RESUMEN

BACKGROUND: Stage at diagnosis is a key predictor of overall cancer outcome. For the first time, stage completeness is high enough for robust analysis for the whole of England. METHODS: We analysed data from the National Cancer Registration Service's (NCRS) Cancer Analysis System on persons diagnosed with breast, colorectal, lung, prostate or ovarian cancers in England in 2012. One-year relative survival (followed-up to the end of 2013) was calculated along with adjusted excess rate ratios, for mortality within 1 year. RESULTS: One-year relative survival decreased with increasing stage at diagnosis. For breast, prostate and colorectal cancers survival showed a major reduction for stage 4 cancers, whereas for lung and ovarian cancers there were substantial decreases in relative survival for each level of increase in stage. Excess rate ratios for mortality within 1 year of diagnosis showed that stage and age were the most important cofactors, but they also identified the statistically significant effects of sex, income deprivation and geographic area of residence. CONCLUSIONS: Further reductions in mortality may be most effectively achieved by diagnosing all cancers before they progress to stage 4, but for lung and ovarian cancers there is also a need for a stage shift to earlier stages together with efforts to improve stage-specific survival at all stages.

RESUMEN

BACKGROUND: Survival rates in lung cancer in England are significantly lower than in many similar countries. A range of Be Clear on Cancer (BCOC) campaigns have been conducted targeting lung cancer and found to improve the proportion of diagnoses at the early stage of disease. This paper considers the cost-effectiveness of such campaigns, evaluating the effect of both the regional and national BCOC campaigns on the stage distribution of non-small-cell lung cancer (NSCLC) at diagnosis. METHODS: A natural history model of NSCLC was developed using incidence data, data elicited from clinical experts and model calibration techniques. This structure is used to consider the lifetime cost and quality-adjusted survival implications of the early awareness campaigns. Incremental cost-effectiveness ratios (ICERs) in terms of additional costs per quality-adjusted life-years (QALYs) gained are presented. Two scenario analyses were conducted to investigate the role of changes in the 'worried-well' population and the route of diagnosis that might occur as a result of the campaigns. RESULTS: The base-case theoretical model found the regional and national early awareness campaigns to be associated with QALY gains of 289 and 178 QALYs and ICERs of £13 660 and £18 173 per QALY gained, respectively. The scenarios found that increases in the 'worried-well' population may impact the cost-effectiveness conclusions. CONCLUSIONS: Subject to the available evidence, the analysis suggests that early awareness campaigns in lung cancer have the potential to be cost-effective. However, significant additional research is required to address many of the limitations of this study. In addition, the estimated natural history model presents previously unavailable estimates of the prevalence and rate of disease progression in the undiagnosed population.

RESUMEN

INTRODUCTION: Long-term lung cancer survival in England has improved little in recent years and is worse than many countries. The Department of Health funded a campaign to raise public awareness of persistent cough as a lung cancer symptom and encourage people with the symptom to visit their GP. This was piloted regionally within England before a nationwide rollout. METHODS: To evaluate the campaign's impact, data were analysed for various metrics covering public awareness of symptoms and process measures, through to diagnosis, staging, treatment and 1-year survival (available for regional pilot only). RESULTS: Compared with the same time in the previous year, there were significant increases in metrics including: public awareness of persistent cough as a lung cancer symptom; urgent GP referrals for suspected lung cancer; and lung cancers diagnosed. Most encouragingly, there was a 3.1 percentage point increase (P<0.001) in proportion of non-small cell lung cancer diagnosed at stage I and a 2.3 percentage point increase (P<0.001) in resections for patients seen during the national campaign, with no evidence these proportions changed during the control period (P=0.404, 0.425). CONCLUSIONS: To our knowledge, the data are the first to suggest a shift in stage distribution following an awareness campaign for lung cancer. It is possible a sustained increase in resections may lead to improved long-term survival.

RESUMEN

We report the findings of the first national lung cancer organisational audit. The results demonstrate marked variation in service provision and workload of some lung cancer specialists. For example, over half of the clinical nurse specialists report case volumes over recommended numbers. Some trusts have no access to key treatments such as video assisted thoracoscopy (VAT) lobectomy and stereotactic radiotherapy. Multivariate regression analysis demonstrated an association between higher surgical resection rates and the on-site availability of advanced staging and therapeutic modalities, for example, PET scan and VAT lobectomy. We conclude by making a number of recommendations to address the variation in lung cancer care.

