected, localized cancer, and 863 with unresectable advanced cancer. The mean age was 60 years, and 53% were female. The most common types of localized cancer were colorectal (43%) and breast (38%), while bronchopulmonary (32%), non-colorectal digestive (23%), and colorectal (15%) were the most frequent among those with advanced cancer. Before systemic treatment, patients with advanced cancer had poorer scores than those with localized cancer on physical, role, emotional, cognitive, social limitations, symptoms, psychological distress, and life satisfaction (all p < 0.001), but there were no differences in financial hardship. Patients with localized cancer had greater life satisfaction and better mental well-being than those with advanced cancer before systemic treatment (p < 0.001). After treatment, patients with localized cancer experienced worsening of all scales, symptoms, and mental well-being (p < 0.001), while patients with advanced disease had a minor decline in quality of life. The impact on quality of life was greater on all dimensions except economic hardship and was independent of age, cancer location, and performance status in participants with resected disease after adjuvant chemotherapy.

CONCLUSION

In conclusion, our study highlights that systemic cancer treatment can improve quality of life in patients with advanced cancer, while adjuvant treatments for localized disease may have a negative impact on quality of life and psychological well-being. Therefore, treatment decisions should be carefully evaluated on an individual basis.

Effects of chronotype-tailored bright light intervention on post-treatment symptoms and quality of life in breast cancer survivors

PURPOSE

Bright light therapy holds promise for reducing common symptoms, e.g., fatigue, experienced by individuals with cancer. This study aimed to examine the effects of a chronotype-tailored bright light intervention on sleep disturbance, fatigue, depressive mood, cognitive dysfunction, and quality of life among post-treatment breast cancer survivors.

METHODS

In this two-group randomized controlled trial (NCT03304587), participants were randomized to receive 30-min daily bright blue-green light (12,000 lx) or dim red light (5 lx) either between 19:00 and 20:00 h or within 30 min of waking in the morning. Self-reported outcomes and in-lab overnight polysomnography sleep study were assessed before (pre-test) and after the 14-day light intervention (post-test).

RESULTS

The sample included 30 women 1-3 years post-completion of chemotherapy and/or radiation for stage I to III breast cancer (mean age = 52.5 ± 8.4 years). There were no significant between-group differences in any of the symptoms or quality of life (all p > 0.05). However, within each group, self-reported sleep disturbance, fatigue, depressive mood, cognitive dysfunction, and quality of life-related functioning showed significant improvements over time (all p < 0.05); the extent of improvement for fatigue and depressive mood was clinically relevant. Polysomnography sleep findings showed that a number of awakenings significantly decreased (p = 0.011) among participants who received bright light, while stage 2 sleep significantly increased (p = 0.015) among participants who received dim-red light.

CONCLUSION

The findings support using light therapy to manage post-treatment symptoms in breast cancer survivors. The unexpected symptom improvements among dim-red light controls remain unexplained and require further investigation.

Cancer-Related Symptom Frameworks Using a Biopsychosocial-Spiritual Perspective: A Scoping Review

BACKGROUND

Research to understand and manage cancer-related symptoms continues to advance, yet work that more fully adopts a biopsychosocial-spiritual view of symptoms is needed.

OBJECTIVE

The purpose of this article is to review existing frameworks that have the potential to guide research on cancer-related symptoms, to explore the characteristics of each framework, and to appraise each using a biopsychosocial-spiritual lens.

METHODS

A scoping review was conducted to identify available frameworks that could be applied to guide cancer-related symptom research and to assess their characteristics. Research questions and criteria were formulated at the outset, followed by identifying relevant publications detailing novel frameworks, charting data, and collating results. Upon identification of available frameworks, each was appraised for alignment with a standard definition of "biopsychosocial-spiritual."

RESULTS

Eleven frameworks were identified to guide cancer-related symptom research. All were developed in the United States, led by nurse scientists, including symptom experiences as well as their antecedents and outcomes, and could be applied to one or more concurrent cancer-related symptoms. While all 11 frameworks included biopsychosocial dimensions, only 4 included spirituality.

CONCLUSIONS

Four biopsychosocial-spiritual frameworks offer unique insight to support advancement of cancer-related symptom research and practice from a holistic perspective. This foundational work could lead to development and validation of new frameworks and modification of existing frameworks to more closely align with a biopsychosocial-spiritual view of cancer-related symptoms. This review offers a starting point to carefully and explicitly adopt frameworks in research and practice with increased emphasis on considering spiritual dimensions of symptoms.

Fatigue-related symptom clusters and functional status of older adults in hospice

BACKGROUND

Fatigue is frequently co-existing with other symptoms and is highly prevalent among patients with cancer and geriatric population. There was a lack of knowledge that focus on fatigue clusters in older adults with cancer in hospice care.

OBJECTIVES

To identify fatigue-related symptom clusters in older adult hospice patients and discover to what extent fatigue-related symptom clusters predict functional status while controlling for depression.

METHOD

This was a cross-sectional study in a sample of 519 older adult hospice patients with cancer, who completed the Memorial Symptom Assessment Scale, the Center for Epidemiological Studies Depression, Boston Short Form Scale, and the Palliative Performance Scale. Data from a multi-center symptom trial were extracted for this secondary analysis using exploratory factor analysis and hierarchical multiple regression analysis.

