Symptom prevalence, intensity, and distress in patients with inoperable lung cancer in relation to time of death

Randomized Controlled Trial of a Nurse-Led Brief Behavioral Intervention for Dyspnea in Patients With Advanced Lung Cancer

PURPOSE

In patients with lung cancer, dyspnea is one of the most prevalent and disabling symptoms, for which effective treatments are lacking. We examined the efficacy of a nurse-led brief behavioral intervention to improve dyspnea in patients with advanced lung cancer.

METHODS

Patients with advanced lung cancer reporting at least moderate breathlessness (n = 247) were enrolled in a randomized trial of a nurse-led two-session intervention (focused on breathing techniques, postural positions, and fan therapy) versus usual care. At baseline and weeks 8 (primary end point), 16, and 24, participants completed measures of dyspnea (Modified Medical Research Council Dyspnea Scale [mMRCDS]; Cancer Dyspnoea Scale [CDS]), quality of life (Functional Assessment of Cancer Therapy-Lung [FACT-L]), psychological symptoms (Hospital Anxiety and Depression Scale), and activity level (Godin-Shephard Leisure Time Physical Activity Questionnaire). To examine intervention effects, we conducted analysis of covariance and longitudinal mixed effects models.

RESULTS

The sample (Agemean = 66.15 years; 55.9% female) primarily included patients with advanced non-small cell lung cancer (85.4%). Compared with usual care, the intervention improved the primary outcome of patient-reported dyspnea on the mMRCDS (difference = -0.33 [95% CI, -0.61 to -0.05]) but not the CDS total score at 8 weeks. Intervention patients also reported less dyspnea on the CDS sense of discomfort subscale (difference = -0.59 [95% CI, -1.16 to -0.01]) and better functional well-being per the FACT-L (difference = 1.39 [95% CI, 0.18 to 2.59]) versus the control group. Study groups did not differ in overall quality of life, psychological symptoms, or activity level at 8 weeks or longitudinally over 24 weeks.

CONCLUSION

For patients with advanced lung cancer, a scalable behavioral intervention alleviated the intractable symptom of dyspnea. Further research is needed on ways to enhance intervention effects over the long-term and across additional outcomes.

The relationship between perceived social support, coping style, and the quality of life and psychological state of lung cancer patients

BACKGROUND

Lung cancer has always a cancer that threatens human health. Quality of life also has been an important research topic. psychological state in patients can influence their quality of life, and perceived social support and coping styles are relevant facilitators of Quality of life, but this specific relationship has not been adequately studied. The purpose of this study is focus on discussing the correlation of these four and understanding their potential mediating pathways.

MATERIALS AND METHODS

This is a cross-sectional study. A total of 300 Lung Cancer patients from a cancer hospital in Suzhou were surveyed. The Data was collected using the scales. The collected data was analyzed using SPSS and AMOS software.

RESULTS

The study revealed a significant serial mediation model between perceived social support and coping style: Psychological state regulates patients' coping styles by influencing their perceived social support which ultimately has comprehensive impacts on their quality of life.

CONCLUSION

Based on the empirical results discussed, this study proposes the following suggestion: Provide good online support to form a related social media intervention matrix. meanwhile, expand the patients' social network offline, provide channels for patients to express their troubles outwardly, and regularly assess the patients' psychological status to improve their level of psychosocial adaptation. This will in turn enhance their negative coping strategies towards the disease and strengthen their ability to buffer against it, ultimately promoting a better quality of life for the patients.

Tai Chi and Aerobic Exercise on Cancer-Related Dyspnea in Advanced Lung Cancer Patients: A Randomized Clinical Trial

CONTEXT

Dyspnea, a prevalent and debilitating symptom in patients with advanced lung cancer, negatively affects symptom burden and prognosis. Physical activity has emerged as a promising non-pharmacological intervention for managing dyspnea.

OBJECTIVES

This study compared the effectiveness of two widely-recognized physical activity modalities, namely Tai Chi (TC) and aerobic exercise (AE) for treating dyspnea in patients with advanced lung cancer.

METHODS

Patients with advanced lung cancer (n=226) were randomized into TC, AE, or control groups. There was no baseline dyspnea requirement for patients. The AE group received two 60-minute supervised sessions and home-based exercises per month, the TC group received 60-minute sessions twice weekly, and the control group received exercise guidelines for 16 weeks. The primary outcome (sleep quality) of the study has been previously reported. In this secondary analysis, we focused on dyspnea outcomes, including overall and lung cancer-specific dyspnea. Assessments were conducted at baseline (T0), 16 weeks (T1), and one year (T2).

RESULTS

Compared to the control group, TC significantly improved overall dyspnea at T1 (between-group difference, -8.69; P=0.03) and T2 (between-group difference, -11.45; P=0.01), but not AE. Both AE (between-group difference, -11.04; P=0.01) and TC (between-group difference, -14.19; P<0.001) significantly alleviated lung cancer-specific dyspnea at T2 compared with the control group.

CONCLUSION

Both TC and AE alleviate dyspnea severity in patients with advanced lung cancer, and continuous exercise can yield substantial improvements. Due to its multi-component nature, Tai Chi has a greater effect on dyspnea.

Dyspnea-Related Dimensions And Self-Efficacy: Associations With Well-Being in Advanced Lung Cancer

CONTEXT

Dyspnea is a complex, multidimensional symptom comprising sensory-perceptual, affective, and functional domains that commonly persists in patients with lung cancer and impairs mental health and quality of life (QOL). However, data are lacking on how dyspnea's dimensions or self-efficacy to manage dyspnea are associated with patient outcomes.

OBJECTIVES

To assess the associations of dyspnea dimensions (dyspnea-related sensory-perceptual experience, affective distress, and functional impact) and dyspnea self-efficacy with depression, anxiety, and QOL in patients with advanced lung cancer reporting dyspnea.

METHODS

We conducted a secondary analysis of baseline clinical trial data testing a supportive care intervention for dyspnea. Patients with advanced lung cancer reporting at least moderate dyspnea (≥2 on the Modified Medical Research Council Dyspnea Scale) self-reported dyspnea and patient outcome measures. Hierarchical regressions tested the associations of the dyspnea dimensions with depressive and anxiety symptoms (Hospital Anxiety and Depression Scale) and QOL (Functional Assessment of Cancer Therapy-Lung) while adjusting for variables known to affect these outcomes.

RESULTS

The sensory-perceptual experience of dyspnea (effort) was associated with worse depressive symptoms (b = 0.21, P < 0.01) and QOL (b = -0.53, P = 0.01). Dyspnea self-efficacy was associated with improved depressive (b = -1.26, P < 0.01) and anxiety symptoms (b = -1.72, P < 0.01) and QOL (b = 3.66, P < 0.01). The affective and functional dimensions of dyspnea were not associated with the patient outcomes in the final models.

CONCLUSIONS

Dyspnea-related sensory-perceptual experience and self-efficacy were associated with mental health and QOL outcomes in patients with lung cancer. Examining the individual contributions of dyspnea's multiple dimensions provides a nuanced understanding of its patient impact.

Dyspnea in Oncological Patients: a Brain Teaser

Dyspnea is one of the most common symptoms in oncological patients with greater prevalence in lung cancer and advanced disease states. Causes of dyspnea can be directly or indirectly associated with cancer, anti-neoplastic therapies and comorbidities unrelated to cancer. Routine screening of dyspnea is suggested for all oncological patients by using unidimensional, simple scales and multidimensional tools to capture more domains affected by this symptom and to assess the effectiveness of interventions. The first step in the treatment algorithm of dyspnea is the identification of potentially reversible causes; if no specific cause is depicted, symptomatic treatment with non-pharmacological and pharmacological interventions is suggested. Referral to palliative care and continuous palliative sedation are the last resort in patients with a very limited life expectancy of not more than a few days for symptomatic relief and to decrease of the distress of patients and caregivers.

Systematic review and meta-analysis of the efficacy of benzodiazepines for dyspnea in patients with cancer

OBJECTIVE

the role of benzodiazepines in relieving dyspnea in patients with cancer has not yet been established. This systematic review and meta-analysis aimed to determine the efficacy and safety of benzodiazepines alone or in combination with opioids for dyspnea in patients with cancer.

METHODS

Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and Ichushi-Web were searched for articles published from database inception to 23 September 2019. Studies of benzodiazepines alone or in combination with opioids for dyspnea were included. The primary outcome measure was the relief of dyspnea. The secondary outcome measures were anxiety, somnolence and severe adverse events.

