Postoperative Symptom Burden in Patients Undergoing Lung Cancer Surgery

Postoperative symptom network analysis in non-small cell lung cancer patients: a cross-sectional study

OBJECTIVE

To investigate the incidence and severity of symptoms in postoperative non-small-cell lung cancer patients undergoing thoracoscopic surgery, construct a symptom network, and analyze centrality indicators of the network to identify core symptoms and provide a basis for precise symptom management.

METHODS

A convenience sampling method was used to select postoperative NSCLC patients from the Department of Thoracic Surgery at the First Affiliated Hospital of Army Medical University between September 2024 and December 2024. The Chinese version of the Anderson Symptom Inventory Core Symptom Module and the revised Lung Cancer-Specific Symptom Module were used to survey the incidence and severity of symptoms. A symptom network was constructed with R software with the EBICgloss function and Spearman correlation analysis, and the centrality indicators were then calculated.

RESULTS

In total, 404 questionnaires were distributed, and 367 valid questionnaires were returned (effective response rate, 90.8%). The top three symptoms in terms of incidence and severity during the postoperative hospitalization of NSCLC patients were pain (100%), fatigue (99%), and shortness of breath (98%). The results of the centrality indicators of the symptom network revealed that the top three symptoms in terms of strength centrality were shortness of breath (rs = 5.44), fatigue (rs = 5.43), and pain (rs = 5.34).

CONCLUSION

Postoperative NSCLC patients experience various symptoms, with shortness of breath being the core symptom. Targeted intervention strategies are needed to improve the efficiency and accuracy of symptom management, reduce the symptom burden on patients, and increase their quality of life.

Ninjin'yoeito improves respiratory symptoms after lung cancer surgery: a prospective randomized study

PURPOSE

This study evaluated the efficacy of ninjin'yoeito for alleviating postoperative symptoms after lung cancer surgery.

METHODS

Overall, 140 patients who underwent lobectomy were randomized into a conventional treatment group and a ninjin'yoeito group. The primary endpoint was change in the Cancer Fatigue Scale (CFS) score from baseline and the secondary endpoints were the Cancer Dyspnea Scale (CDS) scores, the Kihon Checklist, and respiratory function.

RESULTS

The mean change in the CFS score 8 weeks postoperatively was - 5.56 in the ninjin'yoeito group and - 5.53 in the conventional treatment group (P = 0.425), but this outcome did not meet the primary endpoint. Changes in the mean CDS scores 8 weeks postoperatively were - 5.60 and - 3.38 in the ninjin'yoeito and conventional groups, respectively, with a difference of - 1.95 (P = 0.049). The changes in the mean vital capacity 8 weeks postoperatively were - 340.5 mL in the ninjin'yoeito group and - 473.5 mL in the conventional treatment group, with a difference of + 135.1 mL (P = 0.041). The ninjin'yoeito group had a significantly lower proportion of patients with malnutrition 16 weeks postoperatively than the conventional treatment group (P = 0.040).

CONCLUSION

The results of this study show that ninjin'yoeito is effective for alleviating respiratory symptoms and improving malnutrition after lung cancer surgery.

Sex-related differences in postoperative patient-reported outcomes among lung cancer patients: a multicenter cohort study

BACKGROUND

Studies on sex-related differences in post-lung cancer surgery symptoms are limited. Understanding these differences may provide insights into patient recovery. Therefore, we investigated sex-related differences in these symptoms and their underlying associated factors.

METHODS

We included patients aged ≥ 18 years undergoing surgery for lung cancer from a multicenter cohort study (CN-PRO-Lung 1) that focused on postoperative lung cancer symptoms trajectories. On a daily assessment schedule, we evaluated patients' symptoms and their impact on functioning from the day before surgery until discharge using the MD Anderson Symptom Inventory-Lung Cancer module. We evaluated sex-related differences in symptom scores over time and identified influencing factors using linear mixed models.

RESULTS

Of 372 eligible patients (196 men and 176 women;) symptoms were milder in men than in women for pain (estimate = 0.427, P = 0.021), fatigue (estimate = 1.071, P < 0.001), shortness of breath (estimate = 0.431, P = 0.021), lack of appetite (estimate = 0.728, P < 0.001), dry mouth (estimate = 0.438, P = 0.015), and constipation (estimate = 0.887, P < 0.001) during postoperative hospitalization (median: 7 days). Pain scores decreased over time in both sexes (estimate = -0.440 in men, P < 0.001; -0.510 in women, P < 0.001), while different factors were associated with increased pain in each group. In men, higher American Society of Anesthesiologists (ASA) classification (estimate = 0.430, P = 0.035), advanced pTNM stage (estimate = 0.550, P = 0.007), and having more than one chest drain (estimate = 0.690, P = 0.001) were associated with greater pain. In women, systematic lymph node dissection was associated with increased pain (estimate = 0.700, P = 0.033).

CONCLUSIONS

Women reported a higher symptom burden than men in the early postoperative period after lung cancer surgery. Key factors associated with worse postoperative pain include higher ASA classification, advanced pTNM stage, and more than one chest tube in men and systematic lymph node dissection in women.