RESULTS

Data from 519 patients (78 ± 7 years) with terminal cancer who received hospice care under home healthcare services revealed that 39% of the participants experienced fatigue-related symptom clusters (lack of energy, feeling drowsy, and lack of appetite). The fatigue cluster was significantly associated positively with depression (r = 0.253, p < 0.01), and negatively with functional status (r = -0.117, p < 0.01) and was a strong predictor of participants' low functional status. Furthermore, depression made a significant contribution to this predictive relationship.

CONCLUSION

Older adult hospice patients with cancer experienced various concurrent symptoms. The fatigue-specific symptom cluster was identified significantly associated with depression and predicted functional status. Fatigue should be routinely monitored in older adults, especially among hospice cancer patients, to help reduce psychological distress and prevent functional decline.

Early integration of palliative care into oncological care: a focus on patient-important outcomes

BACKGROUND

Globally, cancer remains one of the leading causes of mortality. Palliative care is designed to meet a range of cancer patients' priority issues, including the management of pain and other cancer-associated symptoms. Routine palliative care envisages the provision of not just medical therapy, but also psychological support, social support and spiritual assistance. What constitutes the best model for palliative care remains a matter of debate.

AIM

This review was undertaken with the aim to discuss different aspects of early integration of palliative care into oncological care, with a focus on patient-important outcomes.

METHODS

A comprehensive search of publications was conducted with a focus on integrative palliative care for incurable cancer patients. For this purpose, the following databases and search engines were used: Scopus, PubMed, Cochrane Library, Research Gate, Google Scholar, eLIBRARY and Cyberleninka.

RESULTS

A comprehensive approach with early integration of different medical services appears to be the most promising. Integrative palliative care is best provided via specialised interdisciplinary teams, given that all members maintain systemic communications and regularly exchange information. This model ensures that timely and adequate interventions are provided to address the needs of patients.

CONCLUSION

Further research is needed to pinpoint the most optimal strategies to deliver palliative care and make it as tailored to the patient's demands as possible.

Understanding the experiences of older caregivers of patients with lung cancer during palliative chemotherapy in China: a qualitative study

PURPOSE

Although there has been an increase in research on caregivers of patients with cancer, there has been little focus on the specific experiences of older caregivers of patients with lung cancer and the effect of their cultural backgrounds on their experiences. This study explored the caregiver experience among the ageing population in China.

METHODS

Older caregivers of patients with lung cancer undergoing palliative chemotherapy were recruited. Data were collected using a qualitative descriptive design involving semi-structured interviews, which were recorded, transcribed verbatim and analysed qualitatively using inductive content analysis.

RESULTS

Eighteen caregivers aged 61-81 years completed the interviews. The following four themes were identified: physical difficulty, living with ambivalence, perception of role and role-related behaviour changes. These themes enabled a greater understanding of role-related behaviours in older caregivers and their challenges in addressing biological and psychosocial challenges related to older age.

CONCLUSION

The present study highlighted the vulnerability and perceived challenges of the role of older caregivers. These findings help lay the foundation for interventions to improve the care provided to caregivers and their health outcomes, especially caregivers with chronic conditions.

Effect of exercise on functional capacity in patients with advanced cancer: A meta-analysis of randomized controlled trials

PURPOSE

To determine the impact of exercise on functional capacity, measured through the "Six minutes walking test" (6MWT) in patients with advanced cancer stage.

METHODS

Systematic research on PubMed, Cochrane Library, and SportDiscus was conducted. Randomized controlled trials were eligible if they examined the effect of exercise on 6MWT.

RESULTS

Overall, a total of ten trials were included in the primary analysis. Compared to the controls, the exercise intervention was associated with an increase in functional capacity (+20.86 m; CI: -5.90 to 47.72, p = 0.12) although not reaching the statistical significance. Sensitivity analysis revealed an improvement for studies proposing a supervised exercise intervention towards the statistical significance. Few adverse events were associated with exercise training, and the median withdrawals rate was 17%.

CONCLUSIONS

Exercise may have a beneficial role on functional capacity in patients with advanced cancer, especially if supervised.

Assessment of symptoms among among patients living with cancer: prevalence, distress and its correlation with quality of life

Background: Several symptoms known to be experienced by cancer patients receiving palliative care remain under-reported, inadequately managed and unexplored in Jordan. Aim: To describe the prevalence of symptoms, the distress caused and the correlation with quality-of-life among cancer patients receiving palliative care in Jordan. Methods: A cross-sectional correlational survey design was used. The Rotterdam Symptom Checklist and the Quality-of-Life Index-Cancer version were used for data collection. Data were analysed using descriptive statistics, unpaired t-test and Pearson correlation coefficients. Results: The sample comprises of 124 patients with a mean age of 55.7 years (SD=12.9). A total of 57.3% of them were females. Patients reported having an average of 17.3 (SD=7.1) symptoms. The most reported symptoms were tiredness (90.3%), lack of energy (81.5%), sore muscles (81.5%) and worry (76.6%). The mean total score for quality of life was 17.9 (SD=5.9) out of 30. A negative (P<0.05) relationship was found between the number of concurrent symptoms and the total quality of life score. Conclusions: Palliative care patients in Jordan reported a high number of co-occurring symptoms and experienced high levels of symptom distress, which negatively impacted their quality of life. Further research to evaluate the impact of total symptom management, its efficacy and feasibility is needed.

Symptom Clusters and Quality of Life in Gastric Cancer Patients Receiving Chemotherapy

CONTEXT

Although gastric cancer is one of the most common tumors worldwide, there is little knowledge about symptom clusters and quality of life (QoL) in this population.

OBJECTIVES

The objectives were to identify the symptom clusters in gastric cancer patients receiving chemotherapy, and explore their effects on QoL.