RESULTS

of 505 publications initially identified, two trials and one trial were included in the meta-analysis of midazolam alone and in combination with morphine, respectively. With regard to the relief of dyspnea, midazolam alone showed no significant difference compared with morphine alone, with a relative risk of 0.95 (95% confidence interval: 0.47-1.89). Meanwhile, midazolam plus morphine was significantly more effective than morphine alone, with a relative risk of 1.33 (95% confidence interval: 1.02-1.75). For anxiety relief, a meta-analysis could not be performed because of insufficient data. The incidence of somnolence and severe adverse events was not significantly different between the experimental and control groups for either midazolam alone or in combination with morphine.

CONCLUSIONS

benzodiazepines alone do not significantly improve dyspnea compared with opioids alone, but a combination of benzodiazepines and opioids may be more effective. Evidence from randomized controlled trials focusing on patients with cancer has not been generated in recent years. Further appropriately designed randomized controlled trials are required.

The burden and impact of chronic cough in severe disease

PURPOSE OF REVIEW

Chronic cough is common in severe diseases, such as COPD, interstitial lung disease, lung cancer and heart failure, and has a negative effect on quality of life. In spite of this, patients with cough sometimes feel their cough is neglected by healthcare workers. This review aims to briefly describe cough mechanisms, highlight the burden chronic cough can be for the individual, and the clinical impact of chronic cough.

RECENT FINDINGS

Chronic cough is likely caused by different mechanisms in different diseases, which may have therapeutic implications. Chronic cough, in general, has a significant negative effect on quality of life, both with and without a severe comorbid disease. It can lead to social isolation, recurrent depressive episodes, lower work ability, and even conditions such as urinary incontinence. Cough may also be predictive of more frequent exacerbations among patients with COPD, and more rapid lung function decline in idiopathic pulmonary fibrosis. Cough is sometimes reported by patients to be underappreciated by healthcare.

SUMMARY

Chronic cough has a significant negative impact on quality of life, irrespective of diagnosis. Some differences are seen between patients with and without severe disease. Healthcare workers need to pay specific attention to cough, especially patients with severe disease.

Prophylaxis and treatment of cancer-related dyspnea with pharmacologic agents: A systematic review and network meta-analysis

INTRODUCTION

Cancer-related dyspnea is a common symptom in patients with cancer. It has also been reported to be a predictor of poorer prognosis, which can then change clinical treatment and advance care planning. Currently, no definitive recommendation for pharmacologic agents for cancer-related dyspnea exists. The aim of this systematic review and network meta-analysis is to compare pharmacologic agents for the prophylaxis and treatment of cancer-related dyspnea.

METHODS

A search was conducted in the databases of PubMed, Embase, and Cochrane CENTRAL through May 2021. Standardized mean differences (SMDs), as reported by studies or calculated from baseline and follow-up dyspnea scores, were amalgamated into a summary SMD and 95% confidence interval (CI) using a restricted maximum likelihood multivariate network meta-analysis.

RESULTS

Twelve studies were included in this review; six reported on prophylaxis of exertional dyspnea, five on treatment of everyday dyspnea, and one on treatment of episodic dyspnea. Morphine sulfate was better at controlling everyday dyspnea than placebo (SMD 1.210; 95% CI: 0.415-2.005). Heterogeneity in study design and comparisons, however, led to some concerns with the underlying consistency assumption in network meta-analysis design.

CONCLUSION

Optimal pharmacologic interventions for cancer-related dyspnea could not be determined based on this analysis. Further trials are needed to report on the efficacy of pharmacologic interventions for the prophylaxis and treatment of cancer-related dyspnea.

Assessment of total pain in people in oncologic palliative care: integrative literature review

The promotion of comfort and quality of life of people with cancer in palliative care requires flawless evaluation and management of pain, understood in its multidimensionality and integrality. The objective of this study was to present an overview of the scientific production referring to evaluation of the pain and total pain of patients with advanced cancer in palliative care. The study involved an integrative literature review, searching the databases PubMed, Embase, Cinahl, Lilacs and Web of Science using the descriptors 'Total Pain', 'Cancer Pain', 'Pain', 'Symptom Assessment', 'Pain Measurement', 'Pain Evaluation', 'Neoplasms', 'Cancer', 'Tumor', 'Palliative Care', 'Hospice Care', and 'Terminal Care'. To select the studies, the authors used the reference manager Mendeley and the application Rayyan™, as well as blind and independent peer review. Twenty-two articles were selected, published between 2002 and 2020 in different countries, and classified into two thematic units: 'Physical, social, emotional, and spiritual factors related to pain in cancer' (N = 13) and 'Importance of the overall evaluation and multidisciplinary team in the management of pain' (N = 9). Advanced cancer is associated with high mortality, a decline in health status, the presence of pain, and complex psychosocial concerns. Pain and symptoms in patients in palliative care should be evaluated as a whole and controlled thorough the work of an interdisciplinary team. The qualitative synthesis of the results demonstrates that most of the evaluated studies have a mixed nature; there are significant methodological differences among them and a low level of evidence in studies relating to the subject of pain evaluation in palliative care.

Effect of heated humidified high-flow nasal cannula (HFNC) oxygen therapy in dyspnea patients with advanced cancer, a randomized controlled clinical trial

PURPOSE

Heated humidified high-flow nasal cannula (HFNC) oxygen therapy is one of the most important oxygen therapy methods, which are commonly applied to relieve dyspnea in advanced cancer patients. Our study aims to observe the efficacy and safety of HFNC oxygen therapy on dyspnea patients with advanced cancer and explore the clinical application.

METHODS

Sixty subjects with advanced cancer requiring oxygen therapy from a grade 3, class A hospital in China were recruited and randomized (1:1) to traditional nasal catheter oxygen therapy or HFNC. Primary outcomes were dyspnea, oral dryness, and sleep condition, which were recorded after 72-h treatment. Secondary outcomes were heart rate (HR), respiration rate (RR), S_pO₂, P_aO₂, and P_aCO₂, which were recorded after 2, 6, 24, and 72 h treatment.

RESULTS

Seventy-two hours after treatment, there were significant improvements in all primary outcomes (P < 0.001). P_aO₂ and RR were statistically changed 2 h after HFNC treatment (P < 0.001). P_aCO₂ and HR were statistically changed 24 h after HFNC treatment (P < 0.001).

CONCLUSION

HFNC oxygen therapy has good effect, high safety, and is easy to be accepted by dyspnea patients with advanced cancer. It can be used as the first choice of oxygen therapy for these patients and has broad clinical prospects.

TRIAL REGISTRATION

This work was retrospectively registered in the Chinese Clinical Trials Registry (ChiCTR2100049582) on August 4, 2021.

Psychological distress prior to surgery is related to symptom burden and health status in lung cancer survivors

PURPOSE

Patients with lung cancer experience a variety of distressing symptoms which could adversely affect quality of life. The aim of this study was to determine whether psychological distress prior to surgery is associated to health status and symptom burden in lung cancer survivors.

METHODS

A longitudinal observational study with 1-year follow-up was carried out. Health status was measured by the WHO Disability Assessment Scale (WHO-DAS 2.0), the Euroqol-5 dimensions (EQ-5D) and the Pittsburgh Sleep Quality Index (PSQI). Symptoms severity included dyspnoea (Multidimensional Profile of Dyspnoea); pain (Brief Pain Inventory); fatigue (Fatigue Severity Scale); and cough (Leicester Cough Questionnaire).

RESULTS

One hundred seventy-four lung cancer patients were included. Patients in the group with psychological distress presented a worse self-perceived health status, functionality and sleep quality. The group with psychological distress also presented higher dyspnoea, fatigue and pain.

CONCLUSION

Patients with psychological distress prior surgery present with a greater symptom burden and a poorer self-perceived health status, lower functionality and sleep quality, than patients without distress 1 year after the lung resection.

Trajectory of health-related quality of life during the last year of life in patients with advanced non-small-cell lung cancer

BACKGROUND

The aims of this study were to assess the trajectory of health-related quality of life (HRQOL) during the last year of life in patients with advanced non-small-cell lung cancer (NSCLC) and to explore when and to what degree deterioration of symptoms and physical functioning accelerate towards the end of life.

METHODS

Data from two RCTs of first-line chemotherapy in advanced NSCLC was analyzed. HRQOL was assessed repeatedly using the EORTC QLQ-C30 and LC13. Changes in HRQOL scores were investigated relative to the time of death.