Association of psychosocial risk factors with acute outcomes of elective cancer resection in the United States

BACKGROUND

Psychosocial risk factors, including psychiatric disorders, substance use, limited cognitive comprehension, and low socioeconomic or uninsured status, are increasingly recognized in cancer care. However, their independent effects on acute postoperative outcomes after elective cancer surgery remain unclear. This study evaluates the association between psychosocial risk factors and clinical and financial outcomes in patients undergoing cancer resections.

METHODS

All adult (≥18 years) records entailing elective resection for lung, esophageal, gastric, pancreatic, hepatic, and colon cancer were tabulated from the 2016-2021 Nationwide Readmissions Database. After entropy balancing, multivariable regression models were developed to ascertain the independent association of psychosocial risk factors. with mortality, complications, length of stay, and nonhome discharge.

RESULTS

Of ∼655,376 patients, 223,035 (34.2%) were considered to comprise psychosocial risk factors. Relative to others, the psychosocial risk factors cohort was more commonly female (51.9 vs 47.1%, P < .001), and had a greater Elixhauser Comorbidity Index (4 [3-5] vs 3 [2-4], P < .001). Both groups most frequently underwent resection for colectomy (51.9% vs 51.1%%, P < .001), yet those with psychosocial risk factors had greater rates of lobectomy (27.8% vs 25.8%, P < .001), compared with their counterparts. After entropy balancing, psychosocial risk factors were linked to greater odds of mortality (adjusted odds ratio, 1.43, 95% confidence interval, 1.31-1.57), respiratory (adjusted odds ratio, 1.25; 95% confidence interval, 1.21-1.31) and infectious (adjusted odds ratio, 1.17; 95% confidence interval, 1.12-1.21) complications. Furthermore, patients with psychosocial risk factors faced incrementally increased resource use.

CONCLUSION

Psychosocial risk factors independently predict adverse clinical and financial outcomes after elective cancer operations. Systematic screening for psychosocial risk factors may facilitate targeted interventions to improve care for high-risk patients.

Postoperative Symptom Cluster in NSCLC Patients and Its Relationship with Social Support and Self-Efficacy: A Cross-Sectional Study

Purpose

The study aimed to identify symptom clusters among NSCLC patients within 3 months postoperatively and analyze the relationships between symptom clusters and social support and self-efficacy.

Methods

We conducted a cross-sectional study from January 1 to May 31, 2024, involving NSCLC patients undergoing surgery at hospitals in Jiangsu Province. Data were collected using the MD Anderson Symptom Inventory, the Perceived Social Support Scale (PSSS), and the Strategies Used by People to Promote Health (SUPPH).

Results

Exploratory factor analysis revealed five distinct symptom clusters: respiratory distress, respiratory tract discomfort, physical exhaustion, digestive dysfunction, and nighttime disturbances. The severity of physical exhaustion and nighttime disturbances was negatively correlated with PSSS scores. Conversely, the severity of respiratory distress, respiratory tract discomfort, and digestive dysfunction symptoms was negatively correlated with SUPPH scores.

Conclusion

Our findings may guide medical professionals in managing postoperative symptoms in NSCLC patients. Social support and self-efficacy appear to be significant factors influencing the severity of symptom clusters.

Feasibility of postoperative home-based pulmonary function training for lung cancer patients: a real-world study

BACKGROUND

Pulmonary surgery can significantly impact patients' respiratory function and reduce their quality of life. Previous studies have shown that perioperative breathing exercises (BE) can facilitate the recovery of lung function and improve patients' quality of life after surgery. However, due to the lack of supervision and awareness, patients often struggle to adhere to the prescribed exercise regimen. This study statistics and analyzes the effect of postoperative respiratory function training on postoperative recovery of patients undergoing pneumonectomy in a realistic environment, in order to provide a basis for optimizing postoperative rehabilitation strategies.

METHODS

Patients undergoing surgical treatment for pulmonary nodules received standardized education upon admission, including guidance on performing breathing exercises. Preoperative pulmonary function tests (PFT) and arterial oxygen saturation measurements were conducted, and patients were instructed to return for follow-up pulmonary function and arterial oxygen saturation assessments at 1 month, 3 months, and 6 months post-surgery. In addition, patients were asked to complete online questionnaires at these time points. Oxygen saturation levels were also re-assessed before discharge, and patients were encouraged to complete a discharge questionnaire. Weekly phone calls were made to remind patients to continue their breathing exercises. The study analyzed 12 potential factors that might affect the outcomes, including preoperative nebulization use, surgical method, and patient age. The primary outcome measures were the effects of postoperative breathing exercises on FEV1, FVC, DLCO, and SPO2 at 1 month (T1), 3 months (T2), and 6 months (T3) post-surgery. Secondary outcomes included LCQ cough assessment, FACT-L quality of life assessment, evaluations of pain and appetite, SAS anxiety level, SDS depression level, AIS sleep quality, and the modified MRAC assessment of dyspnea symptoms.

