Pain, fatigue, disturbed sleep and distress comprised a symptom cluster that related to quality of life and functional status of lung cancer surgery patients

The change of symptom clusters in gastric cancer patients during the perioperative period: a longitudinal study

AIM AND OBJECTIVES

The purpose of this study was to describe the number, type and trajectory of symptom clusters during the perioperative period in patients with gastric cancer at four different time points. The study also aimed to identify the changes and consistency of these symptom clusters over time.

DESIGN

This was a longitudinal study.

METHODS

This study was conducted in a tertiary cancer hospital with 205 patients with gastric cancer. The M.D. Anderson Symptom Inventory Gastrointestinal Cancer Module was used to assess the incidence and severity of symptom clusters. Exploratory factor analysis was used to extract symptom clusters.

RESULTS

The study identified four symptom clusters in patients with gastric cancer during the perioperative period: gastrointestinal symptom cluster, physical symptom cluster, psychological symptom cluster, and sleep disturbance symptom cluster. These clusters were observed across two to four time points.

CONCLUSION

The findings of this study provide scientific evidence for medical staff and researchers to better understand the symptoms of patients with gastrointestinal cancer during the perioperative period. These findings can help develop individualized interventions for managing symptoms.

RELEVANCE TO CLINICAL PRACTICE

Gastric cancer patients suffered from various symptom clusters, which lasted from one day before surgery to one month after surgery. They should be given careful consideration by clinical staff.

Cancer symptom cluster research in pediatric oncology: a work in progress

In the 21st century, advances in basic research have provided new insights in the field of pediatric oncology. Pediatric patients tend to experience higher levels of distressing symptoms, which together form a symptom cluster. In clinical practice, these symptom clusters are reported daily by children and adolescents with cancer. Translational research has emerged as the translation of new knowledge from basic science into clinical practice. Understanding how neuroimmunoendocrine pathways regulate cancer development and the aspects underlying the specific therapies, such as chemotherapy and immunotherapy, is an important frontier for future research in pediatric oncology. The goal of translational research is to show how different variables in tumor and patient characteristics explain the differential effects of interventions, as translational research provides new insights into the management of cancer symptoms in children and adolescents with cancer. Together, this approach could lead to improvements in pediatric oncology care worldwide.

Role of social support in the relationship between resilience and sleep quality among cancer patients

Introduction

The present study aimed to investigate the effect of resilience on sleep quality and explore the role of social support between resilience and sleep quality in cancer patients.

Methods

A multicenter and cross-sectional study was conducted in China from May to November 2021. A total of 202 cancer patients were recruited to complete the questionnaires composed of demographic information, Pittsburg Sleep Quality Index (PSQI), Resilience Scale-14 (RS-14), and Multidimensions Scale of Perceived Social Support (MSPSS). The associations between resilience, social support, and sleep quality were explored through hierarchical regression analysis.

Results

The prevalence of poor sleep quality was 50% among cancer patients. Resilience, social support, and the interaction between resilience and social support were all found to be significantly associated with sleep quality. Results of simple slope analysis indicated that the association between resilience and sleep quality were gradually decreased with the increasing social support levels (1 SD below the mean, B=-0.225, β=-0.551, P<0.001), mean social support (B=-0.147, β=-0.353, P<0.001) and high social support (1 SD above the mean, B=-0.065, β=-0.156, P<0.001). Additionally, social support mediated the effect of resilience on sleep quality among cancer patients.

Discussion

Poor sleep quality has been common in cancer patients. Social support could mediate and alleviate the relationship between resilience and sleep quality among cancer patients. Besides providing sufficient social support, interventions based on resilience should be applied to address sleep problems in cancer patients.

Comparison of early patient-reported outcomes between uniportal thoracoscopic segmentectomy and wedge resection for peripheral small-sized non-small-cell lung cancer

BACKGROUND

Analysis of patient-reported outcomes (PROs) offers valuable insights into distinguishing the effects of closely related medical procedures from the patient's perspective. In this study we compared symptom burden in patients undergoing uniportal thoracoscopic segmentectomy and wedge resection for peripheral small-sized non-small cell lung cancer (NSCLC).

METHODS

This study included patients with peripheral NSCLC from an ongoing longitudinal prospective cohort study (CN-PRO-Lung 3) who underwent segmentectomy or wedge resection with tumor diameter ≤ 2 cm and consolidation tumor ratio (CTR) ≤ 0.5. PROs data were collected using the Perioperative Symptom Assessment for Lung Surgery questionnaire pre-operatively, daily post-surgery up to the fourth hospitalization day, and weekly post-discharge up to the fourth week. Propensity score matching and a generalized estimation equation model were employed to compare symptom severity. In addition, short-term clinical outcomes were compared.

RESULTS

In total, data of 286 patients (82.4%) undergoing segmentectomy and 61 patients (17.6%) undergoing wedge resection were extracted from the cohort. No statistically significant differences were found in the proportion of moderate-to-severe symptoms and mean scores for pain, cough, shortness of breath, disturbed sleep, fatigue, drowsiness, and distress during the 4-day postoperative hospitalization or the 4-week post-discharge period before or after matching (all p > 0.05). Compared with segmentectomy, wedge resection showed better short-term clinical outcomes, including shorter operative time (p = 0.001), less intraoperative bleeding (p = 0.046), and lower total hospital costs (p = 0.002).

CONCLUSIONS

The study findings indicate that uniportal thoracoscopic segmentectomy and wedge resection exert similar early postoperative symptom burden in patients with peripheral NSCLC (tumor diameter ≤ 2 cm and CTR ≤ 0.5).

Longitudinal patterns of patient-reported sleep disturbances after surgery for lung cancer

PURPOSE

The purpose of this study was to identify longitudinal heterogeneous trajectories of sleep status, adjusted for the effect of pain over time, among patients who had surgery for lung cancer and to quantify how disturbed sleep in the hospital affects functional recovery after discharge.

METHODS

We included patients from a surgical cohort (CN-PRO-Lung 1). All patients reported symptoms using the MD Anderson Symptom Inventory-Lung Cancer (MDASI-LC) daily during postoperative hospitalization. Group-based dual trajectory modeling was used to investigate trajectories of disturbed sleep and pain during the first 7 days of postoperative hospitalization. Cox regression was used to compare the recovery of walking ability between the different sleep trajectories.

RESULTS

Among 421 patients, disturbed sleep trajectories comprised low (31%), moderate (52%), and high (17%) groups. The surgical approach and number of chest tubes were associated with pain, and the number of chest tubes was also associated with sleep disturbances (OR = 1.99; 95% CI: 1.08-3.67). Recovery of walking ability after discharge was significantly slower in the high (median days = 16; 95% CI: 5-NA) and moderate disturbed sleep trajectory groups (median days = 5; 95%CI: 4-6) than in the low group (median days = 3; 95% CI: 3-4).

CONCLUSION

Changes in disturbed sleep among patients with lung cancer followed three distinct trajectories over the first 7 days of hospitalization after surgery. Dual trajectory analyses highlighted the high concordance between specific trajectories of disturbed sleep and pain. Patients at high sleep disturbance and high levels of pain may benefit from appropriate interventions for both symptoms in combination with the patient's surgical approach and the number of chest tubes.

Application of the patient-reported outcome-based postoperative symptom management model in lung cancer: a multicenter randomized controlled trial protocol

INTRODUCTION

Lung cancer is the most common cancer in China, with the highest mortality rate. Surgery is the primary treatment for early lung cancer. However, patients with lung cancer have a heavy burden of symptoms within 3 months after surgery, which seriously affects their quality of life (QOL). The symptom management model based on the patient-reported outcome (PRO) is considered the best caregiving model. The clinical evidence about the symptom management of lung cancer within 3 months after the operation is very limited. Herein, we propose a randomized controlled trial to evaluate the PRO score-based monitoring and alert system for follow-up on psychological and physiological symptoms of lung cancer patients within 3 months after surgery and further investigate the effect of intervention measures based on this PRO score-based system.

METHODS AND ANALYSIS

This multicenter, open-label, randomized, parallel superiority trial will be conducted at four hospitals in China. A total of 440 lung cancer patients will be recruited in this study, who will be randomly assigned to the intervention group or the control group in a ratio of 1:1. Any of the target symptoms reaches the preset threshold (score ≥ 4), the patients will accept the symptom management advices based on the PRO. The patients in the control group will follow the current standard procedure of symptom management. The symptom management system is an electronic management system based on WeChat mini programs. All patients will be evaluated for symptoms through the lung cancer module of the MDASI lung cancer-specific scale on the day before surgery, days 1, 3, 5, and 7 after surgery, and once a week during the 12-week post-discharge period. Simultaneously, the EORTC QLQ-C30 scale will be used to evaluate patients' quality of life at baseline and the fourth and twelfth week after the surgery. The mean number of symptom threshold events of the intervention and the control groups were compared by t-test, and the changes of PRO were compared by a mixed effect model. The primary endpoint has been set as the 12-week post-discharge period.

DISCUSSION

This study will test the feasibility of the symptom management system based on the mobile social media applet in postoperative caregiving and the efficacy of psychiatrist-assisted treatment and provide evidence in managing the symptoms of patients in the medium and long term.

