Lung cancer in England: Information from the National Lung Cancer Audit (LUCADA)

AIMS Our aims were to determine whether the information in the National Lung Cancer Audit database (LUCADA) is influenced by the completeness of reporting and to describe the current socio-demographics and survival of people with lung cancer in England. METHODS Using national registry data as a gold standard we stratified NHS Trusts into quartiles on the basis of their patient ascertainment. We assessed the distribution of patient features across these quartiles using Cox and logistic regression. We then examined overall survival and access to treatment. RESULTS We analysed data for 60,059 patients whose data were entered between 2004 and 2008. There was little variation in key patient features, treatment and median survival across quartiles of data completeness. Socio-economic disadvantage did not influence survival or access to surgery but was related to a decreased use of chemotherapy. CONCLUSION Our findings suggest that LUCADA accurately describes people in England who are diagnosed with lung cancer and can therefore be used to drive health care improvements. Individual patient socio-economic status does not affect survival and has only a limited impact on access to treatment and so NHS Trust level factors should be studied to explain the previously published regional variations in these outcomes.

Inequalities in outcomes for non-small cell lung cancer: the influence of clinical characteristics and features of the local lung cancer service

Background The treatment given to patients with lung cancer and survival vary between and within countries. The National Lung Cancer Audit (NLCA) linked to Hospital Episode Statistics was used to quantify the extent to which these outcomes are influenced by patient features and/or hospital facilities and performance indicators. Methods All patients with a histological diagnosis of non-small cell lung cancer (NSCLC) were included. Logistic regression was used to quantify the independent influence of features of both patients and hospitals on the likelihood of having surgery and Cox regression was used for survival analyses. Results There were 34 513 patients with NSCLC in our dataset. After adjusting for age, sex, performance status, stage and Charlson Index of comorbidity, patients with NSCLC first seen in thoracic surgical centres (27% of the cohort) were 51% more likely to have surgery than those seen in non-surgical centres (adjusted OR 1.51, 95% CI 1.16 to 1.97). Resection rates varied from 13% to 17% between non-surgical and thoracic surgical centres. Surgery was the most powerful determinant of overall survival (adjusted HR 0.41, 95% CI 0.39 to 0.44). Conclusion A minority of patients with NSCLC first seen in a thoracic surgical centre are more likely to have surgery and to benefit from the survival advantage this confers. This finding suggests that there is an opportunity to improve the outcome for patients with lung cancer in England by optimising access to thoracic surgeons in non-surgical centres.

How do patient and hospital features influence outcomes in small-cell lung cancer in England?

Background:Our aim was to systematically determine how features of patients and hospitals influence access to chemotherapy and survival for people with small-cell lung cancer in England.Methods:We linked the National Lung Cancer Audit and Hospital Episode Statistics and used multiple logistic and Cox regression analyses to assess the influence of patient and hospital features on small-cell lung cancer outcomes.Results:There were 7845 patients with histologically proven small-cell lung cancer. Sixty-one percent (4820) of the patients received chemotherapy. Increasing age, worsening performance status, extensive stage and greater comorbidity all reduced the likelihood of receiving chemotherapy. There was wide variation in access to chemotherapy between hospitals in general and patients first seen in centres with a strong interest in clinical trials had a higher odds of receiving chemotherapy (adjusted odds ratio 1.42, 95% confidence interval (CI) 1.06, 1.90). Chemotherapy was associated with a lower mortality rate (adjusted hazard ratio 0.51, 95% CI 0.46, 0.56).Conclusion:Patients first seen at a hospital with a keen interest in clinical trials are more likely to receive chemotherapy, and chemotherapy was associated with improved survival.

Lung cancer survival in England: trends in non-small-cell lung cancer survival over the duration of the National Lung Cancer Audit.

Background:In comparison with other European and North American countries, England has poor survival figures for lung cancer. Our aim was to evaluate the changes in survival since the introduction of the National Lung Cancer Audit (NLCA).Methods:We used data from the NLCA to identify people with non-small-cell lung cancer (NSCLC) and stratified people according to their performance status (PS) and clinical stage. Using Cox regression, we calculated hazard ratios (HRs) for death according to the year of diagnosis from 2004/2005 to 2010; adjusted for patient features including age, sex and co-morbidity. We also assessed whether any changes in survival were explained by the changes in surgical resection rates or histological subtype.Results:In this cohort of 120 745 patients, the overall median survival did not change; but there was a 1% annual improvement in survival over the study period (adjusted HR 0.99, 95% confidence interval (CI) 0.98–0.99). Survival improvement was only seen in patients with good PS and early stage (adjusted HR 0.97, 95% CI 0.95–0.99) and this was partly accounted for by changes in resection rates.Conclusion:Survival has only improved for a limited group of people with NSCLC and increasing surgical resection rates appeared to explain some of this improvement.