RESULTS

The study initially enrolled 296 patients (T0), including 233 patients who underwent sublobar resection (SRP) and 63 patients who underwent lobectomy (LBP). Between T0 and T1, 203 patients remained in the SRP group and 47 in the LBP group. Between T0 and T2, 36 patients remained in the SRP group and 9 in the LBP group. By T3, the SRP group had 14 patients, and the LBP group had 5 patients remaining. Due to incomplete data, SPO2 measurements were excluded from the analysis. Additionally, the SRP group at T3 and the LBP group at T2 and T3 were not included in the analysis.In the SRP group, at T1, the BE group showed significantly better recovery in FEV1 and FVC compared to the control group. By T2, the BE group had a significantly improved sleep quality compared to the control group (P < 0.05). In the LBP group, at T1, the BE group demonstrated a significant advantage in alleviating anxiety symptoms compared to the control group (P < 0.05). No significant differences were observed in other outcomes.

Empowering Recovery: A Co-Designed Intervention to Transform Care for Operable Lung Cancer

BACKGROUND

Patients undergoing surgery for lung cancer experience significant symptom burden and physical impairments. Exercise rehabilitation programmes have been shown to improve symptoms and aid recovery, however, implementation into routine practice has proven challenging.

OBJECTIVE

To develop a robust understanding of the key design requirements of an exercise-based pre- and post-operative rehabilitation prototype intervention designed to support patients with operable lung cancer prepare for and recover from thoracic surgery, and co-design an acceptable intervention prototype with key stakeholders.

DESIGN, SETTING AND PARTICIPANTS

An experience-based co-design (EBCD) study involving patients, caregivers, clinicians, consumer advocates and researchers from across Australia. Two rounds of EBCD workshops were held between November 2023 and May 2024. Workshops were underpinned by the COM-B Model and Theoretical Domains Framework. Qualitative data were thematically analysed by two independent researchers. Identified barriers and facilitators were mapped to the Behaviour Change Wheel, and used to develop the final intervention prototype, which was presented using the Template for Intervention Description and Replication (TIDieR) guide.

RESULTS

Eleven patients (55% female, mean age 66.4 (±9.3) years), one caregiver, and 16 professionals (physiotherapists, nurses, respiratory physicians, a thoracic surgeon, consumer advocates and researchers) participated. Retention between workshop rounds was high (86%). Nineteen major themes were developed, including unmet education needs; the link between mental health and recovery; and the influence of unexpected, persistent symptoms and functional decline. Core intervention principles included flexibility, individualisation and continuity. Essential components included screening/assessment, education, exercise, behaviour change, and mental health support. The intervention prototype was refined in the second workshop round.

CONCLUSIONS

This EBCD study successfully identified key experiences and barriers in preparing for and recovering from lung cancer surgery and engaged stakeholders in complex intervention design, culminating in the development of a flexible, multi-modal pre- and post-operative rehabilitation programme prototype. Future projects will evaluate the prototype acceptability and feasibility.

PATIENT OR PUBLIC CONTRIBUTION

Past patients and their caregivers with lived experience of undergoing/caring for someone undergoing lung cancer surgery, and multidisciplinary professionals, participated in co-design workshops to develop and refine the exercise-based rehabilitation intervention goals, priorities, and prototype.

Care needs and cancer-related post traumatic stress (CR-PTS) in patients with early-stage lung cancer three months after surgery

PURPOSE

Lung cancer is one of the life-threatening diseases. The purposes of this study were to explore (1) the levels of unmet care needs, cancer-related post-traumatic stress (CR-PTS), and symptoms, and (2) factors related to unmet care needs in newly diagnosed early-stage lung cancer (LC) patients three months after surgery.

METHODS

A cross-sectional study with consecutive sampling was conducted in the thoracic outpatient clinic of a medical centre in Taiwan to recruit early-stage (I-IIIA) LC patients. Patients were assessed of their care needs (Supportive Care Needs Survey Screening Tool [SCNS-ST9]), CR-PTS (Impact of Events Scale Revised [IES-R], including intrusion, avoidance, hyperarousal subscales), symptom severity, and background information.

RESULTS

Of the 130 participants enrolled in this study, 62.3% of subjects reported to have overall unmet care needs and 28.5% were at risk of CR-PTS. The levels of unmet care needs are generally in moderate level, with health system and information needs being the highest. Mild to moderate CR-PTS levels were noted, with avoidance, intrusion, and hyperarousal in descending order. Logistic regression identified lower education, higher symptom severity, and higher CR-PTS as the most robust factors related to unmet care needs.

CONCLUSION

The findings of this study highlight the importance of assessing care needs and psychological distress status of patients with early-stage LC. Developing appropriate interventions for this vulnerable patient population and examining their effects on improving care needs and psychological health are urgently needed.

Efficacy of a smartphone application assisting home-based rehabilitation and symptom management for patients with lung cancer undergoing video-assisted thoracoscopic lobectomy: a prospective, single-blinded, randomised control trial (POPPER study)

BACKGROUND

Video-assisted thoracoscopic (VATS) lobectomy can affect patients' pulmonary function and quality of life significantly. No optimal protocol combining patient-reported outcome-based symptom management and postdischarge rehabilitation programme has yet been established. This study aimed to assess the efficacy of a novel smartphone app designed for home-based symptom management and rehabilitation.

