OBJECTIVE: The objective of this systematic review was to explore the evidence regarding shared decision-making (SDM) in the management of pulmonary nodules.
METHODS: Systematic review of quantitative and qualitative studies.
METHODS: Studies published in English or Chinese up to April 2022 were extracted from nine databases: PubMed, PsycINFO, EMBASE, Cochrane Library, Web of Science and CINAHL, China National Knowledge Infrastructure, Wanfang Data and SinoMed Data.
METHODS: Studies were eligible if patients or healthcare providers are faced with pulmonary nodule management options or the interventions or experiences were focused on the patient-healthcare provider relationship or health education to make, increase or support shared decisions. All types of studies were included, including quantitative and qualitative studies. Grey literature and literature that had not been peer reviewed were excluded. Poster abstracts and non-empirical publications such as editorials, letters, opinion papers and review articles were excluded.
METHODS: Two reviewers independently screened abstracts and full texts, assessed quality using Joanna Briggs Institute\'s critical appraisal tools, and extracted data from included studies. Thematic syntheses were used to identify prominent themes emerging from the data.
RESULTS: A total of 12 studies met the inclusion criteria, 11 of which were conducted in USA. These included six qualitative studies and six quantitative studies (including both survey and quasi-experimental designs). Three major themes with specific subthemes emerged: (1) Opportunity (uncertainty in the diagnosis and treatment of pulmonary nodules, willingness to participate in decision-making); (2) Ability (patient\'s lack of knowledge, physician\'s experience); and (3) Different worldview (misconception, distress among patients, preference for diagnosis and treatment).
CONCLUSIONS: Uncertainty in the management of pulmonary nodules is the opportunity to implement SDM. Patients\' lack of knowledge, distress, and misunderstandings between healthcare providers and patients are both the main obstacles and the causes of the application of SDM.

BACKGROUND: Non-small cell lung cancer (NSCLC) has a poor prognosis. Transvascular intervention is an important approach for treating NSCLC. Drug-eluting bead bronchial artery chemoembolisation (DEB-BACE) is a technique of using DEBs loaded with chemotherapeutic drugs for BACE. This study aims to conduct a meta-analysis to comprehensively assess the effectiveness and safety of DEB-BACE in treating NSCLC and investigate a novel therapeutic strategy for NSCLC.
METHODS: Wanfang, China National Knowledge Infrastructure, Medline (via PubMed), Cochrane Library, Scopus and Embase databases will be searched in November 2024. A meta-analysis will be conducted to assess the effectiveness and safety of DEB-BACE in the treatment of NSCLC. The following keywords will be applied: \"Carcinoma, Non-Small-Cell Lung\", \"Non-Small Cell Lung Cancer\", \"Drug-Eluting Bead Bronchial Arterial Chemoembolization\" and \"drug-eluting beads\". Reports in Chinese or English comparing the efficacy of DEB-BACE with other NSCLC treatment options will be included. Case reports, single-arm studies, conference papers, abstracts without full text and reports published in languages other than English and Chinese will not be considered. The Cochrane Handbook for Systematic Reviews of Interventions will be used to independently assess the risk of bias for each included study. In case of significant heterogeneity between studies, possible sources of heterogeneity will be explored through subgroup and sensitivity analysis. For the statistical analysis of the data, RevMan V.5.3 will be used.
BACKGROUND: This meta-analysis will seek publication in a peer-reviewed journal on completion. Ethical approval is not required for this study as it is a database-based study.