RESULTS

The study sample included 730 patients, with a median of four HRQOL assessments per patient (range 1-9). Fatigue, dyspnea, appetite loss, and cough were the most pronounced symptoms in all phases of the disease trajectory. The deterioration rates of global quality of life, physical function, and key symptoms were relatively slow until 4 months before death. Then, the decline accelerated, and for physical function, fatigue, and dyspnea, there was a very rapid decline in the last 2 months.

CONCLUSIONS

Patients with advanced NSCLC experience a high symptom burden that worsens over time, especially in the last 4 months. Regular symptom monitoring may help identify where patients are in the disease trajectory, serve as a trigger for changes in anticancer and symptomatic treatment, and facilitate discussions about end-of-life care.

Acupuncture for breathlessness in advanced cancer: a protocol for systematic review and meta-analysis with trial sequential analysis

INTRODUCTION

Breathlessness in advanced cancer, a frequent multicomponent and debilitating disorder, severely reduces function and quality of patients' life. Multiple studies have shown that non-pharmacological therapies can effectively palliate breathlessness in advanced cancer. However, no systematic review has investigated the application of acupuncture, as a non-pharmacological treatment, for breathlessness in advanced cancer. A systematic review will be conducted to summarise evidence supporting the efficacy and safety of acupuncture as a therapeutic option for breathlessness in advanced cancer based on existing randomised controlled trials (RCTs).

METHODS

RCTs will be retrieved from nine scientific databases, including the MEDLINE via PubMed, Web of Science via the Web of Knowledge, Embase via Ovid, the Cochrane Central Register of Controlled Trials via the Cochrane Library, and Allied and Complementary Medicine Database via EBSCO, China National Knowledge Infrastructure, Wanfang Database, VIP Database, Chinese Biomedical Literature Database; three clinical registry platforms, including the WHO International Clinical Trials Registry Platform, NIH Clinical trials.gov and Chinese Clinical Trial Registry, as well as from other sources. Studies published since inception of these databases to 1 August 2021 will be retrieved. Search terms will include breathlessness, cancer, acupuncture and RCT. Two investigators will independently select and extract data from RCTs and assess the risk of bias. The primary outcome, which is alleviation of breathlessness, will be assessed. Meta-analysis will be performed using RevMan V.5.4 and STATA V.15.0. The TSA 0.9.5.10 β software will be used to conduct trial sequential analysis. Finally, the quality of evidence from RCTs will be assessed using the Grading of Recommendations Assessment, Development and Evaluation System tool.

ETHICS AND DISSEMINATION

Results will be disseminated through peer-reviewed journals or conference reports. Since this study involves acquisition of secondary data, ethical approval requirements will be waived.

Automated model versus treating physician for predicting survival time of patients with metastatic cancer

OBJECTIVE

Being able to predict a patient's life expectancy can help doctors and patients prioritize treatments and supportive care. For predicting life expectancy, physicians have been shown to outperform traditional models that use only a few predictor variables. It is possible that a machine learning model that uses many predictor variables and diverse data sources from the electronic medical record can improve on physicians' performance. For patients with metastatic cancer, we compared accuracy of life expectancy predictions by the treating physician, a machine learning model, and a traditional model.

MATERIALS AND METHODS

A machine learning model was trained using 14 600 metastatic cancer patients' data to predict each patient's distribution of survival time. Data sources included note text, laboratory values, and vital signs. From 2015-2016, 899 patients receiving radiotherapy for metastatic cancer were enrolled in a study in which their radiation oncologist estimated life expectancy. Survival predictions were also made by the machine learning model and a traditional model using only performance status. Performance was assessed with area under the curve for 1-year survival and calibration plots.

RESULTS

The radiotherapy study included 1190 treatment courses in 899 patients. A total of 879 treatment courses in 685 patients were included in this analysis. Median overall survival was 11.7 months. Physicians, machine learning model, and traditional model had area under the curve for 1-year survival of 0.72 (95% CI 0.63-0.81), 0.77 (0.73-0.81), and 0.68 (0.65-0.71), respectively.

CONCLUSIONS

The machine learning model's predictions were more accurate than those of the treating physician or a traditional model.

National Study of Pain Medicine Access Among Māori and Non-Māori Patients With Lung Cancer in New Zealand

PURPOSE

Pain is among the most common and consequential symptoms of cancer, particularly in the context of lung cancer. Māori have extremely high rates of lung cancer, and there is evidence that Māori patients with lung cancer are less likely to receive curative treatment and more likely to receive palliative treatment and to wait longer for their treatment than non-Māori New Zealanders. The extent to which Māori patients with lung cancer are also less likely to have access to pain medicines as part of their supportive care remains unclear.

METHODS

Using national-level Cancer Registry and linked health records, we describe access to subsidized pain medicines among patients with lung cancer diagnosed over the decade spanning 2007-2016 and compare access between Māori and non-Māori patients. Descriptive and logistic regression methods were used to compare access between ethnic groups.

RESULTS

We observed that the majority of patients with lung cancer are accessing some form of pain medicine and there do not appear to be strong differences between Māori and non-Māori in terms of overall access or the type of pain medicine dispensed. However, Māori patients appeared more likely than non-Māori to first access pain medicines within 2 weeks before their death and commensurately less likely to access them more than 24 weeks before death.

CONCLUSION

Given the plausibility that there are differences in first access to pain medicines (particularly opioid medicines) among Māori approaching end of life, further investigation of the factors contributing to this disparity is required.

Efficacy and safety of acupuncture combined with analgesics on lung cancer pain: A protocol for systematic review and meta-analysis

BACKGROUND

Lung cancer (LC) is the malignant tumor with the highest incidence in the world, and treatment methods include surgery, radiotherapy, chemotherapy, and immunotherapy. Cancer pain is a common symptom in patients with LC, and the clinical treatment is to relieve it with analgesics. Acupuncture can relieve cancer pain. This study aims to systematically study the efficacy and safety of acupuncture combined with analgesics on cancer pain in patients with LC.

METHODS

From the beginning to April 2021, search Medline, Embase, Cochrane Central Controlled Trials Register (Central), China National Knowledge Infrastructure (CNKI), Wanfang Database, China Biomedical Literature Database (CBM), and Chinese Science Journal Database (VIP database). Search the international clinical trial registration platform and the Chinese clinical trial registration platform to find ongoing or unpublished trials. The main outcome indicator is the total effective rate of analgesia, and the secondary outcome indicator is pain intensity score and adverse reactions. The RevMan 5.4 software will be used for statistical analysis.

RESULTS

This study will provide the latest evidence for acupuncture combined with analgesics to relieve LC pain.

CONCLUSION

The conclusion of this study is to evaluate the effectiveness and safety of acupuncture combined with analgesics in alleviating LC pain.

The Use of Herbal Therapy to Improve the Quality of Life among Cancer Patients in the Southern Region of Peninsular Malaysia

Objective:

To investigate the impact of herbal therapy on the quality of life (QoL) among cancer patients and to evaluate the relationship of QoL with age, gender, cancer stage, cancer type, and history of conventional treatment.

Methodology:

A prospective study was targeted on cancer patients receiving herbal therapy from a Traditional and Complementary Medicine (T&CM) clinic in a public hospital from 1st January 2016 to 31st August 2018. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTCQLQ-C30) was distributed to the patients prior to herbal therapy (baseline) and after the sixth and twelfth week of herbal therapy. Socio-demographic and clinical data were collected and analyzed using SPSS version 16.

Results:

The majority of the patients were females (60.0%) and were from the Chinese ethnic group (77.4%) with a mean age of 58.72 ± 12.17 years. Approximately 42.4% of patients were in advanced cancer stages at the time of study and 60.7% of patients had undergone radiotherapy before receiving herbal therapy. The most commonly prescribed herbs were Bai Hua She She Cao (90.6%) and Zhen Ren Huo Ming Yin (57.6%). Significant differences in mean score were observed in global health status, overall functional scales, and symptom scales after the sixth and twelfth week of receiving herbal therapy. QoL in terms of global health status and overall functional scales improved with higher scores while symptom scales recorded a lower score after twelve weeks of receiving herbal therapy in the T&CM clinic. Herbal therapy has a significant effect (p < 0.05) on the improvement of QoL of cancer patients. However, gender, cancer stage, cancer type, age, history of radiotherapy, and history of chemotherapy has no effect (p > 0.05).

Conclusion:

Herbal therapy did improve the QoL of cancer patients in the southern region of Peninsular Malaysia.

Management of Dyspnea in Advanced Cancer: ASCO Guideline

PURPOSE

To provide guidance on the clinical management of dyspnea in adult patients with advanced cancer.

