Long-term patient-reported outcomes after non-small cell lung cancer resection

Stress-induced eosinophil activation contributes to postoperative morbidity and mortality after lung resection

Respiratory failure occurs more frequently after thoracic surgery than abdominal surgery. Although the etiology for this complication is frequently attributed to underlying lung disease present in patients undergoing thoracic surgery, this notion is often unfounded because many patients with normal preoperative pulmonary function often require prolonged oxygen supplementation even after minimal resection of lung tissue. Using a murine model of pulmonary resection and peripheral blood samples from patients undergoing resection of the lung or abdominal organs, we demonstrated that lung surgery initiates a proinflammatory loop that results in damage to the remaining lung tissue, noncardiogenic pulmonary edema, hypoxia, and even death. Specifically, we demonstrated that resection of murine lung tissue increased concentrations of the homeostatic cytokine interleukin-7, which led to local and systemic activation of type 2 innate lymphoid cells. This process activated lung-resident eosinophils and facilitated stress-induced eosinophil maturation in the bone marrow in a granulocyte-macrophage colony-stimulating factor-dependent manner, resulting in systemic eosinophilia in both mice and humans. Up-regulation of inducible nitric oxide synthase in lung-resident eosinophils led to tissue nitrosylation, pulmonary edema, hypoxia, and, at times, death. Disrupting this activation cascade at any stage ameliorated deleterious outcomes and improved survival after lung resection in the mouse model. Our data suggest that repurposing US Food and Drug Administration-approved eosinophil-targeting strategies may potentially offer a therapeutic intervention to improve outcomes for patients who require lung resection for benign or malignant etiology.

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.

Patient motivators of postoperative electronic patient-reported outcome symptom monitoring use in thoracic surgery patients: a qualitative study

BACKGROUND

Electronic patient-reported outcome (ePRO) systems can be used to engage patients in remote symptom monitoring to support postoperative care. We interviewed thoracic surgery patients with ePRO experience to identify factors that influenced use of ePROs to report their symptoms post-discharge.

METHOD

This qualitative study used semi-structured telephone interviews with adults who underwent major thoracic surgery at an academic medical center in North Carolina. Individuals who enrolled in symptom monitoring, completed at least one ePRO survey, and were reachable by phone for the interview were included. The ePRO surveys assessed 10 symptoms, including validated Patient-Reported Outcome Common Terminology Criteria for Adverse Events (PRO-CTCAE) measures and thoracic surgery-specific questions. Surveys, offered via web-based and automated telephone options, were administered for four weeks post-discharge with alerts sent to clinicians for concerning symptoms. The interviews were guided by the Capability, Opportunity, Motivation model for behavior change (COM-B) and examined factors that influenced patients' completion of ePRO surveys post-discharge. Team members independently coded interviews and identified themes, informed by COM-B. We report descriptive statistics (demographics, number of surveys completed) and themes organized by COM-B components.

RESULTS

Of 28 patients invited, 25 (89%) completed interviews from July to October 2022. Participants were a median 58 years, 56% female, 80% White, and 56% had a history of malignancy. They completed 131/150 (87%) possible ePRO surveys. For capability, participants reported building ePROs into their routine and having the skills and knowledge, but lacking physical and emotional energy, to complete ePROs. For opportunity, participants identified the ease and convenience of accessing ePROs and providers' validation of ePROs. Motivators were perceived benefits of a deepening connection to their clinical team, improved symptom management for themselves and others, and self-reflection about their recovery. Factors limiting motivation included lack of clarity about the purpose of ePROs and a disconnect between symptom items and individual recovery experience.

CONCLUSIONS

Patients described being motivated to complete ePROs when reinforced by clinicians and considered ePROs as valuable to their post-discharge experience. Future work should enhance ePRO patient education, improve provider alerts and communications about ePROs, and integrate options to capture patients' complex health journeys.