The impact of the ‘hub and spoke’ model of care for lung cancer and equitable access to surgery

Objectives To determine the influence of where a patient is first seen (either surgical or non-surgical centre) and patient features on having surgery for non-small cell lung cancer (NSCLC). Design Cross-sectional study from individual patients, between 1January 2008 and 31March 2012. Setting Linked National Lung Cancer Audit and Hospital Episode Statistics datasets. Participants 95 818 English patients with a diagnosis of NSCLC, of whom 12 759 (13%) underwent surgical resection. Main outcome measure Odds of having surgery based on the empirical catchment population of the 30 thoracic surgical centres in England and whether the patient is first seen in a surgical centre or a non-surgical centre. Results Patients were more likely to be operated on if they were first seen at a surgical centre (OR 1.37; 95% CI 1.29 to 1.45). This was most marked for surgical centres with the largest catchment populations. In these surgical centres with large catchment populations, the resection rate for local patients was 18% and for patients first seen in a non-surgical centre within catchment was 12%. Conclusions Surgical centres that serve the largest catchment populations have high resection rates for patients first seen in their own centre but, in contrast, low resection rates for patients first seen at the surrounding centres they serve. Our findings demonstrate the importance of going further than relating resection rates to hospital volume or surgeon number, and show that there is a pressing need to design lung cancer services which enable all patients, including those first seen at non-surgical centres, to have equal access to lung cancer surgery.

Treatment patterns and survival analysis in 9014 patients with malignant pleural mesothelioma from Belgium, the Netherlands and England

INTRODUCTION Pleural mesothelioma has a dismal prognosis and is refractory to local treatment. Combination chemotherapy can increase median survival by several months and was gradually introduced in the period 2003-2006. Elderly patients may be unfit for chemotherapy but little is known about age-related treatment practice. To determine treatment patterns and current survival outcome, three large population-based registries were queried in a uniform manner. METHODS Data from the Belgian Cancer Registry, the Netherlands Cancer Registry and the UK National Lung Cancer Audit were analyzed for patients diagnosed with pleural mesothelioma since 2007. Treatment patterns and survival rates were compared between countries and age-groups. RESULTS The study included 900, 2306 and 5808 patients from Belgium, the Netherlands and England, respectively. Fifty-nine percent of patients were 70 years or older and 84% were men. Chemotherapy use decreased with advancing age and was used more often in Belgium (60%) than in the Netherlands (41%) and England (37%). For patients aged 70-79 years, chemotherapy use was 55%, 36% and 34% in the respective countries. Median survival was 10.7 months in Belgium versus 9.2 months for the Netherlands and 9.5 months for England. Survival rates decreased with advancing age. On average, median survival was 5.6 months longer for patients treated with chemotherapy, irrespective of age. CONCLUSIONS Combined analysis of data from three countries with high mesothelioma rates demonstrates that chemotherapy has become standard treatment for younger patients. Elderly patients currently account for more than half of all cases and less toxic treatment options will be required to improve their prospects.

Small-Cell Lung Cancer in England: Trends in Survival and Chemotherapy Using the National Lung Cancer Audit

Background The purpose of this study was to identify trends in survival and chemotherapy use for individuals with small-cell lung cancer (SCLC) in England using the National Lung Cancer Audit (NLCA). Methods We used data from the NLCA database to identify people with histologically proven SCLC from 2004–2011. We calculated the median survival by stage and assessed whether patient characteristics changed over time. We also assessed whether the proportion of patients with records of chemotherapy and/or radiotherapy changed over time. Results 18,513 patients were diagnosed with SCLC in our cohort. The median survival was 6 months for all patients, 1 year for those with limited stage and 4 months for extensive stage. 69% received chemotherapy and this proportion changed very slightly over time (test for trends p = 0.055). Age and performance status of patients remained stable over the study period, but the proportion of patients staged increased (p-value<0.001), mainly because of improved data completeness. There has been an increase in the proportion of patients that had a record of receiving both chemotherapy and radiotherapy each year (from 19% to 40% in limited and from 9% to 21% in extensive stage from 2004 to 2011). Patients who received chemotherapy with radiotherapy had better survival compared with any other treatment (HR 0.24, 95% CI 0.23–0.25). Conclusion Since 2004, when the NLCA was established, the proportion of patients with SCLC having chemotherapy has remained static. We have found an upward trend in the proportion of patients receiving both chemotherapy and radiotherapy which corresponded to a better survival in this group, but as it only applied for a small proportion of patients, it was not enough to change the overall survival.