METHODS

The app was developed based on three modules: a symptom reporting system with alerts, aerobic and respiratory training exercises, and educational material. Four core symptoms were selected based on a questionnaire survey of 201 patients and three rounds of Delphi voting by 30 experts. The authors screened 265 patients and randomly assigned 136 equally to the app group and usual care group. The primary outcome was pulmonary function recovery at 30 days postoperatively. Secondary outcomes included symptom burden and interference with daily living (both rated using the MD Anderson Symptom Inventory for Lung Cancer), aerobic exercise intensity, emergency department visits, app-related safety, and satisfaction with the app.

FINDINGS

Of the 136 participants, 56.6% were women and their mean age was 61 years. The pulmonary function recovery ratio 1 month after surgery in the app group was significantly higher than that in the usual care group (79.32 vs. 75.73%; P =0.040). The app group also recorded significantly lower symptom burden and interference with daily living scores and higher aerobic exercise intensity after surgery than the usual care group. Thirty-two alerts were triggered in the app group. The highest pulmonary function recovery ratio and aerobic exercise intensity were recorded in those patients who triggered alerts in both groups.

INTERPRETATION

Using a smartphone app is an effective approach to accelerate home-based rehabilitation after VATS lobectomy. The symptom alert mechanism of this app could optimise recovery outcomes, possibly driven by patients' increased self-awareness.

Changes in the Glittre-ADL test in patients with non-small cell lung cancer: Pre- and postoperative analysis after home-based rehabilitation: A preliminary study

Background and objective

Postoperative pulmonary rehabilitation in non-small cell lung cancer (NSCLC) patients following thoracic surgery can be an important strategy for restoring functional exercise capacity. This study aimed to evaluate the changes in the Glittre-ADL test (TGlittre) in patients with NSCLC undergoing thoracic surgery and early home-based pulmonary rehabilitation and, subsequently, to assess the associations of the test results with muscle strength and quality of life (QoL).

Methods

This observational study evaluated 18 patients with NSCLC before and after home-based pulmonary rehabilitation. Before thoracic surgery and 3 months after pulmonary rehabilitation, the participants underwent the following assessments: St. George's Respiratory Questionnaire (SGRQ), spirometry, measurement of the diffusion capacity of the lung for carbon monoxide (DLCO), respiratory muscle strength, handgrip strength (HGS), quadriceps muscle strength, and TGlittre.

Results

When comparing the preoperative and postpulmonary rehabilitation periods, there was a significant increase in HGS [21.6 (19-29) vs. 28.5 (26-33) kgf, p = 0.011] with preservation of TGlittre time [3.6 (3.2-4) vs. 3.6 (3-4.1) min, p = 0.87]. In addition, there was a significant decrease in lung function and SGRQ scores. Preoperative TGlittre time significantly correlated with maximum inspiratory pressure (MIP, r s  = -0.491, p = 0.038) and DLCO (r s  = -0.621, p = 0.006). TGlittre time measured in postpulmonary rehabilitation was significantly correlated with HGS (r s  = -0.664, p = 0.002) and the MIP (r s  = -0.478, p = 0.045).

Conclusion

In patients with NSCLC undergoing thoracic surgery and pulmonary rehabilitation, there was an increase in muscle strength and preservation of functional exercise capacity, although there was a decrease in lung function and QoL. There were interrelations of TGlittre time with MIP and pulmonary diffusion in the preoperative period and of TGlittre time with HGS and MIP following the home-based pulmonary rehabilitation. Although the results are promising, additional studies with a larger number of patients and a control group are needed to further support these findings.

A Qualitative Study of Electronic Patient-Reported Outcome Symptom Monitoring After Thoracic Surgery

INTRODUCTION

Thoracic surgery is a mainstay of therapy for lung cancer and other chronic pulmonary conditions, but recovery is often complicated. Digital health systems can facilitate remote postoperative symptom management yet obstacles persist in their routine clinical adoption. This study aimed to identify patient-perceived barriers and facilitators to using an electronic patient-reported outcome (ePRO) monitoring platform specially designed to detect complications from thoracic surgery postdischarge.

METHODS

Patients (n = 16) who underwent thoracic surgery and participated in an ePRO parent study completed semistructured interviews, which were analyzed using thematic content analysis and iterative team-based coding. Themes were mapped onto the three domains of the Capability, Opportunity, and Motivation Model of behavior framework to inform ePRO design and implementation improvements.

RESULTS

Analysis demonstrated seven dominant themes, including barriers (1. postoperative patient physical and mental health, 2. lack of access to email and poor internet connectivity, 3. lack of clarity on ePRO use in routine clinical care, and 4. symptom item redundancy) as well as facilitators (5. ease of the ePRO assessment completion, 6. engagement with the surgical care team on ePRO use, and 7. increased awareness of symptom experience through ePRO use). Suggested ePRO improvements included offering alternatives to web-based completion, tailoring symptom assessments to individual patients, and the need for patient education on ePROs for perioperative care.