Advances in the clinical use of patient-reported outcomes in thoracic surgery

PURPOSE OF REVIEW

Patient-reported outcomes (PROs) are increasingly recognized as a clinical tool for measuring and improving patient-centric care. This review provides a summary on recent advances in the use of PROs in the field of thoracic surgery.

RECENT FINDINGS

PROs have been used as primary endpoints in clinical trials and observational studies evaluating clinical care pathways and quantifying the benefits of minimally invasive surgical techniques for patients undergoing lung surgery. Qualitative and quantitative research has yielded fundamental insights into which PRO domains are meaningful and valued by patients after lung surgery. Patient experience and recovery after esophagectomy have been further characterized by using PROs. New disease-specific survey tools for patients have been developed to track long-term symptoms after esophageal reconstruction. Patient satisfaction has emerged as the key metric used to gauge the patient centeredness of hospital systems.

SUMMARY

Advances have been made in the application of PROs in multiple areas of thoracic surgery, which include lung and esophageal surgery. The growing focus on the use of PROs in clinical pathways has led to a better understanding on how to optimize patient experience.

Timing of recovery of quality of life after robotic anatomic lung resection

Patient-reported outcomes (PROs) are an underreported aspect of surgical recovery. The purpose of our study was to track PROs after robotic anatomic lung to determine the timing to recovery of baseline patient baseline quality of life. This was a prospective cohort study at an academic medical center (4/2021-12/2022). Patients who underwent robotic anatomic lung resection were asked to complete PROMIS-29 surveys at the preoperative clinic visit, postoperative clinic visit, 30 days and 90 days postoperatively via in-person and email-based electronic surveys. The PROPr score, a summary of health-related quality of life, and mental and physical health z-scores were estimated for each patient using published methods and compared by postoperative timing. 75 patients completed the preoperative survey and at least one postoperative survey; 56 completed postoperative clinic surveys, 54 completed 30-day postoperative surveys, and 40 completed 90-day postoperative surveys. All three PROMIS scores decreased between the preoperative and first postoperative visit (all p < 0.05). PROPr scores increased over time but remained significantly worse than baseline by 90 days (-0.08 difference between 90 days and preoperative, p = 0.02). While PROMIS summary z-scores for physical health remained - 0.29 lower at 90 days postoperatively, this did not reach statistical significance (p = 0.06). Mental health scores returned to baseline by 90 days postoperatively (p = 0.41). While some PROs returned to baseline by 90 days postoperatively, overall quality-of-life scores remained significantly below preoperative baselines. These findings are important to share with patients during the informed consent process to achieve patient centered care more effectively.

A Visual Analysis of Patient-Reported Outcomes in Lung Cancer From 2013 to 2023

BACKGROUND

Lung cancer is the most common cancer in the world and has become one of the malignancies with the highest incidence and mortality; more than half of patients die within one year of being diagnosed with lung cancer. In recent years, the concept of "patient-centered" service has gained popularity, and patients' subjective feelings have gradually been used in clinical decision-making. Therefore, this study determined the application of visual patient report outcomes in the field of lung cancer, in order to provide reference for specific clinical practice.

METHODS

Using the Web of Science core collection as the main analysis content, Citespace and VOSviewer were used to conduct this scientometric study.

RESULTS

A total of 499 literatures that met the inclusion criteria were retrieved. The most prolific institution was The University of Texas MD Anderson Cancer Center, and the United States dominates this field.

CONCLUSION

The measurement of patient-reported outcomes is considered the gold standard for effectively evaluating patients' perceptions of clinical interventions or diseases. It is recommended that patient-reported outcomes be integrated into routine care for cancer patients in order to enhance communication between patients and healthcare providers.

Relevance of pleural adhesions for short- and long-term outcomes after lung volume reduction surgery

Objective

Pleural adhesions (PLAs) have been shown to be a possible risk factor for air leak after lung volume reduction surgery (LVRS), but the relevance of PLA for lung function outcome remains unclear. We analyzed our LVRS cohort for the influence of PLA on short-term (ie, prolonged air leak) and long-term outcomes.