METHODS

ASCO convened an Expert Panel to review the evidence and formulate recommendations. An Agency for Healthcare Research and Quality (AHRQ) systematic review provided the evidence base for nonpharmacologic and pharmacologic interventions to alleviate dyspnea. The review included randomized controlled trials (RCTs) and observational studies with a concurrent comparison group published through early May 2020. The ASCO Expert Panel also wished to address dyspnea assessment, management of underlying conditions, and palliative care referrals, and for these questions, an additional systematic review identified RCTs, systematic reviews, and guidelines published through July 2020.

RESULTS

The AHRQ systematic review included 48 RCTs and two retrospective cohort studies. Lung cancer and mesothelioma were the most commonly addressed types of cancer. Nonpharmacologic interventions such as fans provided some relief from breathlessness. Support for pharmacologic interventions was limited. A meta-analysis of specialty breathlessness services reported improvements in distress because of dyspnea.

RECOMMENDATIONS

A hierarchical approach to dyspnea management is recommended, beginning with dyspnea assessment, ascertainment and management of potentially reversible causes, and referral to an interdisciplinary palliative care team. Nonpharmacologic interventions that may be offered to relieve dyspnea include airflow interventions (eg, a fan directed at the cheek), standard supplemental oxygen for patients with hypoxemia, and other psychoeducational, self-management, or complementary approaches. For patients who derive inadequate relief from nonpharmacologic interventions, systemic opioids should be offered. Other pharmacologic interventions, such as corticosteroids and benzodiazepines, are also discussed. Additional information is available at www.asco.org/supportive-care-guidelines .

High-Flow Nasal Cannula Therapy for Exertional Dyspnea in Patients with Cancer: A Pilot Randomized Clinical Trial

BACKGROUND

Exertional dyspnea is common in patients with cancer and limits their function. The impact of high-flow nasal cannula on exertional dyspnea in nonhypoxemic patients is unclear. In this double-blind, parallel-group, randomized trial, we assessed the effect of flow rate (high vs. low) and gas (oxygen vs. air) on exertional dyspnea in nonhypoxemic patients with cancer.

PATIENTS AND METHODS

Patients with cancer with oxygen saturation >90% at rest and exertion completed incremental and constant work (80% maximal) cycle ergometry while breathing low-flow air at 2 L/minute. They were then randomized to receive high-flow oxygen, high-flow air, low-flow oxygen, or low-flow air while performing symptom-limited endurance cycle ergometry at 80% maximal. The primary outcome was modified 0-10 Borg dyspnea intensity scale at isotime. Secondary outcomes included dyspnea unpleasantness, exercise time, and adverse events.

RESULTS

Seventy-four patients were enrolled, and 44 completed the study (mean age 63; 41% female). Compared with low-flow air at baseline, dyspnea intensity was significantly lower at isotime with high-flow oxygen (mean change, -1.1; 95% confidence interval [CI], -2.1, -0.12) and low-flow oxygen (-1.83; 95% CI, -2.7, -0.9), but not high-flow air (-0.2; 95% CI, -0.97, 0.6) or low-flow air (-0.5; 95% CI, -1.3, 0.4). Compared with low-flow air, high-flow oxygen also resulted in significantly longer exercise time (difference + 2.5 minutes, p = .009), but not low-flow oxygen (+0.39 minutes, p = .65) or high-flow air (+0.63 minutes, p = .48). The interventions were well tolerated without significant adverse effects.

CONCLUSION

Our preliminary findings support that high-flow oxygen improved both exertional dyspnea and exercise duration in nonhypoxemic patients with cancer. (ClinicalTrials.gov ID: NCT02357134).

IMPLICATIONS FOR PRACTICE

In this four-arm, double-blind, randomized clinical trial examining the role of high-flow nasal cannula on exertional dyspnea in patients with cancer without hypoxemia, high-flow oxygen, but not high-flow air, resulted in significantly lower dyspnea scores and longer exercise time. High-flow oxygen delivered by high-flow nasal cannula devices may improve clinically relevant outcomes even in patients without hypoxemia.

Nonpharmacological Interventions for Pain Management in Lung Cancer Patients: A Systematic Review

Background:

The presence of lung cancer is almost always associated with pain, a symptom that causes severe distress in patients. Although many pharmacological methods are available to manage pain in this oncologic population, the medications often cause undesirable sideeffects and inadequate relief. Nonpharmacological interventions can be used as adjuvants to pharmacological interventions in reducing pain and increasing quality of life.

Objectives:

The purpose of this review is to compare the efficacy of nonpharmacological interventions in reducing pain in lung cancer patients.

Materials and Methods:

This is a systematic review study guided by the Preferred Reporting Items of Systematic reviews and Meta-Analysis Protocol. Interventions identified in the present systematic review have been categorized as physical treatment, technologybased, cognitive behavioral, coping, and coaching.

Results:

Results indicate that the nonpharmacological interventions such as physical treatment interventions, selfmanagement and coaching interventions, cognitive behavioral interventions, and technologybased interventions or coping skills interventions had limited and shortterm effects on alleviating pain among the patients. However, previous studies have provided limited evidence regarding nonpharmacologic therapy due to the lack of a comparison group, small sample sizes, and lack of longterm followup periods to determine whether sustained effects are feasible.

Conclusion:

Healthcare professionals should consider additional research on the added advantage of utilizing the nonpharmacological interventions as an adjunct option while managing pain in lung cancer patients.

Palliative care needs and utilisation of different specialist services in the last days of life for people with lung cancer

OBJECTIVES

To (a) compare palliative care needs of lung cancer patients on their final admission to community-based and inpatient palliative care services; and (b) explore whether and how these care needs affect their utilisation of different palliative care services in the last days of life.

METHODS

Descriptive study involving 17,816 lung cancer patients who received the last episode of palliative care from specialist services and died between 1 January 2013 and 31 December 2018.

RESULTS

Both groups of patients admitted to community-based and inpatient palliative care services generally experienced relatively low levels of symptom distress, but high levels of functional impairment and dependency. "Unstable" versus "stable" palliative care phase (Odds ratio = 11.66; 95% Confidence Interval: 9.55-14.24), poorer functional outcomes and severe levels of distress from many symptoms predicted greater likelihood of use of inpatient versus community-based palliative care.

CONCLUSIONS

Most inpatient palliative care admissions are not associated with high levels of symptom severity. To extend the period of home care and rate of home death for people with lung cancer, additional investment is required to improve their access to sufficiently skilled palliative care staff, multi-disciplinary teams and 24-hour home support in community settings.

The role of palliative care in the management of patients with lung cancer

Palliative care (PC) is the care of patients and their families with serious illness and is rapidly becoming an important part of the care of cancer patients. Patients with advanced lung cancer are a highly symptomatic population of patients and clearly experience benefits in quality of life and potentially benefits in overall survival when PC is incorporated early on after diagnosis. However, referrals to PC are still reliant on clinical judgment of patient prognosis and symptom burden. Moving forward, improving the integration of PC and lung cancer care will require more efficient real-time screening of patient symptoms, which may be accomplished through the use of patient-reported outcomes.

A cross sectional study to determine the prevalence of cough and its impact in patients with lung cancer: a patient unmet need

BACKGROUND

There is absence of literature related to cough prevalence and its characteristics in lung cancer patients, with information deriving only from broader symptoms occurrence studies. The aims of this study were to provide a snapshot of the prevalence of all-cause-cough in lung cancer patients and to characterise cough in terms of its impact and severity.

METHODS

A cross-sectional study recruiting consecutive lung cancer patients over a pre-defined period of time and using cough-specific validated tools in a tertiary referral centre in the UK, including a cough severity VAS and the Manchester Cough in Lung Cancer scale (MCLCS).

RESULTS

Data was collected from 202 patients. All-cause cough prevalence was 57% (through VAS) both in the screened (N = 223) and research (N = 202) population or 67% (through the MCLCS), and cough severity was moderate at a mean of 32 mm (in a 100 mm VAS). Age, sex, smoking status, lung cancer histology, stage and comorbidities were not associated with cough prevalence. The only variable associated with lower cough reports was being 'on anticancer treatment'; fewer patients on treatment reported a cough (40%) compared to those off treatment (54%) (p = 0.04). The impact of cough (as measured by MCLCS) was also significant (mean score = 22). About 18% of patients felt moderate/severe distress from their cough and about 15% often or always reported disturbed sleep due to coughing. Half the patients felt their cough warranted treatment.