A latent profile analysis of resilience and their relation to differences in sleep quality in patients with lung cancer

PURPOSE

Sleep problems are a significant issue in patients with lung cancer, and resilience is a closely related factor. However, few studies have identified subgroups of resilience and their relationship with sleep quality. This study aimed to investigate whether there are different profiles of resilience in patients with lung cancer, to determine the sociodemographic characteristics of each subgroup, and to determine the relationship between resilience and sleep quality in different subgroups.

METHODS

A total of 303 patients with lung cancer from four tertiary hospitals in China completed the General Sociodemographic sheet, the Connor-Davidson Resilience Scale, and the Pittsburgh Sleep Quality Index. Latent profile analysis was applied to explore the latent profiles of resilience. Multivariate logistic regression was used to analyze the sociodemographic variables in each profile, and ANOVA was used to explore the relationships between resilience profiles and sleep quality.

RESULTS

The following three latent profiles were identified: the "high-resilience group" (30.2%), the "moderate-resilience group" (46.0%), and the "low-resilience group" (23.8%). Gender, place of residence, and average monthly household income significantly influenced the distribution of resilience in patients with lung cancer.

CONCLUSION

The resilience patterns of patients with lung cancer varied. It is suggested that health care providers screen out various types of patients with multiple levels of resilience and pay more attention to female, rural, and poor patients. Additionally, individual differences in resilience may provide an actionable means for addressing sleep problems.

Exploring the interconnectedness between health-related quality of life factors among long-term adolescent and young adult cancer survivors (AYAs): a network analysis

PURPOSE

Adolescent and young adult cancer survivors (AYAs) are at increased risk of long-term and late effects, and experience unmet needs, impacting their health-related quality of life (HRQoL). In order to provide and optimize supportive care and targeted interventions for this unique population, it is important to study HRQoL factors' interconnectedness on a population level. Therefore, this network analysis was performed with the aim to explore the interconnectedness between HRQoL factors, in the analysis described as nodes, among long-term AYAs.

METHODS

This population-based cohort study used cross-sectional survey data of long-term AYAs, who were identified by the Netherlands Cancer Registry (NCR). Participants completed a one-time survey (SURVAYA study), including the EORTC survivorship questionnaire (QLQ-SURV111) to assess their long-term HRQoL outcomes and sociodemographic characteristics. The NCR provided the clinical data. Descriptive statistics and a network analysis, including network clustering, were performed.

RESULTS

In total, 3596 AYAs (on average 12.4 years post diagnosis) were included in our network analysis. The network was proven stable and reliable and, in total, four clusters were identified, including a worriment, daily functioning, psychological, and sexual cluster. Negative health outlook, part of the worriment cluster, was the node with the highest strength and its partial correlation with health distress was significantly different from all other partial correlations.

CONCLUSION

This study shows the results of a stable and reliable network analysis based on HRQoL data of long-term AYAs, and identified nodes, correlations, and clusters that could be intervened on to improve the HRQoL outcomes of AYAs.

Changes in the symptom clusters of elderly patients with lung cancer over the course of postoperative rehabilitation and their correlation with frailty and quality of life: A longitudinal study

OBJECTIVE

To explore changes in the symptom clusters of perioperatively elderly patients with lung cancer at different time points (i.e., the day of admission [T0]), 2-4 days after surgery [T1], 1 month after discharge [T2] and 3 months after discharge [T3]) and to analyze correlations between cluster severity, frailty and quality of life (QOL).

METHODS

A longitudinal study was conducted from August 2020 to June 2021 among elderly lung cancer patients undergoing surgery at hospitals in Jiangsu Province. Data were collected using the Chinese Tilburg Frailty Indicator, the MD Anderson Symptom Inventory and the Quality of Life-Core scale.

RESULTS

According to exploratory factor analysis, a total of 5 symptom clusters were found and three of them (the global mental function symptom cluster, the special mental function symptom cluster and the respiratory function symptom cluster) were persistent. The incidence of the top four symptoms varied at different time points. The severity of symptom clusters at different time points was positively correlated with frailty and negatively correlated with QOL.

CONCLUSIONS

The findings may serve as a reference for medical staff to implement symptom management in elderly lung cancer patients after surgery. Frailty may be an important variable affecting the severity of symptom clusters and the QOL of patients.

Patient-Reported Outcome-Based Prediction for Postdischarge Complications after Lung Surgery

BACKGROUND

Patients undergoing lung tumor surgery may experience various complications after discharge from the hospital. Using patient-reported outcomes (PROs), this study attempted to identify relevant indicators of postdischarge complications after lung tumor surgery and develop a predictive nomogram model to evaluate the risk for individual patients.

METHODS

Patients who underwent lung tumor surgery between December 2021 and June 2022 were included in this study. PROs were assessed using the Perioperative Symptom Assessment for Lung Surgery scale and were assessed preoperatively at baseline, on postoperative day 1 (POD1) 1 to POD4, and then weekly until the fourth week. A random forest machine learning prediction model was built to rank the importance of each PRO score of patients on POD1 to POD4. We then selected the top 10 variables in terms of importance for the multivariable logistic regression analysis. Finally, a nomogram was developed.

RESULTS

PROs, including coughing (POD3 and POD4), daily activity (POD1), and pain (POD1 and POD2), were associated with postdischarge complications in patients undergoing lung tumor surgery. The predictive model showed good performance in estimating the risk of postdischarge complications, with an area under the curve of 0.833 (95% confidence interval: 0.753-0.912), while maintaining good calibration and clinical value.

CONCLUSION

We found that PRO scores on POD1 to POD4 were associated with postdischarge complications after lung tumor surgery, and we developed a helpful nomogram model to predict the risk of postdischarge complications.

Post-Operative Poor Sleep Quality and Its Associated Factors Among Non-Small Cell Lung Cancer Patients: A Cross-Sectional Study

Objective

The study aimed to determine the post-operative prevalence and factors associated to poor sleep quality in non-small cell lung cancer (NSCLC) patients in China.

Methods

NSCLC patients (n=307) who underwent thoracoscopic surgery at the Department of Thoracic Surgery of Shanghai Pulmonary Hospital were enrolled in this study. The Pittsburgh Sleep Quality Index (PSQI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Prince Henry Hospital Pain Score and the Six-Minute Walk Test (6MWT), and Forced Expiratory Volume in one second (FEV-1) were used to assess the factors that could lead to poor sleep quality. All assessments were carried out between April 1 and May 30, 2023. Descriptive analyses and stepwise factor regression were employed to determine the impact of various factors on sleep quality. The factors predictive of poor sleep quality were used to develop a predictive nomogram. The Hosmer-Lemeshow test was used to assess the predictive value of the nomogram.

Results

The median PQSI score was 8 (interquartile range (IQR) 5-12), and 74.6% of patients had poor sleep quality. The median anxiety and depression scores were 6 (IQR 3-9) and 4 (IQR 2-7), respectively. The PSQI latency dimension had the highest score, while the use of sleep medications dimension had the lowest score. The multivariate analysis revealed that patients who were female (OR, 2.38; 95% CI, 1.40-4.05; P <0.01), had post-secondary education (OR, 0.42; 95% CI, 0.19-0.92; P =0.03), tertiary education (OR, 0.38; 95% CI, 0.17-0.84; P =0.02), comorbidities (OR, 2.57; 95% CI, 1.51-4.39; P <0.01), a pain score 1 (OR, 4.22; 95% CI, 2.37-7.50; P <0.01), and cough (OR, 2.97; 95% CI, 1.63-5.40; P <.001) were more like to experience poor sleep quality. The positive predictive value of the nomogram was 79.80% (p=0.390).

Conclusion

Sociodemographic variables, comorbidities, and pain could be used to predict the post-operative sleep quality in NSCLC patients.

Psychological outcomes of the systematic interventions based on the stress-induced situation, affective, bodily, and cognitive reactions framework for patients with lung cancer: A randomized clinical trial

BACKGROUND

Psychological distress is a multi-factorial unpleasant experience of a psychological, social, spiritual, and/or physical nature that may interfere with one's ability to cope effectively with cancer, physical symptoms and treatment. Psychological distress is common and affects the prognosis of cancer patients. Lung cancer accounted for 11.4 % of all new cancer cases and 18 % of all cancer mortality for 36 cancers in 185 countries. The prevalence of distress among Chinese lung cancer patients ranged from 10.1 % to 61.29 %. However, the existing intervention studies on the psychological distress in lung cancer patients are limited and intervention results may be different.

OBJECTIVES

To explore the psychological outcomes of a nurse-led systematic intervention program based on the stress-induced situation, affective, bodily, and cognitive reactions framework for patients with lung cancer undergoing operation at anxiety and depression.

DESIGN

A randomized clinical trial.

SETTING

Thoracic surgery ward in a tertiary hospital in China.

PARTICIPANTS

Lung cancer patients undergoing surgery.

