Yuan J, Xu F, Sun Y, Ren H, Chen M, Feng S. Shared decision-making in the management of pulmonary nodules: a systematic review of quantitative and qualitative studies. BMJ Open 2024; 14:e079080. [PMID: 38991667 PMCID: PMC11243204 DOI: 10.1136/bmjopen-2023-079080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 06/26/2024] [Indexed: 07/13/2024] Open
Abstract
OBJECTIVE The objective of this systematic review was to explore the evidence regarding shared decision-making (SDM) in the management of pulmonary nodules. DESIGN Systematic review of quantitative and qualitative studies. DATA SOURCE 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. ELIGIBILITY CRITERIA 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 Grey literature and literature that had not been peer reviewed were excluded.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. DATA EXTRACTION AND SYNTHESIS 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.

Abstract
OBJECTIVES Mesothelioma is an aggressive cancer predominantly affecting the lung and abdominal linings. It can have a unique impact on mental health and well-being (MHWB) due to its incurability, poor prognosis and asbestos-exposure causation. This review's aims were to identify/synthesise international evidence on mesothelioma's MHWB impacts; explore MHWB interventions used by patients and carers; and identify evidence of their effectiveness. DESIGN Systematic review. DATA SOURCES Databases, searched March 2022 and March 2024, were MEDLINE; CINAHL; PsycINFO; Cochrane Library; ASSIA. ELIGIBILITY CRITERIA We included study designs focusing on psychological impacts of living with mesothelioma and MHWB interventions used by patients and informal carers, published in English since January 2002. DATA EXTRACTION AND SYNTHESIS A team of reviewers screened included studies using standardised methods. Quality was assessed using validated tools: Mixed-Methods Appraisal tool for primary research and Joanna Briggs Institute Critical Appraisal Checklist for Systematic Reviews. RESULTS Forty-eight studies met the inclusion criteria: 20 qualitative, 16 quantitative, nine reviews, two mixed-methods, one combined systematic review/qualitative study. UK studies predominated. Many MHWB impacts were reported, including traumatic stress, depression, anxiety and guilt. These were influenced by mesothelioma's causation, communication issues and carer-patient relational interactions. Participants used wide-ranging MHWB interventions, including religious/spiritual practice; talking to mental-health professionals; meaning-making. Some strategies were presented as unhelpful, for example, denial. Participants reported lack of access to support. CONCLUSIONS Most qualitative studies were rated high quality. The quality of the quantitative studies and reviews varied. The sparse literature regarding MHWB in mesothelioma means more research is needed into impacts on patients and carers, including trauma. To enable access to evidence-based support, research is recommended concerning MHWB interventions' effectiveness in mesothelioma. PROSPERO REGISTRATION NUMBER CRD42022302187.

[PMID: 38582540 PMCID: PMC11002354 DOI: 10.1136/bmjopen-2023-077090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 03/21/2024] [Indexed: 04/08/2024] Open
Abstract
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. DESIGN 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. OUTCOME MEASURES 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.

Abstract
INTRODUCTION In a small percentage of patients, pulmonary nodules found on CT scans are early lung cancers. Lung cancer detected at an early stage has a much better prognosis. The British Thoracic Society guideline on managing pulmonary nodules recommends using multivariable malignancy risk prediction models to assist in management. While these guidelines seem to be effective in clinical practice, recent data suggest that artificial intelligence (AI)-based malignant-nodule prediction solutions might outperform existing models. METHODS AND ANALYSIS This study is a prospective, observational multicentre study to assess the clinical utility of an AI-assisted CT-based lung cancer prediction tool (LCP) for managing incidental solid and part solid pulmonary nodule patients vs standard care. Two thousand patients will be recruited from 12 different UK hospitals. The primary outcome is the difference between standard care and LCP-guided care in terms of the rate of benign nodules and patients with cancer discharged straight after the assessment of the baseline CT scan. Secondary outcomes investigate adherence to clinical guidelines, other measures of changes to clinical management, patient outcomes and cost-effectiveness. ETHICS AND DISSEMINATION This study has been reviewed and given a favourable opinion by the South Central-Oxford C Research Ethics Committee in UK (REC reference number: 22/SC/0142).Study results will be available publicly following peer-reviewed publication in open-access journals. A patient and public involvement group workshop is planned before the study results are available to discuss best methods to disseminate the results. Study results will also be fed back to participating organisations to inform training and procurement activities. TRIAL REGISTRATION NUMBER NCT05389774.