CONCLUSIONS

Cough is a common symptom in lung cancer with considerable impact on patients' lives. Cough presence and severity should regularly be assessed in clinical practice. There is an urgent need to focus on developing more potent antitussive treatments and improve the management of this complex and distressing symptom.

Quality of life and symptom intensity over time in people with cancer receiving palliative care: Results from the international European Palliative Care Cancer Symptom study

Background

People with advanced cancer experience multiple symptoms during their illness trajectory, which can fluctuate in intensity.

Aim

To describe the course of self-reported quality of life, emotional functioning, physical functioning and symptom intensity over time in cancer patients receiving palliative care.

Design

Longitudinal study with monthly assessments, using the EORTC QLQ-C15-PAL. Data were analysed (1) prospectively, from baseline to ≥8-month follow-up; and (2) retrospectively, by taking death as index date and comparing results from three cross-sectional subsamples at different stages of illness (time to death ≥6, 5–3 and 2–0 months). Linear mixed models were calculated.

Setting/participants

A total of 1739 patients (mean age 66, 50% male) from 30 palliative care centers in 12 countries were included.

Results

In prospective analyses, quality of life, functioning and symptoms–except nausea/vomiting–remained generally stable over time. In retrospective analyses, patients 2–0 months before death reported significantly lower quality of life and physical functioning scores than those 5–3 months before death, who in turn scored lower than those ≥6 months before death, suggesting progressive decline. Emotional functioning remained initially unchanged, but decreased in the last months. Pain, fatigue and appetite loss showed a stable increase in intensity towards death. Dyspnea, insomnia and constipation increased from 5–3 to 2–0 months before death. Nausea/vomiting only increased when comparing those ≥6 months before death with those 2–0 months before death.

Conclusion

While the prospective approach showed predominantly stable patterns for quality of life, functioning and symptom severity throughout study duration, retrospective analyses indicated that deterioration was already apparent before the terminal phase and accelerated close to death. Our findings support the importance of early symptom identification and treatment in this population, and highlight the need for further studies to explore what characterizes those with either lower or higher symptom burden at different time points towards death.

Systemic corticosteroids for the management of cancer-related breathlessness (dyspnoea) in adults

BACKGROUND

Dyspnoea is a common symptom in advanced cancer, with a prevalence of up to 70% among patients at end of life. The cause of dyspnoea is often multifactorial, and may cause considerable psychological distress and suffering. Dyspnoea is often undertreated and good symptom control is less frequently achieved in people with dyspnoea than in people with other symptoms of advanced cancer, such as pain and nausea. The exact mechanism of action of corticosteroids in managing dyspnoea is unclear, yet corticosteroids are commonly used in palliative care for a variety of non-specific indications, including pain, nausea, anorexia, fatigue and low mood, despite being associated with a wide range of adverse effects. In view of their widespread use, it is important to seek evidence of the effects of corticosteroids for the management of cancer-related dyspnoea.

OBJECTIVES

To assess the effects of systemic corticosteroids for the management of cancer-related breathlessness (dyspnoea) in adults.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL, Science Citation Index Web of Science, Latin America and Caribbean Health Sciences (LILACS) and clinical trial registries, from inception to 25 January 2018.

SELECTION CRITERIA

We included randomised controlled trials that included adults aged 18 years and above. We included participants with cancer-related dyspnoea when randomised to systemic corticosteroids (at any dose) administered for the relief of cancer-related dyspnoea or any other indication, compared to placebo, standard or alternative treatment.

DATA COLLECTION AND ANALYSIS

Five review authors independently assessed trial quality and three extracted data. We used means and standard deviations for each outcome to report the mean difference (MD) with 95% confidence interval (CI). We assessed the risk of bias and quality of evidence using GRADE. We extracted primary outcomes of sensory-perceptual experience of dyspnoea (intensity of dyspnoea), affective distress (quality of dyspnoea) and symptom impact (burden of dyspnoea or impact on function) and secondary outcomes of serious adverse events, participant satisfaction with treatment and participant withdrawal from trial.

MAIN RESULTS

Two studies met the inclusion criteria, enrolling 157 participants (37 participants in one study and 120 in the other study), of whom 114 were included in the analyses. The studies compared oral dexamethasone to placebo, followed by an open-label phase in one study. One study lasted seven days, and the duration of the other study was 15 days.We were unable to conduct many of our predetermined analyses due to different agents, dosages, comparators and outcome measures, routes of drug delivery, measurement scales and time points. Subgroup analysis according to type of cancer was not possible.Primary outcomesWe included two studies (114 participants) with data at one week in the meta-analysis for change in dyspnoea intensity/dyspnoea relief from baseline. Corticosteroid therapy with dexamethasone resulted in an MD of lower dyspnoea intensity compared to placebo at one week (MD -0.85 lower dyspnoea (scale 0-10; lower score = less breathlessness), 95% CI -1.73 to 0.03; very low-quality evidence), although we were uncertain as to whether corticosteroids had an important effect on dyspnoea as results were imprecise. We downgraded the quality of evidence by three levels from high to very low due to very serious study limitations and imprecision.One study measured affective distress (quality of dyspnoea) and results were similar between groups (29 participants; very low-quality evidence). We downgraded the quality of the evidence three times for imprecision, inconsistency, and serious study limitations.Both studies assessed symptom impact (burden of dyspnoea or impact on function) (113 participants; very low-quality evidence). In one study, it was unclear whether dexamethasone had an effect on dyspnoea as results were imprecise. The second study showed more improvement for physical well-being scores at days eight and 15 in the dexamethasone group compared with the control group, but there was no evidence of a difference for FACIT social/family, emotional or functional scales. We downgraded the quality of the evidence three times for imprecision, inconsistency, and serious study limitations.Secondary outcomesDue to the lack of homogenous outcome measures and inconsistency in reporting, we could not perform quantitative analysis for any secondary outcomes. In both studies, the frequency of adverse events was similar between groups, and corticosteroids were generally well tolerated. The withdrawal rates for the two studies were 15% and 36%. Reasons for withdrawal included lost to follow-up, participant or carer (or both) refusal, and death due to disease progression. We downgraded the quality of evidence for these secondary outcomes by three levels from high to very low due to serious study limitations, inconsistency and imprecision.Neither study examined participant satisfaction with treatment.

AUTHORS' CONCLUSIONS

There are few studies assessing the effects of systemic corticosteroids on cancer-related dyspnoea in adults with cancer. We judged the evidence to be of very low quality that neither supported nor refuted corticosteroid use in this population. Further high-quality studies are needed to determine if corticosteroids are efficacious in this setting.

Altered Hypothalamus-Pituitary-Adrenal Axis Function: A Potential Underlying Biological Pathway for Multiple Concurrent Symptoms in Patients With Advanced Lung Cancer

OBJECTIVE

Patients with advanced cancer commonly experience multiple symptoms that present as groups or clusters. The present study aimed to examine whether hypothalamus-pituitary-adrenal (HPA) axis dysfunction underlies the concurrent multiple symptoms in patients with advanced cancer.

METHODS

Patients' cortisol levels were determined in saliva samples collected after awakening (0, 30, and 60 minutes after awakening) and at nighttime (21:00-22:00 PM) from 46 patients with lung cancer (15.2% women), with a mean (standard deviation) age of 64.3 (9.2) years and 47 healthy participants (53.2% women; age = 62.0 [4.6] years). Cancer-related symptoms were measured using the M.D. Anderson Symptom Inventory (MDASI).

RESULTS

Compared with healthy participants, patients showed a significantly reduced cortisol awakening response (F(1,364) = 46.2, p < .001) and had flatter diurnal slope of cortisol (larger β values) (mean [standard error of the mean] = -0.64 [0.06] versus -0.18 [0.05], p < .001). Altered HPA axis function was significantly and adversely associated with performance status and burden of symptoms (all p values < .01). However, each MDASI item varied widely in the degree of association with the HPA axis function. Hierarchical clustering analysis based on Spearman's rank correlation with complete linkage identified that nausea was clustered with vomiting, numbness, and dry mouth, whereas the other nine MDASI core symptoms associated with altered HPA axis function were clustered together.

CONCLUSIONS

Altered HPA axis function may be a possible biological pathway that can explain the concurrence of core symptoms in patients with advanced lung cancer.

Symptoms of Posttraumatic Stress Disorder and Associated Risk Factors in Patients With Lung Cancer: A Longitudinal Observational Study

PURPOSE

This study aimed to measure symptoms of posttraumatic stress disorder (PTSD) in Chinese patients following a new diagnosis of lung cancer. Secondary aims were to explore factors at diagnosis that may predict PTSD symptoms at 6 months.