METHODS

This is a 12-month longitudinal randomized controlled study in a tertiary hospital in China. A total of 240 lung cancer patients were randomly divided into either the control group or the intervention group. The nurse-led systematic intervention contents include psychological education, intervention measures based on the stress-induced situation, affective, bodily, and cognitive reactions framework, issuance of daily lifestyle cards, and regular follow-ups. The Hospital Anxiety and Depression Scale, Functional Assessment of Chronic Illness Therapy-Fatigue Scale, and Satisfaction with Life Scale were used for the baseline assessment within 48 h upon admission. The same assessment was performed respectively at 1, 3, 6 and 12 months after the intervention started. The effects of the systematic interventions on depression, anxiety, fatigue, and life satisfaction were tested by a linear mixed effects model.

RESULTS

Overall time-by-group interaction effects were significantly different with regard to anxiety, depression, and fatigue after controlling for the covariates, while a significant time-by-group interaction effect was not found for life satisfaction. Changes for anxiety and depression scores at 6 and 12 months after initiation of the intervention were significantly greater in the intervention group compared with those in the control group (t = 3.046, p = 0.002, t = 3.190, p = 0.001; t = 3.735, p = 0.000, t = 2.979, p = 0.002), whereas scores for fatigue were significantly higher in the intervention group at 6 and 12 months (t = -3.096, p = 0.002, t = -2.784, p = 0.005).

CONCLUSION

The systematic intervention program based on the stress-induced situation, affective, bodily, and cognitive reactions framework may effectively relieve anxiety, depression, and fatigue in lung cancer patients undergoing surgery.

Quality of life considerations and management in patients with myelodysplastic syndrome

INTRODUCTION

This study aimed to identify the factors affecting the quality of life (QOL) and functional status of patients with MDS.

AREAS COVERED

We reviewed the literature published in PUBMED over the past 30 years and searched for keywords such as 'quality of life' and 'myelodysplastic syndromes'. By observing the influence of their symptoms, the possibility of improving patients' QOL was considered by improving these related factors. Concurrently, the effects of related clinical treatments based on the unique disease characteristics of MDS on the patients' QOL were examined, and lifestyle factors were considered in clinical practice, providing an important path to improve the QOL and functional status of patients with MDS.

EXPERT OPINION

This review summarized several areas that can improve the quality of survival of MDS patients and discusses them in depth. Although the clinical benefits may be minimal, we still hope to improve patients' daily life outcomes and enhance their quality of life at minimal cost. Also, we hope more researchers will focus on this area in the future to find more factors that may exist to supplement the limitations of these understanding and thinking, and to provide assistance in clinical work.

Sleep disturbance and decrements in morning energy contribute to a higher symptom burden in oncology patients

OBJECTIVE/BACKGROUND

An emerging area of research is the relationship between sleep disturbance and decrements in energy. Given the paucity of research on the co-occurrence of these two symptoms, study purposes were to identify subgroups of oncology patients with distinct joint sleep disturbance AND morning energy profiles and evaluate for differences among the subgroups in demographic, clinical, and sleep disturbance characteristics, as well as the severity of other common symptoms and QOL outcomes.

PATIENTS/METHODS

Patients (n = 1336) completed measures of sleep disturbance and energy 6 times over two cycles of chemotherapy. All of the other measures were completed at enrollment. Latent profile analysis was used to identify the distinct joint sleep disturbance and morning energy profiles.

RESULTS

Three distinct profiles were identified (i.e., Low Sleep Disturbance and High Morning Energy (Normal, 20.6%), Moderate Sleep Disturbance and Low Morning Energy (Moderately Severe, 52.1%), Very High Sleep Disturbance and Very Low Morning Energy (Very Severe, 27.3%). Compared to Normal class, other two classes were more likely to be female, less likely to be employed, and had higher comorbidity burden and poorer functional status. Symptom scores and QOL outcomes exhibited a dose response effect (i.e., as the profile worsened, symptom scores increased and QOL scores decreased).

CONCLUSIONS

Given the associations between sleep disturbance and decrements in energy and a higher symptom burden, poorer QOL outcomes, and increased mortality, assessment of these two symptoms needs to be a high priority for clinicians and appropriate interventions initiated.

Participatory action research intervention for improving sleep in inpatients with cancer

AIM

To design and implement a plan to improve oncohaematological patients' sleep.

BACKGROUND

The hospital environment can compromise inpatients' sleep, negatively impacting on health outcomes and patient satisfaction.

DESIGN AND METHOD

The improvement plan was designed in collaboration with 18 professionals, 3 patients and 3 accompanying relatives. The study designed followed the SQUIRE 2.0 guidelines. Outcome variables were self-reported patient satisfaction regarding sleep, measured using a 30-item, ad hoc questionnaire and a 10-point visual analogue scale, completed by 318 oncohaematological inpatients (pre-intervention n = 120, post-intervention, n = 198) in a comprehensive cancer centre in Spain from 2017 to 2019.

RESULTS

Overall, 61.5% (n = 190) of the inpatients reported sleep alterations, and 92.6% reported interruptions in their nightly sleep. Half slept less than 6 h/night, but 58.0% said they felt rested upon waking, despite the interruptions. These outcomes were similar before and after the intervention. The improvement plan identified four domains for work (professionals, care procedures, instruments/environment and patients/relatives), 10 areas for improvement and 35 actions for implementation. However, overall sleep worsened significantly, from 6.73 to 6.06 on the 10-point scale. The intervention significantly improved variables related to professionals' behaviour, including noise during the shift change, conversations at the control desk and the use of corridor lights. Sleep disturbances were mainly caused by pain/discomfort and infuser alarms, and collectively they decreased significantly after the intervention (p = .008). However, overall sleep worsened significantly, from 6.73 to 6.06 on the 10-point scale.

CONCLUSIONS

Pain, clinical devices and noise made by professionals are the main causes of sleep disturbances. Involving professionals in decision-making to improve patients' sleep have a positive impact on noise levels.

RELEVANCE TO CLINICAL PRACTICE

This study proposes new strategies for improving sleep by increasing staff awareness and changing attitudes towards patients' sleep. Nurses should be involved in addressing sleep disturbances during hospitalization.

Cancer-related Fatigue in Lung Cancer: A Research Agenda: An Official American Thoracic Society Research Statement

Background: Fatigue is the most common symptom among cancer survivors. Cancer-related fatigue (CRF) may occur at any point in the cancer care continuum. Multiple factors contribute to CRF development and severity, including cancer type, treatments, presence of other symptoms, comorbidities, and medication side effects. Clinically, increasing physical activity, enhancing sleep quality, and recognizing sleep disorders are integral to managing CRF. Unfortunately, CRF is infrequently recognized, evaluated, or treated in lung cancer survivors despite more frequent and severe symptoms than in other cancers. Therefore, increased awareness and understanding of CRF are needed to improve health-related quality of life in lung cancer survivors. Objectives: 1) To identify and prioritize knowledge and research gaps and 2) to develop and prioritize research questions to evaluate mechanistic, diagnostic, and therapeutic approaches to CRF among lung cancer survivors. Methods: We convened a multidisciplinary panel to review the available literature on CRF, focusing on the impacts of physical activity, rehabilitation, and sleep disturbances in lung cancer. We used a three-round modified Delphi process to prioritize research questions. Results: This statement identifies knowledge gaps in the 1) detection and diagnostic evaluation of CRF in lung cancer survivors; 2) timing, goals, and implementation of physical activity and rehabilitation; and 3) evaluation and treatment of sleep disturbances and disorders to reduce CRF. Finally, we present the panel's initial 32 research questions and seven final prioritized questions. Conclusions: This statement offers a prioritized research agenda to 1) advance clinical and research efforts and 2) increase awareness of CRF in lung cancer survivors.

Neurocognitive impairment, neurobehavioral symptoms, fatigue, sleep disturbance, and depressive symptoms in patients with newly diagnosed glioblastoma

Background

In addition to poor survival rates, individuals with glioblastoma (GBM) are at risk of neurocognitive impairment due to multiple factors. This study aimed to characterize neurocognitive impairment, neurobehavioral symptoms, fatigue, sleep disturbance, and depressive symptoms in newly diagnosed GBM patients; and to examine whether neurobehavioral symptoms, fatigue, sleep, and depressive symptoms influence neurocognitive performance.

Methods

This study was part of a prospective, inception cohort, single-arm exercise intervention in which GBM patients underwent a neuropsychological assessment shortly after diagnosis (median 4 weeks; ie, baseline) and 3, 6, 12, and 18 months later, or until tumor progression. Here, we present baseline data. Forty-five GBM patients (mean age = 55 years) completed objective neurocognitive tests, and self-report measures of neurobehavioral symptoms, fatigue, sleep disturbance, and depressive symptoms.

Results

Compared to normative samples, GBM patients scored significantly lower on all neurocognitive tests, with 34 (76%) patients exhibiting neurocognitive impairment. Specifically, 53% exhibited impairment in memory retention, 51% in executive function, 42% in immediate recall, 41% in verbal fluency, and 24% in attention. There were high rates of clinically elevated sleep disturbance (70%), fatigue (57%), depressive symptoms (16%), and neurobehavioral symptoms (27%). A multivariate regression analysis revealed that depressive symptoms are significantly associated with neurocognitive impairment.