Multimodality local consolidative treatment versus conventional care of advanced lung cancer after first-line systemic anti-cancer treatment: study protocol for the RAMON multicentre randomised controlled trial with an internal pilot. BMJ Open 2023; 13:e081650. [PMID: 38072470 PMCID: PMC10729108 DOI: 10.1136/bmjopen-2023-081650] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/02/2023] [Accepted: 11/16/2023] [Indexed: 12/18/2023] Open
Abstract
INTRODUCTION Lung cancer is the most common cause of cancer death worldwide and most patients present with extensive disease. One-year survival is improving but remains low (37%) despite novel systemic anti-cancer treatments forming the current standard of care. Although new therapies improve survival, most patients have residual disease after treatment, and little is known on how best to manage it. Therefore, residual disease management varies across the UK, with some patients receiving only maintenance systemic anti-cancer treatment while others receive local consolidative treatment (LCT), alongside maintenance systemic anti-cancer treatment. LCT can be a combination of surgery, radiotherapy and/or ablation to remove all remaining cancer within the lung and throughout the body. This is intensive, expensive and impacts quality of life, but we do not know if it results in better survival, nor the extent of impact on quality of life and what the cost might be for healthcare providers. The RAMON study (RAdical Management Of Advanced Non-small cell lung cancer) will evaluate the acceptability, effectiveness and cost-effectiveness of LCT versus no LCT after first-line systemic treatment for advanced lung cancer. METHODS AND ANALYSIS RAMON is a pragmatic open multicentre, parallel group, superiority randomised controlled trial. We aim to recruit 244 patients aged 18 years and over with advanced non-small-cell lung cancer from 40 UK NHS hospitals. Participants will be randomised in a 1:1 ratio to receive LCT alongside maintenance treatment, or maintenance treatment alone. LCT will be tailored to each patient's specific disease sites. Participants will be followed up for a minimum of 2 years. The primary outcome is overall survival from randomisation. ETHICS AND DISSEMINATION The West of Scotland Research Ethics Committee (22/WS/0121) gave ethical approval in August 2022 and the Health Research Authority in September 2022. Participants will provide written informed consent before participating in the study. Findings will be presented at international meetings, in peer-reviewed publications, through patient organisations and notifications to patients. TRIAL REGISTRATION NUMBER ISRCTN11613852.

BMJ Open 2023; 13:e075463. [PMID: 37699626 PMCID: PMC10503350 DOI: 10.1136/bmjopen-2023-075463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Accepted: 08/30/2023] [Indexed: 09/14/2023] Open
Abstract
OBJECTIVES To estimate the evolution of quality indicators (30-day mortality and failure-to-rescue) inpatients who underwent lung cancer surgery in France over the past 15 years and to study the potential influencing factors. DESIGN Retrospective cohort study using data from the French hospital database (PMSI). SETTING Nationwide population-based study. PARTICIPANTS All patients who underwent pulmonary resection for lung cancer in France (2005-2020) were included (N=1 57 566). Characteristics of patients (age, gender, comorbidities), surgery (surgical approach, type of resection, extent of resection) and hospital (type of hospital, hospital volume for pulmonary resections) were retrieved. PRIMARY AND SECONDARY OUTCOME MEASURES We studied two outcome indicators: 30-day mortality and failure-to-rescue. We used regression-based techniques (including interrupted time-series) to assess the effects of patient and hospital characteristics on 30-day mortality and failure-to-rescue (number of deaths among patients with at least one major postoperative complication within the 30 days after surgery), adjusting for case mix. RESULTS The 30-day mortality rate increased from 3.8% in 2005 to 4.9% in 2010 and then decreased to 2.9% in 2020. The failure-to-rescue rate decreased from 12.2% in 2005 to 7.1% in 2020. The pneumonectomy rate decreased significantly over time (18.1% in 2005 to 4.8% in 2020) and had the greatest contribution on the reduction of mortality between two periods (2005-2010/2015-2020). The use of video-assisted thoracoscopic surgery or robot-assisted surgery had a great influence on the reduction of mortality (16% of the observed difference in mortality) between the two periods, as did hospital volume. CONCLUSIONS The change in surgical practices, particularly the reduction in pneumonectomies, could be one of the main reasons for reduction in postoperative mortality and failure-to-rescue in France since 2011. Hospital volume is another important factor in reducing postoperative mortality. Our study should encourage the use of technological or organisational innovation, such as changes in surgical practice and cancer surgery authorisations, to improve quality of care.

Cost-effectiveness analysis of serplulimab combined with chemotherapy in the treatment of extensive-stage small-cell lung cancer from the perspective of the healthcare system in China. BMJ Open 2023; 13:e072106. [PMID: 37586861 PMCID: PMC10432650 DOI: 10.1136/bmjopen-2023-072106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Accepted: 07/20/2023] [Indexed: 08/18/2023] Open
Abstract
OBJECTIVE 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. DESIGN 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. OUTCOME MEASURES Total costs, incremental costs, life years, quality-adjusted life years (QALYs), incremental QALYs and incremental cost-effectiveness ratio (ICER). RESULTS 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. CONCLUSIONS 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.

Abstract
OBJECTIVES Workers in the construction industry have been exposed to asbestos in various occupations. In Italy, a National Mesothelioma Registry has been implemented more than 20 years ago. Using cases selected from this registry and exploiting existing control data sets, we estimated relative risks for pleural mesothelioma (PM) among construction workers. DESIGN Case-control study. SETTING Cases from the National Mesothelioma Registry (2000-2018), controls from three previous case-control studies. METHODS We selected male PM incident cases diagnosed in 2000-2018. Population controls were taken from three studies performed in six Italian regions within two periods (2002-2004 and 2012-2016). Age-adjusted and period-adjusted unconditional logistic regression models were fitted to estimate odds ratios (OR) for occupations in the construction industry. We followed two approaches, one (primary) excluding and the other (secondary) including subjects employed in other non-construction blue collar occupations for >5 years. For both approaches, we performed an overall analysis including all cases and, given the incomplete temporal and geographic overlap of cases and controls, three time or/and space restricted sensitivity analyses. RESULTS The whole data set included 15 592 cases and 2210 controls. With the primary approach (4797 cases and 1085 controls), OR was 3.64 (2181 cases) for subjects ever employed in construction. We found elevated risks for blue-collar occupations (1993 cases, OR 4.52), including bricklayers (988 cases, OR 7.05), general construction workers (320 cases, OR 4.66), plumbers and pipe fitters (305 cases, OR 9.13), painters (104 cases, OR 2.17) and several others. Sensitivity analyses yielded very similar findings. Using the secondary approach, we observed similar patterns, but ORs were remarkably lower. CONCLUSIONS We found markedly increased PM risks for most occupations in the construction industry. These findings are relevant for compensation of subjects affected with mesothelioma in the construction industry.

