Impact on quality of life from multimodality treatment for lung cancer: a randomised controlled feasibility trial of surgery versus no surgery as part of multimodality treatment in potentially resectable stage III-N2 NSCLC (the PIONEER trial).

INTRODUCTION: Optimal treatment for 'potentially resectable' stage III-N2 non-small cell lung cancer (NSCLC) requires multimodality treatment: local treatment (surgery or radiotherapy) and systemic anticancer therapy. There is no clear evidence of superiority for survival between the two approaches and little research has explored quality of life (QOL). This study will inform the design of a phase III randomised trial of surgery versus no surgery as part of multimodality treatment for stage III-N2 NSCLC with QOL as a primary outcome. METHODS AND ANALYSIS: Patient participants will be randomised to receive multimodality treatment (1) with surgery OR (2) without surgery. The Quintet Recruitment Intervention will be used to maximise recruitment. Eligible patients will have 'potentially resectable' N2 NSCLC and have received a multidisciplinary team recommendation for multimodality treatment. Sixty-six patients and their carers will be recruited from 8 UK centres. Patient/carer QOL questionnaires will be administered at baseline, weeks 6, 9, 12 and month 6. Semistructured interviews will be conducted. Quantitative data will be analysed descriptively and qualitative data will be analysed using framework analysis. ETHICS AND DISSEMINATION: Ethical approval has been obtained. Results will be disseminated via publications, national bodies and networks, and patient and public involvement groups. TRIAL REGISTRATION: NCT04540757.

Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration for PD-L1 Testing in Non-small Cell Lung Cancer.

BACKGROUND: Programmed death-ligand 1 (PD-L1) expression on cancer cells is a clinically important biomarker to select patients with non-small cell lung cancer (NSCLC) for treatment with programmed death-1/PD-L1 inhibitors. Clinical trials of immunotherapy in patients with NSCLC have required histologic evidence for PD-L1 testing; in clinical practice, cytologic samples commonly are acquired in patients with advanced disease. RESEARCH QUESTION: This study aims to investigate whether endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) samples are adequate for PD-L1 testing in NSCLC. STUDY DESIGN AND METHODS: This study investigates the sampling adequacy of EBUS-TBNA for PD-L1 testing when compared with other methods. Furthermore, the relationship between clinicopathologic characteristics and PD-L1 expression in the study population have been examined. Five hundred seventy-seven NSCLC specimens were analyzed from consecutive patients with NSCLC across six centers in the United Kingdom and one center in the United States between January 2015 and December 2016. RESULTS: In the EBUS-TBNA group (189 specimens), the overall percentage of patients with successful PD-L1 testing was 94.7%. There was no significant difference in sampling adequacy with other methods of tissue acquisition. Older patients had higher failure rates of PD-L1 testing (OR, 1.06; P = .008). In multivariate analysis, advanced N-stage (P = .048) and presence of brain metastasis (P < .001) were associated with high PD-L1 expression. INTERPRETATION: This large multicenter study shows that EBUS-TBNA provides samples adequate for PD-L1 testing and that advanced N stage and the presence of brain metastasis are associated with high PD-L1 expression.

Is the English Cancer Patient Experience Survey representative? A comparative analysis with the National Lung Cancer Audit.

OBJECTIVES: Healthcare systems increasingly recognise the importance of service users' perspectives for improving care organisation and delivery. The English Cancer Patient Experience Survey (CPES) is carried out annually, however, its representativeness within cancer types is unknown. We have explored if the CPES results are representative of people with lung cancer. MATERIALS AND METHODS: We linked cancer registry data across multiple sources to assess how CPES represents sociodemographic and clinical characteristics of the National Lung Cancer Audit population, accounting for post-sampling mortality bias. Multivariable logistic regression was used to compare people included and not included in CPES. RESULTS: Of 240,375 people diagnosed (2009-2015), 15,967 (7 %) were included in CPES. Gender and ethnicity were reasonably represented, as were sociodemographic and clinical groupings, although more received anti-cancer treatment (96 % of CPES respondents vs. 56 % of patients nationally; adjusted odds ratio = 10.3, 95 % confidence interval 9.4-11.2 for any anti-cancer treatment) with chemotherapy most over-represented, followed by surgery and then radiotherapy. CPES under-represented older, more socioeconomically deprived, and certain clinical groups, including those with worse performance status, multiple comorbidities, and diagnosis via emergency presentation. CONCLUSION: CPES includes patients across the sociodemographic and clinical spectrum indicating its value for research and service planning. Unbalanced representation of incident lung cancer cases is a limitation that must be considered in context of using CPES findings to implement service changes. Although half the national lung cancer population who received no anti-cancer treatment do not have their experiences represented, the strength of this dataset is in providing detailed comparisons of patient experiences across different treatment groups.