Conclusions

GBM patients are vulnerable to adverse outcomes including neurocognitive impairment, neurobehavioral symptoms, fatigue, sleep disturbance, and depressive symptoms shortly after diagnosis, prior to completing chemoradiation. Those with increased depressive symptoms are more likely to demonstrate neurocognitive impairment, highlighting the need for early identification and treatment of depression in this population.

A nationally representative study of aerobic activity and strength training in older cancer survivors and their psychological distress and sleep difficulties

OBJECTIVE

To examine the prevalence of different levels of aerobic activity and strength training in older cancer survivors and their associations with psychological distress and sleep difficulties.

METHODS

We used cross-sectional data from the 2016-2018 National Health Interview Survey on 3,425 survivors aged ≥ 65 years. Individuals were classified into active, insufficiently active, and inactive categories, and by whether they reported strength training at least twice per week. The outcome variables were self-reported psychological distress, trouble falling asleep, trouble staying asleep, and trouble waking up feeling rested. Multivariate logistic models were used to calculate the odds ratios (ORs) and the 95% confidence intervals (CIs).

RESULTS

Only 35.2% of older survivors reached the recommended aerobic activity guidelines, and 12% had strength training at least twice per week. A total of 626 (18.3%) reported at least moderate psychological distress, and 1,137 (33.2%) had trouble staying asleep. For survivors who reported strength training less than two times per week, being insufficiently active or inactive was associated with worse psychological distress (OR 1.52, 95% CI 1.17-1.97; OR 1.30, 95% CI 1.02-1.64) and more sleep difficulties (OR ranging from 1.33 to 2.07). Among active survivors, strength training two or more times per week was associated with more trouble staying asleep (OR 1.67, 95% CI 1.06-2.58).

CONCLUSIONS

Most older cancer survivors did not meet the recommended physical activity guidelines and suffered from psychological distress and sleep difficulties. Additional research may be needed to examine the effects of frequent muscle strength training on sleep quality.

Profiling symptom burden and its influencing factors at discharge for patients undergoing lung cancer surgery: a cross-sectional analysis

Background

Following lung cancer surgery, patients often experience severe symptoms which are not properly assessed at discharge. The aim of this study was to identify the clinical presentation at discharge and the influencing factors of postoperative symptoms in patients who have undergone lung cancer surgery.

Methods

This cross-sectional study analysed data from patients who participated in a prospective cohort study that enrolled patients who underwent lung cancer surgery at six tertiary hospitals in the People’s Republic of China, from November 2017 to January 2020. Patient symptoms at discharge were measured using the MD Anderson Symptom Inventory Lung Cancer module. The five core symptoms were defined according to ratings of moderate to severe symptoms (≥ 4 on a 0–10 scale). A multivariate linear regression model was used to identify the influencing factors of each symptom at discharge.

Results

Among the 366 participants, 51.9% were male and the mean (SD) age was 55.81 (10.43) years. At discharge, the core symptoms were cough (36.4%), pain (28.2%), disturbed sleep (26.3%), shortness of breath (25.8%), and fatigue (24.3%), and more than half of the participants (54.6%) had one to five of the core symptoms, with moderate to severe severity. A low annual income and the use of two chest tubes were significantly associated (P = 0.030 and 0.014, respectively) with higher mean scores of the core symptoms.

Conclusion

Though clinically eligible for discharge, more than half of the participants had severe symptoms at discharge after lung cancer surgery. Special attention should be given to patients who have two chest tubes after surgery and those who have a low annual income.

Postoperative Symptom Burden in Patients Undergoing Lung Cancer Surgery

CONTEXT

Previous studies on quality of life (QOL) after lung cancer surgery have identified a long duration of symptoms postoperatively. We first performed a systematic review of QOL in patients undergoing surgery for lung cancer. A subgroup analysis was conducted focusing on symptom burden and its relationship with QOL.

OBJECTIVE

To perform a qualitative review of articles addressing symptom burden in patients undergoing surgical resection for lung cancer.

METHODS

The parent systematic review utilized search terms for symptoms, functional status, and well-being as well as instruments commonly used to evaluate global QOL and symptom experiences after lung cancer surgery. The articles examining symptom burden (n = 54) were analyzed through thematic analysis of their findings and graded according to the Oxford Centre for Evidence-based Medicine rating scale.

RESULTS

The publication rate of studies assessing symptom burden in patients undergoing surgery for lung cancer have increased over time. The level of evidence quality was 2 or 3 for 14 articles (cohort study or case control) and level of 4 in the remaining 40 articles (case series). The most common QOL instruments used were the Short Form 36 and 12, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire, and the Hospital Anxiety and Depression Score. Thematic analysis revealed several key findings: 1) lung cancer surgery patients have a high symptom burden both before and after surgery; 2) pain, dyspnea, cough, fatigue, depression, and anxiety are the most commonly studied symptoms; 3) the presence of symptoms prior to surgery is an important risk factor for higher acuity of symptoms and persistence after surgery; and 4) symptom burden is a predictor of postoperative QOL.

CONCLUSION

Lung cancer patients undergoing surgery carry a high symptom burden which impacts their QOL. Measurement approaches use myriad and heterogenous instruments. More research is needed to standardize symptom burden measurement and management, with the goal to improve patient experience and overall outcomes.

Bad company: Loneliness longitudinally predicts the symptom cluster of pain, fatigue, and depression in older adults

BACKGROUND

Pain, fatigue, and depression frequently co-occur as a symptom cluster. While commonly occurring in those with cancer and autoimmune disease, the cluster is also found in the absence of systemic illness or inflammation. Loneliness is a common psychosocial stressor associated with the cluster cross-sectionally. We investigated whether loneliness predicted the development of pain, fatigue, depression, and the symptom cluster over time.

METHODS

Data from the Health and Retirement Study were used. We included self-respondents ≥50 year-old who had at least two measurements of loneliness and the symptom cluster from 2006-2016 (n = 5974). Time-varying loneliness was used to predict pain, fatigue, depression, and the symptom cluster in the subsequent wave(s) using generalized estimating equations (GEE) and adjusting for sociodemographic covariates, living arrangement, and the presence of the symptom(s) at baseline.

RESULTS

Loneliness increased the odds of subsequently reporting pain (aOR 1.22, 95% CI 1.08, 1.37), fatigue (aOR 1.47, 95% CI 1.32, 1.65), depression (aOR 2.33, 95% CI 2.02, 2.68), as well as the symptom cluster (aOR 2.15, 95% CI 1.74, 2.67). The median time between the baseline and final follow-up measurement was 7.6 years (IQR 4.1, 8.2).

CONCLUSIONS

Loneliness strongly predicts the development of pain, fatigue, and depression as well as the cluster of all three symptoms several years later in a large, nonclinical sample of older American adults. Future studies should examine the multiple pathways through which loneliness may produce this cluster, as well as examine whether other psychosocial stressors also increase risk. It is possible that interventions which address loneliness in older adults may prevent or mitigate the cluster of pain, fatigue, and depression.

Nutrition Support & Intervention Preferences of Cancer Survivors

INTRODUCTION

Ascertaining cancer survivors' specific needs and preferences regarding nutrition information delivery is important in developing and designing future health interventions in oncology. This study aimed to explore the nutrition information needs of cancer survivors and their preferences regarding intervention delivery.

METHODS

The present study is a mixed-methods study comprising a cross-sectional survey and focus groups. Participants were eligible for inclusion if they were 18+years, living in Ireland with a cancer diagnosis and had completed treatment at least six months previous. Cancer support centres promoted the online survey on social media. Focus groups were conducted with twenty individuals.

RESULTS

The cohort (n=56) were predominantly female (n=50, 89.3%), breast cancer survivors (n=42, 75%). Seven (12.5%) had received nutrition advice from a dietitian. Most are interested in receiving nutrition advice (n=52, 92.9%), with variability in delivery mode. There was interest in improving sleep quality (n=35, 62.5%), making positive lifestyle changes (n=28, 50%) and accessing cancer-specific physical activity classes (n=27, 48.2%). The best time to deliver information was throughout the cancer journey (n=31, 55.4%). Time and motivation (n=15, 26.8%) were the main barriers. Facilitators were keeping healthy (n=42, 75%), and weight maintenance (n=31, 55.4%). Four themes emerged from thematic analysis; lack of nutrition guidance, an abundance of misinformation, one size does not fit all and dietitians as the preferred source of advice.

CONCLUSION

There is a desire for evidence-based nutrition advice and for dietitians to be integrated into cancer clinics and cancer survivorship care. This research guides future interventional work on the efficacy of nutrition interventions to improve cancer survivorship outcomes. This article is protected by copyright. All rights reserved.