Abstract
OBJECTIVES To assess key elements of the design for Meso-ORIGINS (Mesothelioma Observational study of RIsk prediction and Generation of paired benign-meso tissue samples, Including a Nested MRI Substudy), an ambitious, UK-wide, prospective study that will collect ≥63 matched benign-mesothelioma tissue pairs through longitudinal surveillance and repeat biopsy of patients with asbestos-associated pleural inflammation (AAPI). DESIGN A multicentre, mixed-methods feasibility study, comprising a prospective observational element, evaluating recruitment feasibility, technical feasibility of repeat local anaesthetic thoracoscopy (LAT) and patient acceptability, and a retrospective cohort study focused on AAPI-mesothelioma evolution rate, informing sample size. SETTING 4 UK pleural disease centres (February 2019-January 2020). PARTICIPANTS Patients with AAPI (history or typical imaging plus appropriate pleural histology) were eligible for both elements. In August 2019, eligibility for the prospective element was broadened, including addition of radiological AAPI for technical feasibility and patient acceptability endpoints only. Retrospective cases required ≥2 years follow-up. OUTCOME MEASURES A prospective recruitment target was set a priori at 27 histological AAPI cases (or 14 in any 6 months). Technical feasibility and patient acceptability were determined at 6-month follow-up by thoracic ultrasound surrogates and questionnaires, respectively. Retrospective malignant pleural mesothelioma evolution rate was defined by proportion (95% CI). Baseline predictors of evolution were identified using logistic regression. RESULTS 296 patients with AAPI (39 prospective, 257 retrospective) were recruited/selected. 21/39 prospective recruits were histologically diagnosed (target n=27). Repeat LAT was technically feasible and acceptable in 13/28 (46%) and 24/36 (67%) cases with complete follow-up data. Mesothelioma evolution was confirmed histologically in 36/257 retrospective cases (14% (95% CI 10.3% to 18.8%)) and associated with malignant CT features (OR 4.78 (95% CI 2.36 to 9.86)) and age (OR 1.06 (95% CI 1.02 to 1.12)). CONCLUSIONS Our initial eligibility criteria were too narrow. Meso-ORIGINS will recruit a broader cohort, including prevalent cases, any biopsy type and patients with malignant CT features. A range of rebiopsy techniques will be allowed, accounting for technical and patient factors. The sample size has been reduced to 500. TRIAL REGISTRATION NUMBER ISRCTN12840870.

Abstract
INTRODUCTION There is significant potential to improve outcomes for patients with lung cancer in terms of quality of life and survival. There is some evidence that prehabilitation can help, but, to date, this has only been tested in surgical populations, despite 70%-80% of patients with lung cancer in the UK receiving non-surgical treatment. The physiological and psychological benefits of prehabilitation seen in surgical patients could be extrapolated to those receiving non-surgical treatment, particularly in such a poor prognosis group. With patients and healthcare professionals, we have co-designed a personalised and evidence-based prehabilitation programme. This draws on a conceptual framework that aligns with patient values and needs as well as functional goals. We aim to investigate whether this programme is feasible to implement and evaluate in clinical practice. METHODS AND ANALYSIS An open-label, single-group feasibility study incorporating quantitative assessments, a qualitative free text questionnaire and reflective field notes. Thirty participants will be recruited over an eight-month period from a single London teaching hospital. All recruited participants will receive a personalised prehabilitation programme during their oncological treatment. This includes a one-hour face-to-face appointment prior to, at week three and at week six of their treatment regimen as well as a weekly telephone call. Interventions including nutrition, physical activity and psychological well-being are stratified according to a patient's priorities, level of readiness and expressed needs. The primary outcome will be feasibility of the personalised prehabilitation programme in clinical practice by investigating areas of uncertainty regarding patient recruitment, attrition, treatment fidelity, intervention adherence and acceptability of study outcome measures. Secondary outcomes will include quality of life, functional capacity and grip strength. ETHICS AND DISSEMINATION Ethical approval has been obtained from the Health Research Authority (reference number 22/PR/0390). Results of this study will be disseminated through publication in peer-reviewed articles, presentations at scientific conferences and in collaboration with patient and public involvement representatives.