Impact of organisation and specialist service delivery on lung cancer outcomes.

INTRODUCTION: Data from the National Lung Cancer Audit (NLCA) often show variation in outcomes between lung cancer units which are not entirely explained by case mix. We explore the association between the organisation of services and patient outcome. METHODS: Details of service provision were collected via an electronic survey in June 2017. An overall organisational score derived from eleven key service factors from national lung cancer commissioning guidance was calculated for each organisation. The results for each hospital were linked to their patient outcome results from the 2015 NLCA cases. Multivariate logistic regression analysis was used to link the organisational score to patient outcomes. RESULTS: Lung cancer unit organisational audit scores varied from 0 to 11. Thirty-eight (29%) units had a score of 0-4, 64 (50%) had a score of 5-7 and 27 (21%) had a score of 8-11. Multivariate regression analysis revealed that, compared with an organisational score of 0-4, patients seen at units with a score of 8-11 had higher 1-year survival (adjusted OR (95% CI)=2.30 (1.04 to 5.08), p<0.001), higher curative-intent treatment rate (adjusted OR (95% CI)=1.62 (1.26 to 2.09), p<0.001) and greater likelihood of receiving treatment within 62 days (adjusted OR (95% CI)=1.49 (1.20 to 1.86), p<0.001). CONCLUSION: National variation in the provision of services and workforce remain. We provide evidence that adherence to the national lung commissioning guidance has the potential to improve patient outcomes within the current service structure.

British Thoracic Society quality standards for the investigation and management of pulmonary nodules.

INTRODUCTION: The purpose of the quality standards document is to provide healthcare professionals, commissioners, service providers and patients with a guide to standards of care that should be met for the investigation and management of pulmonary nodules in the UK, together with measurable markers of good practice. METHODS: Development of British Thoracic Society (BTS) Quality Standards follows the BTS process of quality standard production based on the National Institute for Health and Care Excellence process manual for the development of quality standards. RESULTS: 7 quality statements have been developed, each describing a key marker of high-quality, cost-effective care for the investigation and management of pulmonary nodules, and each statement is supported by quality measures that aim to improve the structure, process and outcomes of healthcare. DISCUSSION: BTS Quality Standards for the investigation and management of pulmonary nodules form a key part of the range of supporting materials that the Society produces to assist in the dissemination and implementation of guideline recommendations.

Apples and pears? A comparison of two sources of national lung cancer audit data in England.

In 2014, the method of data collection from NHS trusts in England for the National Lung Cancer Audit (NLCA) was changed from a bespoke dataset called LUCADA (Lung Cancer Data). Under the new contract, data are submitted via the Cancer Outcome and Service Dataset (COSD) system and linked additional cancer registry datasets. In 2014, trusts were given opportunity to submit LUCADA data as well as registry data. 132 NHS trusts submitted LUCADA data, and all 151 trusts submitted COSD data. This transitional year therefore provided the opportunity to compare both datasets for data completeness and reliability. We linked the two datasets at the patient level to assess the completeness of key patient and treatment variables. We also assessed the interdata agreement of these variables using Cohen's kappa statistic, κ. We identified 26 001 patients in both datasets. Overall, the recording of sex, age, performance status and stage had more than 90% agreement between datasets, but there were more patients with missing performance status in the registry dataset. Although levels of agreement for surgery, chemotherapy and external-beam radiotherapy were high between datasets, the new COSD system identified more instances of active treatment. There seems to be a high agreement of data between the datasets, and the findings suggest that the registry dataset coupled with COSD provides a richer dataset than LUCADA. However, it lagged behind LUCADA in performance status recording, which needs to improve over time.

Resectable Clinical N2 Non-Small Cell Lung Cancer; What Is the Optimal Treatment Strategy? An Update by the British Thoracic Society Lung Cancer Specialist Advisory Group.

Patients and clinicians are faced with uncertainty as to the optimal treatment strategy for potentially resectable NSCLC in which there is clinical evidence of involvement of the ipsilateral mediastinum. Randomized controlled trials and meta-analyses have failed to demonstrate superiority of one bimodality strategy over another (chemotherapy plus surgery versus chemotherapy plus radiotherapy). One trial of trimodality treatment with chemotherapy, radiotherapy, and surgery demonstrated an improvement in progression-free, but not overall, survival versus chemotherapy and radiotherapy. There are a number of limitations to the data in this complex and heterogenous patient group. No randomized controlled trial has specifically studied patients with single-station N2 disease versus multistation N2 disease. When discussing treatment for fit patients with potentially resectable cN2 NSCLC, lung cancer teams should consider trimodality treatment with chemotherapy, radiotherapy, and surgery or bimodality treatment with chemotherapy and either surgery or radiotherapy. We advocate that all patients see both a thoracic surgeon and the oncology team to discuss these different approaches.