RESUMEN

BACKGROUND: Results from the National Lung Cancer Audit demonstrate unexplained variation in outcomes. Peer review with supported quality improvement has been shown to reduce variation in other areas of health care but has not been formally tested in cancer multidisciplinary teams. The aim of the current study is to assess the impact of reciprocal peer-to-peer review visits with supported quality improvement and collaborative working on lung cancer process and outcome measures. METHODS: English lung cancer teams were randomised to usual care or facilitated reciprocal peer review visits followed by 12 months of supported quality improvement. The primary outcome was change in the following national audit indicators; mulitdisciplinary team discussion, histological confirmation, active treatment, surgical resection, small-cell chemotherapy and specialist nurse review. Patient experience was measured using a new lung cancer patient questionnaire in the intervention group. RESULTS: Thirty teams (31 trusts) entered the intervention group and 29 of these submitted a total of 67 quality improvement plans. Active treatment increased in the intervention group (n=31) by 5.2% compared with 1.2% in the control group (n=48, mean difference 4.1%, 95% CI -0.1 to 8.2%, P=0.055). The remaining audit indicators improved similarly in all groups. Mean patient experience scores in the intervention group did not change significantly during the study but a significant improvement was seen in the scores for the five teams with the worst baseline scores (0.86 to 0.22, P<0.001). CONCLUSIONS: Reciprocal peer review with supported quality improvement was feasible and effective in stimulating quality improvement activity but resulted in only modest improvements in lung cancer treatment rates and patient experience.

RESUMEN

AIMS: To describe the prevalence of cardiovascular disease (CVD), multiple comorbidities and social deprivation in patients with a potentially curable cancer in 20 English Cancer Alliances. MATERIALS AND METHODS: This National Registry Dataset Analysis used national cancer registry data and CVD databases to describe rates of CVD, comorbidities and social deprivation in patients diagnosed with a potentially curable malignancy (stage I-III breast cancer, stage I-III colon cancer, stage I-III rectal cancer, stage I-III prostate cancer, stage I-IIIA non-small cell lung cancer, stage I-IV diffuse large B-cell lymphoma, stage I-IV Hodgkin lymphoma) between 2013 and 2018. Outcome measures included observation of CVD prevalence, other comorbidities (evaluated by the Charlson Comorbidity Index) and deprivation (using the Index of Multiple Deprivation) according to tumour site and allocation to Cancer Alliance. Patients were allocated to CVD prevalence tertiles (minimum: <33.3rd percentile; middle: 33.3rd to 66.6th percentile; maximum: >66.6th percentile). RESULTS: In total, 634 240 patients with a potentially curable malignancy were eligible. The total CVD prevalence for all cancer sites varied between 13.4% (CVD n = 2058; 95% confidence interval 12.8, 13.9) and 19.6% (CVD n = 7818; 95% confidence interval 19.2, 20.0) between Cancer Alliances. CVD prevalence showed regional variation both for male (16-26%) and female patients (8-16%) towards higher CVD prevalence in northern Cancer Alliances. Similar variation was observed for social deprivation, with the proportion of cancer patients being identified as most deprived varying between 3.3% and 32.2%, depending on Cancer Alliance. The variation between Cancer Alliance for total comorbidities was much smaller. CONCLUSION: Social deprivation, CVD and other comorbidities in patients with a potentially curable malignancy in England show significant regional variations, which may partly contribute to differences observed in treatments and outcomes.

RESUMEN

The National Lung Cancer Audit was developed to improve the quality and outcomes of services for patients with lung cancer, knowing that outcomes vary widely across the UK and are poor compared to other western countries. After five years the audit is capturing approximately 100% of the expected number of incident cases across hospitals in England, Wales, Scotland, Northern Ireland and Jersey. Measures of process and outcome have improved over the audit period, such as the histological confirmation rate (64-76%), the proportion of patients discussed in a multidisciplinary team meeting (78-94%), and the proportion of patients having anti-cancer treatment (43-59%), surgical resection (9-14%) and small cell lung cancer chemotherapy (58-66%). These national averages hide wide variations between hospitals providing lung cancer care which cannot be accounted for by differences in casemix. This paper describes the evolution of the audit, and describes the ways in which it may have improved clinical practice.