Abstract
OBJECTIVES 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
OBJECTIVE Describe characteristics, treatment patterns and clinical outcomes of patients with small-cell lung cancer (SCLC). DESIGN Retrospective chart review study defining several cohorts: (1) limited-stage disease (LD) SCLC initiating 1L therapy (1 L LD-SCLC), (2) extensive-stage disease (ED) SCLC initiating 1L therapy (1L ED-SCLC) and (3) patients initiating 2L therapy. SETTING 39 physicians (medical oncologists, thoracic oncologists and/or pulmonologists) from France, Italy and the UK. PARTICIPANTS Patients >18 years of age with a confirmed diagnosis of LD-SCLC or ED-SCLC and a full oncology medical history. Patients included initiated a 1L (2013-2015) or 2L (2013-2016) treatment (chemotherapy and/or radiotherapy-RT). PRIMARY AND SECONDARY OUTCOME MEASURES Overall survival (OS) and progression-free survival (PFS). RESULTS 231 patients in 1L LD-SCLC, 308 in 1L ED-SCLC and 225 with relapse/refractory SCLC initiating 2L treatment were included. The proportion of men was higher across all groups (56.8% to 68.5%) and mean age at time of diagnosis was 66.0 and 65.4 years in 1L LD-SCLC and 2L ED-SCLC cohorts. The majority of patients in LD-SCLC 1L group received chemotherapy with RT (76.2%). Patients initiating 2L therapy predominantly received chemotherapy alone (79.6%).Median OS in 1 L patients was 17.3 months in LD-SCLC and 8.8 months in ED-SCLC. Median PFS was 11.6 months in LD-SCLC and 6.1 months in ED-SCLC patients. Median OS in patients initiating 2L treatment was 6.6 months. OS from start of 2L treatment was lower in patients initially diagnosed with ED (5.1 months) than in patients initially diagnosed with LD (9.3 months) (p<0.0001). OS and PFS were assessed from the start of 1L or 2L therapy, depending on the cohort. CONCLUSIONS Despite the availability of a high number of treatments and combinations, the prognosis of SCLC is still unsatisfactory, especially for those patients diagnosed with ED-SCLC, indicating high unmet need in this patient population.

Abstract
OBJECTIVES To systematically evaluate the efficacy and safety of anaplastic lymphoma kinase (ALK) inhibitors in ALK-rearranged positive non-small cell lung cancer (NSCLC) with brain metastases, and update the overall survival (OS) outcomes of the second-generation and third-generation ALK (ALK-2ndG/3rdG) inhibitors versus first-generation (ALK-1stG) inhibitors. DESIGN The study is in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. Randomised controlled trials (RCTs) published up to 3 November 2021 were retrieved from PubMed, EMBASE, Cochrane Library and ClinicalTrials.gov. SETTING RCTs from any country and healthcare setting. PARTICIPANTS Patients with advanced ALK-positive NSCLC with or without brain metastases. INTERVENTIONS AND COMPARISONS The interventions were ALK-2ndG/3rdG; the control arm was ALK-1stG or crizotinib. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcomes included median progression-free survival and median OS. Secondary outcomes included systemic objective response rate, intracranial response rate and rate of grade ≥3 adverse events (AEs). RESULTS A total of 12 RCTs involving 3156 patients were analysed. Compared with ALK-1stG (crizotinib), ALK-2ndG (alectinib, brigatinib, ceritinib and ensartinib) significantly improved the OS (HR: 0.72, 95% CI: 0.57 to 0.90, p=0.004) and intracranial response of patients with any brain metastases, especially with measurable (diameter ≥10 mm) brain metastases. Network meta-analysis demonstrated that ALK-3rdG (lorlatinib) had superior efficacy for patients with brain lesions, but performed a distinct side-effect profile. Moreover, alectinib showed superior efficacy and lower toxicity in ALK-positive NSCLC. CONCLUSION Treatment with ALK-2ndG inhibitors significantly improved OS compared with crizotinib, and alectinib has less severe AEs than any other ALK inhibitors with moderate-high efficacy. The limited OS follow-up and inadequate sample sizes might contribute to having no statistically significant difference in OS of lorlatinib versus crizotinib. More high-quality and longer follow-up RCTs are warranted to prove our findings. PROSPERO REGISTRATION NUMBER CRD42021292245.

Abstract
INTRODUCTION Although molecular testing is crucial for many patients with lung cancer, the decision to carry out molecular testing is not easy to make in actual clinical scenarios. Using a specific decision aid (DA) to conduct shared decision-making (SDM) may help ameliorate this problem. However, no DA currently exists for lung cancer molecular testing (DA_LCMT). We aim to develop an evidence-based, iteratively refined DA, which may facilitate SDM and improve the quality of SDM. METHODS AND ANALYSIS After considering the Ottawa Decision Support Framework, International Patient Decision Aid Standards and Food and Drug Administration guidance about methods to identify what is important to patients, semistructured interviews with qualitative research methods will be used to generate the decision-making needs of patients with lung cancer diagnosed with lung adenocarcinoma by intraoperative frozen pathological sections. Input will be provided by patients and other stakeholders, including thoracic surgeons, nurses, hospital administrators, molecular testing company staff and insurance company staff. Then, a modified Delphi method will be used to develop the DA_LCMT V.1.0 (DA_LCMT 1.0). Structured interviews with qualitative research methods will be used in the cognitive debriefing (alpha tests) and field testing (beta tests) to revise and improve the DA_LCMT from version 1.0 to the final version, version 3.0. Descriptive statistics will be used to summarise the baseline characteristics of the patients and other stakeholders. Qualitative data will be analysed using the three steps of grounded theory: generate a codebook, update the codebook and create a comprehensive list of related items. ETHICS AND DISSEMINATION Ethics Committee for Medical Research and New Medical Technology of Sichuan Cancer Hospital approved this study. This protocol is based on the latest version 1.0, dated 31 October 2021. The study was also approved by the Ethics Committees of The Third People's Hospital of Chengdu, Zigong First People's Hospital and Jiangyou People's Hospital. The results of this study will be presented at medical conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT05191485.