Patient characteristics, treatment and survival in pulmonary carcinoid tumours: an analysis from the UK National Lung Cancer Audit.

OBJECTIVES: Pulmonary carcinoid (PC) is a rare tumour with good prognosis following surgical resection. However, little is known regarding patient characteristics and use of other treatments modalities. Our objective was to review patient characteristics, treatment and survival for patients with PC and contrast these results with other forms of non-small cell lung cancer (NSCLC). SETTING: Audit data from UK National Lung Cancer Audit (NLCA) 2008-2013. PARTICIPANTS: 184 906 lung cancer cases were submitted to the NLCA. OUTCOME MEASURES: Primary outcome-survival rates between PC and NSCLC. Secondary outcome-differences in performance status, lung function and treatment modality between PC and NSCLC. RESULTS: PC histology was recorded in 1341 (0.73%) patients and non-carcinoid NSCLC histology in 162 959 (87.4%) cases. 91% of patients with PC had good performance status (Eastern Cooperative Oncology Group (ECOG) 0-1), compared with only 53% of NSCLC. 66% of PC had localised disease. Of all PC cases, 77% were treated with surgery, 6.2% received chemotherapy and 3.6% received radiotherapy, with the remainder treated with best supportive care. Overall 1-year and 3-year survival rates for PC were 92% and 84.7%, respectively. In contrast, 1-year and 3-year survival rates for NSCLC were 36.2% and 15.6%, However, 3-year survival for PC markedly decreased with worsening performance status and advanced disease to 23.8% for performance status ECOG 3-4 and 33.6% for stage IV disease. CONCLUSIONS: In contrast to other forms of NSCLC, the majority of patients with PC present with good performance status, preserved lung function and early stage disease amenable to surgical resection. However, 1 in 5 patients with PC has metastatic disease which is associated with poor prognosis, as is poor performance status at presentation. We believe these data will help clinicians provide accurate prognostic predictions stratified according to patient characteristics at presentation, as well as guide future clinical trials.

Reciprocal peer review for quality improvement: an ethnographic case study of the Improving Lung Cancer Outcomes Project.

BACKGROUND: Peer review offers a promising way of promoting improvement in health systems, but the optimal model is not yet clear. We aimed to describe a specific peer review model-reciprocal peer-to-peer review (RP2PR)-to identify the features that appeared to support optimal functioning. METHODS: We conducted an ethnographic study involving observations, interviews and documentary analysis of the Improving Lung Cancer Outcomes Project, which involved 30 paired multidisciplinary lung cancer teams participating in facilitated reciprocal site visits. Analysis was based on the constant comparative method. RESULTS: Fundamental features of the model include multidisciplinary participation, a focus on discussion and observation of teams in action, rather than paperwork; facilitated reflection and discussion on data and observations; support to develop focused improvement plans. Five key features were identified as important in optimising this model: peers and pairing methods; minimising logistic burden; structure of visits; independent facilitation; and credibility of the process. Facilitated RP2PR was generally a positive experience for participants, but implementing improvement plans was challenging and required substantial support. RP2PR appears to be optimised when it is well organised; a safe environment for learning is created; credibility is maximised; implementation and impact are supported. DISCUSSION: RP2PR is seen as credible and legitimate by lung cancer teams and can act as a powerful stimulus to produce focused quality improvement plans and to support implementation. Our findings have identified how RP2PR functioned and may be optimised to provide a constructive, open space for identifying opportunities for improvement and solutions.

Clinical management of older people with non-small cell lung cancer in England.

Data for 25261 patients with non-small cell lung cancer whose details were submitted to the National Lung Cancer Audit in England were analysed to assess the effect of age at diagnosis on their clinical management, after accounting for sex, stage, performance status and comorbidity. Multivariate logistic regression showed the odds of having histocytological confirmation and anticancer treatment decreased progressively with age, and was also lower in women. It is likely that these results have a multifactorial explanation, and further research into the attitudes of patients, carers and healthcare professionals, and clinical trials of treatment in older populations, are necessary.

Suitability of endobronchial ultrasound-guided transbronchial needle aspiration specimens for subtyping and genotyping of non-small cell lung cancer: a multicenter study of 774 patients.