RESUMEN

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.

RESUMEN

BACKGROUND: Initial studies on the use of ultrasound in the detection and sampling of supraclavicular lymph nodes in patients with suspected lung cancer show this to be a promising technique, giving both a cytological diagnosis and pathological N3 (pN3) stage. Leicester published its initial experience in 2005 and the aim of this study was to establish if this had been embedded into the diagnostic pathway, and further to examine the use of ultrasound in diagnosing and staging lung cancer by imaging other areas including pleural effusions, chest wall, bone and liver lesions. METHODS: All patients diagnosed with lung cancer, registered on the Leicester lung cancer database over a two year period between January 2007 and December 2008, had their imaging and pathology retrospectively reviewed; 996 primary lung cancer patients were identified (n=996). Of these, 318 patients underwent an ultrasound examination (n=318), consisting of ultrasound of the neck, pleural cavity, and metastatic lesions potentially amenable to ultrasound guided aspiration/biopsy. RESULTS: The overall malignant yield was 45% of patients scanned (95% CI 39.5% to 50.4%) and 81.3% of patients sampled (95% CI 75.5% to 87%). Of the 996 patients, 14.4% (n=143) had a positive ultrasound guided cytological diagnosis (95% CI 12.2% to 16.5%). Of all the pathological diagnoses (n=765), 18.7% were ultrasound guided (95% CI 15.9% to 21.5%). In particular, 32.2% of patients with CT detected neck or mediastinal nodes had a diagnosis and stage achieved by neck ultrasound. CONCLUSION: The use of ultrasound gives a rapid and less invasive method of diagnosing and staging lung cancer and has become embedded into the diagnostic pathway. We advocate its increased use and availability in patients with lung cancer.

RESUMEN

BACKGROUND: A previous study showed that lung cancer incidence in Leicester's South Asian (SA) population had increased between 1990 and 1999. We expanded the original data set to determine if this increase had continued in recent years. METHODS: All patients diagnosed with lung cancer in Leicester between 1990 and 2005 were identified. Ethnicity was assigned using Nam Pechan software, deprivation by Townsend score. Using Poisson regression, incidence rate ratios (IRRs) were calculated to assess variations in incidence by ethnicity, deprivation and period of diagnosis. RESULTS: Comparing patients diagnosed in 2000-2005 with those in 1990-1994, the risk of lung cancer increased in the SA men (IRR: 1.67 (95% CI: 0.99, 2.78)) whereas in the non-South Asian (NSA) men, it had fallen (IRR: 0.84 (95% CI: 0.76, 0.94)). Comparing patients diagnosed in 2000-2005 with those in 1995-1999 an increase continued in the SA men (IRR: 1.11 (95% CI: 0.71-1.74)). A significant rise was observed in the NSA women comparing those diagnosed from 2000-2005 to 1995-1999 (IRR: 1.16 (95% CI: 1.01, 1.33)). CONCLUSION: Lung cancer is an important public health issue amongst SAs in Leicester and has increased significantly since the early 1990s, with rates sustained in the more recent years of 2000-2005. Changes in the rates of lung cancer in SA and NSA populations are likely to be due to changing smoking habits.

RESUMEN

This study was designed to assess the cost-effectiveness of erlotinib compared with docetaxel in the second-line management of advanced non-small-cell lung cancer (NSCLC) within the UK National Health Service (NHS). A health-state transition model, based on two randomized phase III studies of erlotinib or docetaxel versus best supportive care, was used to estimate total direct costs, quality-adjusted life years (QALYs) and the subsequent net monetary benefit. Erlotinib was associated with a reduction in total costs ( pound13 730 versus pound13 956) and improved outcomes (total QALYs of 0.238 versus 0.206) compared with docetaxel. Sensitivity analyses demonstrated the robustness of this analysis. In summary, erlotinib appeared to generate similar overall survival, an increase in QALYs and a small reduction in total NHS costs compared with docetaxel, due to lower adverse event and drug administration costs. Consequently, from a health economics perspective for the treatment of relapsed stage III - IV NSCLC patients in the UK, erlotinib has advantages over docetaxel.