CONCLUSIONS

Addressable barriers and facilitators to implementation of ePRO symptom monitoring in the thoracic surgical patient population postdischarge have been identified. Future work will test the impact of design improvements on implementation outcomes of feasibility and acceptability.

Patient-reported outcomes in lung cancer surgery: A narrative review

Lung cancer is a leading cause of cancer-related mortality worldwide, profoundly affecting patients' quality of life. Patient-reported outcomes (PROs) provide essential insights from the patients' perspective, a crucial aspect often overlooked by traditional clinical outcomes. This review synthesizes research on the role of PROs in lung cancer surgery to enhance patient care and outcomes. We conducted a comprehensive literature search across PubMed, Scopus, and Web of Science up to March 2024, using terms such as "lung cancer," "Patient Reported Outcome," "lobectomy," "segmentectomy," and "lung surgery." The criteria included original studies on lung cancer patients who underwent surgical treatment and reported on PROs. After screening and removing duplicates, reviews, non-English articles, and irrelevant studies, 36 research articles were selected, supported by an additional 53 publications, totaling 89 references. The findings highlight the utility of PROs in assessing post-surgical outcomes, informing clinical decisions, and facilitating patient-centered care. However, challenges in standardization, patient burden, and integration into clinical workflows remain, underscoring the need for further research and methodological refinement. PROs are indispensable for understanding the quality-of-life post-surgery and enhancing communication and decision-making in clinical practice. Their integration into routine care is vital for a holistic approach to lung cancer treatment, promising significant improvements in patient outcomes and quality of care.

Postoperative chronic operation-related symptoms after minimally invasive lung surgery: a prospective observational protocol

INTRODUCTION

Significant numbers of patients undergoing minimally invasive lung surgery develop chronic symptoms such as chronic pain and chronic cough after surgery, which may lead to a reduced quality of life (QoL). Despite this, there remains a dearth of high-quality prospective studies on this topic. Therefore, our study aims to systematically investigate the incidence and progression of long-term chronic symptoms following minimally invasive lung surgery, as well as changes in patient's psychological status and long-term QoL.

METHODS

This is a single-centre, observational, prospective study that included patients with stage I non-small cell lung cancer or benign lesions. Prior to surgery, patients' baseline levels of chronic pain, chronic cough and sleep will be documented. Anxiety, depression and QoL assessments will be conducted using the Hospital Anxiety and Depression Scale (HADS) and the European Organisation for Research and Treatment of Cancer (EORTC) 30-item QoL Questionnaire (QLQ-C30). Following surgery, pain and cough will be evaluated during the initial 3 days using the Numeric Pain Rating Scale and Visual Analogue Scale score, with assessments performed thrice daily. Additionally, sleep status will be recorded daily during this period. Subsequently, postoperative chronic symptoms and QoL will be assessed at weeks 1, 2, 4, 12, 26 and 52. Chronic cough will be evaluated using the Leicester Cough Questionnaire, chronic pain will be assessed via the Brief Pain Inventory and McGill Pain Questionnaire while the EORTC QLQ-C30 questionnaire and HADS will provide continuous monitoring of QoL, anxiety and depression statuses. Data will also include the timing of chronic symptom onset, predisposing factors, as well as aggravating and relieving factors.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Ethics Committees of Fujian Medical University Union Hospital. The findings will be disseminated in peer-reviewed publications.

Beyond surgery: Overcoming postoperative depression in cancer patients

Depression is a common occurrence among cancer patients, and it significantly impacts their clinical outcomes and quality of life, with a high incidence during anti-tumor treatment or after surgery. The association between surgery and depression is the result of the interaction of various factors, including physiological, psychological, and social factors, all of which are intertwined and make patients susceptible to depression after surgical treatment. Postoperative depression has a significant negative impact on many aspects of cancer patients, and it requires timely identification and intervention to improve the overall outcome.

Exploring Central and Bridge Symptoms in Patients with Lung Cancer: A Network Analysis

OBJECTIVES

This study aimed to identify symptom clusters in lung cancer patients undergoing chemotherapy and the central and bridge symptoms within each symptom cluster.

METHODS

In this cross-sectional study, 1,255 patients with lung cancer were recruited through convenience sampling at Nanfang Hospital. Patient symptom burden was assessed using the M.D. Anderson Symptom Inventory (MDASI) and the Lung Cancer module of the MDASI (MDASI-LC). Symptom clusters were identified using the Walktrap algorithm, and central and bridge symptoms in the symptom clusters were identified by network analysis.

RESULTS

The patients included 818 (65.18%) males and 437 (34.82%) females with a mean age of 56.56 ± 11.78 years. Four symptom clusters were identified: fatigue, gastrointestinal, psychoneurological and respiratory. Their central symptoms were fatigue, vomiting, distress and hemoptysis, respectively, and their bridge symptoms were pain, vomiting, dry mouth and shortness of breath.

CONCLUSIONS

Lung cancer symptoms show certain strong correlations with each other, resulting in symptom clusters. Central symptoms may influence other symptoms within a symptom cluster, and bridge symptoms might impact the density of the symptom network. This study identified central and bridge symptoms in lung cancer patients undergoing chemotherapy. Targeting these symptoms with interventions for symptom clusters could make symptom management more precise and effective.