RATIONALE: The current management of advanced non-small cell lung cancer (NSCLC) requires differentiation between squamous and nonsquamous subtypes as well as epidermal growth factor receptor (EGFR) mutation status. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is increasingly used for the diagnosis and staging of lung cancer. However, it is unclear whether cytology specimens obtained with EBUS-TBNA are suitable for the subclassification and genotyping of NSCLC. OBJECTIVES: To determine whether cytology specimens obtained from EBUS-TBNA in routine practice are suitable for phenotyping and genotyping of NSCLC. METHODS: Cytological diagnoses from EBUS-TBNA were recorded from 774 patients with known or suspected lung cancer across five centers in the United Kingdom between 2009 and 2011. MEASUREMENTS AND MAIN RESULTS: The proportion of patients with a final diagnosis by EBUS-TBNA in whom subtype was classified was 77% (95% confidence interval [CI], 73-80). The rate of NSCLC not otherwise specified (NSCLC-NOS) was significantly reduced in patients who underwent immunohistochemistry (adjusted odds ratio, 0.50; 95% CI, 0.28-0.82; P = 0.016). EGFR mutation analysis was possible in 107 (90%) of the 119 patients in whom mutation analysis was requested. The sensitivity, negative predictive value, and diagnostic accuracy of EBUS-TBNA in patients with NSCLC were 88% (95% CI, 86-91), 72% (95% CI, 66-77), and 91% (95% CI, 89-93), respectively. CONCLUSIONS: This large, multicenter, pragmatic study demonstrates that cytology samples obtained from EBUS-TBNA in routine practice are suitable for subtyping of NSCLC and EGFR mutation analysis and that the use of immunohistochemistry reduces the rate of NSCLC-NOS.

Endobronchial ultrasound-guided transbronchial needle aspiration for the diagnosis of intrathoracic lymphadenopathy in patients with extrathoracic malignancy: a multicenter study.

INTRODUCTION: Mediastinal lymphadenopathy in patients with an extrathoracic malignancy is a common clinical scenario. Invasive sampling of intrathoracic lymph nodes may be performed by mediastinoscopy or endoscopic ultrasound-guided fine needle aspiration. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an alternative to mediastinoscopy and endoscopic ultrasound in patients with lung cancer and sarcoidosis. The utility of EBUS-TBNA in patients with extrathoracic malignancy was evaluated. METHODS: Consecutive patients who were suspected to have intrathoracic lymph node metastases from an extrathoracic malignancy underwent EBUS-TBNA. When EBUS-TBNA did not provide a specific diagnosis, patients underwent mediastinoscopy or clinical follow-up of at least 6 months duration. RESULTS: One hundred sixty-one patients meeting the inclusion criteria underwent EBUS-TBNA in five UK centers over a 3-year period. EBUS-TBNA diagnosed mediastinal or hilar metastases in 71 (44%) patients, new lung cancer in 20 (12%) patients, and sarcoidosis in 14 (9%) patients. The sensitivity, negative predictive value for malignancy, and overall accuracy for EBUS-TBNA were 87%, 73% and 88%, respectively. One hundred ten (68%) patients in the study had a final diagnosis of malignant intrathoracic lymphadenopathy. CONCLUSION: Because of the high prevalence of alternative diagnoses, pathological evaluation is important in patients with extrathoracic malignancy and suspected mediastinal or hilar lymph node metastases. EBUS-TBNA is a safe and sensitive technique and may be considered a first-line investigation in these patients.

The novel use of fast track CT to select patients for lung cancer clinics: effect on clinic efficiency, waiting times, and patient satisfaction.

BACKGROUND: Lung cancer is the most common cause of cancer death in the UK, and triaging patients 'straight to test' is recommended to improve patient experience and outcomes. While such pathways are likely to lead to earlier diagnosis and treatment, the data to support this assumption are limited. OBJECTIVES: To assess the impact of a fast track CT pathway to select patients for lung cancer clinics on clinic efficiency, diagnostic and treatment delays, and patient satisfaction. METHODS: Retrospective comparative cohort study of patients referred to lung cancer clinics for investigation of suspicious imaging from January to December 2006 and June to December 2007. RESULTS: The proportion of patients seen in clinic subsequently diagnosed with lung cancer increased from 124/399 (31%) to 86/168 (51%) (p<0.001). Time from referral to diagnosis reduced from 22 to 17 days (p<0.001). Time from referral to first discussion at the multidisciplinary team (MDT) meeting fell from 32 to 22 days (p<0.001). Time from referral to decision to treat reduced from 42 to 35 days (p<0.05). Time from referral to first treatment fell from 55 to 49 days (p=0.095). The proportion of patients who felt the diagnostic process took too long fell from 15/80 (19%) to 3/49 (6%) (p<0.05). CONCLUSIONS: The new pathway led to more effective use of clinic appointments, reduced diagnostic delay, and more rapid treatment decision times. Patient satisfaction with the speed of the diagnostic process increased. It is recommended that hospital trusts in England consider adopting similar 'straight to test' triaging to select patients for lung cancer clinics.