RESUMEN

Survival from lung cancer has seen only modest improvements in recent decades. Poor outcomes are linked to late presentation, yet early diagnosis can be challenging as lung cancer symptoms are common and non-specific. In this paper, we examine how lung cancer presents in primary care and review roles for primary care in reducing the burden from this disease. Reducing rates of smoking remains, by far, the key strategy, but primary care practitioners (PCPs) should also be pro-active in raising awareness of symptoms, ensuring lung cancer risk data are collected accurately and encouraging reluctant patients to present. PCPs should engage in service re-design and identify more streamlined diagnostic pathways-and more readily incorporate decision support into their consulting, based on validated lung cancer risk models. Finally, PCPs should ensure they are central to recruitment in future lung cancer screening programmes-they are uniquely placed to ensure the right people are targeted for risk-based screening programmes. We are now in an era where treatments can make a real difference in early-stage lung tumours, and genuine progress is being made in this devastating illness-full engagement of primary care is vital in effecting these improvements in outcomes.

RESUMEN

PURPOSE: The Big Lung Trial (BLT) was a large, pragmatic trial to evaluate the addition of chemotherapy to primary treatment (ie, surgery, radical radiotherapy, or supportive care) in non-small-cell lung cancer (NSCLC). In the supportive care group, there was a small but significant survival benefit in patients treated with chemotherapy compared with supportive care alone (no chemotherapy). A substudy was undertaken to evaluate the quality of life (QoL) implications of the treatment options. QoL was assessed using European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaires C30 (QLQ-C30) and LC17, and daily diary cards. PATIENTS AND METHODS: EORTC QLQ-C30 and LC17 were collected at 0, 6 to 8, 12, 18, and 24 weeks. Diary cards were completed during the first 12 weeks of the study. The primary end point was global QoL at 12 weeks. RESULTS: A total of 273 patients were randomly assigned: 138 to no chemotherapy and 135 to chemotherapy. There was no evidence of a large detrimental effect on QoL of chemotherapy. No statistically significant differences in global QoL or physical/emotional functioning, fatigue and dyspnea, and pain were detected at 12 weeks. Higher rates of palliative radiotherapy in the no chemotherapy arm may have lessened differences in QoL. Global QoL, role functioning, fatigue, appetite loss, and constipation were prognostic indicators of survival at 12 weeks. CONCLUSION: There were no important adverse effects of chemotherapy on QoL.

RESUMEN

INTRODUCTION: Histological diagnosis of malignant mesothelioma requires an invasive procedure such as CT-guided needle biopsy, thoracoscopy, video-assisted thorascopic surgery (VATs) or thoracotomy. These invasive procedures encourage tumour cell seeding at the intervention site and patients can develop tumour nodules within the chest wall. In an effort to prevent nodules developing, it has been widespread practice across Europe to irradiate intervention sites postprocedure--a practice known as prophylactic irradiation of tracts (PIT). To date there has not been a suitably powered randomised trial to determine whether PIT is effective at reducing the risk of chest wall nodule development. METHODS AND ANALYSIS: In this multicentre phase III randomised controlled superiority trial, 374 patients who can receive radiotherapy within 42 days of a chest wall intervention will be randomised to receive PIT or no PIT. Patients will be randomised on a 1:1 basis. Radiotherapy in the PIT arm will be 21 Gy in three fractions. Subsequent chemotherapy is given at the clinicians' discretion. A reduction in the incidence of chest wall nodules from 15% to 5% in favour of radiotherapy 6 months after randomisation would be clinically significant. All patients will be followed up for up to 2 years with monthly telephone contact and at least four outpatient visits in the first year. ETHICS AND DISSEMINATION: PIT was approved by NRES Committee North West-Greater Manchester West (REC reference 12/NW/0249) and recruitment is currently on-going, the last patient is expected to be randomised by the end of 2015. The analysis of the primary end point, incidence of chest wall nodules 6 months after randomisation, is expected to be published in 2016 in a peer reviewed journal and results will also be presented at scientific meetings and summary results published online. A follow-up analysis is expected to be published in 2018. TRIAL REGISTRATION NUMBER: ISRCTN04240319; NCT01604005; Pre-results.