METHODS

This was a prospective longitudinal observational study that included 93 patients with newly diagnosed lung cancer. PTSD symptomology was assessed using the PTSD Checklist Civilian Version (PCL-C) and health-related quality of life (HRQoL) was assessed with the European Organisation for the Research and Treatment of Cancer questionnaire. Measures were completed at diagnosis and 6 months.

RESULTS

No patient had PTSD at baseline or 6 months as measured by a score of ⩾50 in the PCL-C. However, at diagnosis, 44% of patients had "mild" symptoms of PTSD. At 6 months, 64% of patients had "mild" and 8% had "moderate" PTSD symptoms. PTSD symptom scores significantly worsened over 6 months (mean difference [95% CI] = 7.2 [5.4 to 9.0]). Six months after diagnosis, higher PTSD scores were seen in people who at diagnosis were younger ( P = .003), had a lower smoking pack history ( P = .012), displayed less sedentary behavior ( P < .005), or initially had worse cancer symptoms, including fatigue ( P = .001) and poorer HRQoL ( P = .004).

CONCLUSIONS

Mild PTSD symptoms are common in patients with lung cancer 6 months after treatment; however, a full diagnosis of PTSD is uncommon. Screening for PTSD symptoms may be considered for at-risk patients with newly diagnosed lung cancer.

Cough in Patients With Lung Cancer: A Longitudinal Observational Study of Characterization and Clinical Associations

BACKGROUND

Cough is common in patients with lung cancer, and current antitussive treatments are suboptimal. There are little published data describing cough in patients with lung cancer or work assessing clinical associations. The aim of this study is to fill that gap.

METHODS

This was a longitudinal prospective observational single-cohort study over 60 days. Patients were assessed through self-reported validated scales and, in a subsample, ambulatory cough monitoring at study entry (day 0), day 30, and day 60.

RESULTS

At study entry, 177 patients were included and 153 provided data at day 60. The median duration of cough was 52 weeks (interquartile range, 8.5-260). Cough was described as severe enough to warrant treatment in 62% of the patients. Depending on the scale used, performance status was associated with both cough severity and cough impact (P < .001) at study entry, whereas higher cough severity at study entry was associated with female sex (P = .02), asthma (P = .035), and reflux disease (P < .001). Cough impact at study entry was additionally associated with experiencing nausea (P = .018). Cancer characteristics (ie, cancer stage, histology) were not associated with cough severity nor cough impact; neither was smoking or COPD.

CONCLUSIONS

This is the first study to describe characteristics of cough in patients with lung cancer and to identify clinical associations that may be relevant for its treatment. Our data suggest that cough is a frequent and distressing symptom and an unmet clinical need. Its association with gastrointestinal symptoms in this study may improve our understanding of pathophysiology and therapeutic options for cough occurring in patients with lung cancer.

Pattern and Predictors of Outpatient Palliative Care Referral Among Thoracic Medical Oncologists

BACKGROUND

There is significant variation in access to palliative care. We examined the pattern of outpatient palliative care referral among thoracic medical oncologists and identified oncologist characteristics associated with greater referral.

MATERIALS AND METHODS

We retrieved data on all patients who died of advanced thoracic malignancies at our institution between January 1, 2007, and December 31, 2012. Using median as a cutoff, we defined two groups (high-referring and low-referring oncologists) based on their frequency of referral. We examined various oncologist- and patient-related characteristics associated with outpatient referral.

RESULTS

Of 1,642 decedents, 444 (27%) had an outpatient palliative care referral. The median proportion of referral among 26 thoracic oncologists was 30% (range 9%-45%; median proportion of high-referring 37% vs. low-referring 24% when divided into two groups at median). High-referring oncologists were significantly younger (age 45 vs. 56) than low-referring oncologists; they were also significantly more likely to refer patients earlier (median interval between oncology consultation and palliative care consultation 90 days vs. 170 days) and to refer those without metastatic disease (7% vs. 2%). In multivariable mixed-effect logistic regression, younger oncologists (odds ratio [OR] = 0.97 per year increase, 95% confidence interval [CI] 0.95-0.995), younger patients (OR = 0.98 per year increase, 95% CI 0.97-0.99), and nonmetastatic disease status (OR = 0.48, 95% CI 0.29-0.78) were significantly associated with outpatient palliative care referral.

CONCLUSION

The pattern of referral to outpatient palliative care varied widely among thoracic oncologists. Younger oncologists were not only referring a higher proportion of patients, but also referring patients earlier in the disease trajectory.

IMPLICATIONS FOR PRACTICE

This retrospective cohort study found that younger thoracic medical oncologists were significantly more likely to refer patients to outpatient palliative care and to do so earlier in the disease trajectory compared with older oncologists, even after adjusting for other known predictors such as patient demographics. The findings highlight the role of education to standardize palliative care access and imply that outpatient palliative care referral is likely to continue to increase with a shifting oncology workforce.

Prevalence of Physical Problems Detected by the Distress Thermometer and Problem List in Patients With Myeloproliferative Disorders

Background: Patients with myeloproliferative neoplasms (MPNs) can have a severe physical symptom burden over an extended disease trajectory that contributes to decreased quality of life. Few studies, however, have characterized which patients most frequently consider physical symptoms a problem. This study describes the physical symptoms of patients with MPNs and the relationship of these symptoms to patient characteristics. Methods: Patients with MPNs (N=117) completed questionnaires in a dedicated academic medical center MPN clinic. Patients reported demographics (age, race/ethnicity, sex, marital status, employment status), disease characteristics (MPN type, time with MPN), and whether they were bothered by any of 22 variables in the "Physical Problems" list in the Distress Thermometer and Problem List (DT&PL). Results: The median number of physical problems endorsed by patients was 2 (median, 2.26; SD, 3.18), with a range from 0 to 20. Two-fifths endorsed no physical problems, one-fifth endorsed 1 problem, and two-fifths endorsed ≥2 problems, with fatigue (35.5%), sleep (27.1%), pain (21.5%), dry skin/pruritus (18.7%), and memory/concentration (16.8%) being the most commonly reported. Non-Caucasian participants reported more problems with sleep (P=.050), pain (P=.016), and tingling (P=.026). Patients with polycythemia vera (PV) reported more issues with tingling (P=.046) and sexual problems (P=.032). Conclusions: Patients with MPNs are more likely to report physical symptom bother than to report no bother with multiple physical problems on the DT&PL. Patients of minority race/ethnicity and those with PV, however, showed heightened prevalence of physical problems-characteristics which may be used to triage patients for more intensive symptom management.

A Psychometric Evaluation of the Chinese Version of the M.D. Anderson Symptom Inventory-Heart Failure in Chinese Cancer Patients With Concurrent Heart Failure

PURPOSE

The purpose of the study was to translate the M.D. Anderson Symptom Inventory-Heart Failure (MDASI-HF), a specific instrument to assess symptoms in cancer patients with concurrent heart failure (HF), into Mandarin Chinese and to examine its psychometric properties in Chinese cancer patients.

DESIGN

A translation and psychometric evaluation design was used.

METHODS

The translation of the MDASI-HF into Mandarin Chinese followed Brislin's model with the four steps: translation, monolingual assessment, backward translation, and comparison. The Chinese version MDASI-HF was tested among 135 cancer patients with concurrent HF from a cancer hospital in Tianjin, China. Psychometric properties of content validity, internal consistency, test- retest reliability, concurrent validity, and sensitivity of the instrument were evaluated.

FINDINGS

The Cronbach's α was .913 for the core items, .835 for the HF items, and .897 for the interference items. The test-retest reliability was satisfactory with intraclass coefficients > .9 and content validity index was .94. The Chinese version MDASI-HF was significantly correlated with the Eastern Cooperative Oncology Group performance grade (correlation coefficients .456-.600) and the New York Heart Association classification (correlation coefficients .477-.631), indicating the established concurrent validity of the translated instrument.

CONCLUSIONS

The Chinese version MDASI-HF is a valid and reliable instrument to assess the symptoms of Chinese cancer patients with concurrent HF.

CLINICAL RELEVANCE

Symptom assessment and management play important roles in cancer rehabilitation. The Chinese version MDASI-HF can assist appropriate and timely symptom assessment in cancer patients with concurrent HF and can promote communication between healthcare professionals and patients. On the basis of the assessment, the rehabilitation team could provide effective symptom management, evaluate the effectiveness of interventions, and improve patients' quality of life.