The pathological confirmation rate of lung cancer in England using the NLCA database

BACKGROUND The National Lung Cancer Audit (NLCA) recommends that trusts obtain pathology (histology or cytology) for 75% of their lung cancer patients, however this figure was arbitrarily chosen and the optimal pathological confirmation rate is unknown, and many countries report somewhat higher rates. The aims of this study were to provide a simple means of benchmarking appropriate pathological confirmation rates by stratifying patients into groups, and whether obtaining pathology based on those groups is associated with a survival benefit. METHODS We calculated the proportion of patients with non-small cell or small cell lung cancer in the NLCA database, first seen between 1st January 2004 and 31st December 2010, who had pathological confirmation of their diagnosis. Using logistic we assessed the independent influence of patient factors on the likelihood of having histology or cytology, and the overall effect on survival. We also used bivariate analysis to identify the features which were most strongly associated with having pathology and performed Cox regression to identify any survival advantage. FINDINGS We analysed data on 136,993 individuals. Age and performance status (PS) were the strongest predictors of pathological confirmation: age ≥ 85 odds ratio (OR) 0.20 (95% confidence interval (CI) 0.19-0.22) compared with age<55; PS 4 OR 0.11 (95%CI 0.10-0.12) compared with PS 0. Pathological confirmation of diagnosis was associated with a small early survival advantage for groups 1 & 2 which represented younger patients with good PS, even after adjusting for other patient features: hazard ratio (HR) 0.93 & 0.89 respectively. CONCLUSION Stratifying patients by age and performance status is useful and appropriate when benchmarking standards for pathological confirmation of the diagnosis of lung cancer. We have shown better survival at six months and one year for younger patients with better PS, even after adjusting for confounders. Much of the survival advantage was accounted for by adjusting for the use of chemotherapy.

Non-small cell lung cancer in young adults: presentation and survival in the English National Lung Cancer Audit

BACKGROUND Non-small cell lung cancer (NSCLC) in young adults is a rare but devastating illness with significant socioeconomic implications, and studies of this patient subgroup are limited. AIM This study employed the National Lung Cancer Audit to compare the clinical features and survival of young adults with NSCLC with the older age groups. DESIGN A retrospective cohort review using a validated national audit dataset. METHODS Data were analysed for the period between 1 January 2004 and 31 December 2011. Young adults were defined as between 18 and 39 years, and all others were divided into decade age groups, up to the 80 years and above group. We performed logistic and Cox regression analyses to assess clinical outcomes. RESULTS Of a total of 1 46 422 patients, 651 (0.5%) were young adults, of whom a higher proportion had adenocarcinoma (48%) than in any other age group. Stage distribution of NSCLC was similar across the age groups and 71% of young patients had stage IIIb/IV. Performance status (PS) was 0-1 for 85%. Young adults were more likely to have surgery and chemotherapy compared with the older age groups and had better overall and post-operative survival. The proportion with adenocarcinoma, better PS and that receiving surgery or chemotherapy diminished progressively with advancing decade age groups. CONCLUSION In our cohort of young adults with NSCLC, the majority had good PS despite the same late-stage disease as older patients. They were more likely to have treatment and survive longer than older patients.

Status of Lung Cancer Data Collection in Europe

The European Union (EU) began as the European Economic Community (EEC) in 1967 with six founder members: Belgium, the Federal Republic of Germany, France, Italy, Luxembourg, and the Netherlands. The first expansion of the EEC was in 1973, when Denmark, Ireland, and the United Kingdom joined, followed by Greece in 1981 and then Portugal and Spain in 1986.1 The composition and function of the EU have changed dramatically during the past 30 years along with several major political events. These include the fall of the Berlin wall (1989), the dissolution of the Union of Soviet States of Russia (1991), the division of Czechoslovakia (1993), and the break-up of Yugoslavia into seven independent countries (war torn period, 1991-2001). The number of independent countries in Europe has almost doubled, and the number members of the EU has increased from 12 to 28 (Appendix Table A1).