METHODS

Gastric cancer patients receiving chemotherapy were recruited. Data were collected using the Memorial Symptom Assessment Scale Short Form, the Functional Assessment of Cancer Therapy-Gastric and the self-designed General Information Evaluation Form. The symptom clusters were extracted through the exploratory factor analysis. The influencing factors of symptom clusters and their effects on QoL were identified using multiple linear regression analysis.

RESULTS

A total of 322 participants were enrolled from three medical centers. Five factors were identified in this exploratory factor analysis based on symptom prevalence, namely fatigue related symptom cluster, epithelial symptom cluster, neurologic symptom cluster, malnutrition related symptom cluster and psychological symptom cluster (χ² = 31.470, P < 0.05). The affecting factors across symptom clusters and QoL subscales were relatively stable, but also different. Generally, fatigue related symptom cluster, malnutrition related symptom cluster and psychological symptom cluster demonstrated significantly negative effects on all aspects of QoL except social well being.

CONCLUSION

Five symptom clusters were identified in gastric cancer patients receiving chemotherapy in mainland China. The symptom clusters negatively contributed to the variance in all aspects of QoL except social well being. Further studies should examine interventions for symptom clusters, their influencing factors, and their effects on improving QoL.

Sleeping-related distress in a palliative care population: A national, prospective, consecutive cohort

BACKGROUND

Sleep, a multi-dimensional experience, is essential for optimal physical and mental wellbeing. Poor sleep is associated with worse wellbeing but data are scarce from multi-site studies on sleeping-related distress in palliative care populations.

AIM

To evaluate patient-reported distress related to sleep and explore key demographic and symptom distress related to pain, breathing or fatigue.

DESIGN

Australian national, consecutive cohort study with prospectively collected point-of-care data using symptoms from the Symptom Assessment Scale (SAS).

SETTING/PARTICIPANTS

People (n = 118,117; 475,298 phases of care) who died while being seen by specialist palliative care services (n = 152) 2013-2019. Settings: inpatient (direct care, consultative); community (outpatient clinics, home, residential aged care).

RESULTS

Moderate/severe levels of sleeping-related distress were reported in 11.9% of assessments, more frequently by males (12.7% vs 10.9% females); people aged <50 years (16.2% vs 11.5%); and people with cancer (12.3% vs 10.0% for other diagnoses). Sleeping-related distress peaked with mid-range Australia-modified Karnofsky Performance Status scores (40-60).Strong associations existed between pain-, breathing- and fatigue-related distress in people who identified moderate/severe sleeping-related distress, adjusted for age, sex and functional status. Those reporting moderate/severe sleeping-related distress were also more likely to experience severe pain-related distress (adjusted odds ratios [OR] 6.6; 95% confidence interval (CI) 6.3, 6.9); breathing-related distress (OR 6.2; 95% CI 5.8, 6.6); and fatigue-related distress (OR 10.4; 95% CI 9.99-10.8).

CONCLUSIONS

This large, representative study of palliative care patients shows high prevalence of sleeping-related distress, with strong associations shown to distress from other symptoms including pain, breathlessness and fatigue.

A Systematic Review of the Safety, Feasibility and Benefits of Exercise for Patients with Advanced Cancer

Simple Summary

Most advanced cancer patients suffer from severe symptoms due to cancer and medical treatment. Common symptoms are physical weakness, mental problems, and tiredness. Research has shown that exercise positively influences cancer-related side effects during and after treatment and longevity in cancer survivorship. However, exercise as a supportive therapy in advanced cancer patients is still not recommended in oncological guidelines. Therefore, the aim of this systematic review was to assess the safety, feasibility, and benefits of exercise for patients with advanced cancer. Based on the results of 14 included exercise intervention studies, we conclude that exercise is safe and feasible, seems to improve physical performance, and may lower symptoms like chronic tiredness. Early integration of exercise for advanced cancer patients should be considered as usual care as a supportive strategy.

Abstract

Exercise therapy is a common supportive strategy in curative cancer treatment with strong evidence regarding its positive effects on, for example, cancer-related fatigue, health- related quality of life, and physical function. In the field of advanced cancer patients, knowledge about exercise as a useful supportive strategy is missing. The aim of this systematic review was to evaluate the feasibility and safety of exercise interventions as well as its effects on lowering the symptom burden. We included randomized controlled trials and nonrandomized controlled trials with advanced cancer patients receiving any type of exercise intervention. After an extensive literature search (in accordance to PRIMSA guidelines) in PubMed, Cochrane Library, and SPORTDiscus, 14 studies including 940 participants with different cancer entities were eligible. The results indicated the safety of exercise. In total, 493 participants received exercise interventions, with nine adverse events and no severe adverse events. The median recruitment rate was 68.33%, and adherence to exercise intervention was 86%. Further research with a high-quality and larger sample size is needed to clarify the potential of exercise with advanced cancer patients. Different advanced cancer entities have distinguished symptoms, and future research should construct entities-specific trial populations to figure out the best supportive exercise interventions.

Health-related quality of life with palbociclib plus endocrine therapy versus capecitabine in postmenopausal patients with hormone receptor-positive metastatic breast cancer: Patient-reported outcomes in the PEARL study

BACKGROUND

The PEARL study showed that palbociclib plus endocrine therapy (palbociclib/ET) was not superior to capecitabine in improving progression-free survival in postmenopausal patients with metastatic breast cancer resistant to aromatase inhibitors, but was better tolerated. This analysis compared patient-reported outcomes.