IMPLICATIONS FOR NURSING PRACTICE

In clinical settings, the burden of symptom clusters may be reduced by intervening against the central symptoms of these symptom clusters. Alternatively, if the objective is to diminish the connections between different symptom clusters and holistically alleviate the overall burden, interventions focused on bridge symptoms may be employed.

Lung cancer-specific symptoms and fear of cancer recurrence among recurrence-free non-small cell lung cancer survivors

PURPOSE

Lung cancer survivors have more psychosocial problems, including depression and anxiety disorder, than other cancer survivors. Lung cancer-specific symptoms, such as cough, dyspnea, or pain in chest, might increase FCR among survivors. We aimed to evaluate the association between lung cancer-specific symptoms and FCR among recurrence-free non-small cell lung cancer (NSCLC) survivors.

METHODS

This is a cross-sectional study. Recurrence-free NSCLC survivors were recruited from January to October 2020 at a tertiary hospital in Seoul, Korea. We measured FCR using the Korean version of FCRI-SF and categorized them into three groups: non-clinical FCR (nFCR, < 13), subclinical FCR (sFCR, 13 to 21), and clinical FCR (cFCR, ≥ 22). Lung cancer-specific symptoms were measured using the Korean version of EORTC QLQ-LC13 and EORTC QLQ-C30.

RESULTS

A total of 727 survivors were enrolled. One-third (30.8%) of survivors reported sFCR, and 19.7% had cFCR. In a multivariate analysis, survivors with severe pain in chest were 4.7 times (95% CI: 2.4-9.0) more likely to experience cFCR compared to those without it. Mild dyspnea (OR 1.7, 95% CI: 1.1-2.7) and mild dysphagia (OR 2.4, 95% CI: 1.3-4.4) were associated with cFCR. Survivors with sFCR (Coef. - 6.3, 95% CI: - 9.8, - 2.8) and cFCR (Coef. - 11.3, 95% CI: - 15.5, - 7.2) had poorer quality of life compared to survivors with nFCR.

CONCLUSION

NSCLC survivors were experiencing lung cancer-specific symptoms even a few years after treatment, which were associated with cFCR, resulting in poor HRQoL. It is necessary to develop a lung cancer-specific symptom checklist and use it during even long-term surveillance.

"It's Incapacitated Me in so Many Ways": Older Adults' Lived Experience With Postoperative Symptoms at Home After Major Elective Surgery

OBJECTIVE

This qualitative study aimed to explore the challenges faced by older adults regarding the postoperative symptom experience after major elective surgery.

BACKGROUND

Although extensively studied in oncology settings, the impact of postoperative symptom burden remains largely underexplored in elective major surgery among older adults.

METHODS

We employed convenience sampling to recruit adults aged 65 years or above undergoing major elective surgery at the University of California, San Francisco. Semistructured interviews regarding the surgical experience were conducted at 1 and 3 months postoperatively. An inductive qualitative approach was used to identify emerging themes. Symptoms revealed by participants during interviews were also captured.

RESULTS

Nineteen participants completed a 1-month postoperative interview, and 17 additionally completed a 3-month interview. Three themes emerged: (1) postoperative symptoms significantly impacted valued life activities and psychosocial well-being, (2) participants felt "caught off guard" by the intensity and duration of postoperative symptoms, and (3) participants expressed the need for additional support, resources, and education on symptom management. The most frequently mentioned symptoms were postoperative pain (n=12, 63.1%), gastrointestinal discomfort (n=8, 42.1%), and anxiety/stress (n=8, 42.1%) at 1-month postsurgery compared with pain and depression (both n=6, 35.3%) at 3 months.

CONCLUSIONS

Study participants were surprised by the negative impact of postoperative symptoms on their psychosocial well-being and ability to engage in valued life activities. Symptom burden is an important patient-reported outcome that should be assessed postoperatively. Interventions to minimize postoperative symptom burden in older adults could optimize quality of life and participation in meaningful activities during surgical recovery.

Network evolution of core symptoms after lung cancer thoracoscopic surgery:A dynamic network analysis

OBJECTIVES

To investigate relationships between various symptoms occurring 1-2 and 5-6 days following days after thoracoscopic surgery, to identify core symptoms, and to monitor changes in core symptoms over time following lung cancer thoracoscopic surgery.

METHODS

We evaluated symptoms using the Anderson Symptom Scale (Chinese version) and the Lung Cancer-Specific Symptoms Template in 214 lung cancer patients hospitalized in the Department of Thoracic Surgery of a provincial hospital in Jiangsu Province from March 2023 to September 2023. Data was collected at 1-2 days and 5-6 days postoperatively. Symptom networks were constructed for each time point, and centrality indicators were analyzed to identify core symptoms while controlling for influencing factors.

RESULTS

According to the network analysis, fatigue (rs = 26.00、rc = 0.05、rb = 1.02) had the highest strength, closeness, and betweenness in the symptom network 1-2 days after lung cancer surgery. At 5-6 days after surgery, shortness of breath (rs = 27.00) emerged as the symptom with the highest strength, fatigue (rc = 0.04) had the highest closeness, and cough (rb = 1.08) ranked highest in betweenness within the symptom network.