Abstract
INTRODUCTION The use of monitored anaesthesia care (MAC) is necessary and ubiquitous for fiberoptic bronchoscopy. Anaesthetic management of patients with severe tracheal stenosis has always been a challenge. The efficacy and safety of the MAC with sufentanil target controlled infusion (TCI) and remifentanil TCI in patients with severe tracheal stenosis are still unknown. METHODS ANALYSIS This study is a prospective, investigator-initiated, two-arm, randomised control trial to compare the efficacy and safety of sufentanil TCI with remifentanil TCI in patients with severe tracheal stenosis undergoing fiberoptic bronchoscopy. 270 patients will be randomly assigned to the sufentanil TCI group or remifentanil TCI group, with a 1:1 ratio in two groups. The primary outcome is the incidence of hypoxaemia (an oxygen saturation of <90%). The secondary outcome investigates the severity of hypoxaemia, cough severity, haemodynamic variables, sedation scores and satisfaction scores. ETHICS AND DISSEMINATION The study has been approved by the Medical Ethics Committee of Shanghai Pulmonary Hospital (approval No. K19-122). The results will be submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER ChiCTR2100043380.

Abstract
OBJECTIVES Combination treatment with erlotinib plus bevacizumab has the potential to become a standard treatment regimen for patients with epidermal growth factor receptor mutation-positive (EGFRm+) advanced non-small cell lung cancer (NSCLC). This study aimed to investigate the efficacy and safety of erlotinib plus bevacizumab in patients with EGFRm+ advanced NSCLC. DESIGN Systematic review and meta-analysis. DATA SOURCES The PubMed, Embase, Web of Science and Cochrane Library databases were searched, from inception to 15 January 2022. ELIGIBILITY CRITERIA We included randomised controlled trials (RCTs), reported in English, assessing the efficacy of erlotinib plus bevacizumab versus erlotinib monotherapy in patients with EGFRm + advanced NSCLC. DATA EXTRACTION AND SYNTHESIS The main objective was to assess overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and adverse events (AEs). Two independent reviewers extracted data and assessed the risk of bias. A random-effects model was used where there was evidence for homogeneous effects. RESULTS Four RCTs (reported across six publications) were included in the meta-analysis, with a total of 775 patients included in the pooled analyses of PFS, OS and ORR (387 in the erlotinib plus bevacizumab intervention group and 388 in the erlotinib group). Compared with the erlotinib alone group, the erlotinib plus bevacizumab group achieved a significantly prolonged PFS (HR: 0.59; 95% CI 0.49 to 0.72; p<0.00001; I2=0%), but OS (HR: 0.95; 95% CI 0.78 to 1.15; p=0.59; I2=0%) and ORR (OR: 1.25; 95% CI 0.89 to 1.74; p=0.19; I2=0%) were not significantly prolonged. A total of 776 cases were used for a pooled analysis of AEs. Regarding AEs, combined treatment significantly increased the incidence of diarrhoea (51% vs 43%, 95% CI 1.03 to 1.38; p=0.006), haemorrhagic events (41% vs 20%, 95% CI 1.12 to 6.31; p=0.03), proteinuria (25% vs 3%, 95% CI 4.86 to 17.66; p<0.0001) and hypertension (40% vs 8%, 95% CI 3.66 to 7.88; p<0.0001). CONCLUSIONS Erlotinib plus bevacizumab for the treatment of patients with EGFRm+ advanced NSCLC was associated with significantly prolonged PFS compared with erlotinib alone, but the combination did not prolong OS.

Abstract
OBJECTIVE This study aimed to compare the efficacy and safety of different platinum adjuvant chemotherapy regimens for early-stage resected non-small-cell lung cancer (NSCLC). DESIGN Systematic review with network meta-analysis of randomised trials. DATA SOURCES PubMed, EMBASE, The Cochrane Library, Web of Science and Scopus Google Scholar were searched through 12 March 2021. ELIGIBILITY CRITERIA Eligible randomised controlled trials (RCTs) comparing the postoperative platinum chemotherapy regimen with the observation-controlled group or comparing two platinum chemotherapy regimens head-to-head were included. DATA EXTRACTION AND SYNTHESIS The primary outcome was the efficacy of adjuvant chemotherapy regimens including relapse-free survival (RFS), overall survival (OS), 2-year, 3-year, 5-year RFS rate and OS rate. The secondary outcome was the rate of grade 3-4 toxicity assessments. Cochrane Handbook (V.5) was used for the risk of bias assessment. Analyses were performed using R software V.4.3.1. RESULTS 20 RCTs with a sample size of 5483 were enrolled in meta-analysis. The chemotherapy group had a significant RFS and OS advantage compared with the observation group (HR 0.67; 95% CI 0.56 to 0.81, p<0.0001; HR 0.80; 95% CI, 0.73 to 0.88, p<0.0001, respectively). Compared with the observation arm, only the 'cisplatin_vinorelbine' regimen had a significant RFS and OS advantage (HR 0.63; 95% CI 0.43 to 0.87; HR 0.74; 95% CI 0.63 to 0.87, respectively) while the remaining chemotherapy regimens had no significant difference of efficacy compared with the observation group. In terms of the safety of adjuvant chemotherapy, the incidence of haematological toxicities and nausea/vomiting was not significantly higher in the 'cisplatin_vinorelbine' arm than in other chemotherapy group. CONCLUSION This study summarised the adjuvant cytotoxicity chemotherapy regimens for patients with early-stage resected NSCLC. Our analysis may provide some guiding significance for the clinicians when determining the optimal chemotherapy regimen.