OBJECTIVE: The CAPSTONE-1 trial demonstrated that adebrelimab-based immunotherapy yielded a favourable survival benefit compared with chemotherapy for patients with extensive-stage small cell lung cancer (ES-SCLC). This study aims to evaluate the cost-effectiveness of this immunotherapy in the treatment of ES-SCLC from a healthcare system perspective in China.
METHODS: The TreeAge Pro software was used to establish a three-state partitioned survival model. Survival data came from the CAPSTONE-1 trial (NCT03711305), and only direct medical costs were included. Utility values were obtained from the published literature. Sensitivity analysis was performed to explore the robustness of the model. The cost-effectiveness of immunotherapy was investigated through scenario and exploratory analyses in various settings.
METHODS: Total costs, incremental costs, life years, quality-adjusted life-years (QALYs), incremental QALYs and incremental cost-effectiveness ratio (ICER).
RESULTS: The basic analysis revealed that the adebrelimab group achieved a total of 1.1 QALYs at a cost of US$65 385, while the placebo group attained 0.78 QALYs at a cost of US$12 741. ICER was US$163 893/QALY. Sensitivity analysis confirmed that the model was robust. Results from scenario and exploratory analyses indicated that the combination of adebrelimab and chemotherapy did not demonstrate cost-effectiveness in any scenario.
CONCLUSIONS: From the perspective of the Chinese healthcare system, adebrelimab in combination with chemotherapy for the treatment of ES-SCLC was not economical compared with chemotherapy.

The objective of this study was to evaluate the cost-effectiveness of durvalumab in combination with chemotherapy compared with chemotherapy alone as first-line therapy for metastatic non-small-cell lung cancer (NSCLC) from the perspective of the US payer.
Based on the POSEIDON clinical trial, a partition survival model was developed to compare the cost-effectiveness of durvalumab in combination with chemotherapy versus chemotherapy alone for the first-line treatment of metastatic NSCLC. The model\'s primary outcomes were costs, life years (LYs), quality-adjusted LYs (QALYs) and the incremental cost-effectiveness ratio (ICER). The analysis only considered direct medical costs, and health utility value was determined using published literature. The robustness of the model was tested by probabilistic sensitivity analyses.
The combination therapy of durvalumab and chemotherapy improved survival by 0.713 QALYs at an incremental cost of $64 104.638 compared with chemotherapy alone, resulting in an ICER of $89 908.328 per QALY gained from the US payer perspective. The combination therapy had a 92.3% probability of being cost-effective at a willingness-to-pay threshold of $150 000 per QALY based on incremental net health benefits. Sensitivity analyses confirmed the model\'s consistency, and none of the parameters significantly influenced the findings.
Durvalumab in combination with chemotherapy represents a more cost-effective strategy for first-line therapy in patients with metastatic NSCLC in the USA compared with chemotherapy alone.

Lung nodules are one of the most prevalent diseases. Medical imaging methods have a high false positive rate for distinguishing malignant nodules from benign nodules. Therefore, developing new technologies with high accuracy for screening malignant nodules is of great importance for lung nodule surveillance. Use of flow cytometry to detect biomarkers in blood macrophages (epitop detect in macrophages/macrophages) has opened a new era for early and noninvasive diagnosis of cancer. This planned study aims to examine whether the peripheral blood macrophage factors Apo10 and TKTL1 accurately distinguish malignant nodules from benign nodules.
We plan to enrol in this study 3825 participants with lung nodules who will attend their annual physical examination at Sun Yat-sen University Cancer Center. Apo10 and TKTL1 levels in all patients will be tested at 60 min after their last meal every 6 months during their 3-year follow-up. Biopsy or surgical pathology results will be collected as the gold standard to assess the accuracy of Apo10 and TKTL1 in distinguishing malignant nodules from benign nodules. The sensitivity, specificity, positive predictive value, negative predictive value and area under the receiving operating characteristic curve will also be evaluated.
The study is approved by the medical ethics committee of Sun Yat-sen University (SL-G2022-005-02). The results of this study will be disseminated in peer-reviewed publications and presentations at international scientific meetings and will also be disseminated to the participants.