Methods

Retrospective observational cohort study with 187 consecutive patients who underwent LVRS from January 2016 to December 2019. PLA were defined as relevant if they were distributed extensively at the dorsal pleura; were present in at least at 2 areas, including the dorsal pleura; or present extensively at the mediastinal pleura. In patients with bilateral emphysema, bilateral LVRS was performed preferentially. The objectives were to quantify the association of PLA and rate of prolonged air leak (chest tube >7 days), and the association of PLA with postoperative exacerbations and with forced expiratory volume in 1 second 3 months postoperatively. The associations were quantified with odds ratios for binary outcomes, and with between-group differences for continuous outcomes. To account for missing observations, 100-fold multiple imputation was used.

Results

PLAs were found in 46 of 187 patients (24.6%). There was a 32.6% rate of prolonged air leak (n = 61), mean chest tube time was 7.84 days. A total of 94 (50.3%) LVRSs were unilateral and 93 were bilateral. There was evidence for an association between PLA and the rate of prolonged air leak (odds ratio, 2.83; 95% CI, 1.36 to 5.89; P = .006). There was no evidence for an association between PLA and postoperative exacerbations (odds ratio, 1.11; 95% CI, 0.5 to 2.45; P = .79). There was no evidence for an association between PLA and forced expiratory volume in 1 second (estimate -1.52; 95% CI -5.67 to 2.63; P = .47). Both unilateral and bilateral LVRS showed significant postoperative improvements in forced expiratory volume in 1 second by 27% (8.43 units; 95% CI, 3.66-13.12; P = .0006) and by 28% (7.87 units; 95% CI, 4.68-11.06; P < .0001) and a reduction in residual volume of 15% (-33.9 units; 95% CI, -56.37 to -11.42; P = .003) and 15% (-34.9 units; 95% CI, -52.57 to -17.22; P = .0001), respectively.

Conclusions

Patients should be aware of potential prolongation of hospitalization due to PLA. However, there might be no relevant influence of PLA on lung function outcomes.

Prospective, Multi-Institutional Observational Study of Deterioration in Activities of Daily Living in Elderly Patients After Lung Cancer Surgery

Introduction

To determine the rate of deteriorating activities of daily living (ADL) and to investigate predictive factors in elderly patients undergoing surgery for NSCLC.

Methods

Patients with NSCLC aged 75 years or older who underwent curative surgical resection were evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence Instrumental ADL (TMIG-IADL) and the Japanese version of EuroQol 5-dimensions 5-level (EQ-5D-5L) quality-of-life scale administered at baseline and at 6 months postoperative. The primary end point was the rate of living patients without substantial deterioration of TMIG-IADL, defined as a decline greater than or equal to three points. Multivariable logistic regression was performed to determine risk factors for deteriorating ADL.

Results

Between May 2019 and May 2020, 876 of the 986 screened patients enrolled from 47 institutions were eligible and included in the analysis. TMIG-IADL and EQ-5D-5L scores were obtained from 96.0% and 92.6% of the patients, respectively. At 6 months postoperative, 745 patients (85.1%, 95% confidence interval: 82.5%-87.3%) reported no significant ADL deterioration, and 96 of 841 patients (11.4%) with postoperative score data reported significant deterioration. The social domain was the most frequently affected activity. In multivariable analysis, poor performance status, low G8 geriatric screening score, segmentectomy (versus wedge resection), and surgery lasting less than 3 hours were associated with deteriorating ADL. Worsening EQ-5D-5L scores by minimally important difference or more were observed in 22.1% of the patients. Changes in TMIG-IADL and EQ-5D-5L scores were poorly correlated.

Conclusions

Approximately 15% of elderly patients with NSCLC experienced significant ADL deterioration at 6 months postoperative.