Managing, making sense of and finding meaning in advanced illness: a qualitative exploration of the coping and wellbeing experiences of patients with lung cancer

Coping plays an essential role in maintaining the wellbeing of patients with cancer. A number of different coping responses and strategies have been identified in the literature. The value and relevance of meaning based coping theory has also been emphasised, including Antonovosky's Sense of Coherence (SoC) theory. Ten patients with advanced lung cancer were interviewed up to three times. A total of twenty in depth interviews were carried out, fully transcribed and data were analysed following a methodology of Interpretative Phenomenological Analysis. Three broad domains were identified to categorise the core life concerns of participants; making sense of and managing one's illness; maintaining daily life and relationships and confronting the future. Within these domains multiple coping themes are identified, which to varying degrees help to maintain patient wellbeing and quality of life. This article considers the relevance of SoC theory for understanding the coping experiences of patients with advanced cancer, and identifies resources and factors likely to support patient coping, with implications for health and social care services.

Emotional Problems, Quality of Life, and Symptom Burden in Patients With Lung Cancer

OBJECTIVES

Lung cancer is associated with a greater symptom burden than other cancers, yet little is known about the prevalence of emotional problems and how emotional problems may be related to the physical symptom burden and quality of life in newly diagnosed patients with lung cancer. This study aimed to identify the patient and disease characteristics of patients with lung cancer experiencing emotional problems and to examine how emotional problems relate to quality of life and symptom burden.

PATIENTS AND METHODS

A total of 2205 newly diagnosed patients with lung cancer completed questionnaires on emotional problems, quality of life, and symptom burden.

RESULTS

Emotional problems at diagnosis were associated with younger age, female gender, current cigarette smoking, current employment, advanced lung cancer disease, surgical or chemotherapy treatment, and a lower Eastern Cooperative Oncology Group performance score. Additionally, strong associations were found between greater severity of emotional problems, lower quality of life, and greater symptom burden.

CONCLUSION

Certain characteristics place patients with lung cancer at greater risk for emotional problems, which are associated with a reduced quality of life and greater symptom burden. Assessment of the presence of emotional problems at the time of lung cancer diagnosis provides the opportunity to offer tailored strategies for managing negative mood, and for improving the quality of life and symptom burden management of patients with lung cancer.

Hypnosis for Symptom Control in Cancer Patients at the End-of-Life: A Systematic Review

Hypnosis has been shown to alleviate symptoms and side effects of cancer and its treatment. However, less is known about the use of hypnosis at the end of life in individuals with cancer. Our goal was to systematically review the literature on the use of hypnosis to manage the most common symptoms of end-of-life cancer patients: fatigue, sleep disturbances, pain, appetite loss, and dyspnea. EMBASE, MEDLINE, COCHRANE, PsychINFO, and SCOPUS databases were searched from inception through November 7, 2016. No studies met the inclusion criteria. It appears that hypnosis has never been rigorously tested as a means to ameliorate the most common symptoms in individuals with cancer at the end of their lives. This finding is troubling, as it strongly implies that a population most in need has been largely neglected. However, a clear future research direction is revealed that may have significant clinical impact.

Predictors of the multidimensional symptom experience of lung cancer patients receiving chemotherapy

PURPOSE

Few studies have examined interindividual variability in the symptom experience of lung cancer patients. We aimed to identify the most prevalent, severe, and distressing symptoms, and risk factors associated with increased symptom burden.

METHODS

Lung cancer patients (n = 145) reported occurrence, severity, and distress for 38 symptoms on the Memorial Symptom Assessment Scale 1 week after chemotherapy. Using multidimensional subscales, risk factors for higher global distress, physical, and psychological symptoms were evaluated using simultaneous linear regression.

RESULTS

Mean age was 64.0 years and 56.6% were female. Mean Karnofsky Performance Status score was 79.1 (SD 14.6) and mean Self-Administered Comorbidity Questionnaire score was 7.3 (SD 3.9). The most distressing and prevalent symptom was fatigue. Problems with sexual interest/activity had the highest mean severity rating. Patients with lower functional status (p = 0.001) and higher comorbidity (p = 0.02) reported higher global distress. Similarly, lower functional status (p = 0.003) and higher comorbidity (p = 0.04) were associated with a higher physical symptom burden along with lower body mass index (p = 0.02). Higher psychology symptom burden was associated with lower functional status (p = 0.01), younger age (p = 0.02), non-metastatic disease (p = 0.03), higher number of prior treatments (p = 0.04), and income (p = 0.03).

CONCLUSIONS

Fatigue was the most distressing and prevalent symptom among lung cancer patients receiving chemotherapy. Lower functional status was associated with a higher burden of global distress, physical, and psychological symptoms. Younger age and non-metastatic disease were additional risk factors for increased psychological symptoms. Together, these risk factors can help clinicians identify lung cancer patients at increased need for aggressive symptom management.

Regional Emphysema Score Predicting Overall Survival, Quality of Life, and Pulmonary Function Recovery in Early-Stage Lung Cancer Patients

INTRODUCTION

Pulmonary emphysema is a frequent comorbidity in lung cancer, but its role in tumor prognosis remains obscure. Our aim was to evaluate the impact of the regional emphysema score (RES) on a patient's overall survival, quality of life (QOL), and recovery of pulmonary function in stage I to II lung cancer.

METHODS

Between 1997 and 2009, a total of 1073 patients were identified and divided into two surgical groups-cancer in the emphysematous (group 1 [n = 565]) and nonemphysematous (group 2 [n = 435]) regions-and one nonsurgical group (group 3 [n = 73]). RES was derived from the emphysematous region and categorized as mild (≤5%), moderate (6%-24%), or severe (25%-60%).

RESULTS

In group 1, patients with a moderate or severe RES experienced slight decreases in postoperative forced expiratory volume in 1 second, but increases in the ratio of forced expiratory volume in 1 second to forced vital capacity compared with those with a mild RES (p < 0.01); however, this correlation was not observed in group 2. Posttreatment QOL was lower in patients with higher RESs in all groups, mainly owing to dyspnea (p < 0.05). Cox regression analysis revealed that patients with a higher RES had significantly poorer survival in both surgical groups, with adjusted hazard ratios of 1.41 and 1.43 for a moderate RES and 1.63 and 2.04 for a severe RES, respectively; however, this association was insignificant in the nonsurgical group (adjusted hazard ratio of 0.99 for a moderate or severe RES).

CONCLUSIONS

In surgically treated patients with cancer in the emphysematous region, RES is associated with postoperative changes in lung function. RES is also predictive of posttreatment QOL related to dyspnea in early-stage lung cancer. In both surgical groups, RES is an independent predictor of survival.

The Efficacy of Brucea javanica Oil Emulsion Injection as Adjunctive Therapy for Advanced Non-Small-Cell Lung Cancer: A Meta-Analysis

Purpose. To evaluate the efficacy of Brucea javanica oil emulsion injection (BJOEI) in patients with advanced non-small-cell lung cancer (NSCLC) during chemotherapy. Method. Electronic database of EMBASE and PubMed and the conference proceeding of ASCO, CNKI, CBMdisc, VIP, and Wanfang database were searched to select RCTs comparing BJOEI plus chemotherapy with chemotherapy alone in the treatment of advanced NSCLC, until June 1, 2016. Two reviewers independently performed the analysis according to the inclusion and exclusion criteria. Review Manager 5.3 and STATA 12.0 were employed for data analysis. Result. Twenty-one studies including 2234 cases were included. The pooled result indicated that there were significant differences in ORR (RR = 1.25; 95% CI: 1.14-1.36; P < 0.00001), improvement of QOL (RR = 1.87; 95% CI: 1.63-2.15; P < 0.00001), nausea and vomiting (RR = 0.67; 95% CI: 0.46-0.98; P = 0.04), leukopenia (RR = 0.63; 95% CI: 0.52-0.75; P < 0.00001), but there was no difference in thrombocytopenia (RR = 0.78; 95% CI: 0.49-1.23; P = 0.29). Begg's funnel plot and Egger's test indicated that no publication bias was found. The sensitivity analysis suggested the stability of the pooled result. Conclusion. The addition of BJOEI can enhance efficacy, improve QOL, and decrease incidence of nausea and vomiting and leukopenia for advanced NSCLC patients. However, higher quality RCTs are needed to further confirm this finding.

Increasing Complexity in Rule-Based Clinical Decision Support: The Symptom Assessment and Management Intervention

BACKGROUND

Management of uncontrolled symptoms is an important component of quality cancer care. Clinical guidelines are available for optimal symptom management, but are not often integrated into the front lines of care. The use of clinical decision support (CDS) at the point-of-care is an innovative way to incorporate guideline-based symptom management into routine cancer care.