The ASTRUM-005 trial showed that serplulimab plus chemotherapy (SEP) significantly extended survival time compared with chemotherapy in the treatment of small cell lung cancer. But the survival benefits of SEP came at high costs, and its economy is not clear. Therefore, this study aimed to evaluate the cost-effectiveness of SEP from the perspective of the Chinese healthcare system.
A partition survival model was built to simulate the outcomes. The clinical data came from the ASTRUM-005 trial, and only direct medical costs were included in the model. The utility values referred to the published literature. Scenario analyses 1 and 2 explored outcomes in the presence of a patient assistance plan (PAP) and different simulation periods, respectively. Scenario analysis 3 compared the cost-effectiveness of atezolizumab plus chemotherapy (AEP) with SEP by network meta-analysis. Sensitivity analyses were conducted to assess the robustness of the results.
Total costs, incremental costs, life years, quality-adjusted life years (QALYs), incremental QALYs and incremental cost-effectiveness ratio (ICER).
Compared with chemotherapy, SEP achieved an additional 0.34 QALYs at incremental costs of US$41 682.63, with an ICER of US$122 378.86/QALY. When PAP was available, ICER was US$58 316.46/QALY. In the simulation time of 5 years and 20 years, the ICER was US$132 637.97/QALY and US$118 054.59/QALY, respectively. When compared with AEP, SEP not only reduced the costs by US$47 244.87 but also gained 0.07 QALYs more. Sensitivity analyses showed that the price of serplulimab and the utility value of the progression-free survival stage were the main influencing parameters, and the results were stable.
Compared with chemotherapy, SEP was not cost-effective from the perspective of the Chinese healthcare system. However, SEP was absolutely dominant in comparison with AEP.

In December 2018, China launched national volume-based procurement (NVBP) to negotiate drug prices with manufacturers. Gefitinib was one of the 25 pilot drugs, which is used for treatment of non-small cell lung cancer. Lung cancer is the most common type of cancer in China and targeted drugs like gefitinib have been proven to provide clinical benefits to patients. This study aims to explore the impact of NVBP policy on the usage and expenditure of anticancer drugs.
Gefitinib and alternative drugs (icotinib and erlotinib) were used as objects of study. Quarterly data from the China Hospital Pharmaceutical Audit database in 9454 hospitals in China were used for analysis. Descriptive analysis was conducted using purchase volume and expenditure as variables. Interrupted time-series (ITS) analysis was applied to further analyse the effect of NVBP policy on the medicines under study.
During the 12-month period before (2018Q2-2019Q1) and after (2019Q2-2020Q1) the NVBP policy, the total purchase volume of medicines rose from 4.48 million defined daily dose (DDD) to 7.02 million DDD, with an increase of 56.66%. Purchase volume of gefitinib and alternative drugs increased 100.61% and 14.88%, respectively. After the implementation of NVBP policy, procurement volume of alternative drugs decreased by 72 051 DDD (p value=0.044) and trend change decreased by 56 738 DDD (p value<0.01). The overall expenditure reduction was 14.7%, with the expenditure of gefitinib reducing by 38.47% and alternative drugs increasing by 10.70%. ITS analysis indicated statistically significant differences in level and trend changes for expenditure of total drugs and gefitinib.
The evidence provided in this study indicated that the implementation of NVBP policy was related to the expenditure reduction of the first generation of anti-EGFR lung cancer drugs. The policy effectively controlled the increase in expenditures for corresponding drugs while ensuring the use of drugs.