PATIENTS AND METHODS

The PEARL quality of life (QoL) population comprised 537 patients, 268 randomised to palbociclib/ET (exemestane or fulvestrant) and 269 to capecitabine. Patients completed the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR23 and EQ-5D-3L questionnaires. Changes from the baseline and time to deterioration (TTD) were analysed using linear mixed-effect and stratified Cox regression models, respectively.

RESULTS

Questionnaire completion rate was high and similar between treatment arms. Significant differences were observed in the mean change in global health status (GHS)/QoL scores from the baseline to cycle 3 (2.9 for palbociclib/ET vs. -2.1 for capecitabine (95% confidence interval [CI], 1.4-8.6; P = 0.007). The median TTD in GHS/QoL was 8.3 months for palbociclib/ET versus 5.3 months for capecitabine (adjusted hazard ratio, 0.70; 95% CI, 0.55-0.89; P = 0.003). Similar improvements for palbociclib/ET were also seen for other scales as physical, role, cognitive, social functioning, fatigue, nausea/vomiting and appetite loss. No differences were observed between the treatment arms in change from the baseline in any item of the EQ-5D-L3 questionnaire as per the overall index score and visual analogue scale.

CONCLUSION

Patients receiving palbociclib/ET experienced a significant delay in deterioration of GHS/QoL and several functional and symptom scales compared with capecitabine, providing additional evidence that palbociclib/ET is better tolerated.

Feasibility and acceptability of hypnosis-derived communication administered by trained nurses to improve patient well-being during outpatient chemotherapy: a pilot-controlled trial

Purpose

This pilot-controlled trial aimed to examine the feasibility and acceptability of hypnosis-derived communication (HC) administered by trained nurses during outpatient chemotherapy to optimize symptom management and emotional support — two important aspects of patient well-being in oncology.

Methods

The trial was conducted in two outpatient oncology units: (1) intervention site (usual care with HC), and (2) control site (usual care). Nurses at the intervention site were invited to take part in an 8-h training in HC. Participants’ self-ratings of symptoms and emotional support were gathered at predetermined time points during three consecutive outpatient visits using the Edmonton Symptom Assessment Scale and the Emotional Support Scale.

Results

Forty-nine patients (24 in the intervention group, 25 in the control group) with different cancer types/stages were recruited over a period of 3 weeks and completed the study. All nurses (N = 10) at the intervention site volunteered to complete the training and were able to include HC into their chemotherapy protocols (about ± 5 min/intervention). Compared to usual care, patients exposed to HC showed a significant reduction in physical symptoms during chemotherapy. In contrast, perception of emotional support did not show any significant effect of the intervention. Participants exposed to HC report that the intervention helped them relax and connect on a more personal level with the nurse during chemotherapy infusion.

Conclusions

Our results suggest that HC is feasible, acceptable, and beneficial for symptom management during outpatient chemotherapy. While future studies are needed, hypnosis techniques could facilitate meaningful contacts between cancer patients and clinicians in oncology.

Diverse patient trajectories during cytotoxic chemotherapy: Capturing longitudinal patient-reported outcomes

Background

High‐value cancer care balances effective treatment with preservation of quality of life. Chemotherapy is known to affect patients’ physical and psychological well‐being negatively. Patient‐reported outcomes (PROs) provide a means to monitor declines in a patients’ well‐being during treatment.

Methods

We identified 741 oncology patients undergoing chemotherapy in our electronic health record (EHR) system who completed Patient‐Reported Outcomes Measurement Information System (PROMIS) surveys during treatment at a comprehensive cancer center, 2013–2018. PROMIS surveys were collected before, during, and after chemotherapy treatment. Linear mixed‐effects models were performed to identify predictors of physical and mental health scores over time. A k‐mean cluster analysis was used to group patient PROMIS score trajectories.

Results

Mean global physical health (GPH) scores were 48.7 (SD 9.3), 47.7 (8.8), and 48.6 (8.9) and global mental health (GMH) scores were 50.4 (8.6), 49.5 (8.8), and 50.6 (9.1) before, during, and after chemotherapy, respectively. Asian race, Hispanic ethnicity, public insurance, anxiety/depression, stage III cancer, and palliative care were predictors of GPH and GMH decline. The treatment time period was also a predictor of both GPH and GMH decline relative to pre‐treatment. Trajectory clustering identified four distinct PRO clusters associated with chemotherapy treatment.

Conclusions

Patient‐reported outcomes are increasingly used to help monitor cancer treatment and are now a part of care reimbursement. This study leveraged routinely collected PROMIS surveys linked to EHRs to identify novel patient trajectories of physical and mental well‐being in oncology patients undergoing chemotherapy and potential predictors. Supportive care interventions in high‐risk populations identified by our study may optimize resource deployment.

Novelty and impact

This study leveraged routinely collected patient‐reported outcome (PROMIS) surveys linked to electronic health records to characterize oncology patients’ quality of life during chemotherapy. Important clinical and demographic predictors of declines in quality of life were identified and four novel trajectories to guide personalized interventions and support. This work highlights the utility of monitoring patient‐reported outcomes not only before and after, but during chemotherapy to help advert adverse patient outcomes and improve treatment adherence.

The role of spirituality in symptom experiences among adults with cancer

PURPOSE

Adults with cancer experience symptoms such as pain, fatigue, depression, and sleep disturbance, which can impede quality of life. Research suggests that addressing spirituality may be one route to support holistic symptom management. The purpose of this study is to explore how spirituality relates to common cancer-related symptoms (including severity, distress, and interference) among a sample of adults with cancer.