Abstract
INTRODUCTION Immunotherapy is the fourth leading therapy for lung cancer following surgery, chemotherapy and radiotherapy. Recently, several studies have reported about the potential association between the gut microbiome and therapeutic response to immunotherapy. Nevertheless, the specific composition of the gut microbiome or combination of gut microbes that truly predict the efficacy of immunotherapy is not definitive. METHODS AND ANALYSIS The present multicentre, prospective, observational study aims to discover the specific composition of the gut microbiome or combination of gut microbes predicting the therapeutic response to immunotherapy in lung cancer using artificial intelligence. The main inclusion criteria are as follows: (1) pathologically or cytologically confirmed metastatic or postoperative recurrent lung cancer including non-small cell lung cancer and small cell lung cancer; (2) age≥20 years at the time of informed consent; (3) planned treatment with immunotherapy including combination therapy and monotherapy, as the first-line immunotherapy; and (4) ability to provide faecal samples. In total, 400 patients will be enrolled prospectively. Enrolment will begin in 2021, and the final analyses will be completed by 2024. ETHICS AND DISSEMINATION The study protocol was approved by the institutional review board of each participating centre in 2021 (Kyushu Cancer Center, IRB approved No. 2021-13, 8 June 2021 and Kyushu Medical Center, IRB approved No. 21-076, 31 August 2021). Study results will be disseminated through peer-reviewed journals and national and international conferences. TRIAL REGISTRATION NUMBER UMIN000046428.

Abstract
INTRODUCTION Immunotherapy (IO) has transformed the treatment paradigm for a wide variety of solid tumours. However, assessment of response can be challenging with conventional radiological imaging (eg, iRECIST), which do not precisely capture the unique response patterns of tumours treated with IO. Emerging data suggest that circulating tumour DNA (ctDNA) can aid in response assessment in patients with solid tumours receiving IO. The short half-life of ctDNA puts it in a unique position for early treatment response monitoring. The BESPOKE IO study is designed to investigate the clinical utility of serial ctDNA testing to assess treatment response using a tumour-informed, bespoke ctDNA assay (Signatera) and to determine its impact on clinical decision-making with respect to continuation/discontinuation, or escalation/de-escalation of immunotherapy in patients with advanced solid tumours. METHODS AND ANALYSIS The BESPOKE IO is a multicentre, prospective, observational study with a goal to enroll over 1500 patients with solid tumours receiving IO in up to 100 US sites. Patients will be followed for up to 2 years with serial ctDNA analysis, timed with every other treatment cycle. The primary endpoint is to determine the percentage of patients who will have their treatment regimen changed as guided by post-treatment bespoke ctDNA results along with standard response assessment tools. The major secondary endpoints include progression-free survival, overall survival and overall response rate based on the ctDNA dynamics. ETHICS AND DISSEMINATION The BESPOKE IO study was approved by the WCG Institutional Review Board (Natera-20-043-NCP BESPOKE Study of ctDNA Guided Immunotherapy (BESPOKE IO)) on 22 February 2021. Data protection and privacy regulations will be strictly observed in the capturing, forwarding, processing and storing patients' data. Natera will approve the publication of any study results in accordance with the site-specific contract. TRIAL REGISTRATION NUMBER NCT04761783.

Abstract
OBJECTIVES Cancer cell has aberrant metabolism. The purpose of this study aimed to investigate relationships between maximum standard uptake value (SUVmax)of 18fluoro-2-deoxy-d-glucose and T stages, histological grades and pathological subtypes of lung adenocarcinoma. DESIGN Retrospective cohort study, employing the Kruskal-Wallis, Bonferroni-Dunn and Mann-Whitney tests to compare SUVmax of different T stages, histological grades and pathological subtypes of lung adenocarcinoma. SETTING The outpatients who had aberrant positron emission tomography/CT (PET/CT) images in chest were enrolled this study from August 2016 to November 2018 in Shanghai, China. PARTICIPANT Initial 11 270 patients with suspected lung cancer who underwent PET/CT examinations were surveyed. A total of 1454 patients who were diagnosed as lung adenocarcinoma by pathologist were included in this project. PRIMARY OUTCOME MEASURES SUVmax value at different tumour-node-metastasis stages of lung adenocarcinoma before surgery. RESULTS The mean SUVmax of patients with lung adenocarcinoma was significantly elevated with the increase in T stages. There were significant evident differences in SUVmax among T1a-T1c (p<0.05). However, after the staging of patients was more than T1 stage, SUVmax of T2a, T2b, T2 visceral pleural invasion, T3 and T4 had not dramatic changes. SUVmax value of lung adenocarcinoma in the same T stage group was the highest in patients with the high grade of malignancy and solid-predominant invasive adenocarcinoma. CONCLUSIONS SUVmax value was significantly associated with T stages, grades of malignancy and pathological subtypes of lung adenocarcinoma.