CONCLUSION

Fatigue stands out as the most core symptom in the network 1-2 days after lung cancer surgery. Shortness of breath, fatigue and cough are the most core symptoms in the symptom network 5-6 days after surgery. Therefore, clinical staff can improve the postoperative symptom experience of lung cancer patients by developing symptom management programmes tailored to these core symptoms.

Relationship between changes in pulmonary function and patient-reported outcomes of lung cancer surgery

PURPOSE

To investigate the relationship between changes in pulmonary function (PF) and patient-reported outcomes (PROs) of lung cancer surgery.

METHODS

We recruited 262 patients who underwent lung resection for lung cancer, to evaluate the PROs, using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-C30 and the Lung Cancer 13-question supplement (LC13). The patients underwent PF tests and PRO assessments preoperatively (Pre) and 1 year after surgery (Y1). Changes were calculated by subtracting the value at Pre from the value at Y1. We set two cohorts: patients under the ongoing protocol (Cohort 1) and patients who were eligible for lobectomy with clinical stage I lung cancer (Cohort 2).

RESULTS

Cohorts 1 and 2 comprised 206 and 149 patients, respectively. In addition to dyspnea, changes in PF were also correlated with scores for global health status, physical and role function scores, fatigue, nausea and vomiting, pain, and financial difficulties. Absolute correlation coefficient values ranged from 0.149 to 0.311. Improvement of emotional and social function scores was independent of PF. Sublobar resection preserved PF more than lobectomy did. Wedge resection mitigated dyspnea in both cohorts.

CONCLUSION

The correlation between PF and PROs was found to be weak; therefore, further studies are needed to improve the patient's postoperative experience.

Effect of Preoperative Home-Based Exercise Training on Quality of Life After Lung Cancer Surgery: A Multicenter Randomized Controlled Trial

BACKGROUND

Preoperative exercise training is recommended for improvement of clinical outcomes after lung cancer (LC) surgery. However, its effectiveness in preventing postoperative decline in quality of life (QoL) remains unknown. This study investigated the effect of preoperative home-based exercise training (PHET) on QoL after LC surgery.

METHODS

Patients awaiting LC resection were randomized to PHET or a control group (CG). The PHET program combined aerobic and resistance exercise, with weekly telephone supervision. Primary outcome was QoL-assessed with the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) at baseline, before surgery, and 1 month after surgery. The secondary outcomes were hospital length of stay and physical performance. The main analysis included a factorial repeated-measures analysis of variance. Additionally, the proportion of patients experiencing clinical deterioration from baseline to post-surgery was assessed.

RESULTS

The study included 41 patients (68.1 ± 9.3 years; 68.3% male) in the intention-to-treat analysis (20 PHET patients, 21 CG patients). A significant group × time interaction was observed for global QoL (p = 0.004). Between-group differences in global QoL were statistically and clinically significant before surgery (mean difference [MD], 13.5 points; 95% confidence interval [CI], 2.4-24.6; p = 0.019) and after surgery (MD, 12.4 points; 95% CI, 1.3-23.4; p = 0.029), favoring PHET. Clinical deterioration of global QoL was reported by 71.4% of the CG patients compared with 30 % of the PHET patients (p = 0.003). Between-group differences in favor of PHET were found in pain and appetite loss as well as in physical, emotional and role functions after surgery (p < 0.05). Compared with CG, PHET was superior in improving preoperative five-times sit-to-stand and postoperative exercise capacity (p < 0.05). No between-group differences in other secondary outcomes were observed.

CONCLUSION

The study showed that PHET can effectively prevent the decline in QoL after LC surgery.

The unmet needs of patients in the early rehabilitation stage after lung cancer surgery: a qualitative study based on Maslow's hierarchy of needs theory

PURPOSE

This study aimed to explore the unmet needs of lung cancer patients in early rehabilitation, based on Maslow's hierarchy of needs theory.

METHODS

Information on the experiences of 20 patients was collected through semi-structured interviews. The interviews were conducted in the surgical nursing clinic within 1 week of discharge from hospital. The data were analysed using a combination of deductive (theory-driven) and inductive (data-driven) methods, using Maslow's Hierarchy of Needs as a framework for identifying and organising themes.

RESULTS

Patients had a mean age of 50.92 years (SD 11.88); n = 11 (55%) were female. Major themes aligned with the dimensions of Maslow's hierarchy of needs model. Five major themes with 12 corresponding sub-themes emerged: (1) physiological needs, including "self-care and independence in life", "return to pre-operative status as soon as possible", "increase exercise under specialist guidance" and "reduce cough and pain and improve sleep quality"; (2) safety and security needs, such as "symptom management", "regulation of the emotions of worry and fear" and "access accurate treatment information"; (3) love and belonging needs, including "accompany family members" and "chat with friends";(4)Esteem needs: "live with dignity";(5) Self-actualization, such as "accept and submit to the reality of cancer" and "live meaningfully".