METHODS

This is a secondary analysis of data from N = 200 solid tumor cancer patients undergoing chemotherapy. Symptom experiences were assessed with a modified version of the Memorial Symptom Assessment Scale and the M. D. Anderson Symptom Inventory-Interference Subscale. Spirituality was assessed using a subset of items from the Fox Simple Quality of Life Scale. A series of ordinal and linear regressions were used to examine the relationship between spirituality and symptom severity, symptom-related distress, and symptom interference across four cancer-related symptoms (pain, fatigue, depression, and sleep disturbance).

RESULTS

Higher spirituality trended toward an association with lower pain severity, although results were not significant (p < .058). Higher spirituality was significantly associated with lower severity of fatigue (p < .003), depression (p < .006), and sleep disturbance (p < .004). Spirituality was not significantly associated with any of the four symptom-related distress outcomes. Higher spirituality was significantly associated with lower overall symptom interference (p < .004).

DISCUSSION

This study highlights the role of spirituality in the experience of cancer-related symptoms. Additional research is needed among more diverse samples of people with cancer. This foundational work could lead to the development of symptom management interventions that incorporate aspects of spirituality.

Stable Symptom Clusters and Evolving Symptom Networks in Relation to Chemotherapy Cycles

CONTEXT

The existence of stable symptom clusters with variations or changes in cluster membership and the merging of symptom clusters over time urge us to investigate how symptom relationships change over time.

OBJECTIVES

To identify stable symptom clusters and understand networks among symptoms using longitudinal data.

METHODS

Secondary data analysis was conducted using data from a nonblinded randomized clinical trial, which evaluated the effect and feasibility of the developed cancer symptom management system. For the present study, data from all participants of the original trial were analyzed (N = 249). The severity of 20 symptoms was measured before the start of chemotherapy (CTx) and during the initial four cycles of CTx. Symptom clusters were identified using principal component and hierarchical cluster analyses, and network analysis was used to explore the relationships among symptoms.

RESULTS

Three common symptom clusters were identified. The first cluster consisted of anxiety, depression, sleep disturbance, pain, and dyspnea. Fatigue, difficulty concentrating, and drowsiness formed a second stable cluster throughout the CTx cycles. The third cluster comprised loss of appetite, taste change, nausea, and vomiting. In terms of the symptom networks, close relationships were recognized, irrespective of symptom severity level, between anxiety and depression, fatigue and drowsiness, and loss of appetite and taste change. Fatigue was the most central symptom with the highest strength. Edge thickening after starting CTx demonstrated evolving symptom networks in relation to CTx cycles.

CONCLUSION

Stable symptom clusters and evolving networks were identified. The most central symptom was fatigue; however, the paucity of studies that investigated symptom networks and central symptoms calls for further investigations on these phenomena. Identification of central symptoms and underlying mechanisms will guide efficient symptom management. Future studies will need to focus on developing comprehensive interventions for managing symptom clusters or targeting central symptoms.

Symptom Clusters and Quality of Life in Cervical Cancer Patients Receiving Concurrent Chemoradiotherapy: The Mediating Role of Illness Perceptions

OBJECTIVES

Although studies shows that symptom clusters and illness perceptions are negatively associated with quality of life (QoL), it is unclear how these variables of cervical cancer patients who receive concurrent chemoradiotherapy (CCRT) relate to each other. This study aimed to identify the symptom clusters in cervical cancer patients who receive CCRT and evaluate the mediating effect of illness perceptions on the relationship between symptom clusters and QoL.

METHODS

A cross-sectional survey was conducted on 286 cervical cancer patients receiving CCRT from October 2019 to October 2020. M.D. Anderson Symptom Inventory, Brief Illness Perception Questionnaire, and Functional Assessment Cancer Therapy-Cervix were applied to investigate the symptom clusters, illness perceptions and QoL of the participants, respectively. Exploratory factor analysis was conducted to identify symptom clusters. The relationships among symptom clusters, illness perceptions, and QoL were analyzed with the structural equation modeling.

RESULTS

A total of four symptom clusters were identified, including psychological status symptom cluster, therapy side-effect symptom cluster, sickness symptom cluster, and gastrointestinal symptom cluster (χ² = 1,552.282, Df = 78, P < 0.001). Symptom clusters, illness perceptions, and QoL were significantly correlated. Symptom clusters had significant direct (β = -0.38, P < 0.001) and indirect effects (β = -0.21, P < 0.001) on QoL.

CONCLUSION

Illness perceptions played a significant mediating role between symptom clusters and QoL in cervical cancer patients receiving CCRT. Strategies like prompting effective symptom management for the purposes of alleviating illness perceptions may contribute to improving their QoL.

Drinking Ice-Cold Water Reduces the Severity of Anticancer Drug-Induced Taste Dysfunction in Mice

Taste disorders are common adverse effects of cancer chemotherapy that can reduce quality of life and impair nutritional status. However, the molecular mechanisms underlying chemotherapy-induced taste disorders remain largely unknown. Furthermore, there are no effective preventive measures for chemotherapy-induced taste disorders. We investigated the effects of a combination of three anticancer drugs (TPF: docetaxel, cisplatin and 5-fluorouracil) on the structure and function of mouse taste tissues and examined whether the drinking of ice-cold water after TPF administration would attenuate these effects. TPF administration significantly increased the number of cells expressing apoptotic and proliferative markers. Furthermore, TPF administration significantly reduced the number of cells expressing taste cell markers and the magnitudes of the responses of taste nerves to tastants. The above results suggest that anticancer drug-induced taste dysfunction may be due to a reduction in the number of taste cells expressing taste-related molecules. The suppressive effects of TPF on taste cell marker expression and taste perception were reduced by the drinking of ice-cold water. We speculate that oral cryotherapy with an ice cube might be useful for prophylaxis against anticancer drug-induced taste disorders in humans.