OBJECTIVE

The objective of this study was to develop and evaluate a rule-based CDS system to enable management of multiple symptoms in lung cancer patients at the point-of-care.

METHODS

This study was conducted in three phases involving a formative evaluation, a system evaluation, and a contextual evaluation of clinical use. In Phase 1, we conducted iterative usability testing of user interface prototypes with patients and health care providers (HCPs) in two thoracic oncology clinics. In Phase 2, we programmed complex algorithms derived from clinical practice guidelines into a rules engine that used Web services to communicate with the end-user application. Unit testing of algorithms was conducted using a stack-traversal tree-spanning methodology to identify all possible permutations of pathways through each algorithm, to validate accuracy. In Phase 3, we evaluated clinical use of the system among patients and HCPs in the two clinics via observations, structured interviews, and questionnaires.

RESULTS

In Phase 1, 13 patients and 5 HCPs engaged in two rounds of formative testing, and suggested improvements leading to revisions until overall usability scores met a priori benchmarks. In Phase 2, symptom management algorithms contained between 29 and 1425 decision nodes, resulting in 19 to 3194 unique pathways per algorithm. Unit testing required 240 person-hours, and integration testing required 40 person-hours. In Phase 3, both patients and HCPs found the system usable and acceptable, and offered suggestions for improvements.

CONCLUSIONS

A rule-based CDS system for complex symptom management was systematically developed and tested. The complexity of the algorithms required extensive development and innovative testing. The Web service-based approach allowed remote access to CDS knowledge, and could enable scaling and sharing of this knowledge to accelerate availability, and reduce duplication of effort. Patients and HCPs found the system to be usable and useful.

Impact of Symptom Clusters on Quality of Life Outcomes in Patients from Japan with Advanced Nonsmall Cell Lung Cancers

OBJECTIVE

Identify symptom clusters based on symptoms experienced by patients with advanced nonsmall cell lung cancers (NSCLCs), and examine the relationship between the symptom clusters and impairment in everyday life and quality of life (QOL).

METHODS

Using the M.D. Anderson Symptom Inventory, 9 symptom items and the QOL Questionnaire (QLQ-C-30) evaluation apparatus from the European Organization for Research and Treatment of Cancer, we evaluated symptom severity, interference in daily life, and QOL. Factor analysis and multiple regression analysis techniques were used.

RESULTS

Sixty patients with advanced NSCLCs seen in pulmonary medicine departments were included in the study. The average age of patients was 64.33 (standard deviation = 11.40). Thirty-six were male and 24 were female. Three symptom clusters were identified as fatigue/anorexia cluster (dry mouth, altered the sense of taste, drowsiness, fatigue/tiredness, and lack of appetite), pain cluster (anxiety, sadness, and pain), numbness cluster (numbness, leg weakness, and distress). The pain cluster had the strongest influence (adjusted R2 = 0.355) on daily life (emotions) while the numbness cluster most strongly affected walking. The fatigue/anorexia cluster explained 22.7% of role function variance. This symptom clustering may be unique among patients with advanced NSCLCs.

CONCLUSIONS

Each of these clusters affected QOL and everyday life with varying degrees of influence. In clinical screening assessments, focusing on symptom clusters could provide tailored management strategies for patients with advanced NSCLCs. These care strategies may improve outcomes specifically for advanced NSCLCs patients.

Dexamethasone for Dyspnea in Cancer Patients: A Pilot Double-Blind, Randomized, Controlled Trial

CONTEXT

Dexamethasone is often used to treat dyspnea in cancer patients, but evidence is lacking.

OBJECTIVES

We determined the feasibility of conducting a randomized trial of dexamethasone in cancer patients and estimated the efficacy of dexamethasone in the treatment of dyspnea.

METHODS

In this double-blind, randomized, controlled trial, patients with dyspnea ≥4 were randomized to receive either dexamethasone 8 mg twice daily × four days then 4 mg twice daily × three days or placebo for seven days, followed by an open-label phase for seven days. We documented the changes in dyspnea (0-10 numeric rating scale), spirometry measures, quality of life, and toxicities.

RESULTS

A total of 41 patients were randomized and 35 (85%) completed the blinded phase. Dexamethasone was associated with a significant reduction in dyspnea numeric rating scale of -1.9 (95% CI -3.3 to -0.5, P = 0.01) by Day 4 and -1.8 (95% CI -3.2 to -0.3, P = 0.02) by Day 7. In contrast, placebo was associated with a reduction of -0.7 (95% CI -2.1 to 0.6, P = 0.38) by Day 4 and -1.3 (95% CI -2.4 to -0.2, P = 0.03) by Day 7. The between-arm difference was not statistically significant. Drowsiness improved with dexamethasone. Dexamethasone was well tolerated with no significant toxicities.

CONCLUSION

A double-blind, randomized, controlled trial of dexamethasone was feasible with a low attrition rate. Our preliminary data suggest that dexamethasone may be associated with rapid improvement in dyspnea and was well tolerated. Further studies are needed to confirm our findings.

Update on Prevalence of Pain in Patients With Cancer: Systematic Review and Meta-Analysis

CONTEXT

Cancer pain has a severe impact on quality of life and is associated with numerous psychosocial responses. Recent studies suggest that treatment of cancer pain has improved during the last decade.

OBJECTIVES

The aim of this review was to examine the present status of pain prevalence and pain severity in patients with cancer.

METHODS

A systematic search of the literature published between September 2005 and January 2014 was performed using the databases PubMed, Medline, Embase, CINAHL, and Cochrane. Articles in English or Dutch that reported on the prevalence of cancer pain in an adult population were included. Titles and abstracts were screened by two authors independently, after which full texts were evaluated and assessed on methodological quality. Study details and pain characteristics were extracted from the articles with adequate study quality. Prevalence rates were pooled with meta-analysis; meta-regression was performed to explore determinants of pain prevalence.

RESULTS

Of 4117 titles, 122 studies were selected for the meta-analyses on pain (117 studies, n = 63,533) and pain severity (52 studies, n = 32,261). Pain prevalence rates were 39.3% after curative treatment; 55.0% during anticancer treatment; and 66.4% in advanced, metastatic, or terminal disease. Moderate to severe pain (numerical rating scale score ≥5) was reported by 38.0% of all patients.

CONCLUSION

Despite increased attention on assessment and management, pain continues to be a prevalent symptom in patients with cancer. In the upcoming decade, we need to overcome barriers toward effective pain treatment and develop and implement interventions to optimally manage pain in patients with cancer.

The unmet supportive care needs-what advanced lung cancer patients' caregivers need and related factors

PURPOSE

To identify the unmet supportive care needs and related factors in caregivers of patients with advanced lung cancer.

METHODS

A cross-sectional study of 166 lung cancer patient-caregivers dyads was recruited at a medical center. The supportive care needs, fatigue, and sleep disturbance of caregivers were collected. Patients were assessed for symptom severity, anxiety, and depression. Logistic regression was used to reveal the related factors of unmet supportive care needs.

RESULTS

Of the 166 dyads surveyed, the top unmet needs were information needs, health care professional/health care service needs, and daily living needs. Patients' anxiety was positively correlated to overall caregiving needs, health care professional/health care service needs, interpersonal communication needs, and psychological/emotional needs of caregivers. The information needs and health care professional/health care service needs were related to the caregivers' fatigue. The sleep disturbance of caregivers was associated with their overall caregiving needs, daily living needs, and psychological/emotional needs.

CONCLUSIONS

Future interventions to meet the needs of caregivers should include specific needs assessment and continuing education in caregiving.

Palliative Care in Lung Cancer

Lung cancer is the most common cancer worldwide and is the leading cause of cancer death for both men and women in the USA. Symptom burden in patients with advanced lung cancer is very high and has a negative impact on their quality of life (QOL). Palliative care with its focus on the management of symptoms and addressing physical, psychosocial, spiritual, and existential suffering, as well as medically appropriate goal setting and open communication with patients and families, significantly adds to the quality of care received by advanced lung cancer patients. The Provisional Clinical Opinion (PCO) of American Society of Clinical Oncology (ASCO) as well as the National Cancer Care Network's (NCCN) clinical practice guidelines recommends early integration of palliative care into routine cancer care. In this chapter, we will provide an overview of palliative care in lung cancer and will examine the evidence and recommendations with regard to a comprehensive and interdisciplinary approach to symptom management, as well as discussions of goals of care, advance care planning, and care preferences.