Factors Related to the Caregiving Burden on Families of Korean Patients With Lung Cancer

The purposes of this study were to describe caregiver burden on families of patients with lung cancer and to examine its associated factors, including patient symptoms and symptom clusters. In this cross-sectional study, 120 patient-caregiver dyads were recruited from an outpatient clinic in a tertiary care hospital. Patient symptoms and caregiver burden were measured with structured questionnaire. Descriptive and inferential statistics were used to analyze data. Three patient symptom clusters were identified. Hierarchical regression showed that a patient's smoking history; caregiver age, education, health status, depression, social support, monthly family income, relationship with patient, and time spent on nursing each day; and presence of another caregiver explained 41.4% of the total variance in caregiver burden. When patient symptom clusters were added to regression model, change in total variance in caregiver burden was significant. To reduce their burden, caregivers should be taught how cancer progresses and its major symptoms after chemotherapy.

Synergistic Interactions Among Fatigue, Sleep Disturbance, and Depression in Women With Breast Cancer: A Cross-Sectional Study

OBJECTIVES

To assess the symptom cluster of fatigue, sleep disturbance, and depression among female patients with breast cancer receiving chemotherapy, and to evaluate its impact on quality of life (QOL) and symptom severity.

SAMPLE & SETTING

372 patients receiving adjuvant chemotherapy recruited from two tertiary hospitals in China.

METHODS & VARIABLES

Symptom severity and QOL were evaluated using the Brief Fatigue Inventory, Pittsburgh Sleep Quality Index, Patient Health Questionnaire-9, and Functional Assessment of Cancer Therapy-Breast on the eighth day after receiving chemotherapy.

RESULTS

All symptoms positively correlated with each other. Although the symptom cluster was significantly associated with decreased QOL, individualized symptom severity worsened as the number of symptoms increased.

IMPLICATIONS FOR NURSING

The prevalence of and interactions among fatigue, sleep disturbance, and depression negatively affect symptom severity and patients' QOL. Conducting early assessment followed by effective cluster-based interventions is needed to manage this symptom cluster.

A cross-sectional study of obstructive sleep apnea in patients with colorectal cancer

BACKGROUND

The association between colorectal cancer (CRC) and obstructive sleep apnoea (OSA) has been attracting increasing attention. several studies had confirmed that OSA increases the risk of CRC onset. However, the findings of studies on the morbidity of OSA in patients with CRC were unclear. Therefore, this study aimed to investigate the morbidity of OSA in patients with CRC as well as the association between the clinicopathological characteristics of OSA and CRC.

METHODS

A total of 414 patients with a pathological diagnosis of CRC from 1 January, 2020 to 30 December, 2020 were included in this study. Demographic characteristics, clinical information, and tumor characteristics of participants were collected; sleep was monitored using a wearable oximeter and via sleep quality questionnaire. The oxygen desaturation index (ODI) was used to classify OSA severity so that the diagnostic criteria for OSA were set based on the ODI as 0-5 (normal) and ≥5 (abnormal). After correcting for confounding factors, a logistic regression analysis was performed to calculate the odds ratio (OR) and 95% confidence interval (CI) for the factors affecting the tumor lymph node stage (N stage).

RESULTS

A total of 402 patients with CRC were included in this study, including 225 (55.97%) men and 177 (44.03%) women. The mean ODI value of participants was 3.40±8.17. The morbidity of OSA among the patients with CRC having ODI ≥5 was 16.17%. A comparison between the normal and abnormal ODI value groups revealed that the high proportion of abnormal ODI was related to higher N stage (P<0.05). Logistic regression analysis revealed a correlation of ODI values and age to the N stage. Specifically, CRC patients with an abnormal ODI had a higher risk of lymph node metastasis compared to those with normal ODI (OR =1.915, 95% CI: 1.025 to 3.579). Moreover, patients with CRC aged ≥65 years had a higher risk of lymph node metastasis compared to those aged <65 years (OR =2.190, 95% CI: 1.163 to 4.125).

CONCLUSIONS

CRC patients with abnormal ODI are susceptible to OSA. Additionally, abnormal ODI and age ≥65 years are relevant factors for the N2 stage.

Patient-Reported Outcome-Based Symptom Management Versus Usual Care After Lung Cancer Surgery: A Multicenter Randomized Controlled Trial

PURPOSE

We aimed to evaluate the efficacy and feasibility of patient-reported outcome (PRO)-based symptom management in the early period after lung cancer surgery.

METHODS

Before surgery, patients with clinically diagnosed lung cancer were randomly assigned 1:1 to receive postoperative PRO-based symptom management or usual care. All patients reported symptoms on MD Anderson Symptom Inventory-Lung Cancer presurgery, daily postsurgery, and twice a week after discharge for up to 4 weeks via an electronic PRO system. In the intervention group, treating surgeons responded to overthreshold electronic alerts driven by any of the five target symptom scores (score ≥ 4 on a 0-10 scale for pain, fatigue, disturbed sleep, shortness of breath, and coughing). The control group patients received usual care and no alerts were generated. The primary outcome was the number of symptom threshold events (any target symptom with a score of ≥ 4) at discharge. Per-protocol analyses were conducted.

RESULTS

Of the 166 participants, 83 were randomly allocated to each group. At discharge, the intervention group reported fewer symptom threshold events than the control group (median [interquartile range], 0 [0-2] v 2 [0-3]; P = .007). At 4 weeks postdischarge, this difference was maintained between the intervention and control groups (median [interquartile range], 0 [0-0] v 0 [0-1]; P = .018). The intervention group had a lower complication rate than the control group (21.5% v 40.6%; P = .019). Surgeons spent a median of 3 minutes managing an alert.

CONCLUSION

PRO-based symptom management after lung cancer surgery showed lower symptom burden and fewer complications than usual care for up to 4 weeks postdischarge.

Identifying classes of the pain, fatigue, and depression symptom cluster in long-term prostate cancer survivors-results from the multi-regional Prostate Cancer Survivorship Study in Switzerland (PROCAS)

PURPOSE

Aside from urological and sexual problems, long-term (≥5 years after initial diagnosis) prostate cancer (PC) survivors might suffer from pain, fatigue, and depression. These concurrent symptoms can form a cluster. In this study, we aimed to investigate classes of this symptom cluster in long-term PC survivors, to classify PC survivors accordingly, and to explore associations between classes of this cluster and health-related quality of life (HRQoL).

METHODS

Six hundred fifty-three stage T1-T3N0M0 survivors were identified from the Prostate Cancer Survivorship in Switzerland (PROCAS) study. Fatigue was assessed with the EORTC QLQ-FA12, depressive symptoms with the MHI-5, and pain with the EORTC QLQ-C30 questionnaire. Latent class analysis was used to derive cluster classes. Factors associated with the derived classes were determined using multinomial logistic regression analysis.

RESULTS

Three classes were identified: class 1 (61.4%) - "low pain, low physical and emotional fatigue, moderate depressive symptoms"; class 2 (15.1%) - "low physical fatigue and pain, moderate emotional fatigue, high depressive symptoms"; class 3 (23.5%) - high scores for all symptoms. Survivors in classes 2 and 3 were more likely to be physically inactive, report a history of depression or some other specific comorbidity, be treated with radiation therapy, and have worse HRQoL outcomes compared to class 1.

CONCLUSION

Three distinct classes of the pain, fatigue, and depression cluster were identified, which are associated with treatment, comorbidities, lifestyle factors, and HRQoL outcomes. Improving classification of PC survivors according to severity of multiple symptoms could assist in developing interventions tailored to survivors' needs.

Change in symptom clusters perioperatively in patients with lung cancer

PURPOSE

To describe the trajectory, number, and types of symptom clusters at three time points (i.e., day of admission [T1], 2-4 days postoperatively [T2], and 1 month postoperatively [T3]) using ratings of symptom occurrence and severity and to identify the changes in these symptom clusters over time in patients with lung cancer.

METHODS

We analysed the data of 217 lung cancer patients who received surgical treatment at a tertiary hospital affiliated to Anhui Medical University, in Hefei City, China. The occurrence and severity of 19 symptoms at all points of measurement were measured using the general and lung cancer modules of the M.D. Anderson Symptom Inventory. Exploratory factor analysis was performed to extract the symptom clusters.

RESULTS

Seven symptom clusters were identified across symptom dimensions. However, only three of them (i.e., lung cancer specific, sleep disturbance, and nervous system) were relatively stable across dimensions and time. Two symptom clusters varied over time but not with dimensions (nutritional and gastrointestinal). The other two symptom clusters (psychological and respiratory) differed in terms of time and dimensions.

CONCLUSIONS

Findings may provide insights into the seven identified clusters and overall stability of three symptom clusters in lung cancer patients perioperatively.

Symptom Clusters in Head and Neck Cancer: A Systematic Review and Conceptual Model

OBJECTIVE

The two approaches to symptom-cluster research include grouping symptoms and grouping patients. The objective of this systematic review was to examine the conceptual approaches and methodologies used in symptom-cluster research in patients with head and neck cancer.

DATA SOURCES

Articles were retrieved from electronic databases (CINAHL, MEDLINE via Ovid, APA PsycINFO, Scopus, Embase, and Cochrane Central Register of Controlled Trials-CENTRAL), five grey literature portals, and Google Scholar. Seventeen studies met the eligibility criteria. Eight studies grouped symptoms to identify symptom clusters, of which two used qualitative methods. The number of symptom clusters ranged from two to five, and the number of symptoms in a cluster ranged from 2 to 11. Nine studies grouped patients based on their experiences with multiple symptoms. Cluster analysis and factor analysis were most commonly used. Despite variable names and composition of symptom clusters, synthesis revealed three prominent symptom clusters: general, head and neck cancer-specific, and gastrointestinal. Being female and quality of life were significantly associated with high symptom group or cluster severity. Biological mechanisms were sparsely examined.