Factors associated with sleep quality during chemotherapy: An integrative review

Aim

To identify the most important factors associated with sleep pattern changes in patients with cancer during chemotherapy treatment.

Design

An integrative review of the literature was performed between December 2017-August 2018.

Methods

Two independent reviewers searching the National Library of Medicine (PubMed/MEDLINE), Cumulative Index of Nursing and Allied Health Literature (CINAHL) and Latin American and Caribbean Literature in Health Sciences (LILACS), Scopus and Scielo. The process followed the recommendations of the PRISMA tool. A total of 16 articles were selected for the final study sample, including 11 cohort studies and 5 cross-sectional studies.

Results

The predisposing factors for the most prevalent sleep disturbances were precipitants related to the disease and the treatment, such as fatigue, pain, depression, anxiety and distress. Predisposing factors related to lifestyle and demographic characteristics have a significant correlation with sleep disturbances.

Symptom clusters in newly diagnosed glioma patients: which symptom clusters are independently associated with functioning and global health status?

Background

Symptom management in glioma patients remains challenging, as patients suffer from various concurrently occurring symptoms. This study aimed to identify symptom clusters and examine the association between these symptom clusters and patients’ functioning.

Methods

Data of the CODAGLIO project was used, including individual patient data from previously published international randomized controlled trials (RCTs) in glioma patients. Symptom prevalence and level of functioning were assessed with European Organisation for Research and Treatment of Cancer (EORTC) quality of life QLQ-C30 and QLQ-BN20 self-report questionnaires. Associations between symptoms were examined with Spearman correlation coefficients and partial correlation networks. Hierarchical cluster analyses were performed to identify symptom clusters. Multivariable regression analyses were performed to determine independent associations between the symptom clusters and functioning, adjusted for possible confounders.

Results

Included in the analysis were 4307 newly diagnosed glioma patients from 11 RCTs who completed the EORTC questionnaires before randomization. Many patients (44%) suffered from 5–10 symptoms simultaneously. Four symptom clusters were identified: a motor cluster, a fatigue cluster, a pain cluster, and a gastrointestinal/seizures/bladder control cluster. Having symptoms in the motor cluster was associated with decreased (≥10 points difference) physical, role, and social functioning (betas ranged from −11.3 to −15.9, all P < 0.001), independent of other factors. Similarly, having symptoms in the fatigue cluster was found to negatively influence role functioning (beta of −12.3, P < 0.001), independent of other factors.

Conclusions

Two symptom clusters, the fatigue and motor cluster, were frequently affected in glioma patients and were found to independently have a negative association with certain aspects of patients’ functioning as measured with a self-report questionnaire.

Systematic symptom and problem assessment at admission to the palliative care ward - perspectives and prognostic impacts

BACKGROUND

Symptom assessment is essential in palliative care, but holds challenges concerning implementation and relevance. This study aims to evaluate patients' main symptoms and problems at admission to a specialist inpatient palliative care (SIPC) ward using physician proxy- and patient self-assessment, and aims to identify their prognostic impact as well as the agreement between both assessments.

METHODS

Within 12 h after admission, palliative care specialists completed the Symptom and Problem Checklist of the German Hospice and Palliative Care Evaluation (HOPE-SP-CL). Patients either used the new version of the minimal documentation system for patients in palliative care (MIDOS) or the Integrated Palliative Care Outcome Scale (IPOS) plus the Distress Thermometer (DT).

RESULTS

Between 01.01.2016-30.09.2018, 1206 patients were included (HOPE-SP-CL 98%; MIDOS 21%, IPOS 34%, DT 27%) whereof 59% died on the ward. Proxy-assessment showed a mean HOPE-SP-CL Total Score of 24.6 ± 5.9 of 45. Most frequent symptoms/problems of at least moderate intensity were weakness (95%), needs of assistance with activities of daily living (88%), overburdening of family caregivers (83%), and tiredness (75%). Factor analysis identified four symptom clusters (SCs): (1) Deteriorated Physical Condition/Decompensation of Home Care, (2) Emotional Problems, (3) Gastrointestinal Symptoms and (4) Other Symptoms. Self-assessment showed a mean MIDOS Total Score of 11.3 ± 5.3 of 30, a mean IPOS Total Score of 32.0 ± 9.0 of 68, and a mean distress of 6.6 ± 2.5 of 10. Agreement of self- and proxy-assessment was moderate for pain (ƙ = 0.438) and dyspnea (ƙ = 0.503), fair for other physical (ƙ = 0.297 to 0.394) and poor for psychological symptoms (ƙ = 0.101 to 0.202). Multivariate regression analyses for single symptoms and SCs revealed that predictors for dying on the SIPC ward included impaired ECOG performance status, moderate/severe dyspnea, appetite loss, tiredness, disorientation/confusion, and the SC Deteriorated Physical Condition/Decompensation of Home Care.

CONCLUSION

Admissions to a SIPC ward are mainly caused by problems impairing mobility and autonomy. Results demonstrate that implementation of self- and reliability of proxy- and self-assessment is challenging, especially concerning non-physical symptoms/problems. We identified, specific symptoms and problems that might provide information needed for treatment discussions regarding the medical prognosis.