RESUMEN

A prospective randomized controlled trial was performed comparing the use of a short period (24 hr) of postextubation nasal continuous positive airways pressure (CPAP) with direct extubation into headbox oxygen on the outcome of the need for reintubation within 7 days of initial extubation. Infants at less than 32 weeks of gestation who had received mechanical ventilation in the first 28 postnatal days and were being extubated for the first time were recruited. Ninety-seven babies were entered into the study (48 CPAP and 49 headbox oxygen). Twenty-four (49%) babies in the headbox group were reventilated within a week, compared to 16 (33%) in the CPAP group (P=0.17). By 14 days after initial extubation, 25 babies (51%) in the headbox group and 23 (48%) in the CPAP group required reventilation (P=0.9). There was a trend toward babies in the CPAP group requiring fewer reintubations (median, 2; range, 1-6) compared to those in the headbox group (median, 3; range, 1-7) (P=0.063). There was no significant difference between groups with respect to total number of days of ventilation (headbox median, 4; range, 1-24; CPAP median, 2; range, 1-20). In conclusion, this study showed that a short period of nasal CPAP is not associated with a reduction in reventilation.

RESUMEN

INTRODUCTION AND METHODS: Malignant pleural mesothelioma (MPM) is an uncommon cancer with poor survival. We have used data collected for the UK National Lung Cancer Audit to assess current practice and to highlight regional variation in the management of mesothelioma patients, as well as to describe survival patterns in subgroups. RESULTS: Our data on 8740 cases seen in hospitals in England and Wales is the largest cohort of MPM in the literature and represents approximately 80% of the total incident cases. 83% are male and median age is 73 years. Performance status is recorded in 81% and of these approximately 70% are PS 0-2. Stage is poorly recorded and unreliable in this dataset. The patient pathway is similar to lung cancer with approximately one-fifth having a non-elective referral to secondary care. A histo-cytological diagnosis is made in 87% and varies across organisations. Only 67% have anti-cancer treatment, and this also varies across organisations, but there has been an annual increase in the proportion receiving chemotherapy. Overall median survival was 9.5 months, with a 1YS of 41.4% and 3YS of 12.0%, but was strongly linked to performance status and histological subtype. Median survival also varied by cancer network from 209 days to 349 days, but appeared to increase from of 9.2 months in 2008 to 10.5 months in 2012. CONCLUSION: Our data provide a large scale, detailed assessment of MPM epidemiology, treatment choices and outcomes. Incidence is increasing in line with predictions and uptake of treatments has generally mirrored publication of key MPM treatment trials, in particular increasing use of chemotherapy but low uptake of radical surgery. However, there is significant variation in care patterns and outcomes that may reflect limited expertise in area with low incidence. Initiatives to improve outcomes should include improved recording of clinical stage.

RESUMEN

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.

RESUMEN

The role of ecdysteroids in modulating exoskeletal growth during the moult cycle of Crustacea has been well described. However, little is known about the action of ecdysteroids at the level of gene transcription and regulation in Crustacea. This paper reports the cloning of an ecdysteroid responsive gene, HHR3, a potential Manduca sexta MHR3 homologue in the American lobster, Homarus americanus. Levels of HHR3 expression are up-regulated in response to in vivo injections of premoult concentrations (10(-6) M) of 20-hydroxyecdysone in the epidermal and muscle tissue of the lobster after 6 h. Maximal mRNA levels are observed after 21 h before returning to basal levels. In muscle tissue, elevated levels of HHR3 mRNA follow a time course similar to elevated actin mRNA expression in response to hormonal injection. In contrast, in eyestalk tissue, the HHR3 levels decline up to 21 h post-injection before rising to basal levels after 48 h. Eyestalk, epidermal and leg muscle tissue was extracted over the moult cycle to determine the levels of expression. In muscle, HHR3 is high during the premoult period that corresponds to the period of the moult cycle when the ecdysteroid titre is high. In the epidermis, HHR3 levels are also high during the premoult with elevated levels maintained into the postmoult period. In the eyestalk, mRNA levels of HHR3 show an opposite pattern of expression with low levels during premoult and postmoult and high levels found during the intermoult period. Our results provide novel evidence for an ecdysteroid responsive gene in a crustacean that has many similarities to MHR3 in Manduca and DHR3 in Drosophila melanogaster. This raises the question of whether a similar cascade of ecdysteroid responsive genes exist in other members of Arthropoda such as the Crustacea, as has been demonstrated in Drosophila. In addition, we provide further evidence for negative feedback regulation of ecdysteroids at the site of moult-inhibiting hormone (MIH) production in the lobster eyestalk.