Abstract
OBJECTIVES Lung cancer screening using low-dose CT may be not effective without considering the presence of comorbidities related to chronic smoking. The aim of the study was to establish the prevalence of chronic obstructive pulmonary disease (COPD) in group of phighlight the potential benefits atients participating in the largest Polish lung cancer screening programme MOLTEST-BIS and attempt to confirm the necessity of combined lung cancer and COPD screening. DESIGN Cohort, prospective study. SETTING Medical University of Gdańsk, Poland PARTICIPANTS: The study included 754 participants in lung cancer screening trial from the Pomeranian region, aged 50-70 years old, current and former smokers with a smoking history ≥30 pack-years. PRIMARY AND SECONDARY OUTCOME MEASURES Questionnaire, physical examination, anthropometric measurements, spirometry test before and after inhaled bronchodilator (400 µg of salbutamol) RESULTS: Obstructive disorders were diagnosed in 186 cases (103 male and 83 female). In the case of 144 participants (19.73%), COPD was diagnosed. Only 13.3% of participants with COPD were known about the disease earlier. According to classification of airflow limitation 55.6% of diagnosed COPD were in Global Initiative for Chronic Obstructive Lung Disease (GOLD) 1 (mild), 38.9% in GOLD 2 (moderate), 4.9% in GOLD 3 (severe) and 0.7% in GOLD 4 (very severe) stage. Women with recognition of COPD were younger than men (63.7 vs 66.3 age) and they smoked less cigarettes (41.1 vs 51.9 pack-years). CONCLUSIONS Prevalence of COPD in Polish lung cancer screening cohort is significant. The COPD in this group is remarkably under-diagnosed. Most diagnosed COPD cases were in the initial stage of advancement. This early detection of airflow limitation highlights the potential benefits arising from combined oncological-pulmonary screening.NKBBN.

Abstract
OBJECTIVES Ki-67, a marker of cellular proliferation, is associated with prognosis across a wide range of tumours, including gastroenteropancreatic neuroendocrine neoplasms (NENs), lymphoma, urothelial tumours and breast carcinomas. Its omission from the classification system of pulmonary NENs is controversial. This systematic review sought to assess whether Ki-67 is a prognostic biomarker in lung NENs and, if feasible, proceed to a meta-analysis. RESEARCH DESIGN AND METHODS Medline (Ovid), Embase, Scopus and the Cochrane library were searched for studies published prior to 28 February 2019 and investigating the role of Ki-67 in lung NENs. Eligible studies were those that included more than 20 patients and provided details of survival outcomes, namely, HRs with CIs according to Ki-67 percentage. Studies not available as a full text or without an English manuscript were excluded. This study was prospectively registered with PROSPERO. RESULTS Of 11 814 records identified, seven studies met the inclusion criteria. These retrospective studies provided data for 1268 patients (693 TC, 281 AC, 94 large cell neuroendocrine carcinomas and 190 small cell lung carcinomas) and a meta-analysis was carried out to estimate a pooled effect. Random effects analyses demonstrated an association between a high Ki-67 index and poorer overall survival (HR of 2.02, 95% CI 1.16 to 3.52) and recurrence-free survival (HR 1.42; 95% CI 1.01 to 2.00). CONCLUSION This meta-analysis provides evidence that high Ki-67 labelling indices are associated with poor clinical outcomes for patients diagnosed with pulmonary NENs. This study is subject to inherent limitations, but it does provide valuable insights regarding the use of the biomarker Ki-67, in a rare tumour. PROSPERO REGISTRATION NUMBER CRD42018093389.

Abstract
OBJECTIVES To investigate the relationship among baseline health-related quality of life (HRQoL), early changes in HRQoL from baseline to completion of the first cycle of chemotherapy, and prognosis in patients with advanced lung cancer. DESIGN This was a prospective, observational study. SETTING The study was conducted in a national cancer centre in South China. PARTICIPANTS A total of 243 patients with chemo-naïve with advanced lung cancer were enrolled. INTERVENTION None. PRIMARY AND SECONDARY OUTCOME MEASURES The Functional Assessment of Cancer Therapy-Lung was used to assess HRQoL at baseline and at the end of the first cycle of chemotherapy. The Trial Outcome Index (TOI) and Lung Cancer Scale (LCS) were calculated as predictive indicators. Response to treatment was evaluated as per the Response Evaluation Criteria in Solid Tumors (RECIST) V.1.1. Survival data were gathered from follow-up to September 2019. RESULTS Patients with 5-point or greater decreases in TOI (65% vs 48%, adjusted risk ratio (aRR)=2.19, 95% CI 1.09 to 4.41) or 2-point or greater decreases in LCS (72% vs 48%, aRR=3.29, 95% CI 1.50 to 7.22) from baseline to completion of the first cycle of chemotherapy were more likely to show stable or progressive disease than those whose HRQoL had improved. Baseline TOI ≤54 (80.0% vs 69.9%, adjusted hazard risk (aHR)=1.36, 95% CI 1.01 to 1.84) and LCS ≤21 (77.6% vs 72.5%, aHR=1.36, 95% CI 1.01 to 1.83) were associated with higher risk for death compared with TOI>54 and LCS>21. Area under the curve analysis indicated that early changes in LCS and baseline LCS scores could better predict response to treatment and overall survival than the corresponding TOI values. CONCLUSIONS Higher pretreatment HRQoL scores could predict longer survival, while declining HRQoL values could predict unfavourable treatment outcome among patients with advanced lung cancer. The use of the LCS is recommended for the routine collection of patient-reported HRQoL. TRIAL REGISTRATION NUMBER NCT01914120.