Lung cancer remains a highly fatal disease. Surgical resection has been proven to be the most effective treatment for early-stage lung cancer. The conventional hospital-based pulmonary rehabilitation (PR) is shown to reduce symptoms, improve exercise capacity and impact the quality of life (QoL) for lung cancer patients. To date, scientific evidence on the effectiveness of home-based PR for patients with lung cancer following surgery is scarce. We aim to explore if home-based PR is non-inferior to outpatient PR for patients with lung cancer following surgical resection.
This study is a two-arm, parallel-group, assessor-blind, single-centre, randomised controlled trial. Participants will be recruited from West China Hospital, Sichuan University and randomly allocated to either an outpatient group or a home-based group at a ratio of 1:1. The PR programme involves self-management and exercises. The exercise includes warm-up (10 min), aerobic training (20 min), resistance training (15 min) and cool-down (10 min), lasting 4 weeks, with two sessions per week either at home or in the outpatient setting. The intensity will be adjusted according to the modified Borg rating of perceived exertion and heart rate before and after each exercise session. The primary outcome is QoL measured by EORTC QLQ-C30 & LC 13 after an intervention. Secondary outcomes include physical fitness measured by a 6 min walk test and stair-climbing test and symptom severity measured by patient-reported questionnaires and pulmonary function. The main hypothesis is that home-based PR is non-inferior to outpatient PR for patients with lung cancer following surgical resection.
The trial has been approved by the Ethical Committee of West China Hospital and is also registered with the Chinese Clinical Trial Registry. The results of this study will be disseminated through peer-reviewed publications and presentations at national and international conferences.

Postoperative pulmonary complications (PPCs) occur after up to 60% of non-cardiac thoracic surgery (NCTS), especially for multimorbid elderly patients. Nevertheless, current risk prediction models for PPCs have major limitations regarding derivation and validation, and do not account for the specific risks of NCTS patients. Well-founded and externally validated models specific to elderly NCTS patients are warranted to inform consent and treatment decisions.
We will develop, internally and externally validate a multivariable risk model to predict 30-day PPCs in elderly NCTS patients. Our cohort will be generated in three study sites in southern China with a target population of approximately 1400 between October 2021 and December 2023. Candidate predictors have been selected based on published data, clinical expertise and epidemiological knowledge. Our model will be derived using the combination of multivariable logistic regression and bootstrapping technique to lessen predictors. The final model will be internally validated using bootstrapping validation technique and externally validated using data from different study sites. A parsimonious risk score will then be developed on the basis of beta estimates derived from the logistic model. Model performance will be evaluated using area under the receiver operating characteristic curve, max-rescaled Brier score and calibration slope. In exploratory analysis, we will also assess the net benefit of Probability of PPCs Associated with THoracic surgery in elderly patients score in the complete cohort using decision curve analysis.
Ethical approval has been obtained from the Institutional Review Board of the Affiliated Cancer Hospital and Institute of Guangzhou Medical University, the Second Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine and the University of Hongkong-Shenzhen Hospital, respectively. The final risk prediction model will be published in an appropriate journal and further disseminated as an online calculator or nomogram for clinical application. Approved and anonymised data will be shared.

OBJECTIVE: Camrelizumab is a selective, humanised, high-affinity IgG4 kappa monoclonal antibody against programmed cell death 1 that shows effective antitumour activity with acceptable toxicity in multiple tumour types. The CameL trial demonstrated that camrelizumab plus chemotherapy (CC) significantly prolonged the median progression-free survival and median overall survival versus chemotherapy alone (CA) in patients with advanced non-squamous non-small cell lung cancer (NSCLC). Our study was conducted to investigate the cost-effectiveness of the two strategies in chemotherapy-naive patients with advanced non-squamous NSCLC.
METHODS: A Markov simulation model was generated based on the CameL trial. The two simulated treatments included CC and CA.
METHODS: Utility was derived from published literature, and costs were calculated based on those at our hospital in Chengdu, China. Incremental cost-effectiveness ratios (ICERs) were calculated to compare the cost-effectiveness of the two treatment arms.
RESULTS: In the overall population, the total costs were $27 223.40 and $13 740.10 for CC and CA treatment, respectively. The CC treatment produced 1.37 quality-adjusted life years (QALYs), and the CA treatment produced 1.17 QALYs. Hence, patients who were in the CC group spent an additional $13 483.30 and generated an increase of 0.20 QALYs, resulting in an ICER of $67 416.50 per QALY.
CONCLUSIONS: For chemotherapy-naive patients with advanced non-squamous NSCLC, CC is not considered a cost-effective treatment versus CA in China when considering a willingness-to-pay threshold of $31 500 per QALY.