Zoledronic Acid Improves Muscle Function in Healthy Mice Treated with Chemotherapy

Carboplatin is a chemotherapy drug used to treat solid tumors but also causes bone loss and muscle atrophy and weakness. Bone loss contributes to muscle weakness through bone-muscle crosstalk, which is prevented with the bisphosphonate zoledronic acid (ZA). We treated mice with carboplatin in the presence or absence of ZA to assess the impact of bone resorption on muscle. Carboplatin caused loss of body weight, muscle mass, and bone mass, and also led to muscle weakness as early as 7 days after treatment. Mice treated with carboplatin and ZA lost body weight and muscle mass but did not lose bone mass. In addition, muscle function in mice treated with ZA was similar to control animals. We also used the anti-TGFβ antibody (1D11) to prevent carboplatin-induced bone loss and showed similar results to ZA-treated mice. We found that atrogin-1 mRNA expression was increased in muscle from mice treated with carboplatin, which explained muscle atrophy. In mice treated with carboplatin for 1 or 3 days, we did not observe any bone or muscle loss, or muscle weakness. In addition, reduced caloric intake in the carboplatin treated mice did not cause loss of bone or muscle mass, or muscle weakness. Our results show that blocking carboplatin-induced bone resorption is sufficient to prevent skeletal muscle weakness and suggests another benefit to bone therapy beyond bone in patients receiving chemotherapy. © 2019 American Society for Bone and Mineral Research.

Symptom Clusters and Health-related Quality of Life in Chinese patients with Chronic Obstructive Pulmonary Disease

This study aimed to identify symptom clusters of chronic obstructive pulmonary disease (COPD) and to examine the relationship between symptom clusters and health-related quality of life (HRQoL). It included 154 hospitalized patients with COPD. The majority of the participants (88.6%) were aged 60 years and above, and the numbers of men and women were approximately equal (men: 55.2%). The Charlson Comorbidity Index (CCI), the Memorial Symptom Assessment Scale (MSAS), and the Chinese version of the Clinical COPD Questionnaire (CCQ) were used to evaluate comorbidity, participant's symptoms, and HRQoL, respectively. Five symptom clusters were identified using exploratory factor analysis, and symptom clusters, especially the Psychological, Pain and Fatigue, GI, and Dyspnea-Sweat symptom clusters, had negative effects on HRQoL in patients with COPD. Understanding the patterns and occurrences of symptom clusters could be essential for developing effective interventions to manage COPD symptoms and improve the patients' HRQoL.

Utilizing the Advances in Digital Health Solutions to Manage Care in Cancer Patients

In recent years, the clinical context for cancer has changed, and it is now characterized by extended survival rates and more diverse and complex cancer trajectories and symptomatology. The changes in the landscape of cancer care also include a shift towards the home setting or the outpatient setting with an increased amount of care being delivered at home or transferred to the patients themselves and their family caregivers. These changes have also impacted the type and amount of information required by the patients and their caregivers as well as the type of care needs that are to be addressed by health-care professionals. Finally, the transitions within the health-care setting might also create a caring gap that the patient is left to deal with independently or with minimal support. These changes have led to the emergence of innovative digital/technological solutions for supporting patients during their cancer care continuum.

Estimating the Frequency, Severity, and Clustering of SPADE Symptoms in Chronic Painful Chemotherapy-Induced Peripheral Neuropathy

BACKGROUND

Patients undergoing treatment for cancer commonly experience symptoms such as sleep disturbance, pain, anxiety, depression, and low energy/fatigue (SPADE), subsequently altering physical function and complicating effective symptom management. However, little is known about the frequency, severity, and clustering of SPADE symptoms in individuals with chronic painful chemotherapy-induced peripheral neuropathy (CIPN). Aims/Design: The purpose of this cross-sectional, secondary analysis was to describe the frequency, severity, and clustering of SPADE symptoms and their association with physical function in individuals with chronic painful CIPN. Participants/Subjects: Sixty individuals with chronic painful CIPN were recruited from five academic and community oncology outpatient center to participate in a randomized controlled pilot trial designed to test the efficacy of a cognitive behavioral therapy-based pain management program.

METHODS

Participants completed the 0-10 Average CIPN Pain Numerical Rating Scale and Patient-Reported Outcome Measurement Information System measures for sleep-related impairment, anxiety, depression, fatigue, and pain interference via tablet before being randomly assigned to a study arm. The frequency, severity, and clustering of SPADE symptoms were calculated via descriptive statistics and Partitioning Around Medoids cluster analysis. Spearman rank correlation was performed to determine the association between number of SPADE symptoms and pain interference severity.

RESULTS AND CONCLUSIONS

Participants (n = 59) experienced numerous SPADE symptoms. 66.1% of participants experienced at least two SPADE symptoms concurrently. The cluster analysis revealed high (n = 36) and low (n = 23) severity subgroups. There was a moderate correlation (r = 0.48) between the number of SPADE symptoms and pain interference severity. Determining the clustering of SPADE symptoms in individuals with chronic painful CIPN may lead to targeted multifaceted interventions to improve physical function.