CONCLUSION

Symptom cluster research in head and neck cancer is emerging. Consensus on nomenclature of a symptom cluster will facilitate deduction of core clinically relevant symptom clusters in head and neck cancer. Further research is required on understanding patients' subjective experiences, identifying predictors and outcomes, and underlying mechanisms for symptom clusters.

IMPLICATIONS FOR NURSING PRACTICE

Identification of clinically relevant symptom clusters would enable targeted symptom assessment and management strategies, thus improving treatment efficiencies and patient outcomes.

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.

Relationship Between Symptom Distress and Fatigue Characteristics in Patients with Gastric Cancer During 1 Month after Gastrectomy

This study's purpose was to describe changes in symptom distress and fatigue characteristics identifying which symptoms significantly impacted fatigue characteristics of patients with Gastric Cancer (GC) within 1 month after gastrectomy. A prospective longitudinal study was conducted. Patients with GC who were scheduled for gastrectomy were recruited from surgical outpatient clinics and surgery wards in northern Taiwan. Data were collected using a set of questionnaires before (T0) and 7 (T1) and 28 days (T2) after gastrectomy. Over all, 86 patients experienced mild levels of fatigue and symptom distress. The changes in worst fatigue and fatigue interference were greatest at T1. Anxiety had a significant negative effect on both worst fatigue and fatigue interference. Dry mouth, pain, and body image had significant deleterious effects on worst fatigue. The co-occurring symptoms affecting fatigue for patients with GC in the acute phase after gastrectomy should be actively assessed to ensure optimal fatigue management.

A comparative cross-sectional study on sleep quality in patients with a history of differentiated thyroid carcinoma and its correlation with quality of life

PURPOSE

To evaluate sleep quality in differentiated thyroid carcinoma (DTC) patients and correlate sleep disturbances with quality of life (QoL).

METHODS

119 DTC patients were enrolled (DTC group). The Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI) inventories were administered. The Thyroid-specific Patient-Reported Outcome (ThyPRO) questionnaire, the Billewicz scale (BS) and an ad-hoc visual analogic scale (VAS) were used to measure QoL and subjective therapy-related complaints. The same examinations were conducted in 53 subjects (control group) who had undergone surgery for benign thyroid pathology.

RESULTS

L-T4 dosages and TSH levels differed between the groups. BS and VAS scores were comparable. PSQI documented a similar percentage of poor sleepers in the DTC (74%) and control (62%) groups. ISI showed no difference in subjects without clinically significant insomnia: DTC (43%) and controls (48%). ThyPRO showed significantly worse scores in DTC than control subjects. In DTC patients, PSQI (P = 0.002) and ISI (P = 0.04) correlated significantly with age. In control subjects, TSH displayed a significant positive association with PSQI (P = 0.02) and ISI (P < 0.05). The ThyPRO general score correlated significantly with PSQI in DTC patients. In both groups, ISI correlated significantly with several ThyPRO scales and the ThyPRO general score. "Anxiety" and "emotional susceptibility" were the scales most significantly related with PSQI and ISI.

CONCLUSION

In disease-free DTC patients and subjects who undergo thyroid surgery for benign pathology, abnormal sleep components and insomnia are similar. The ThyPRO questionnaire closely reflects sleep disturbances in all subjects. Recognising and treating sleep disturbances might improve QoL.

Sleep and quality of life in lung cancer patients and survivors

BACKGROUND

Lung cancer patients and survivors are vulnerable to disturbed sleep and impaired quality of life (QOL) across the continuum of illness. Few studies have sought to identify predictors of QOL using well-validated measures of both sleep quality and QOL in this population.

PURPOSE

The purpose of this study was to examine factors associated with lung cancer that are predictive of QOL in adult lung cancer patients and survivors in the outpatient setting.

METHOD

Cross-sectional data collected exclusively in the outpatient setting from three lung cancer clinics in the Northeastern United States were pooled and analyzed. The pooled sample (N = 103) data included cancer type and stage, body mass index, Pittsburgh Sleep Quality Index, and Functional Assessment of Cancer Treatment-Lung information.

RESULTS

Significant correlations between sleep quality, lung cancer symptom severity, and QOL were observed. Sleep quality and lung cancer symptoms were found to be statistically significant predictors of QOL. No significant differences in QOL were found based on cancer type or recruitment source. Demographic factors and cancer stage were also not predictive of overall QOL.

CONCLUSIONS

Lung cancer symptoms and sleep quality were important determinants of QOL in this pooled sample of lung cancer patients and survivors.

IMPLICATIONS FOR PRACTICE

Patients and survivors of lung cancer require routine screening for sleep disturbance, lung cancer symptoms, and QOL needs. Nurse practitioners can help improve QOL in this population by screening for and treating sleep disturbance and lung cancer symptoms.

Interactions of Spiritual Well-Being, Symptoms, and Quality of Life in Patients Undergoing Treatment for Non-Small Cell Lung Cancer: A Cross-Sectional Study

OBJECTIVES

To investigate the relationship of spiritual well-being and quality of life (QOL) in patients undergoing treatment for non-small cell lung cancer (NSCLC) and to identify the role of four different symptoms (ie, appetite loss, dyspnea, pain, and fatigue) in mediating this relationship DATA SOURCES: A total of 132 consecutive patients undergoing chemotherapy, radiotherapy, or concurrent chemoradiotherapy for NSCLC from National University Hospital were examined. Symptoms were assessed using the symptom subscale of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-C30 (QLQ-C30). Spiritual well-being was assessed using the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being scale. Global QOL was assessed using the item on global health status from the European Organization for Research and Treatment of Cancer. Data of all self-reported surveys were analyzed using serial multiple mediation analysis.

CONCLUSION

Spiritual well-being directly affected QOL in patients undergoing treatment for NSCLC. In addition, a serial multiple mediation model showed causal relationships of spiritual well-being on appetite loss, appetite loss on dyspnea, dyspnea on pain, pain on fatigue, and fatigue on QOL.

IMPLICATIONS FOR NURSING PRACTICE

Providing integrated care that considers spiritual well-being may improve the QOL of patients undergoing treatment for NSCLC. Our findings emphasized the need to conduct routine assessments of spiritual well-being and symptoms when characterizing patient QOL.

Exercise prehabilitation in lung cancer: Getting stronger to recover faster

Despite several recent advances, lung cancer surgery is still associated with potentially severe postoperative complications. It has been suggested that preoperative exercise training could render patients with borderline functional parameters eligible for surgery, improve perioperative outcomes and that these benefits might reduce healthcare costs. Nevertheless, given the substantial heterogeneity of the available studies, no specific guidelines for preoperative exercise training have been released so far. This narrative review aims to provide an overview of the potential benefits of exercise training in the preoperative period as a central intervention for lung cancer patients. In detail, the effects of exercise (with different regimens) were evaluated in terms of physical functions, patients' eligibility for curative surgery, postoperative complications and length of stay, with an exploratory focus on healthcare costs and long-term outcomes. Furthermore, a feasible approach for every-day clinical practice is proposed in order to increase the expected benefit deriving from a more extensive and methodical application of prehabilitation exercise, ideally in the context of a comprehensive approach to lung cancer patients, including nutritional and psychological support.

Unwelcome Companions: Loneliness Associates with the Cluster of Pain, Fatigue, and Depression in Older Adults

Objective: Pain, fatigue, and depression commonly co-occur as a symptom cluster in pathological inflammatory states. Psychosocial stressors such as loneliness may lead to similar states through shared mechanisms. We investigated the association of loneliness with pain, fatigue, and depression in older adults. Methods: Using Health and Retirement Study data (N = 11,766), we measured cross-sectional prevalence of frequent, moderate to severe pain; severe fatigue; depressive symptoms; and co-occurrence of symptoms surpassing threshold levels (i.e., symptom cluster). Logistic regression models evaluated associations with loneliness. Results: Pain, fatigue, and depression were reported in 19.2%, 20.0%, and 15.3% of the total sample, respectively. The symptom cluster was seen in 4.9% overall; prevalence in lonely individuals was significantly increased (11.6% vs. 2.3%, p < .0001). After adjusting for demographic variables, loneliness associated with the symptom cluster (adjusted OR = 3.39, 95% CI = 2.91, 3.95) and each symptom (pain adjusted OR = 1.61, 95% CI = 1.48, 1.76; fatigue adjusted OR = 2.02, 95% CI = 1.85, 2.20; depression adjusted OR = 4.34, 95% CI = 3.93, 4.79). Discussion: Loneliness strongly associates with the symptom cluster of pain, fatigue, and depression. Further research should examine causal relationships and investigate whether interventions targeting loneliness mitigate pain, fatigue, and depression.