CONCLUSIONS

The findings of this study indicated that there were many unmet needs for patients during the early recovery period after lung cancer surgery. An overview of the different areas of need identified in this study may guide future research and development of interventions to improve patients' quality of life during the home rehabilitation phase.

Altered functional connectivity of the nucleus tractus solitarii in patients with chronic cough after lung surgery: an rs-fMRI study

BACKGROUND

To explore the altered functional connectivity (FC) of the nucleus tractus solitarii (NTS) in patients with chronic cough after lung surgery using resting-state functional magnetic resonance imaging (rs-fMRI), and the association between abnormal FC and clinical scale scores.

METHODS

A total of 22 patients with chronic cough after lung surgery and 22 healthy controls were included. Visual analog scale (VAS), Mandarin Chinese version of the Leicester Cough Questionnaire (LCQ-MC), and Hamilton anxiety rating scale (HAMA) scores were assessed, and rs-fMRI data were collected. The FC analysis was performed using the NTS as the seed point, and FC values with all voxels in the whole brain were calculated. A two-sample t-test was used to compare FC differences between the two groups. The FC values of brain regions with differences were extracted and correlated with clinical scale scores.

RESULTS

In comparison to healthy controls, FC values in the NTS and anterior cingulate cortex(ACC) were reduced in patients with chronic cough after lung surgery (GRF correction, p-voxel < 0.005, p-cluster < 0.05) which were positively correlated with LCQ-MC scores (r = 0.534, p = 0.011), but with VAS (r = -0.500, p = 0.018), HAMA (r = -0.713, p < 0.001) scores were negatively correlated.

CONCLUSIONS

Reduced FC of the NTS with ACC may be associated with cough hypersensitivity and may contribute to anxiety in patients with chronic cough after lung surgery.

Recall Bias in the Assessment of Cough for Patients Discharged from Lung Surgery

Purpose

This study aimed to evaluate the presence of recall bias when patients retrospectively report cough scores.

Patients and Methods

Patients who underwent lung surgery between July 2021 and November 2021 were recruited for this study. We retrospectively assessed the severity of cough within the past 24 hours and the past 7 days using a 0-10 numerical rating scale. Recall bias was defined as the difference between the scores reported on the two assessments. Patients were grouped based on the longitudinal change in cough scores from pre-operation to 4 weeks after discharge using group-based trajectory models. Using generalized estimating equation to explore the factors influencing recall bias.

Results

Overall, 199 patients were analyzed and demonstrated the three distinct trajectories of post-discharge cough: high (21.1%), medium (58.3%), and low (20.6%). Significant recall bias was found in week 2 for the high-trajectory patients (6.26 vs 5.10, P<0.01) and in week 3 for the medium-trajectory patients (2.88 vs 2.60, P=0.01). Among all recall bias, 41.8% were of underestimation, and 21.7% of overestimation. The high trajectory group (β=1.14, P<0.01) and measurement interval (β=0.36, P<0.01) were risk factors for underestimation, while post-discharge time (β=-0.57, P<0.01) and measurement interval (β=-0.13, P=0.02) were protective factors for overestimation.

Conclusion

Retrospective assessment of post-discharge cough in patients who underwent lung surgery will introduce recall bias, with a tendency of underestimation. The high-trajectory group, interval time and post-discharge time are influencing factors of recall bias. For patients with severe cough at discharge, a shorter recall periods should be employed for monitoring, due to the large bias that results from a longer recall period.

Anxiety, depression, and quality of life in postoperative non-small cell lung cancer patients under the intervention of cognitive-behavioral stress management

Objective

Cognitive-behavioral stress management (CBSM) is a psychotherapy that helps patients cognize and manage stress to improve mental health and quality of life. This study aimed to explore the influence of CBSM on anxiety, depression, and quality of life in non-small cell lung cancer (NSCLC) patients.

Methods

In total, 172 NSCLC patients who received tumor resection were randomized 1:1 into the usual care (UC) group (N = 86) and CBSM group (N = 86) to receive 10-week UC and CBSM interventions. Moreover, all participants attended a 6-month follow-up.

Results

Hospital Anxiety and Depression Scales (HADS)-anxiety score at 3^rd month (M3) (P = 0.015) and 6^th month (M6) (P = 0.018), HADS-depression score at M3 (P = 0.040) and M6 (P = 0.028), and depression rate at M6 (P = 0.035) were descended in CBSM group compared to UC group. Besides, depression severity was reduced at M6 (P = 0.041) in CBSM group compared to UC group, but anxiety severity only showed a decreased trend (P = 0.051). Additionally, Quality of Life Questionnaire-Core 30 (QLQ-C30) global health status score and QLQ-C30 function score at 1^st month (M1), M3, and M6 were elevated (all P < 0.05), while QLQ-C30 symptoms score was declined at M1 (P = 0.031) and M3 (P = 0.014) in CBSM group compared to UC group. Notably, the efficacy of CBSM was impressive in patients with baseline depression or undergoing adjuvant therapy.

Conclusion

CBSM is a feasible intervention that effectively improves mental health and quality of life in postoperative NSCLC patients.