Abstract
INTRODUCTION Integrating palliative care (PC) early in the illness course for patients with serious cancers improves their outcomes and is recommended by national organisations such as the American Society of Clinical Oncology. However, monthly visits with PC clinicians from the time of diagnosis can be challenging to implement due to the lack of specialty-trained PC clinicians and resources. Therefore, we developed a stepped care model to triage PC service based on patients' needs. METHODS AND ANALYSIS We are conducting a non-blinded, randomised trial to evaluate the non-inferiority of a stepped PC model compared with an early integrated PC model for improving patients' quality of life (QOL) at 24 weeks (primary outcome). Patients assigned to early integrated PC meet with PC every 4 weeks throughout their illness. Patients assigned to stepped PC have PC visits only at clinically significant points in their illness (eg, cancer progression) unless their QOL decreases, at which time they are 'stepped up' and meet with PC every 4 weeks throughout the remainder of their illness. Secondary aims include assessing whether stepped PC is non-inferior to early integrated PC regarding patient-clinician communication about end of life care and length of stay on hospice as well as comparing resource utilisation. Patients are recruited from the Massachusetts General Hospital Cancer Center, Boston, Massachusetts; Duke Cancer Center, Durham, North Carolina and University of Pennsylvania Abramson Cancer Center, Philadelphia, Pennsylvania. The target sample size is 510 patients. ETHICS AND DISSEMINATION The study is funded by the National Cancer Institute, approved by the Dana-Farber/Harvard Cancer Center Institutional Review Board and will be reported in accordance with the Consolidated Standards of Reporting Trials statement. We will disseminate results through professional society meetings, peer-reviewed publications and presentations to patient organisations. TRIAL REGISTRATION NUMBER NCT03337399.

Abstract
INTRODUCTION There is a strong theoretical rationale for combining checkpoint blockade with cytotoxic chemotherapy in pleural mesothelioma and other cancers. Two recent single-arm, phase 2 trials [DuRvalumab with chEmotherapy as first-line treAtment in advanced pleural Mesothelioma (DREAM) and Phase II multicenter study of anti-PD-L1, durvalumab, in combination with cisplatin and pemetrexed for the first-line treatment of unresectable malignant pleural mesothelioma (PrE0505)] combining the programmed death ligand-1 (PD-L1) inhibitor durvalumab with standard first-line chemotherapy exceeded prespecified safety and activity criteria to proceed to a phase 3 confirmatory trial to assess this combination. We present the protocol of the DREAM3R trial. METHODS AND ANALYSIS This multicentre open-label randomised trial will recruit 480 treatment-naïve adults with advanced pleural mesothelioma, randomised (2:1) to either 3-weekly durvalumab 1500 mg plus 3-weekly doublet chemotherapy (cisplatin 75 mg/m2 or carboplatin, Area Under the Curve,AUC 5 and pemetrexed 500 mg/m2) 4-6 cycles, followed by 4-weekly durvalumab 1500 mg until disease progression, unacceptable toxicity or patient withdrawal; OR doublet chemotherapy alone for 4-6 cycles, followed by observation. The target accrual time is 27 months, with follow-up for an additional 24 months. This provides over 85% power if the true HR for overall survival (OS) is 0.70, with two-sided alpha of 0.05, assuming a median OS of 15 months in the control group. Randomisation is stratified by age (18-70 years vs >70), sex, histology (epithelioid vs non-epithelioid), platinum agent (cisplatin vs carboplatin) and region (USA vs Australia/New Zealand vs Other). The primary endpoint is OS. Secondary endpoints include progression-free survival, objective tumour response (by mRECIST V.1.1 and iRECIST), adverse events, health-related quality of life and healthcare resource use. Tertiary correlative objectives are to explore and validate potential prognostic and/or predictive biomarkers (including features identified in the DuRvalumab with chEmotherapy as first-line treAtment in advanced pleural Mesothelioma (DREAM) and PrE0505 studies, PD-L1 expression, tumour mutational burden, genomic characteristics and human leukocyte antigen subtypes) in tissue and serial blood samples. An imaging databank will be assembled for validation of radiological measures of response, and studies of possible radiomic biomarkers in mesothelioma. ETHICS AND DISSEMINATION The protocol was approved by human research ethics review committees for all participating sites. Results will be disseminated in peer-reviewed journals and at scientific conferences. DRUG SUPPLY AstraZeneca. PROTOCOL VERSION CTC 0231 / TOGA 18/001 / PrE0506 3.0, 29 July 2021.