Cancer pain and lower functional status predict poor trajectories of symptom and fatigue distress in patients with lung cancer

OBJECTIVE

To identify distinct subgroups of patients newly diagnosed with lung cancer (LC) over time and to explore the predictors of distinct trajectories of symptom and fatigue distress in LC patients.

METHODS

A total of 120 patients newly diagnosed with LC were recruited in this longitudinal prospective study. Our survey investigated patients' symptoms in 6 months. Latent growth curve analysis (LGCA) was conducted to identify patients with distinct trajectories of symptom and fatigue distress. The characteristics of the patients among groups were compared for statistical differences by the chi-square test or ANOVA.

RESULTS

The results of LGCA revealed that the linear three-trajectory model had the best model fit for symptom and fatigue distress. Patients' symptom and fatigue distress improved with time, except for patients with increasing trajectories. Patients' trajectories of symptom and fatigue distress were affected by pain, lower functional status, total symptom score and depression. Moreover, patients with increasing trajectories of symptom and fatigue distress experienced more pain, physiological symptoms and depression from 1 to 6 months.

CONCLUSIONS

Pain and functional status were the major factors that deteriorated the recovery of trajectory in symptom distress and fatigue distress among patients with increasing trajectories.

Evaluation of Subjective Sleep Disturbances in Cancer Patients: A Cross-Sectional Study in a Radiotherapy Department

Background: The factors associated with sleep disturbances in cancer patients remains unclear. This study aimed to explore the prevalence of sleep disorders and predictors associated with sleep disturbance in cancer patients from a radiotherapy department. Methods: Patients with cancers were recruited before the start of radiotherapy from our institution between January 2019 and February 2020. Pittsburgh Sleep Quality Index (PSQI) scale was used to assess sleep quality. Descriptive statistics, Chi-square test, and multivariate logistic regression analysis were used to conduct statistical analysis. Results: A total of 330 eligible patients were included. Of them, 38.3% (n = 127) had the globe PSQI score >7, indicating that they suffered from sleep disorders. Patients with lung cancer (45.2%) were more likely to suffer from sleep disturbance, followed by cervical cancer (43.8%), nasopharyngeal carcinoma (41.7%), esophageal cancer (41.5%), breast cancer (37.7%), and colorectal cancer (30%). With regard to the PSQI components, the mean sleep duration was 8 h, 20.3% (n = 67) of them reported poor subjective sleep quality, 6.1% (n = 20) needed medication to improve sleep, and 53.6% (n = 177) suffered daytime dysfunction. Multivariate logistic regression models showed body mass index (BMI) ≥ 20 kg/m² [odds ratio (OR) 0.599, 95% confidence interval (CI) 0.329-0.948, P = 0.031] and the receipt of surgery (OR 0.507, 95% CI 0.258-0.996, P = 0.048) were the significant favorable predictors for sleep disturbance, while age, gender, marital status, education level, comorbidity, metastasis status, diagnostic status, and cancer type were not significantly associated with sleep disturbance. Conclusions: Approximately 40% of the cancer patients suffer from sleep disturbance before the start of radiotherapy. Patients with BMI ≥ 20 kg/m² and receiving surgery are less likely to develop sleep disturbance in comparison with others.

Relationships of Symptom Groups and Functioning Domains in Patients with Advanced-Stage Non-Small Cell Lung Cancer Undergoing Treatment: A Cross-Sectional Study

The purpose of this study was to describe the symptoms experienced by patients with non-small cell lung cancer (NSCLC), examine whether different symptom groups significantly affected different functioning domains in these patients, and determine the effect of the "lack of energy" and "pain" symptom groups on the different functioning domains of health-related quality of life (HRQOL). From a single tertiary institution, this cross-sectional study enrolled 135 consecutive NSCLC patients who were mostly undergoing chemotherapy and were in the advanced stage (National University Hospital, Daegu, South Korea). Clinical and self-reported demographic information and data on different functioning domains (from the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30)), symptom experience (from the EORTC QLQ-LC13), and the Symptom Distress Scale (SDS) were examined. The four most common symptoms were fatigue (69%), pain (47%), dyspnea (38%), and lack of appetite (36%). The "pain" symptom group was negatively associated with physical, emotional, cognitive, and role functioning. The "lack of energy" symptom group was negatively associated with physical, role, emotional, social, and cognitive functioning. The "lack of energy" symptom group explained the most variance for physical and role functioning, and the "pain" symptom group explained the most variance for emotional functioning. Impaired concentration explained the most variance for cognitive functioning.

[Applying Extended Theory of Planned Behavior for Lung Cancer Patients Undergone Pulmonary Resection: Effects on Self-Efficacy for Exercise, Physical Activities, Physical Function, and Quality of Life]

PURPOSE

This study aims to examine the effects of nursing interventions based on the Extended Theory of Planned Behavior (ETPB) regarding self-efficacy for exercise (SEE), physical activity (PA), physical function (PF), and quality of life (QOL) in patients with lung cancer who have undergone pulmonary resection.

METHODS

This quasi-experimental study was conducted between July 2015 and June 2018 in two university-affiliated hospitals. The intervention included pre-operative patient education, goal setting (action and coping planning), and feedback (behavior intention and perceived behavioral control). The intervention group (IG) (n=51) received nursing interventions from the day before surgery to 12 months after lung resection, while the comparison group (CG) (n=36) received usual care. SEE, PA, PF (dyspnea, functional status, and 6-minute walking distance [6MWD]), and QOL were measured before surgery and at one, three, six, and 12 months after surgery. Data were analyzed using the χ² test, Fisher's exact test, Mann-Whitney U test, t-test, and generalized estimation equations (GEE).

RESULTS

There were significant differences between the two groups regarding SEE (χ²=13.53, p=.009), PA (χ²=9.51, p=.049), functional status (χ²=10.55, p=.032), and 6MWD (χ²=15.62, p=.004). Although there were no time or group effects, the QOL mental component (Z=-2.78, p=.005) of the IG was higher than that of the CG one month after surgery. Interventions did not affect dyspnea or the QOL physical component.

CONCLUSION

The intervention of this study was effective in improving SEE, PA, functional status, and 6MWD of lung cancer patients after lung resection. Further extended investigations that utilize ETPB are warranted to confirm these results.

One-Year Quality of Life Trends in Early-Stage Lung Cancer Patients After Lobectomy

Objective: Quality of Life (QoL) is an important predictor of patient's recovery and survival in lung cancer patients. The aim of the present study is to identify 1-year trends of lung cancer patients' QoL after robot-assisted or traditional lobectomy and investigate whether clinical (e.g., pre-surgery QoL, type of surgery, and perioperative complications) and sociodemographic variables (e.g., age) may predict these trends.

Methods: An Italian sample of 176 lung cancer patients undergoing lobectomy completed the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire—Core 30 (QLQ-C30) at the pre-hospitalization (t0), 30 days (t1), 4 months (t2), 8 months (t3), and 12 months (t4) after surgery. Sociodemographic and clinical characteristics (age, gender, perioperative complications, and type of surgery) were also collected. The individual change over time of the 15 dimensions of the EORTC QLQ-C30 and the effects of pre-surgery scores of QoL dimensions, type of surgery, perioperative complications, and age on patients' QoL after surgery were studied with the individual growth curve (IGC) models.

Results: Patients had a good recovery after lobectomy: functioning subscales improved over time, while most of the symptoms became less severe over the care process. Perioperative complications, type of surgery, pre-surgery status, and age significantly affected these trends, thus becoming predictors of patients' QoL.

Conclusion: This study highlights different 1-year trends of lung cancer patients' QoL. The measurement of pre- and post-surgery QoL and its clinical and sociodemographic covariables would be necessary to better investigate patients' care process and implement personalized medicine in lung cancer hospital divisions.

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.

Advanced psychometric testing on a clinical screening tool to evaluate insomnia: sleep condition indicator in patients with advanced cancer

Purpose

To examine the psychometric properties of the Sleep Condition Indicator (SCI) using different psychometric approaches [including classical test theory, Rasch models, and receiver operating characteristics (ROC) curve] among patients with advanced cancer.

Methods

Through convenience sampling, patients with cancer at stage III or IV (n = 859; 511 males; mean ± SD age = 67.4 ± 7.5 years) were recruited from several oncology units of university hospitals in Iran. All the participants completed the SCI, Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Hospital Anxiety and Depression Scale (HADS), General Health Questionnaire (GHQ), and Edmonton Symptom Assessment Scale (ESAS). In addition, 491 participants wore an actigraph device to capture objective sleep.

Results

Classical test theory [factor loadings from confirmatory factor analysis = 0.76–0.89; test–retest reliability = 0.80–0.93] and Rasch analysis [infit mean square (MnSq) = 0.63–1.31; outfit MnSq = 0.61–1.23] both support the construct validity of the SCI. The SCI had significant associations with ISI, PSQI, ESS, HADS, GHQ, and ESAS. In addition, the SCI has satisfactory area under ROC curve (0.92) when comparing a gold standard of insomnia diagnosis. Significant differences in the actigraphy measure were found between insomniacs and non-insomniacs based on the SCI score defined by ROC.

Conclusion

With the promising psychometric properties shown in the SCI, healthcare providers can use this simple assessment tool to target the patients with advanced cancer who are at risk of insomnia and subsequently provide personalized care efficiently.