Neuropathic symptoms, physical and emotional well-being, and quality of life at the end of life

The purpose of this cross-sectional, descriptive study was to assess differences in neuropathic symptoms, physical and emotional well-being, and quality of life in cancer patients at the end of life compared to those without neuropathic symptoms. Neuropathic symptoms were defined as numbness and tingling in the hands and/or feet. A secondary analysis of data from two hospices in Central Florida was performed. Adults (n = 717) with a cancer diagnosis, an identified family caregiver, and who were receiving hospice services, were eligible. The prevalence of numbness/tingling in the hands or feet was 40% in this sample of hospice patients with cancer. Participants with neuropathic symptoms of numbness/tingling had a significantly higher prevalence of pain (76.7% vs. 67.0%; p = .006), difficulty with urination (29.4% vs. 20.3%; p = .007), shortness of breath (64.9% vs. 54.1%; p = .005), dizziness/lightheadedness (46.0% vs. 28.2%; p < .001), sweats (35.5% vs. 20.3%; p < .001), worrying (50.7% vs. 37.3%; p = .001), feeling irritable (38.5% vs. 28.7%; p = .008), feeling sad (48.2% vs. 37.8%; p = .008), and difficulty concentrating (46.2% vs. 32.5%; p < .001). They also reported significantly higher overall symptom intensity and symptom distress scores (p = < .001), higher pain severity (p = .001) and pain distress (p = .002), and decreased quality of life (p = .002) compared to those without numbness/tingling. Neuropathic symptoms are emotionally distressing at the end of life and associated with higher symptom burden and diminished quality of life.

Misery Loves Company: Presenting Symptom Clusters to Urgent Care by Patients Receiving Antineoplastic Therapy

PURPOSE

The Centers for Medicare & Medicaid Services (CMS) identifies suboptimal management of treatment toxicities as a care gap and proposes the measurement of hospital performance on the basis of emergency department visits for 10 common symptoms. Current management strategies do not address symptom co-occurrence.

METHODS

We evaluated symptom co-occurrence in three patient cohorts that presented to a cancer hospital urgent care center in 2016. We examined both the CMS-identified symptoms and an expanded clinician-identified set defined as symptoms that could be safely managed in the outpatient setting if identified early and managed proactively. The cohorts included patients who presented with a CMS-defined symptom within 30 days of treatment, patients who presented within 30 days of treatment with a symptom from the expanded set, and patients who presented with a symptom from the expanded set within 30 days of treatment start. Symptom co-occurrence was measured by Jaccard index. A community detection algorithm was used to identify symptom clusters on the basis of a random walk process, and network visualizations were used to illustrate symptom dynamics.

RESULTS

There were 6,429 presentations in the CMS symptom-defined cohort. The network analysis identified two distinct symptom clusters centered around pain and fever. In the expanded symptom cohort, there were 5,731 visits and six symptom clusters centered around fever, emesis/nausea, fatigue, deep vein thrombosis, pain, and ascites. For patients who newly initiated treatment, there were 1,154 visits and four symptom clusters centered around fever, nausea/emesis, fatigue, and deep vein thrombosis.

CONCLUSION

Uncontrolled symptoms are associated with unplanned acute care. Recognition of the complexity of symptom co-occurrence can drive improved management strategies.

The palliative chemotherapy decision and experiences of South African patients and their families

AIMS

To describe what motivates cancer patients, treated at a private cancer care centre in Port Elizabeth, South Africa, to undergo palliative chemotherapy and how the patients and their families experienced this treatment.

METHODS

A descriptive qualitative design was used. Researchers conducted 22 in-depth interviews with 11 purposively selected patients and 11 family members nominated by the patients. Qualitative content analysis was used to analyse the data.

FINDINGS

The patient participants consisted of two males and nine females between the ages 40 and 79, who had been diagnosed with various cancers. The family members consisted of six husbands, two wives and three sons, with ages ranging from 20 to 79. Three themes arose from the patient data and three from the family data.

CONCLUSION

Hope informed the palliative treatment decision. Despite being told that the chemotherapy would not cure them, patients hoped for additional time and even a cure. The families supported the patient's decision and shared their hopes. The family members were aware of the side effects their loved ones were experiencing, but still experienced the treatment as positive. Giving and receiving support was important and religion, the families and staff and fellow patients at the cancer care centre were identified as sources of support.

Cellular mechanisms of cyclophosphamide-induced taste loss in mice

Many commonly prescribed chemotherapy drugs such as cyclophosphamide (CYP) have adverse side effects including disruptions in taste which can result in loss of appetite, malnutrition, poorer recovery and reduced quality of life. Previous studies in mice found evidence that CYP has a two-phase disturbance in taste behavior: a disturbance immediately following drug administration and a second which emerges several days later. In this study, we examined the processes by which CYP disturbs the taste system by examining the effects of the drug on taste buds and cells responsible for taste cell renewal using immunohistochemical assays. Data reported here suggest CYP has direct cytotoxic effects on lingual epithelium immediately following administration, causing an early loss of taste sensory cells. Types II and III cells in fungiform taste buds appear to be more susceptible to this effect than circumvallate cells. In addition, CYP disrupts the population of rapidly dividing cells in the basal layer of taste epithelium responsible for taste cell renewal, manifesting a disturbance days later. The loss of these cells temporarily retards the system’s capacity to replace Type II and Type III taste sensory cells that survived the cytotoxic effects of CYP and died at the end of their natural lifespan. The timing of an immediate, direct loss of taste cells and a delayed, indirect loss without replacement of taste sensory cells are broadly congruent with previously published behavioral data reporting two periods of elevated detection thresholds for umami and sucrose stimuli. These findings suggest that chemotherapeutic disturbances in the peripheral mechanisms of the taste system may cause dietary challenges at a time when the cancer patient has significant need for well balanced, high energy nutritional intake.