Somatic Acupoint Stimulation for Cancer-Related Sleep Disturbance: A Systematic Review of Randomized Controlled Trials

Aim

The aim of this systematic review was to analyze and synthesize available evidence for the effects of somatic acupoint stimulation (SAS) on cancer-related sleep disturbance in adults with cancer.

Methods

Nine databases and four clinical trial registries were searched from their inception to July 2019 to identify potential articles and registered trials. Two authors independently extracted data and appraised the methodological quality of the included studies. The included studies could not be subjected to meta-analysis due to the significant variations in SAS intervention protocols and outcome measurement instruments. This systematic review therefore reported the results of the included trials narratively.

Results

Seven studies were identified, which involved 906 cancer patients. SAS protocols varied across trials without an optimal evidence-based standard intervention protocol to manage cancer-related sleep disturbance. Sanyinjiao (SP6) was the most commonly selected acupoint. Manual acupuncture was typically 15–30 min in duration and was conducted once a day or once a week for a period of 1–5 weeks, whereas self-administered acupressure was typically 1–3 min in duration per point and was conducted once a day, such as during night time before going to bed, for a period of 1–5 months. The results indicated that SAS could potentially relieve cancer-related sleep disturbance and improve quality of life. Mild adverse effects were reported in three of the included studies, but none of them performed a causality analysis to clarify the association between the reported adverse events and the intervention.

Conclusions

This systematic review showed that SAS is a useful approach to relieving cancer-related sleep disturbance. However, research evidence on SAS for managing cancer-related sleep disturbance has not been fully conclusive due to the limited number of existing clinical studies with relatively small sample size and suboptimal methodological quality. Clinical trials with large sample size and robust methodology are warranted in future research.

Severe functional limitation due to pain & emotional distress and subsequent receipt of prescription medications among older adults with cancer

BACKGROUND

Certain cancer types and subsequent treatment can cause or worsen pain and emotional distress, leading to functional limitation, particularly among a growing population of older adults with cancer.

METHODS

We constructed a national sample of older adult Medicare beneficiaries with cancer using the 2007-2012 Surveillance, Epidemiology and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) database linked to Medicare Part D enrollment and prescription claims data. MHOS survey responses described functional limitations due to pain and emotional distress. Using multivariable logistic regression, we estimated the association between participant characteristics and patient-reported functional limitation due to pain and emotional distress and subsequent prescription medication use.

RESULTS

Among 9105 older adults with cancer, aged 66-102 years (y), 68.6% reported moderate to severe functional limitation due to pain, and 48.3% reported moderate to severe functional limitation due to emotional distress. Nearly 10% reported severe functional limitation due to co-occurring symptoms of pain and emotional distress. Significant predictors of severe functional limitation due to co-occurring symptoms included age ≥ 80y (ref: 66-69y, adjusted relative risk (aRR): 1.74; 95% confidence interval (CI) 1.39-2.18, p < .001), stage IV disease at diagnosis (ref: stage I, aRR: 2.08; CI 1.52-2.86, p < .001), and lung cancer (ref: breast cancer, aRR: 1.84; CI 1.30-2.61, p < .001). Among 892 participants reporting co-occurring symptoms, 32.5% received neither pain nor emotional distress prescription medication.

CONCLUSIONS

Functional limitation due to pain and emotional distress persist among older adults with cancer, particularly octogenarians. Efforts to identify and target unmet supportive care needs to maintain functional independence are needed.

The Correlative Strength of Objective Physical Assessment Against the ECOG Performance Status Assessment in Individuals Diagnosed With Cancer

BACKGROUND

Individuals with cancer experience loss of function and disability due to disease and cancer-related treatments. Physical fitness and frailty influence treatment plans and may predict cancer outcomes. Outcome measures currently used may not provide sufficiently comprehensive assessment of physical performance.

OBJECTIVE

The objectives of this study are to: (1) describe the development of a functional measure, the Bellarmine Norton Assessment Tool (BNAT), for individuals with cancer; and (2) assess the relationship between the BNAT and the Eastern Cooperative Oncology Group (ECOG) Performance Status, a commonly used classification system by oncologists.

DESIGN

This was a prospective cohort correlation study.

METHODS

The BNAT encompasses 1 self-reported physical activity question and 4 objective tests: 2-Minute Step Test, 30-Second Sit to Stand, Timed Arm Curl, and Timed Up and Go. The BNAT score and its components were compared with ECOG Performance Status scores assigned by oncologists and analyzed for correlation and agreement.

RESULTS

A total of 103 male and female individuals (ages 33-87 years) with various cancer diagnoses participated. The mean (SD) ECOG Performance Status score was 0.95 (0.87), range 0 to 3, and the mean BNAT score was 14.9 (4.3), range 5 to 24. Spearman agreement association of BNAT and ECOG Performance Status scores revealed a significant moderate negative relationship (r = -0.568).

LIMITATIONS

The BNAT was compared with the ECOG Performance Status, a commonly used but subjective measure. Additionally, a common data set was used for both deriving and evaluating the BNAT performance scale.

CONCLUSIONS

There was a moderate negative linear relationship of BNAT to ECOG Performance Status scores across all participants. Utilization of the BNAT may reflect overall physical performance and provide comprehensive and meaningful detail to influence therapeutic decisions.

Impact of pre-radiation therapy quality of life in lung cancer survival: a prospective, intention-to-treat, multicenter study

PURPOSE

Lung cancer (LC) has a significant impact on patients' health-related quality of life (HRQoL). We investigate the correlations between pre-radiation therapy HRQoL and survival.

MATERIALS AND METHODS

A prospective, intention-to-treat, multicentre study of 437 patients with LC recruited at the radiation oncology departments of three different institutions was conducted between 2012 and 2016. QoL was assessed using the EORTC-QLQ-C30 (v3.0) and EORTC-QLQ-LC13 questionnaires. Global health status (GHS), physical (PF), role functioning (RF), emotional (EF), cognitive (CF), and social functioning (SF) as well as symptoms scores were evaluated in univariate and multivariate analyses.

RESULTS

The cohort consisted of 376 men (86%) and 61 women, with a median age of 66 years (range 31-88). Histology was: 72% (n = 315) non-small cell lung cancer and 28% small cell lung cancer. The most common stage was III (80%) and the median follow-up for alive patients was 30 months (range 7-76). Multivariate analysis showed that RF was associated with a lower risk of mortality (HR: 0.693; p = 0.008) and recurrence (HR: 0.737; p = 0.040). Additionally, lower scores on EF and PF were associated with higher mortality (HR: 0.696; p = 0.003 and HR: 0.765; p = 0.044, respectively). Appetite loss, constipation, and dysphagia were associated with a higher risk of mortality (HR: 1.985; p < 0.001, HR: 1.373; p = 0.036, and HR: 1.659; p = 0.002, respectively), while appetite loss was the only symptom associated with a higher risk of recurrence (HR: 1.525; p = 0.014).

CONCLUSIONS

Pre-radiation therapy scores on RF, EF, and PF and symptoms like appetite loss, dysphagia, and constipation were associated with the risk of mortality. This information could be added to other prognostic factors to guide our treatment decisions.

Effects of Transcutaneous Electrical Acupoint Stimulation on the Postoperative Sleep Quality and Pain of Patients After Video-Assisted Thoracoscopic Surgery: A Prospective, Randomized Controlled Trial

OBJECTIVE

Postoperative sleep disturbances have serious adverse effects on postoperative outcomes. Our paper aimed to observe the effect of using transcutaneous electrical acupoint stimulation (TEAS) on sleep quality and complications after surgery in patients undergoing selective video-assisted thoracoscopic surgery.

PATIENTS AND METHODS

Eighty-five patients were divided into the TEAS group or the control group randomly. Thirty minutes of TEAS treatment was performed on TEAS group at the following time points: the first night before surgery, at the end of surgery, and before sleeping on the second and third nights after surgery. The Portable Sleep Monitor (PSM) was performed to determine the sleep quality of the two nights before the operation (Sleep preop 2 and Sleep preop 1) and the first and third night after surgery (Sleep POD 1 and Sleep POD 3). The visual analog scale (VAS) was performed to evaluate pain scores after surgery and the Athens Insomnia Scale (AIS) was used for evaluating subjective sleep quality.

RESULTS

Participants in the TEAS group had a lower AIS score and higher sleep efficiency at each time point except Sleep preop 2. Participants in the TEAS group showed significantly higher proportion of each sleep stage during Sleep-preop 1, Sleep POD 1, and Sleep POD 3. Patients in the TEAS group had significantly lower VAS scores at 2, 4, and 6 h during the first 24 h after surgery. The incidence of nausea and vomiting and dizziness in the control group was statistically higher than in the TEAS group.

CONCLUSION

Patients usually have sleep disturbances after video-assisted thoracoscopic surgery, such as decreased distribution of each sleep stage, lower sleep efficiency, and higher AIS score. Undergoing TEAS treatment perioperatively can improve sleep quality, and effectively promote the postoperative analgesic effect and alleviate postoperative complications.
